1 pyrethroid (e.g. Asana, Warrior) |
2 OP = organophosphate (e.g. Diazinon, Guthion, Imidan) |
3 IGR = insect growth regulator (Dimilin, Intrepid, Esteem, Seize) |
4 Bt = Bacillus thuringensis |
5 Inseason use of some IGRs (e.g., methoxyfenozide-Intrepid) has a reproductive impact on parasites and lacewings |
6 carbamate (e.g. Sevin). |
7 neonicotinoids (Actara, Provado) |
