2013 Annual Report

1a. Objectives (from AD-416):
1. Adapt the current smartphone and web-based scouting system to California vegetable and grape production. 2. Hold training sessions to teach producers, crop advisors, and scouts how to use the system. 3. Evaluate the utility and benefits of using regional scouting data to base management actions through case studies of the whitefly-transmitted viruses Tomato yellow curl virus and Squash vein yellowing virus in Florida, the mealybug-transmitted Grapevine leafroll-associated viruses in California, and the thrips-vectored viruses Tomato spotted wilt virus and Groundnut ringspot virus in California and Florida.

1b. Approach (from AD-416):
The system will be adapted to California vegetable and grape production by creating digital maps of production fields, and incorporating the extensive database of the insect and disease pests, as well as the management options, into the system. The scouting system has been developed for Florida, but it has not been widely implemented. Training workshops will be held throughout Florida and California and will be led jointly by members from ZedX, locally-based collaborators and grant participants. We will offer individual training sessions for interested growers, grower groups, and scouting companies. 3. Evaluation and validation will be accomplished by comparing management practices prior to and post implementation of the scouting system, as well as surveying grower attitudes towards adopting the new technology.

3. Progress Report:
This research relates to in-house project objective 3: Develop or improve comprehensive integrated disease management strategies. At present, we are working closely with our California collaborator to identify and map production fields in California. We recently hired a post-doctoral research associate (RA) to spearhead the initiative. The RA will contact growers, grower groups, and/or University of California Extension personnel to assist in identification of production fields. Once the maps have been developed they will be sent to our cooperators at ZedX to be included in the AgScouter system. Our cooperators at Glades Crop Care and Red Gator have been regularly collecting and entering data into the AgScouter system using handheld devices so that we may follow-up and verify data integrity and as part of the evaluation of AgScouter. Plans for AgScouter training sessions in both Florida and California have been discussed, but none have been planned.
