Group 4 insecticide; Group 4, Group 7 and Group 12 fungicides
Mode of Action
Cruiser Maxx Vibrance Beans includes an active ingredient called sedaxane. It has 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;
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 succinate dehydrogenase inhibitor (SDHI) class of fungicides.
Vibrance penetrates from the seed into the surrounding soil, forming a protective cloud around the seed, developing roots and the lower stem, which helps to strengthen the plant throughout its growing cycle.
Worldwide research increasingly points to root health as the key for future crop productivity improvements. It is estimated that 80% of all plant problems start with soil or root problems. Vibrance helps protect the plant from yield-robbing diseases enabling the seedling to develop a stronger, healthier root system, helping the plant fulfill its maximum genetic potential.
Metalaxyl m = Group 4 = phenylamide – targets RNA polymerase I
Fludioxonil = Group 12 = phenylpyrroles – affects signal transduction
Sedaxane = Group 7 = succinate dehydrogenase inhibitor – affects respiration
Thiamethoxam = Group 4A = neonicotinoid – affects nerve action
For resistance management, please note that Cruiser Maxx Vibrance Beans Seed Treatment contains Group 4, Group 7 and Group 12 fungicides and a Group 4 insecticide. Any fungal and (or) insect population may contain individuals naturally resistant to Cruiser Maxx Vibrance Beans Seed Treatment and other Group 4, Group 7 or Group 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.
Resistance Management (cont’d):
To delay insecticide and fungicide resistance:
Where possible, rotate the use of Cruiser Maxx Beans Seed Treatment or other Group 4, Group 7 and Group 12 fungicides and Group 4 insecticides with different groups that control the same pathogens/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 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 pathogens or pest problems in your area.
