This chem killed a bad infestation last year , active component is cypermethrin which is a synthetic pyrethrum , used as a soil drench with no harm to the plants , not approved for this use and unexpectedly effective.
The typical half-life of cypermethrin in the soil is 30days.
The average half-life of cypermethrin on foliage is 5
days , fast enougth to use till early flower.
As an analog of a natural compound generally recognised as safe , i dont see much risk in its use.
