Group 4 insecticide; Group 3, Group 4, Group 7 and Group 12 fungicides.
Mode of Action
Cruiser Vibrance Quattro contains the active ingredients thiamethoxam, difenoconazole, sedaxane, metalaxyl-M (and S-isomer) and fludioxonil.
Metalaxyl m = Group 4 = phenylamide – targets RNA polymerase I
Fludioxonil = Group 12 = phenylpyrroles – affects signal transduction
Sedaxane = Group 7 = succinate dehydrogenase inhibitor – affects respiration
Difenoconazole = Group 3 = triazole – inhibits sterol biosynthesis
Thiamethoxam = Group 4A = neonicotinoid – affects nerve action
Experience has shown that strains of fungus resistant to metalaxyl-M (and S-isomer) may develop. Failure to control the disease will result in crop damage and/or yield losses. Since the occurrence of the resistance cannot be foreseen, Syngenta Canada Inc. accepts no responsibility for any loss of, or damage to, crops resulting from the failure of Cruiser Vibrance Quattro to control the resistant fungus strains. If disease appears in a treated field, consult the government extension specialist immediately.
For resistance management, please note that Cruiser Vibrance Quattro contains Groups 3, 4, 7 and 12 and a Group 4 insecticide. Any fungal and (or) insect population may contain individuals naturally resistant to Cruiser Vibrance Quattro and other Groups 3, 4, 7 or 12 fungicides and Group 4 insecticides. A gradual or total loss of pest control may occur over time if these fungicides/insecticides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.
To delay insecticide and fungicide resistance: Where possible, rotate the use of Cruiser Vibrance Quattro or other Groups 3, 4, 7 and 12 fungicides, Group 4 insecticides with different groups that control the same pathogens/insect pests. Fungicide and insecticide use should be based on an Integrated Pest Management (IPM) program that includes scouting, historical information related to pesticide use and crop rotation and considers cultural, biological and other chemical control practices. Monitor treated fungal and insecticide populations for sign of resistance development. If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide and insecticide product with a different target site of action, if available.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and (or) IPM recommendations for specific crops and disease problems in your area.
