Thomas Turini conducted experiments over three years to help producers control tomato spotted wilt on processing tomatoes. Tomato spotted wilt can cause substantial yield loss. It is transmitted by an insect that is difficult to control and it is likely that one tactic alone will not effectively control this disease. Information regarding relative susceptibility of varieties to this disease and in-field management of the insect that transmits this virus (thrips) has been generated and provided to clientele. The influence of control programs on the incidence of the virus in the field as well as analysis of yield and quality in processing tomatoes over two years of field trials on this subject have also been shared. This information has been used by consultants to develop and evaluate their management programs resulting in fewer applications of insecticides that are ineffective against the thrips target. In addition, they now can consider relative susceptibility of processing tomato varieties when making thrips management program decisions.

Tomato virus disease concerns at UC West Side Extension Center
Among the obvious concerns that vegetable crop growers face this season is the potential of a second consecutive year for curly top disease in tomatoes. In 2013, some fields in Fresno, Kings and Kern Counties were severely impacted by this beet leafhopper-transmitted virus disease. In some fields, the majority of the plants were lost early in the season and the fields were replanted, while in other cases, the impact was seen too late to replant and the fields may have been shredded or farmed to harvest, frequently, with disappointing yields.
