diatomaceous earth mixed with NEEM oil

Post by dill786 »

hi

can i mix the DE with the neem oil and then use that in water and washing up liquid to spray my plants to keep the fungus gnats at bay or prevent them from moving in? DE is like glass sharp and abrasive so it will kill the gnats, if sprayed all over the plant including underneath and main stem ?



whats the best technique of mixing it? ill be mixing in potsill aswell, that doesnt need to be emulsified does it?



thanks

My only experience with DE was for eradication of Bed bugs several years ago. I would think that you should be fine using it on the soil. I wouldn't try to use it on flowering plants as you'll catch hell trying to remove it from the sticky buds. I would try the oil only on the plants. Just my .2 cents. :toker1:

DE won't work until it's dry. Had to edit that. :winky:

DE once wet wont be of much help.
What has worked for me is using a mosquito dunk in a 5 gallon bucket and letting it sit overnight before using to water my plants. I also put one in my watering can for a double whammy.That in combination with fly strips has gotten rid of my fungus gnat problem. It did take a few weeks to completely get rid of them but I no longer have them in my rooms anymore. I also saw no ill effect to my plants

I've been having a Whitefly problem. Been spraying the room and plants with rubbing alcohol mixed with water and dish detergent. I've been able to knock them down, but not out. Got them off my Datil Chili peppers plants only by removing the Datils from the room. Spraying them especially underneath the leafs and then putting them out side in the sun. Can't do that with the ganja though. They're about half way through flower so I don't want to use anything toxic.

Safer Soap works well for the quick kill (make sure to spray the underside of all leaves).
Wait a few days and then spray with Neem Oil and you should get them.
