Groups 1, 4, 11 and 12 fungicides; Group 28 insecticide
Cyantraniliprole - Group 28 insecticide – Diamides – affects insect nerve and muscle system
Metalaxyl m = Group 4 = phenylamide – targets RNA polymerase I
Fludioxonil = Group 12 = phenylpyrroles – affects signal transduction
Azoxystrobin = Group 11 = Quinone outside Inhibitors – Affects cellular respiration
Thiabendazole = Group 1 = Methyl Benzimidazole Carbamates – Affects mitosis
For resistance management, please note that Fortenza Maxim Quattro contains a Group 28 insecticide and Groups 1, 4, 11 and 12 fungicides.
Any insect population may contain individuals naturally resistant to Fortenza and other Group 28 insecticides. The resistant individuals may dominate the insect population if this group of insecticides is used repeatedly in the same field. 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.
Where possible, rotate the use of FORTENZA or other Group 28 insecticides with different groups that control the same pests in a field. Where possible rotate the use of MAXIM QUATTRO Seed Treatment or other Group 1, 4, 11 or 12 fungicides with different groups that control the same pathogens.
Any fungal population may contain individuals naturally resistant to MAXIM QUATTRO Seed Treatment and other Group 1, 4, 11 or 12 fungicides. A gradual or total loss of pest control may occur over time if these fungicides 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.
Use tank mixtures with miticides/insecticides/fungicides from a different group when such use is permitted.
Insecticide and fungicide use should be based on an IPM program that includes scouting, record keeping, and considers cultural, biological and other chemical control practices.
Monitor treated pest populations for resistance development. If insect resistance is suspected, do not reapply FORTENZA or other Group 28 insecticides. 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 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 the specific site and pest problems in your area.
