u can foliar spray/ or water with neem oil.



Formulations made of Neem oil also find wide usage as a bio-pesticide for organic farming, as it repels a wide variety of pests including the mealy bug, beet armyworm, aphids, the cabbage worm, thrips, whiteflies, mites, fungus gnats, beetles, moth larvae, mushroom flies, leafminers, caterpillers, locust, nematodes and the Japanese beetle. Neem Oil is not known to be harmful to mammals, birds or some beneficial insects such as earthworms, butterflies, honeybees and ladybugs. It can be used as a household pesticide for ant, bedbug, cockroach, housefly, sand fly, snail, termite and mosquitoes both as repellent and larvicide (Puri 1999). Neem oil also controls black spot, powdery mildew, anthracnose and rust (fungus).
For use as a bio-pesticide, pure Neem oil should be diluted at the rate of 1 teaspoon per quart, or 4 teaspoons per gallon of water (metric: 5.2 millilitres per litre) and used as a foliar spray or used as a soil drench at the rate of 1 liter per square meter of soil (3 ounces per square foot). Adding a surfactant greatly enhances its effectiveness. Ordinary liquid dishwashing soap may be used as a surfactant, added at the rate of 1 tablespoon per gallon.

its the soil you are using. Stays too moist and allows knats to thrive and plants to not be at their peak preformance.....My guess it is not FF Ocean Forest soil. Most all issues stoped when changing to that soil. Don't even need nuts in veg. it's a miracle I tell ya...

For many of the things it lists that it gets rid of, it is not a sure fire solution. Thrips are extraordinarily pesky to get rid of, and neem oil will do a decent job, but it never seems to rid them completely. And for powdery mildew, I've never heard of using it for that. The spores are everywhere. Even just treating the leaves of the plant with that isn't going to solve the problem.

Fungus gnat larvae come in almost ALL soil. The ONLY sure fire way to remove them is microwaving your soil before you plant. One way to keep the gnat count down is mosquito dunks. Just set the dunk in the water your going to use overnight and water! This won't get rid of them, but will help. Either way do it fast because the larvae eat your roots!

I've had fungus gnats on just about every grow,
you MUST let the soil dry out a little and they will soon go, it's the larvae that do the damage by eating the fine root hairs and they soon die without moisture.
Or you can go to a pool shop and buy some diatomaceous earth, (it's used in swimming pool filters)
put about 1/4 inch on top of the soil and it cuts their bodies to shreds when they try to penetrate it. :joint:
