Barley variety influences fluxapyroxad efficacy by affecting distribution and dissipation of the active ingredient, with plant biomass contributing to these differences. Abstract BACKGROUND Seed‐applied fungicides are used to protect barley seedlings from spot form net blotch, caused by Pyrenophora teres f. maculata, among other diseases.

Evaluating larvicide performance against Culicoides sonorensis in semi‐field conditions
This study evaluated the efficacy of larvicide products against Culicoides sonorensis populations under controlled semi‐field conditions. Larvicide efficacy against C. sonorensis declined over time, in different environmental conditions. In particular, precipitation and habitat disturbance influenced residual performance. Abstract BACKGROUND Culicoides

Spatial concentration gradients of seed‐applied fluxapyroxad within barley create heterogeneous exposure environments, driving differential suppression of succinate dehydrogenase inhibitor‐sensitive Pyrenophora teres f. maculata isolates and enrichment of reduced‐sensitive genotypes, thereby shaping within‐host fungicide resistance selection dynamics ...

Early soybean planting in cool, wet soils slows emergence and results in about half the insecticide and fungicide concentrations at vegetative emergence compared with standard planting, where faster emergence maintains roughly double the pesticide concentrations, yet pesticide persistence remains similar across both planting dates.

QuEChERS is a simple and efficient extraction method, widely used in the pesticide of residue detection. The purpose of this paper was to compare the extraction methods of pesticides between the improved QuEChERS method and the GB/T 24691—2009 (fruit and

Aerial applications deposited more insecticide on tassels than on ear level (36.4% vs. 19.8%). Across both application methods, chlorantraniliprole minimized ear injury, while bifenthrin provided moderate control. Effective management of S. albicosta requires delivering sufficient insecticide concentration to the target site and achieving adequate ...
