Initially, thank you for your advice. That can defeat your pests Without using chemicals

For me there are 600 trees and for my neighbors Which has no need more than 5000 -10000 trees and each tree is large And the height is about 3-story building. Can not catch insects that disturb Therefore need to use chemicals for prevention And get rid of those insects

But whatever your method Is interesting And is acceptable For some Thai farmers that grow organic crops And consumers are happy that they don’t have to eat crops that have pesticide residues as well
