Melon Crop Losses Workshop July 19, Yuma 1
The Melon Crop Losses Workshop & Whitefly / CYSDV Control Update will be held July 19, 2012, from noon to 3 p.m., at the Yuma Agricultural Center, 6425 W. 8th Street, Yuma Ariz., 85364. Lunch will be provided.
Melon Crop Losses Workshop: Over the past 8 years we have conducted a crop loss survey for melons in Arizona. In order to ensure the quality of responses, we are sponsoring a live meeting for the express purpose of reviewing the process and deriving individual level responses from PCA’s. You are invited to help develop the real world data that makes the resulting estimates so valuable to scientists, other researchers, regulatory personnel, policy makers, and your own industry. These data have been used in defense of chemistry that has been threatened by regulatory action, in support of new regulatory initiatives (e.g., Section 18 and 24c applications), and in support of research and public policy with respect to insecticide usage and insect pest management. In recent years these data have specifically been used to defend or otherwise comment on the use of acephate (e.g., Orthene) and endosulfan in cotton, and to defend the use of diazinon in lettuce and melons. Data in cotton have also been used in support of Section 18 requests for pyriproxyfen (Knack) and buprofezin (Applaud, Courier). Furthermore, these data will be useful in assessing the impact of new classes of insecticide chemistries on the melon industry. These data play a unique role in the understanding of insect losses and the role of insecticides in cantaloupe and watermelon production. Because the information is by pest insect and based on your understanding of the intended targets of the insecticides used, it provides a unique source of information on losses due to individual pest insects and the specific costs to control them. Furthermore, these are the only data provided directly for spring melon production.
Research Update: Whiteflies and CYSDV continue to cause serious economic problems on fall melons. In response to this problem, a considerable amount of research has been directed towards finding cost-effective solutions to management of both whitefly adults and the subsequent transmission of the virus. New information on management is particularly important now since endosulfan will not be available to melon growers this next fall. This update will provide new information on a number of insecticide alternatives that have been evaluated as replacements for endosulfan for adult whitefly control. In addition, virus incidence on spring and fall melons over the past 5 years will be discussed.
