Identifying and Addressing Soil Structure Challenges   A well-structured soil improves water infiltration, air exchange, rooting, and ultimately crop yield. On the other hand, a cloddy, dense, or compacted soil may result in ponding, nutrient losses, and restricted root systems. Poor soil structure contributes to lower crop yields, especially in seasons that are either too dry […]

Levels of dimethoate effectiveness in two-spotted spider mite populations collected in 31 soybean fields in 2021 and 2022.

Dimethoate Resistant Two-Spotted Spider Mite Populations in Ontario Soybeans Results from bioassays conducted on two-spotted spider mite (TSSM) populations collected in soybean fields across Ontario show the prevalence of dimethoate (Cygon or Lagon) resistance is high in some areas. Through a collaborative project with Dr. Vojislava Grbic, Professor at Western University, Dr. Ian Scott at […]
