It’s called Voliam Xpress and has been recently registered by Syngenta for use on all types of corn. Voliam Express is a pre-mix of two powerful insecticides with proven effectiveness against European corn borer, corn earworm, and western bean cutworm.
The attractive aspect of this new insecticide is that it offers dual control by both contact action as well as by ingestion. In addition it is effective on egg, larva, and moth stages of lepidopteran insects.
Voliam Xpress provides quick knockdown plus long-lasting residual using a mixture of the popular Group 3 pyrethroid insecticide lambda-cyhalothrin (e.g. Matador) with the Group 28 insecticide chlorantraniliprole (e.g. Coragen). In addition to promising better control using two quite different actives, it should offer a sound resistance management strategy. Still, it’s a good idea to rotate insecticides to ensure resistance doesn’t get a foothold in your crop.
Growers will also like the fact that Voliam Xpress is rainfast as soon as it dries and since it has translaminar activity (i.e. locally systemic), some of what your spray will move into and throughout the leaf surface to provide residual activity. Sweet corn growers will also appreciate the one day pre-harvest interval.
Although Voliam Xpress has some systemic activity, good spray coverage will still deliver the best results. And since the pyrethroid component in the product is affected by higher temperatures, avoid spraying this product during the heat of the day.
This is definitely a product that looks pretty interesting on paper. Corn growers should ask their local dealer about it before those nasty insects make an appearance.
