Lygus bugs damage cotton crops in the San Joaquin Valley by feeding on developing squares. They are particularly difficult to manage since they move about freely and have unpredictable feeding habits. Four different materials and combinations were applied to cotton to evaluate their efficacy for lygus bug control. Monitoring was accomplished by sweeping and counting upper nodes. Both non-registered materials effectively controlled lygus bugs. A single application reduced pests numbers for 6 – 8 weeks and yet was gentle on beneficial and the environment.
