Abstract:

Diflubenzuron (DimilinĀ®; 1-(4 chlorophenyl)-3(2, 6-difluorobenzoyl) -urea), was applied 9–10 times at 0.14 kg AI/ha to all 76 cotton fields in an isolated cotton production area for control of an indigenous low to moderate population of Anthonomus grandis grandis Boheman. Boll weevil population dynamics were recorded in the diflubenzuron treated fields and in a conventionally treated check area. Results indicated >90% control of reproduction. The F3 boll weevil population in the diflubenzuron treated area was no higher than the initial overwintered population, but the population increased 12X where conventional chemicals were used.
