Industry Seminar – Grapegrowing
Fungicides are some of the most important tools used by growers to manage disease development in vineyards around the world. Over time, however, continued use of many of these materials often leads to the development of resistance in local or regional populations of organisms, reducing the number of options available to the vineyard manager to control diseases that impact fruit quality, vine health and productivity.
Our three speakers will address how and why disease organisms develop resistance to certain types of fungicides, how to monitor the development of resistant mildew populations before they become problematic, and how growers can develop spray programs that help to sustain the use of effective fungicide materials.
