Avaunt® eVo insect control from FMC has obtained a supplemental label for use on tree nuts to control codling moth, navel orangeworm (NOW) and peach twig borer in California. Crops on the label include almonds, pistachios and walnuts, both black and English.

This tool delivers rapid activity with residual control of Lepidoptera as well as a new insecticide mode of action for tree nuts. Built on the active ingredient indoxacarb, an IRAC Group 22A insecticide, Avaunt® eVo insect control utilizes a unique mode of action previously not available for tree nut growers.

As a Group 22A insecticide, Avaunt® eVo insect control has little to no impact on beneficial insects, does not flare mites and has no cross-resistance to other insecticides. These components make Avaunt® eVo insect control an excellent fit in integrated pest management programs and rotational tool with solutions like Altacor® insect control powered by Rynaxypyr® active on almonds.

“The introduction of Avaunt® eVo insect control for California tree nuts is another step forward in the FMC mission to offer growers more tools to address their challenging pest spectrum, reduce selection pressure on existing chemistry and enhance the growing environment,” said Issa Qandah, technical service manager for FMC.

With a distinct pest control range, Avaunt® eVo insect control, depending on the pest, can be used during both larval and adult stages. Specific application recommendations for the three pests noted in the supplemental label are as follows:

Codling Moth

Make initial application at or before peak egg lay for targeted generation. Depending on level of infestation, reapply 14 days later as needed. Use higher rates, MSO/COC blend adjuvant and ground application equipment to achieve thorough coverage.

Navel Orangeworm (NOW)

Use as a mummy spray. Depending on level of pest infestation, use the higher label use rate mixed with MSO/COC blend adjuvant to achieve better performance.

Peach Twig Borer

For spring application to overwintering generation, make application at late dormant, just prior to bud break, to early bloom. For “May spray” applications to the summer generations, make applications at peak moth flight timed at or before peak egg lay. Higher rates in the labeled rate range may be needed for high infestations levels and large, dense foliage trees.

To maximize application coverage, penetration and performance, it is recommended applicators and/or growers use an MSO/COC blend adjuvant when applying Avaunt® eVo insect control.
