With the introduction of many new plant growth regulator herbicides, such as dicamba-based, and 2,4D choline products, sprayer system cleanout has become even more critical before spraying resumes this growing season.
Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.
Crop damage could occur if sprayer clean-out is overlooked or not properly conducted. It is critical to always follow the procedure specified on the herbicide or commercial cleaner label to completely remove herbicide residue from the sprayer system.
If the forecast holds true, it looks like it is going to be another year of excessive soil moisture and possible flooding come this spring. The increased level of soil moisture has implications with regards to plant stand establishment as well as root rot and nematode infestations.
With the rise of herbicide-resistant weeds, the use of an adjuvants is also on the rise and may be necessary to help control resistant weeds.
