Control of Mites in Industrial Hemp Open Field Study

PROJECT TITLE: Control of mites in Industrial Hemp Open Field Study JUSTIFICATION AND OBJECTIVES: IR-4 received a request to identify efficacious insecticides to control mites (Acari:Chelicerata) on hemp plants (≤0.3% THC) and assess the crop safety deriving from the use of the proposed insecticides. As it stands today, there is a limited number of effective management tools for the control of mites on this plant, which poses the need to identify efficacious acaricides among products that are or are not currently available on the market. The objectives of this study are to: 1. Assess the efficacy of a few conventional acaricides that are not registered for use on hemp but are widely used in agriculture for the control of mites (Suffoil-X, Stifle Sc, Fujimite SC); 2. Assess the efficacy of a few biological acaricides that are not registered for use on hemp but are widely used in agriculture for the control of mites (Botanigard ES, MolteX, Abba Ultra); 3. Assess the efficacy of a few minimum risk acaricides exempted from FIFRA registration (TetraCURB, Green Cleaner) 4. Assess the injury caused by the use of these acaricides used at the maximum label rate. Adherence to Good Laboratory Practices (GLPs) is not required for trials conducted under this research plan.
