Rhizome is our resident pesticide dude. I'll see if I can scare him up for a second opinion, lol.
Stinky , thanks as always for your reply- I will wait until I here more or tomorrow go for it and try the pyrethtrin if I can find it - I have looked several places this AM but will go to Knoxville a larger city this PM and try and find it there
clovisman Reviewed by clovisman on . is pyrethrin insecticide safe to use I have been infested with corn borers- losing a lot of plants well into flower- if i use a pyrethrin wash to cleanse the soil will this hurt the plants or will the plants pull the insecticide into the buds through the root system and i will eventually enhale them- will have to do this today or possibly lose my entire crop need advice Rating: 5
