Soil Temperature for Planting Spring Crops

Soil temperature is an important consideration for deciding when to begin planting spring crops. If producers in South Dakota would like a quick reference for soil temperatures in their area, the SD Mesonet network measures soil temperature at several weather stations throughout the state.

Low Temperature Damage to Corn and Soybean

Temperatures are forecast to reach 32°F or lower in large areas of South Dakota for several nights beginning on May 7, 2020. While a relatively low percentage of planted crops are likely to be emerged at this point in time, producers may still want to evaluate individual fields for crop damage.

Powdery Mildew: A Disease Concern in Field Peas

Producers of field peas may need to scout for powdery mildew this year. Powdery mildew is a late-season fungal disease that can impact peas if weather conditions are conducive. However, this disease can also occur in early planted fields in South Dakota under the right environmental conditions and when the crop canopy is heavy.

Spot Treatment Options for State Noxious Plants

When controlling grassland weeds, the mindset of row crop weed control may be put into practice too often. In most cases, broadcast control of weeds in grasslands is rarely necessary. Most often, spot treatment can be used more effectively to manage the noxious and invading weeds.

Current Weather Conditions Are Conducive White Mold Development in Soybeans

Frequent rains and overcast conditions continue to occur in South Dakota’s main soybean growing counties. These conditions favor white mold development. In some of these counties, soybean is already at R1, which is also the best timing for fungicide application targeting white mold control.
