Organic growers have a limited number of products they can use for control of insect pests. In this study, the OMRI-listed biological insecticide DiPel* DF was tested at two rates for efficacy in control of diamondback moth larvae in collards. A DiPel* only treatment program provided significant control of pest populations through the season. This study indicates that DiPel* can be an effective stand-alone insecticide for control of Lepidoptera pests.....Read more
Bt field trials produce interesting results for its use in tank mix or rotation with other chemistries. The numbers don’t lie, and the results are dramatic. Marcus Adair is the Senior Field R&D Scientist at Valent BioSciences in Oxford, MS. When he coordinated a series of Bt field trials with cooperators in Florida, California, Texas, and the Carolinas, the objective was to gather hard data on the economic impact of using Bt in tank mix and rotation alongside a variety of other effective chemistries.....Read more

The Bacillus thuringiensis subsp. aizawai insectide XenTari* DF and the synthetic pyrethroid active ingredient bifenthrin were tank mixed and applied to cabbage for control of diamondback moth (Plutella xylostella) larvae. The tank mix combination of low label rates of XenTari* with bifenthrin provided better control than higher rates of either insecticide alone. Low to moderate rates of synthetic pyrethroids and Bt can provide good control with potential additional benefits such as beneficial insect conservation and reduced MRL concerns.....Read more
XenTari* DF biological insecticide was partnered with Coragen* insecticide in a season-long program for control of armyworm pests in tomato. The rotation of these two soft insecticides provided better fruit protection and greater tomato yield, as measured by fruit weight, than a program of Coragen* alone. The XenTari*/Coragen* program also increased the profit per acre compared to the Coragen* only program.....Read more

Organic growers have a limited number of products they can use for control of insect pests. In this study, the OMRI-listed biological insecticide XenTari* DF was tested for efficacy in control of imported cabbage worm and cabbage looper in collards. A XenTari* only program provided significant control of a heavy pest infestation compared to the untreated check. This study indicates that XenTari* can be an effective stand-alone insecticide for control of Lepidoptera pests....Read more
Insecticide chemical residue on crops is a major concern of both government agencies and consumers. XenTari* DF biological insecticide has no residue restrictions associated with its use, making it ideal for application at the end of the season and right before harvest. In this study XenTari* was applied at the end of a rotational program with Coragen*. This program provided excellent control of heavy infestations of cabbage looper and imported cabbage worms on collards.....Read more
