Dicamba Injury Reports, 2018: What a Difference a Year Makes

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.

As of June 1, approximately 200 tomato plants, 150 ornamental trees, 30 fruit trees, 250 vegetable plants, and 150 berry species were reported with probable dicamba injury in these 6 states, along with approximately 50 acres of hardwood/shade trees.

The states of Alabama, Florida, Georgia, Illinois, Iowa, Kansas, Kentucky, Louisiana, Michigan, North Carolina, North Dakota, Ohio, Pennsylvania, and South Dakota have not reported any incidents of off-target movement of dicamba so far.
