Fortenza: Group 28 insecticide
Helix Vibrance: Group 4 insecticide; Group 3, Group 4, Group 7 and Group 12 fungicides
Mode of Action
Fortenza contains the insecticide cyantraniliprole.
Helix Vibrance contains the insecticide thiamethoxam and the fungicides difenoconazole, metalaxyl-M, fludioxonil and sedaxane.
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
Cyantraniliprole - Group 28 insecticide – Diamides – affects insect nerve and muscle system
For resistance management, please note that this product contains Group 28 and 4 insecticides, as well as Groups 3, 4, and 12 fungicides. Any insect or fungal population may contain individuals naturally resistant to these groups. The resistant individuals may dominate the insect population if this group of insecticides is used repeatedly in the same field. 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. Because resistance development cannot be predicted, the use of this product should conform to sound resistance management strategies established for the crop and use area.
Resistance Management (cont'd):
To delay insecticide and fungicide resistance:
Where possible, rotate the use of this product or other Group 4 and 28 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.
