Growers who decide to terminate their wheat crop because of poor stands or weather-related damage need to consider the persistence of herbicides applied to the wheat. Many wheat herbicides have fairly long crop rotation restrictions.
Drought and late freezes have impacted wheat stands in many areas across Kansas this year. As a results, weeds are showing up and taking advantage of thin wheat stands. What are the best options for weed control at this point in the season?
Cover crop response to herbicides will be influenced by a number of factors, including biological and biochemical characteristics of the plant, chemical characteristics of the herbicide, and weather conditions since herbicide application.
Growers considering re-cropping wheat fields need to consider the herbicide program that was used in the wheat crop. Many wheat herbicides have fairly long crop rotation restrictions. This article lists the minimum rotation intervals for certain summer crops following selected wheat herbicides.
Recent developments associated with market opportunities for winter canola may lead to increased planting in the fall of 2024 and beyond. As you make seeding plans, consider the herbicides you use or have used in your fall and summer crops. Some herbicides may have rotation restrictions for canola.
Herbicides require time to break down in the soil. When drought, hail, or other situations change crop rotation plans, it can result in concern about herbicide injury due to inadequate time for a potentially harmful herbicide to break down. A bioassay is a simple test to determine if herbicide residues are present to potentially harm a newly emerged crop.
As fall progresses, some producers consider seeding winter cover crops in fields currently planted to corn. A number of factors, including the plant's biological and biochemical characteristics, the herbicide's chemical characteristics, and weather conditions since herbicide application, will influence the cover crop's response to herbicides.
