We finished the 2017 season with approximately 2,700 cases under investigation by the various state Departments of Agriculture, and approximately 3.6 million acres of dicamba-injured soybean acres as reported by university weed scientists.

As of June 1, 2018, the reports from university weed scientists and state Department of Agriculture representatives indicate that almost all of the dicamba injury that has occurred in specialty crops, vegetables, and ornamental, fruit, and shade trees.

Only Arkansas, Mississippi, Missouri, Nebraska, and Texas have reported probable injury to soybean (approximately 800 acres) as a result of off-target movement of dicamba, while Tennessee has reported 100 acres of cotton with dicamba injury.

Arkansas, Mississippi, Missouri, Nebraska, Tennessee, and Virginia have each reported injury to various types of trees, ornamental species, garden plants, flowers and berries.

Specialty crops and homeowner cases are usually reported by total number of plants injured rather than by acreage, but it can vary by state and by individual situation.
