Interpretive Summary:

Technical Abstract: Weed control in fruit and nut tree nurseries continues to be a major problem for producers in the Central Valley. Competition from weeds can decrease crop productivity and interfere with field operations (i.e. budding, grafting and pruning) and harvest operations. Most tree nursery production systems currently rely on a combination of preplant soil fumigation, preemergence herbicides, and extensive tillage and hand labor during the growing season for acceptable weed control. Currently, preemergence herbicide choices are limited by number of registered materials and by crop safety concerns. Commonly used products include: oryzalin, trifluralin, pendimethalin, and isoxaben. Herbicides are likely to become a more important part of weed management in tree nurseries as labor and fuel costs rise. Identification of herbicides and herbicide application techniques that provide effective, non-phytotoxic weed control in field nurseries will provide growers with additional options to effectively and economically produce planting materials using an integrated pest management strategy.
