A colleague at Ohio State University (sorry, I mean The Ohio State University) shared a recent series of extension publications they put together related to specialty crop injury from the auxininic herbicides dicamba and 2,4-D.
Dicamba and 2,4-D Fact Sheet Series
Admittedly (and thankfully!) we do not have the same challenges with these herbicides in California specialty crops as they do in the Midwest where small grains, corn, and more recently dicamba- or 2,4-D-tolerant soybeans are grown on millions of acres. However, I thought these fact sheets were well done and provide relevant information with regard to herbicide drift and investigating and documenting herbicide.../h1>
In order to prevent herbicide damage in young trees, especially from postemergence herbicide, standard pomological practice is to apply white latex paint to the bottom 2 to 3 feet of trunk of newly planted trees, before applying herbicides. While this may provide some level of protection, research to support this practice is lacking. In order to assess the efficacy of white latex paint in mitigating herbicide damage, a field experiment was conducted in Arbuckle, CA to evaluate the impacts of latex paint on herbicide injury in young almond trees.

Although the main objective of herbicide use in avocado orchards (and all crops) is to manage weed populations, sometimes unintentional injury of the crop itself can occur when herbicides are incorrectly applied. Herbicide injury in avocado can reduce yield, decrease fruit, reduce plant vigor, increase susceptibility to diseases and pests, and sometimes result in plant death. Common situations resulting in injury include spray drift, tank contamination, application of the...
UCIPM Press Release:
New UC IPM photo repository shows plant damage from herbicides
January 9, 2015 – Davis, California
Identifying nontarget crop and ornamental plant damage from herbicides has become much easier, with the launch of a new online photo repository by the Statewide IPM Program, University of California Division of Agriculture and Natural Resources.
Dr. Kassim Al-Khatib, weed science professor at UC Davis and director of the UC Statewide Integrated Pest Management Program (UC IPM), has gathered nearly a thousand...
