There is some biology to keep in mind if you want to use herbicide in the summer months

Recent high temperatures are impacting herbicides.

A Weed Specialist at Kansas State University, Sarah Lancaster, shares the biology to keep in mind when considering herbicide use in the summer months.
She says that applying in the early morning allows plants to recover from heat stress before application. That allows herbicides to reach active sites, killing weeds effectively.

Also, consider using maximum labeled rates to help more spray solutions get into the plant. Postpone application of contact herbicides in temperatures over 90 degrees and avoid using Group 4 products such as dicamba in similar conditions to limit evaporation.
