I treated tomato plants infected with white fly with a plant extract gave very high effectiveness and I want to measure whether there are residues of fruit or not ?
If your plant extract is safe and not contains known toxic substanses you dont need to worry or interest about residues
Good job I wish to get a clear answer bro...
I was shared your question among my colleagues to find which you search about dear
Great information, thank you very much, but I have a question. Can I adopt the plant extract as an insecticide?
