Article Synopsis
- The Colorado potato beetle (CPB) is a significant pest for potatoes and related vegetables, causing severe damage to crops by feeding on leaves.
- Traditional insecticides have become ineffective due to overuse of the same chemical classes, creating a need for alternative pest control methods.
- Ledprona is a novel biopesticide that uses double-stranded RNA to effectively target CPB, showing high mortality rates in lab tests and performing comparably to established insecticides in greenhouse trials, while awaiting EPA registration.
Common ragweed emerges early in the season in Nebraska, USA and is competitive with soybean; therefore, preplant herbicides are important for effective control. Glyphosate has been used as a preplant control option; however, confirmation of glyphosate-resistant (GR) common ragweed in Nebraska necessitates evaluating other herbicide options. The objectives of this study were to (1) evaluate the efficacy of preplant (PP) herbicides followed by (fb) glufosinate alone or in tank-mixture with imazethapyr, acetochlor, or -metolachlor applied post-emergence (POST) for control of GR common ragweed in glufosinate-resistant soybean; (2) their effect on common ragweed density, biomass, and soybean yield; and (3) the partial economics of herbicide programs.
