Great video, so many people still rocking systemic pesticides like chemilled Avid, or Eagle20. Please do a report on the recent bust of the ''organic'' pesticide Guardian having chemicals put in it!
These guys sold and spammed all over youtube about Guardian being a good organic IPM for mites and PM last season..what a disgrace to the many truly organic farmers who fell for their lie and ruined an entire crop
