Disease(s): Downy mildew
Resistance Management Strategy for:
Group 4 Phenylamides (PA);
Group 11 Quinone outside inhibitors (QoI);
Group 28 + 43 Carbamates plus benzamides;
Group 40 Carboxylic acid amide (CAA);
Group 45+40 Quinone outside inhibitors, stigmatellin binding type (QoSI) + CAA;
Group 49 Oxysterol binding protein inhibitors (OSBPI);
Group 49 + 11 OSBPI + QoI;
- 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, 45+40, 49 or 49+11.
- When conditions favour disease development, do not wait for disease to appear, but apply two consecutive sprays of a Group 4, 11, 28+43, 45+40, 49 or 49+11 fungicide, 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, 45+40, 49 or 49+11 fungicide 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 containing product. Group 49 containing sprays should not consist of more than one in every three of the total number of fungicide sprays per crop. Group 49+11 sprays count as both a Group 49 and a Group 11 spray.
- Do not apply more than two sprays of Group 28+43, 45+40 or 11 containing fungicides (including 49+11) per crop.
- Apply Group 4, 11, 45+40 and 49 (including 49+11) fungicides preventatively.
- Apply Group 4 and 49 fungicides only in mixtures or co-formulations with a registered fungicide from a different mode of action group with no known resistance.
- 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.
