Leucinodes orbonalis, is one of the worst pests that Bangladesh’s farmers face. Farmers spray as many as 150-200 times in a single crop season to try to eradicate it. Fruits are sprayed after harvest to delay larval emergence and deter pests from further attack, in the hope of gaining higher prices on market day. Farmers insist that eggplants cannot be grown without chemicals, but see their profits shrink as they spend as much as one third of crop revenue on pesticides. Farmers report poor results from these chemicals, an alarming sign of increasing pest resistance, so they turn to their peers and pesticide dealers for advice. Dealers recommend stronger poisons, often far in excess of rates required, further perpetuating the problem and reducing future management options. The cycle needs to be broken. But farmers rarely seek assistance from researchers. Extension often has a limited outreach at the field level, and campaigns to reduce pesticides produce fleeting benefits. A study of local knowledge in Bangladesh highlighted many other misuses of pesticides.
