The 346-page comprehensive pest management guide includes new herbicides for field crops and updated herbicide, fungicide, and insecticide efficacy tables. It also includes updated information on how to control resistant weeds, especially Palmer amaranth.
"If I had RUP dicamba training in 2018, do I need training in 2019?" The answer to that question, which is "Yes," and other questions about training and new application requirements for the three RUP dicamba products are covered in this FAQ.
Pollen-mediated gene flow at a distance could allow the spread of rare herbicide-resistant alleles and favor the evolution of multiple herbicide-resistant biotypes through the accumulation of different resistant genes in an individual weed or weed population. From the Nebraska Crop Management Conference Proceedings.
Residual herbicides applied at or before planting are critically important to controlling emerged Palmer amaranth in dry bean. Research at the Panhandle REC assessed the efficacy of PRE and pre-plant incorporated (PPI) residual herbicide programs.
Do early season weeds have the same impact as later season flushes? Researchers here report on a 2018 study conducted in dry bean to compare how soon after planting crop yield was impacted by weed presence.
Understanding the critical time for weed removal in corn and soybean would not only ensure effective weed removal and minimize unnecessary weed control inputs, but could potentially help minimize the development of herbicide resistance in weeds.
