Pest Management Solutions for Specialty Crops and Specialty Uses
Greetings!

In July, we hosted the first ever Virtual New Technology Session to begin the process of establishing research priorities in the Food Program. In addition, we highlighted the registration of acetamiprid for papaya growers to manage papaya mealybug, and EPA granted residue tolerances for four actives: cyflumetofen, oxathiapiprolin, permethrin and s-metolachlor. For Environmental Horticulture crops, the Thielaviopsis Efficacy summary was updated and the Hydrangea Crop Vignette was posted.

Links to these recent successes for the Food and Environmental Horticulture Programs are below.
