Group 4 insecticide; Group 3, Group 4, Group 7 and Group 12 fungicides
Mode of Action
The active ingredient in Vibrance is sedaxane, a mode of action which:
Defends roots against certain diseases carried in soil and air as well as against seed infection with best in class Rhizoctonia activity;
Combines systemic movement with ideal soil mobility;
Provides long-lasting protection of the entire root system through all critical crop development stages and under a wide range of environmental conditions;
Belongs to the Pyrazole-Carboxamide class of chemistry – a new succinate dehydrogenase inhibitor (SDHI) class of fungicides.
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
For resistance management, Helix Vibrance contains a Group 4 insecticide and Groups 3, 4, 7 and 12 fungicides. Any insect or fungal population may contain individuals naturally resistant to Helix Vibrance and other Group 4 insecticides or Groups 3, 4, 7 and 12 fungicides. A gradual or total loss of pest control may occur over time if these insecticides and fungicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are 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 Helix Vibrance or other Group 4 insecticides and Groups 3, 4, 7 and 12 fungicides with different groups that control the same insects or pathogens.
Insecticide and fungicide use should be based on an 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 insect and fungal populations for resistance development.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for specific crops and pests problems in your area.
