FUNGICIDE PERFORMANCE EXPERIMENTS are important for California strawberry growers. In this experiment we are evaluating organic products for their ability to c...ontrol Macrophomina crown rot. Strawberry Center undergraduate students, Mason Wong (Agricultural and Environmental Plant Sciences), Kaleb Roberson (Agricultural Business), Samantha Farao (Agricultural and Environmental Plant Sciences) organize plants in 6 lines for drip irrigation in one of the Strawberry Center’s hoop house tunnels. By late summer we should know the performance of these products and be able to advise the manufacturer of its efficacy. See more
