Burndown and Pre-emergence Herbicides for Weed Control in Corn and Soybean

Profitable crop production starts with a weed control program that includes pre-plant and/or pre-emergence herbicides to deliver long-lasting, residual weed control. A spring burndown program in corn and soybean provides effective weed control to prepare for planting and helps to decrease the seedbank during the season.

How Temperature and Rain Can Affect Burndown Herbicides

Finding a good time for burndown herbicide applications has been a little tricky this spring, given the below-normal temperatures the first half of April and intermittent snow and rain, all of which can decrease herbicide efficacy. Checking the forecast can help identify an optimal window for application.

Seeding Practices and Nitrogen Management for Western Nebraska Soybean: What Matters and Why

Continuous corn is the most common irrigated crop sequence in southwest Nebraska. Although rotating to other crops, such as soybeans, can mitigate some production issues of continuous corn and often boost the next year’s corn yield, larger adoption of soybeans has not readily occurred in this area.

Crop Diseases - CPC Proceedings

Corn Disease Update

In 2019, wet weather during the growing season favored the development of numerous corn diseases including Physoderma brown spot, bacterial leaf streak, stalk rot diseases, and ear rot diseases. This update highlights these diseases, the environmental factors that favor their development, and their management.

Soybean Disease Update

Plants under stress due to environmental factors, such as extreme temperature and moisture are more susceptible to disease, and many were under stress due to the unique environmental conditions in 2019.

Wheat Disease Update

In 2019, wet weather during the growing season favored the development of wheat diseases including Fusarium head blight, leaf rust, stripe rust, bacterial streak, and take-all. This update highlights these diseases, the environmental factors that favor their development, and their management.
