Pest(s): Downy Mildew
Resistance Management Strategy for:
Group 4 (Phenylamide);
Group 11 (Quinone outside Inhibitor); and
Group 28 + 43 (Carbamate plus Benzamide); and
Group 40 (Carboxylic acid amide) fungicides
Group 49 OSBP (Oxysterol binding protein inhibitor)
- Applications made within the nursery count towards the total number of applications allowed per crop. It is recommended that disease control is started early and maintain a regular program using a fungicide from groups other than Group 4, 11, 28+43, 40 or 49.
- When conditions favour disease development, DO NOT wait for disease to appear, but apply two consecutive sprays of a Group 4, 11, 28+43 or 49 products, at the interval recommended on the label, or a single spray of a Group 11 fungicide. Then resume the program of sprays using products from a different group to the Group 4, 11, 28+43 or 49 products just applied.
- DO NOT apply more than four sprays of a Group 4 or of a Group 40 product per season.
- DO NOT apply more than three sprays of a Group 49 product. Group 49 containing sprays should not consist of more than 33% of the total number of fungicide sprays per crop.
- DO NOT apply more than two sprays of Group 11 or 28+43 fungicide per crop.
- Apply Group 11 fungicides preventively.
- Apply Group 4 and 49 fungicides preventatively and only in mixtures with an effective protectant fungicide from a different mode of action group.
- Continue alternation of fungicides between successive crops. DO NOT make more than (6) six total applications of a Group 49 product per year on the same area targeting the same disease.
