Bayer Corporation received registration for Leverage 2.7 Suspension Emulsion Insecticide last summer to control multiple mid- and late-season pests. Cooperators found the new insecticide lived up to expectations.

"Leverage is a good fit for control of late-season aphids, bollworms and plant bugs, and for when bollworm and aphid populations are building," said Dr. Charles Allen, University of Arkansas Extension entomologist.

"If growers are concerned about plant bug resistance, Leverage also works great after a stand-alone pyrethroid treatment," he added.

Leverage provides mid- to late-season control of multiple pests, including worms, weevils, aphids, thrips and plant bugs, along with other secondary pests—without the hassles of tank mixing. The insecticide combines two proven modes of action for greater efficacy, a broader control spectrum and reduced likelihood of resistance.

Leverage controls insects in two ways. First, it affects the nerve synapses of insects through direct control or ingestion and is especially effective against sucking insect pests. Second, it acts as a nerve cell membrane disrupter to control chewing and various sucking pests, including bollworm, plant bug, stinkbug and boll weevil.

Leverage provides excellent control in both conventional and Bt cotton, according to Jimmy Johnson, cotton product manager for Bayer.

"Multiple pest control makes Leverage the ideal foundation for an insect management program in conventional cotton," Johnson said. "It complements a Bt cotton program by controlling bollworm escapes and other pests that Bt misses.
