The widespread use of dicamba in corn, combined with the high sensitivity of soybeans to this herbicide, results in numerous cases of soybean injury each year. When dicamba injury occurs, whether from spray drift, volatilization, or sprayer contamination, the common question is, How much will yields be affected? As with any source of crop stress, it is impossible to accurately predict yield loss potential from dicamba injury that happens early in the growing season. This article summarizes results of controlled studies to help evaluate situations that occur in the field.
