Field Crops Webinar Series 3-4-19: Herbicide Efficacy Under Weather Stress - Dr. Erin Burns
From Eric K Anderson on March 6th, 2019
Dr. Erin Burns discusses how weather stress can affect herbicide activity and how to design a program to improve your weed management by planning to buffer weather impacts. Future climate scenarios for the Great Lakes Region predict increasing temperatures and more precipitation in heavy rainfall events, leaving more days during the growing season that have little or no precipitation, polarizing the wet and dry periods. Herbicide efficacy and potential crop damage are highly influenced by weather conditions. For example, herbicides are less effective when weeds are drought-stressed and herbicide movement into the soil is less, reducing weed control. This webinar will focus on herbicide efficacy under various weather stressors (cold, hot, wet, dry conditions) and how to design robust weed management programs to buffer weather impacts and achieve consistent weed control and crop safety.
