Organocide® 3-in-1 Garden Spray — a favorite to so many. FAQs

Since we first introduced Organocide® 3-in-1 Garden Spray back in 1996, we have received hundreds and possibly thousands of positive reviews. It’s certainly a favorite among organic growers and its popularity continues to grow today. Along with those reviews, we’ve received some commonly asked questions that we thought would be helpful to share in today’s blog.

If you have any further questions about this or any of our other products, please be sure to drop us a note in our “Contact Us” area. We’re happy to reply…you’re the reason we’re here!

Here are your FAQs:
How does Organocide® 3-in-1 Garden Spray work?
  • Dense oil spray smothers target insects on contact. The fatty acids in the oil are toxic to the target insects and they are unable to develop a resistance.
  • Once liquid dries, a micro-film is left on the plant. Any hatchlings of the target insects get trapped in the film and die.
  • Females arriving after treatment detect the film and will not lay eggs on the treated plant; recognizing the area as hazard to their eggs.
What insects will Organocide® 3-in-1 Garden Spray control?
  • It kills the eggs, larvae, nymphs and adult stages of over 25 soft bodied insects including (but not limited to) aphids, chinch bugs, citrus rust mites, flea larvae, fungus gnats, hemlock wooly adelgid, leaf-rollers, mealy bugs, psyllids, scale, spider mites, thrips, and whiteflies1.
Will it kill bees or butterflies?
  • It is soft on Beneficial Insects – it will NOT harm Bees, Butterflies or Ladybugs.
What fungicidal properties does Organocide® 3-in-1 Garden Spray have?
  • It controls certain fungal diseases such as (but not limited to) powdery mildew, downy mildew, black spot on roses, septora spot, bacterial tomato spot, citrus greasy spot & helminthosporium. It works by depriving the disease spore of moisture necessary for propagation and protects the plant from germ tube penetration and spreading of pathogens such as powdery mildew.
  • If spraying on severely stressed or damaged plants, split the dosage rate in half to avoid adding additional stress.
What about plant compatibility?
  • When used as directed it has an unusually high degree of safety to most plants, including herbs, fruits & vegetables. However, some plants in the Euphorbia family (Crown of Thorns, Poinsettia) have shown some sensitivity and orchids have been known to be very sensitive plants. If in doubt, test first on a small area of foliage.
When should Organocide® be applied?
  • It should be applied early morning or late evening. There is very little risk of leaf burn when applied to plants, when used as directed. Do not freeze or spray in temperatures over 95°F.
Since it’s made of fish oil, does it smell?
  • Do not confuse fish oil with fish emulsion; Organocide has a very slight fish odor that is exponentially better than fish emulsion. You will hardly notice it and the smell is gone in a couple of hours. The Ready to Use sizes are completely deodorized for in-home use.
How often should I use Organocide® 3-in-1 Spray?
  • For tough scale insects, a once-a-week application for 3 weeks should effectively eliminate the scale. For all others, it will depend upon the pressures of the environment, but in general, one or two applications per month will usually control the problem.
Does Organocide work on Citrus Greening?
    It does not control Citrus Greening, but it will control psyllids – the insect that carries the disease.
Can Organocide be used to control larvae found in the tree bark?
    Make a heavy application of Organocide to the bark of the trunk and large limbs only. The idea is to leave a thin sticky film to trap the larvae as they hatch and crawl over the bark. Start with a concentrated solution of 6 oz. per gallon of water and spray over the bark. If the bark is not sticky to the touch, keep increasing the concentration per gallon until the desired results are obtained. Keep watch at the time of larvae hatching and time your applications for best results.
Is Organocide® 3-in-1 effective after rain?
  • Yes, as long as the application has had a minimum of 3-4 hours to dry.
 What happens if my pet ingests Organocide® 3-in-1?
  • Product is NOT toxic and it’s made of food-grade oils. Unless your pet is allergic to ingredients they should not have a negative reaction. Provide extra water to keep pet hydrated, they may experience diarrhea depending on consumption.
 How long should I wait before I let my pet outside?
  • 3-4 hours so product has time to dry.
Does Organocide® 3-in-1 expire?
  • There is no defined shelf life; it will last for many years – shake well before mixing after it’s been properly stored.
How long can I store the Organocide® 3-in-1 Concentrate that I’ve mixed with water?
  • Your solution can last approximately 30-45 days because adding water introduces bacteria.
When can edible plants be harvested after spray?
  • There is no re-entry time after application and plants can be harvested right after a spray. Organocide® is made up of all food-grade oils.
There is sticky residue left on my kumquats, how can I get rid of it?
    Use a fruit and veggie wash that you can purchase at your local supermarket (in the produce section) or you can try a homemade version like the one below:
Ingredients 

1) SPRAY
1 tablespoon fresh lemon juice
1 tablespoon baking soda
1 cup water

2) SOAK
1/4 cup vinegar
2 tablespoons salt

Directions

1. SPRAY; put all ingredients into a spray bottle (be careful as it will foam up) shake gently to mix, then spray on veggies or fruit allow to sit for about 25 minutes then rinse under cold water.

2. SOAK; fill a clean sink or a large basin with cold water; add in vinegar and salt, then swish around with hands (you may also do this in a large bowl). Place the fruit and/or veggies in and allow to sit for 25-30 minutes although I have even left soaking for over an hour (this will not affect the flavor at all), the vinegar cleans and the salt draws out any little bugs, dirt and other small unwanted things, it also will remove some of the wax. Rinse under cold water and dry.

What should I do if my sprayer becomes clogged?
    After making your application of Organocide 3-in-1 Garden Spray we recommend running warm water thru the sprayer. For heavily clogged sprayers use a citrus based product (such as ZEP). Use it along with HOT water and agitate thoroughly.
What other products is it compatible with?
    You can tank mix with copper & pyrethrum and it even increases their effectiveness.
What is the application for chinch bugs on my lawn?
    Mix 5-6oz per gallon of water for every 1,000 sq. ft. and water in well.
Can I use it as a soil drench on medical marijuana plants for killing root aphids? 
    Yes, mix 3oz per gallon of water and use in soil drench once per week (to break their life cycle), until aphids are gone.
How is it available?
  • • 24 and 72oz RTU (Ready to Use)
  • • QT Concentrate
  • • Hose End RTS (Ready to Spray)
  • • 2½ Gal Jug
  • • 30 and 55 Gallon Drum
  • • 250 Gallon Tote

¹Whiteflies are the most difficult insect to control because it has such a short life span and repopulates very quickly. Organocide will kill them directly by contact but will not prevent them from coming back.

      Please do not hesitate to reach out again with additional questions.

  2. I have an active adelgid infestation on some hemlocks. Will 3-in-1 work on those, how many times will I need to use it, and can I use it with a hose-attached sprayer, as the trees are 3 stories high?

    • Dear Jonathan,

      We want to thank you for writing to us and for viewing our website.

      Our Organocide 3 in 1 Garden Spray will definitely help with the adelgid infestation on the hemlocks.

      If you’re using our concentrate (Quart), we recommend the following:
      SHAKE WELL FIRST.
      Dilute 3 oz. of Organocide® 3-in-1 Garden Spray per gallon of water and shake well to
      blend. Once blended, shake often while in use to prevent separation. Diluted solution
      can be used up to 30 days. Use a sprayer that will put out a fine spray. If spraying on
      severely stressed or damaged plants, consider using a lower rate such as 1 oz. per gallon
      to avoid adding additional stress. For best results, spray during the coolest time of the
      day (early morning or late evening) and allow 3-4 hours for product to dry. Do not apply
      when temperatures exceed 95°F. A single application is normally enough for control. For
      normal maintenance, spray once per month or as needed to spot treat areas. For severe
      problems, make two applications 3 days apart. Reapply in 7 days if problem persists.

      If you’re using the Ready To Use (Hose End), we recommend the following:
      Directions for Use:
      Do this 1st: Make sure the valve on the Sprayer Nozzle is in the “OFF” position.
      Do this 2nd: SHAKE WELL and connect to garden hose securely and turn the faucet on full force.
      Do this 3rd: Turn the Sprayer Nozzle valve to the “ON” position.
      When finished: Turn the Sprayer Nozzle valve to the “WATER” position to rinse and clean.
      For best results, spray during the coolest time of the day (early morning or late evening) and allow 3-4
      hours for product to dry. Do not apply when temperatures exceed 95°F. A single application is normally
      enough for control. For normal maintenance, spray once per month or as needed to spot treat areas. For
      severe problems, make two applications 3 days apart. Reapply in 7 days if problem persists.

  3. Will this work on a leaf miner infestation?

    • We want to thank you for writing to us and for viewing our website. We appreciate your questions and feedback.

      Unfortunately, it will not work on leaf miner.

      Please do not hesitate to reach out again with additional questions.

  4. What temperature range is recommended for using 3-in-1 for killing and controlling tea scale on camellias? If it is applied in a cooler morning or evening, what is the maximum day time temperature that can occur without harming the leaves?
    Thanks for your response?
    Rob

  5. Will this kill horn worms, and eggs?

    • We want to thank you for writing to us and for viewing our website.

      No, it will not work on worms. Organocide works on small soft bodied insects.

      Please do not hesitate to reach out again with additional questions.

  6. Will it kill cutworms?

    • We want to thank you for writing to us and for viewing our website.

      No, it will not work on worms. Organocide works on small soft bodied insects.

      Please do not hesitate to reach out again with additional questions.

  7. Can you use Organocide for leaf curl?

    • Organocide will definitely kill the white flies that causes Leaf Curl. You can definitely try it. If it does not work, try using our Organic fungicide. Organic Fungicide is a broad spectrum potassium bicarbonate-based fungicide that has been proven to cure and prevent powdery mildew, blackspot, downy mildew, blights, molds and other plant diseases.

  8. We recently put down a large amount of chipped bark, leaves, and other cuttings for a thick layer of mulching under our citrus trees and other plantings. Its great to conserve water and mulch down. We also mix in manure btw. The problem is that it attracts a large amount of fungus gnats. If we spray this product on the chips and mulch will it possibly cut down on the gnat problem? We’ve set out the obligatory cider vinegar traps but need to go bigger. Thanks!!!

    • Shawn,

      Organocide 3-in-1 Garden Spray should only be sprayed on plants. I do not recommend spraying on your mulch.

  9. The label mentioned that organocide 3in1 is harmless for butterflies and bees. What about the monarch butterfly caterpillar? The monarchs caterpillars eat the milkweed leafs, and have lots of aphids. Will organocide harm the caterpillars? Thank you

    • Organocide is not harmful to caterpillars. It works on small soft bodied insects.

  10. Can Organocide 3 in 1 garden spray be applied to Red Apple using a hose-end
    sprayer?

    I have a large area and it’s on a pretty steep slope.

    Thanks

    • Of course you can use any sprayer you like that puts out a fine mist. Spray until runoff, early morning or early evening hours.

  11. Instead of going to a nearby nursery (of which there are very few in my area) and obtaining their marked up Dormancy oil spray, i found your 3 in ! product at the local Walmart. It doesn’t really say much about its use as a dormant oil spray but i bought it as such for spraying on my peach, nectarine, apricot and 2 apple trees. Will this product suffocate over-wintering critters on such trees?

    • We wrote a blog about the use of Organocide as a Dormant Oil:
      • It’s the most important spray to be applied to fruit trees! Remember that some soft-bodied insects are hiding in crevices and cracks in the bark so make thorough coverage when spraying. The spray of Organocide kills most overwintering adults and eggs, and thus slows seasonal build-ups. Apply at a rate of 4 oz per gallon before the buds swell or before new growth starts in the spring. If applied after growth starts, the fresh new tissue can be damaged. Apply when temperatures are above freezing and when the weather forecast calls for nonfreezing temperatures for at least 24 hours after application.

  12. Can this be used to treat apple scab?

    • Dear Stephanie,

      We want to thank you for writing to us and for viewing our website. We appreciate your questions and feedback.

      For Apple scab you would want to use our product called Organocide Plant Doctor Systemic Fungicide.
      The rate is 3 to 4 tsp. per gallon of water.
      First application at open cluster. Last application at fifth cover or fruit at 2″ to 2½” diameter. Total of 10 applications at 10
      to 12 day intervals. When conditions are conducive to a black spot outbreak, apply ORGANOCIDE PLANT DOCTOR™
      immediately. Note: After 4 or 5 consecutive applications some yellowing of extension growth may be observed. If yellowing occurs use another fungicide until yellowing of leaves disappears.

  13. Hello, Thank you for making such a good and safe product. I use it often and am happy to report that my ladybugs are still alive and doing well on my plants. I am being invaded by Argentine Ants. When I spray with Organocide they seem to diminish for 1-2 days then return with a vengeance. I am sure that are re-introducing aphids. 1. Does Organocide kill ants ? 2. if not, is there something safe – organic I can mix with Organocide to kill the ants. Thank you for this product.

  14. We sprayed our vegetables garden yesterday…it is safe to harvest and eat?

    • We want to thank you for writing to us and for viewing our website. We appreciate your questions and feedback.

      There is no re-entry time after application and plants can be harvested right after spray.
      Organocide is made up of all food-grade oils.

  15. I HAVE BEEN USING YOUR PRODUCT AS WELL AS FERTI-LOME TRIPLE ACTION PLUS II PER INSTRUCTION FROM ONE OF OUR LOCAL NURSERIES ON A PURPLE PASSION PLANT. I HAVE HAD THIS PLANT FOR MANY YEARS WITH NO PROBLEMS. I HAVE NOW BEEN GETTING WHITE AND GREEN BUGS ON THIS PLANT ONLY. I SPRAY IT ALMOST MONTHLY ROTATING INSECTICIDE, WHEN I THINK THE BUGS ARE GONE THEY REAPPEAR. WHAT MIGHT I BE DOING WRONG. IS THERE A DIFFERENT PRODUCT THAT WOULD WORK BETTER FOR THIS PARTICULAR PLANT?

    • We will need to know what insects you are trying to control.
      Organocide 3-in-1 Garden Spray kills the eggs, larvae, nymphs and adult stages of over 25 soft bodied insects including (but not limited to) aphids, chinch bugs, citrus rust mites, flea egg & larvae, fuchsia mites, fungus gnats, hemlock wooly adelgid, leaf-rollers, mealy bugs, psyllids, scale, spider mites, thrips, and whiteflies .

  16. I have some plants that seem sensitive to some treatments. I have not tried organocide on them. One in particular is the Cranberry Hibiscus and another is the Roselle. The Cranberry Hibiscus leaves are edible with a cranberry flavor good for salads and some dishes. My problem is that they are being destroyed by mealybugs and aphids. I removed them with an alcohol solution but the plants continue to deteriorate. Is it possible that there is something in the soil as well? Will a drench of organocide help and can it be applied to the aphids on the buds and flowers? Will it affect the flavor of the leaves? Thanks for any solutions.

    • As indicated on Organocide 3-in-1 label the product has an unusually high degree of safety to most plants. But since you have some plants that seem sensitive to some other treatments, we highly recommend to test first on a small area of foliage to determine plant safety. The test will also let you know if there is a change on the flavor of the Cranberry Hibiscus and Roselle leaves. Regarding your problem with mealybugs and aphids, we recommend to use a rate of 3 fl. oz. of Organocide 3-in-1 per gallon of water. The alcohol solution you are using will control in some degree the aphids and mealybugs by dehydration, but it also will cause the same effect over your plants. Yes it is possible that there are also some other insects in the soil as well. A drench of Organocide at the same rate will help to control root aphids and other soft bodied insects. It can be applied to control the aphids on the buds and flowers, but be careful to spray early in the morning or late in the afternoon and when temperature is below 90F. We are sure about the efficacy of Organocide 3-in-1 on controlling aphids and mealybugs, but we want to be sure about your other inquires. Then, please test the Organocide 3-in-1 first to be sure about plant safety and flavor change. Give two days after spray to observe if there is some leaves damage and then cut some leaves to check the flavor.

      • I did as instructed and used Organocide on a test plant, first. I sprayed and also did a soil drench. I am happy to say that it appears to have removed all signs of aphids and mealybugs and the test plant perked up considerably. It has been a month and it still looks good. The leaf I munched on after a couple of weeks seemed to be as flavorful as before.

        I also used it on some other plants including the citrus. I pinched some of the canals where I saw leaf minors in the leaves and sprayed the small tree twice. I did not see the leaf minors after that but know I will have to continue to keep my eyes on it.

        I also appreciate that Organocide is safe with bees when applied properly.

        Thanks for the help!

  17. If I use this early morning, how long do I have to wait before I can fertilize? Can I mix it with water soluble fertilizer? I use a few drops of dish soap with my fertilizer to help it better adhere. Can I use dish soap with this as well?

    • Celeste,

      Organocide 3-in-1 Garden Spray can be tank mixed with soluble fertilizers, but it’s dependent on the soluble fertilizer type.
      First mix the soluble fertilizer and check the pH: if the pH is lower than 5 do NOT mix it; if the pH is 5 or above then it CAN be mixed.
      Always do a small test before moving to a larger quantity.

      If you are not tank mixing then a foliar fertilizer can be applied two days after using Organocide 3-in-1.

      You may use 1 tablespoon of Ivory dish soap per gallon of water with Organocide 3-in-1 and it will provide a a better spread and penetration.

  18. Can this product be used to spray on my Magnolias?

    • Yes, you can use on magnolias and also in organic gardening on vegetables, fruits, nuts, vine crops, herbs, ornamentals, greenhouse crops, turfgrass, landscape plants, bulbs, flowers and field crops.

  19. I am a first time Greenhouse gardener. (12′ x 24′). Everything is growing beautifully! About a month ago I found bugs in the plants in soil containers of carrots and potatoes. Soon they spread to some of the plants in my 3 towers and some of the 8 hydroponic Grow Bins. I found the only quart container of Organocide 3-in-1 Garden Spray at Home Depot and have been using it. Bugs are not gone, but they will be! Also your Website was helpful with the recipe for cleaning the veggies. I am much relieved and totally greatful for your help.

    • Thanks for using our products and for your referrals!

  20. I have had good results with your 3in1; however its residuals in my pump-up sprayer have reduced its flow rate considerably. Rinsing with water does not relieve this condition. Is warm soap and water an effective way to clean it out, or do you have a better recommendation?

    • First of all we would like to thank you for purchasing Organocide 3-in-1 Spray. We’re happy that you’re finding it helpful. We’ve found over the years that the best way to clean out your spray nozzle is with a citrus based cleanser like “Zep Heavy Duty Citrus Degreaser” which is available at most Home Depot stores. If you use some of that (or something similar) with hot water, it should clear it out just fine without causing any contamination that you’ll need to worry about in the future. Thanks for your question. Let us know if you have any other questions or concerns.

  21. I’ve used this off and on all summer this year 2015. I recently moved and was finally able to have a vegetable garden and lots of indoor and outside plants. And I was visited by all sorts of insects, spider mites, mealy bugs, fungus gnats, aphids and most recently thrips! They all took turns visiting, never had more than one type of insect at a time, but no matter what came to munch my plants, organocide 3 in 1 got the best of all them! Once dried the smell goes away, and it’s really not that terrible to begin with. I love that it is made with all food grade oils so if I get a little bit on my skin or clothes I know I’m not poisoning myself! As I said I used it in my veggie garden and all kinds of house plants, from spider plants to succulents and cacti and they were all fine with it. Love this product and will recommend to anyone with hungry insects munching their plants!

  22. will this product kill squash bugs?

    • Organocide 3in1 Garden spray can be effective on the squash bug if used prior to the insect reaching the adult stage. Squash bugs populate at the base of plants during warm weather therefore you should clear the base of the plant from debris prior to applying. For best results, spray during the coolest time of the day (early morning or late evening) and allow 3-4 hours for product to dry. Do not apply when temperatures exceed 95°F. A single application is normally enough for control. For normal maintenance, spray once per month or as needed to spot treat areas. For severe problems, make two applications 5 days apart. Reapply in 7 days if problem persists. If you have any questions please feel free to contact us again.

  23. Is Organocide 3-in-1 the same as “Plant Doctor” except Organocide does 2 more things?

    • Good Morning Harry,
      The Organocide 3in1 Garden Spray and Plant Doctor are greatly different. In fact the only similarity between the two is that they both cure powdery mildew.

      Organocide 3in1 Garden Spray is also an OMRI certified product made of oils. This topical foliage product smothers insects and controls few types of fungus. It does not harm beneficial insects such as Bees and Butterflies. Its main goal is to control small soft bodied insects and larvae while being environmentally friendly.

      Plant Doctor is an EPA regulated product made from phosphites. The Plant Doctor treats pathogenic fungus through a systemic procedure and does not work on any type of insect. When a plant absorbs the readily available phosphite it triggers the plants defense mechanisms allowing it to defend its self from harm; similar to how a vaccine works on a human.

      Be very careful when selecting which product to use in your garden to control any issues you may have. If you are ever in doubt you may always contact us in the office at (772)286-5581 for further technical assistance.

      Thank You for supporting our products!
