Activity of Fungicides on Grape Diseases and Impact on Honeybees

See the product label or crop calendars for registered uses. Use fungicides only for diseases listed on the product label for the crop. The information provided in this table is based on information from other areas. It is intended to assist the grower in choosing the best fungicide for control of pests listed on the product label, while managing resistance and avoiding unnecessary sprays for non-target pests. Efficacy can be affected by rate of the product.

M = Multi-site fungicides. BM = Biological with multiple modes of action. NC = Not classified by FRAC, or group not indicated on product label. P = Plant defence inducer. U = unknown mode of action 1 Source: PMRA Environmental Assessment Division. For more detailed information on the toxicity of specific pesticides to honeybees, refer to the pesticide label. MT = Moderately toxic to bees. Can be used around bees if dosage, timing and method of application are correct, but do not apply them directly on bees, in the field or at the colonies. NT = Relatively non-toxic to bees. Contact = Stays on the surface of plant. Locally systemic = Moves into plant but does not move to other plant parts. Systemic = Moves into plant and to unsprayed plant parts as they develop. SAR = systemic acquired resistance = plant defence inducer Fungicide activity adapted from New York and Pennsylvania Pest Management Guidelines for Grapes and published fungicide efficacy reports.
0 = Ineffective. 1 = Slightly effective/suppression, not recommended for very susceptible varieties or at critical stages of infection. 2 = Moderately effective. 3 = Very effective. NOTE: the ratings in this table are based on the historical rating scale so do not exactly match the ones in the Crop Protection Hub. * (shaded area) = The disease is listed on the product label for control or suppression.
