The Pest Management Regulatory Agency recently announced a label expansion for Vayantis seed treatment for the control of seed rot and pre-emergence damping-off caused by Pythium spp. on a wide range of crops, including ginseng, culinary herbs listed within any crop group (Crop Group 25, CG3 (chives), and CG4 (dill, cilantro, parsley)), spices (Crop Group 26), and many specialty vegetables. Consult the label for the full list of crops covered. This registration only covers Vayantis alone (picarbutrazox) and not other formulations with a mix of active ingredients (e.g., Vayantis IV). This label expansion was secured by the registrant, Syngenta Canada Inc.
Syngenta added edible podded and succulent shelled beans and peas (Crop Subgroup 6A and 6B), root vegetables except potato (Crop Subgroups 1A and 1D), bulb vegetables (Crop Group 3-07), leafy vegetables except watercress (Crop Group 4-13), fruiting vegetables (Crop Group 8-09), cucurbit vegetables (Crop Group 9), herbs (Crop Group 25), spices (Crop Group 26), stalk, stem and leaf petioles (Crop Group 22) as well as Brassica head and stem vegetables (Crop Group 5-13) to the label.
Vayantis seed treatment can be applied by commercial seed treaters or at the farm using seed treatment equipment that accurately meters, mixes, and applies a flowable seed treatment. The equipment must provide uniform coverage of Vayantis seed treatment on the seed. Uneven or incomplete seed coverage may not give the desired level of disease control.
