AI Technical Summary

Technical Problem

Current methods for controlling pests on soybean plants, particularly Bt-soybeans, are inadequate in effectively managing insecticidal and nematicidal pests, and there is a need for improved methods that do not harm non-target organisms like the Monarch butterfly.

Method used

Treating Bt-soybean plants with ryanodine receptor modulators such as Chlorantraniloprole, Cyantraniliprole, and Flubendiamide, which are combined with Bt toxins like Cry 1 Ac and Cry IF, to enhance pest control and nematode management, while ensuring minimal impact on non-target species.

Benefits of technology

The treatment significantly reduces pest mortality and nematode activity, improving soybean plant health and yield with a synergistic effect that provides comprehensive pest control and resistance against various pests and nematodes, while posing a negligible threat to Monarch butterflies.

Abstract

Method for controlling pests by treating Bt-soybean plants with at least one ryanodine receptor modulator selected from the group consisting of chlorantraniloprole (Rynaxypyr), cyantraniliprole (Cyazypyr), flubendiamide and diamide tetrazole compounds (l-4a) and (l-4-b). Synergistic composition comprising a Bt toxin encoded by a specific nucleotide sequence and the ryanodine receptor modulator. A Bt-soybean plant with at least 0.00001g of the ryanodine receptor modulator attached to it.
