Two-Spotted Spider mite in soybeans

Written by Pioneer Sciences Researchers

Two-spotted spider mites (TSM) are being found in many soybean fields across Southwest Norfolk county in Ontario. Reports from Port Rowan and Tillsonburg in late July indicate that this pest is at significant levels in the margins of many soybean fields. If the current hot, dry conditions persist, spider mites are likely to continue to expand across these areas during the next several weeks. This Field Facts explains the life cycle, damage and treatment options for two-spotted spider mites in soybeans.

Delayed Corn Planting Considerations

Written by Pioneer Agronomy Sciences

When rainfall significantly delays field and planting operations, switching to early maturity hybrids may be considered to ensure timely crop maturation. Results indicate that growers should plant full season hybrids until approximately May 26.   Switching to an early maturity hybrid prior to this point most likely will not be beneficial and may result in reduced profitability.

Plantability Testing for Larger Soybean Seed

Written by Pioneer Agronomy Sciences

Soybean seed size is influenced by both genetics and the environment. Under similar growing conditions, varieties will differ from each other in the seed size they produce - small, medium, or large. Genetic effects on size of seed are largely predictable but weather conditions and their effects on seed size are not.  With, appropriate planter adjustments, excellent planting accuracy and stands can be achieved with larger seed.
