Priorities

Category Rank Pest Type Pest Crop Stage Priority
Extension/Outreach 1 All 6- to 12-Inch Shoot Educate government agencies on unfair trade/cultural practices, which result from regulatory burdens.
Extension/Outreach 1 Insects Seed Maturation Provide training on dust management when using various tillage techniques in windy areas.
Extension/Outreach 1 Insects Seed Maturation (Post-Bloom) Develop web site with photos of all insect pests identified in this strategic plan via the California Melon Research Board’s team.
Extension/Outreach 1 Nematodes Seed Maturation Educate growers on the benefit of soil sampling for monitoring with lab analysis of nematode species so that effective control strategies can be implemented.
Extension/Outreach 1 Nematodes Seed Maturation (Post-Bloom) A literature search is needed for information on neem oil (Neemix) as a control option for nematodes.
Extension/Outreach 1 Pathogens Seed Maturation Educate growers on use of thiophanate-methyl (Topsin-M) as a replacement for benomyl (Benlate).
Extension/Outreach 1 Pathogens Seed Maturation (Post-Bloom) Demonstrate post-harvest crop destruction benefits in field production settings (not just in small, research plots) and educate growers on the necessity for the immediate destruction of plant residue (including roots) after crop termination. Many plant pathogens, including those that infect roots, multiply rapidly on crop residue. Foliar application of an herbicide or the use of a flail mower to destroy the crop canopy are, however, counterproductive and actually enhance pathogen reproduction in infected roots.
Extension/Outreach 1 Weeds Seed Maturation Continue training on application techniques for Eptam.
Extension/Outreach 1 Weeds Seed Maturation (Post-Bloom) Educate growers on use of Halosulfuron (Sandea).
Extension/Outreach 1 Wildlife Seed Maturation (Post-Bloom) Provide grower updates on vertebrate pest control options.
Extension/Outreach 2 All 6- to 12-Inch Shoot Regulators and consumer groups must be educated as to how Integrated Pest Management (IPM) practices are used in melon production and how this system optimizes food production while it minimizes risks to workers and the environment. This is especially important as it relates to risk assessments for crop production.

Extension/Outreach 3 All 6- to 12-Inch Shoot The general public needs to understand how IPM is used in agriculture and how changes brought about by the FQPA review impacts on the cost of food. The economic side of replacing low-cost pesticides with newer, but much more expensive, materials needs to be considered in the review process.

Extension/Outreach 9 All 6- to 12-Inch Shoot Finally, the public should be reminded through effective media (e.g., “Buy California”, “Five a Day” programs) that the consumption of fresh fruits and vegetables, particularly melons, contributes to a nutritious diet and healthy lifestyle.
Regulatory 1 All 6- to 12-Inch Shoot Harmonization between Cal-EPA and US-EPA should be encouraged to facilitate and hasten the registration of reduced risk products. It now appears that concurrent registrations of pesticide labels on a federal and state level have been lost. Budget cuts at the state level at the California Department of Pesticide Regulation (CDPR) would force a longer waiting period for state reviews. Any delay in getting the federal pesticide label approved for use in California puts our growers at a disadvantage when materials get approved first in other states. The registration process for new chemicals should be looked upon as a means to add alternatives for use in rotation with older products that need to be retained for pesticide resistance management.
