Suppression of Emerging, Early-Season Boll weevils Using Integrated Control123

In 1968 and 1969, field experiments were conducted at Florence, South Carolina, against populations of emerging overwintered Anthonomus grandis Boheman. In 1968, complete suppression was not achieved with an integrated control program consisting of foliar sprays of toxaphene + DDT + methyl parathion, plus in-furrow and sidedress applications of aldicarb, but the population of overwintered boll weevils was reduced 57% below that resulting from foliar treatment alone. In 1969, one integrated program consisting of foliar sprays of toxaphene + DDT + methyl parathion plus the in-furrow and sidedress applications of aldicarb, and another consisting of the same treatments plus boll weevil pheromone traps, suppressed the population of emerging over wintered boll weevils.
