Last week a local farmer had several hundred acres of crop land sprayed for weed control in preparation for planting no-till soybeans. A farm services company applied a mixture of Round-up and 2,4-D for a quick knock down of all weeds. Unfortunately, the applicator made a huge error in judgement. The herbicides were applied on a day that had both high winds and high temperatures--perfect conditions to maximize spray drift and 2,4-D vaporization.
From past experience with 2,4-D damage, the trees that survive will take at least 3 years to recover. We are currently working with the Kansas Department of Agriculture to document this terrible event.
