Regional Implementation and Validation of a Smartphone- and Web-Based Scouting and Decision Support System
Location: Subtropical Plant Pathology Research
Project Number: 6618-22000-039-40
General Cooperative Agreement
Start Date: Oct 01, 2012
End Date: Aug 30, 2013
1. Continue to assist with the adaptation of AgScouter in Florida and assist in the development of the chemical management module for Florida production.
2. 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 and the thrips-vectored virus Groundnut ringspot virus.
1. Our cooperators have willingly given us access to their scouting reports to measure pest populations through their scouting efforts. The scouting reports have largely been collected by personnel at Glades Crop Care (GCC). For this grant, GCC will continue to foster our relationships with the grower community and help to secure additional scouting records to continue to develop, evaluate, and promote AgScouter. The chemical management module that will be developed as part of this grant is intended to assist growers and scouts in streamlining activities associated with scouting and making management decisions and create a “one-stop shopping” tool for scouts. Data compilation will largely be conducted by personnel at ZedX and information will be pulled from both online (e.g., CDMS.net, greenbook.net, etc.) and printed resources (e.g., University pest management handbooks). Within the database, the relevant information (e.g., crop labeling, labeled rates, restricted entry intervals (REI), post-harvest intervals (PHI), and the EPA registration number) will be extracted from pesticide labels and included as part of the database. Validation of the database for Florida production will be done by personnel at Glades Crop Care and University of Florida because of their extensive knowledge of the agriculture chemicals used in Florida.
2. GCC will also assist in evaluating how use of regional scouting data (disseminated via AgScouter) can impact pest populations, pesticide usage, and factors associated with pesticide inefficiency. This will be done largely through data collection. We plan to document the changes in pest populations and pesticide usage prior to and after implementation of AgScouter on our cooperators farms. In Florida, we currently have a four year database of bi-weekly observations of whitefly densities and TYLCV incidences over a ~20,000 acre area of tomato production region in southwest Florida, encompassing three major producers and 2-3 mid-sized producers, and a three year database of a smaller region in west-central Florida. This database will serve as the baseline of average pest densities of whiteflies and TYLCV severities in Florida. This database also serves as the baseline for thrips and GRSV incidence. Our cooperators, thorough the assistance of GCC, have willingly provided us their scouting reports and we will continue to work directly with them to collect new data through the duration of the study to measure pest populations and pesticide usage after use AgScouter. We will work with GCC to establish new collaborations with watermelon producers in Florida. We have worked with several watermelon growers in the past to scout for the whitefly transmitted viruses SqVYV, CuLCrV, and CYSDV but we do not have the extensive database as we do for TYLCV.
