Challenging weather conditions in the spring may have resulted in rapidly growing Palmer amaranth in grain sorghum fields. Post-emergence herbicide options in grain sorghum are limited, with the available choices most effective when the weeds are small. This article discusses the pros and cons of key herbicides that can provide control.
Applying certain herbicides when air temperatures are high could reduce their effectiveness on controlling Palmer amaranth. Research conducted at K-State described two key changes about how Palmer amaranth responds to applications of mesotrione (Callisto) under high temperatures.
The most predictable aspect of the weather in Kansas is that it is unpredictable. We can learn a lot from looking at how temperature and precipitation measurements compare to the 30-year normal. This article examines 20 Mesonet station all across Kansas and how this first half of 2022 compares to the last 30 years.
