DIVERSIFYING WEED CONTROL TOOLS FOR SUSTAINABLE AND ECONOMIC PRODUCTION OF EDIBLE SPECIALTY CROPS

Michigan is the second most diverse state in the agriculture sector followed by California. More than 30 different types of fruit and vegetables are produced here in Michigan. Weed control is a continuous challenge for production of these specialty crops.More research is required to improve current methods and to develop economic, effective, and environment-friendly weed control strategies by combining both chemical and non-chemical practices. Therefore, the overall aim of this project is to provide research based integrated weed management (IWM) solutions to the edible specialty crop growers which will lead to effective weed control and ultimately good quality crops with higher yields and profitability.OBJECTIVES:1. Screen for herbicide resistance to key weeds, including pigweeds, horseweed, large crabgrass, and common ragweed in fruit and vegetable production systems2. Assess the spread of purple amaranth in Michigan, develop extension material for awareness, and design management strategies for its control.3. Evaluate the best fit for electricity-based weed control in IWM systems for carrot, squash, and pickling cucumber4. Evaluate a vision-guided, precision sprayer with respect to weed control efficacy and crop safety as compared to traditional broadcast applications5. Obtain phytotoxicity, efficacy, and residue data to support potential new uses and registrations of herbicides on fruit and vegetable crops (IR-4 Project)
