To limit the potential for development of disease resistance to this fungicide class do not make more than 2 sequential applications of any Group 7-containing fungicide before rotating with a fungicide from a different Group registered for the same use. When Velum Rise is applied as a soil application use a non-Group 7 product such as Scala® fungicide for the first foliar fungicide application.
Maximum seasonal application rates:
Fluopyram: Do not apply more than 500 g/ha (202 g/ac.) fluopyram per year, regardless of formulation or method of application (soil or foliar).
Penflufen: Do not apply more than 160 g/ha (65 g/ac.) penflufen per year, regardless of formulation or method of application (seed-piece treatment or in-furrow).
Any nematode or fungal population may contain individuals naturally resistant to Velum Rise and other Group 7 nematicides/fungicides. A gradual or total loss of nematode control may occur over time if this product is used repeatedly in the same field. 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 nematicide/fungicide resistance:
- Where possible, rotate the use of Velum Rise or other Group 7 nematicides/fungicides with different Groups that control the same pests
- When Velum Rise is applied as a soil application use another mode of action for the first foliar fungicide application. Scala fungicide (Group 9) is an excellent choice for the first foliar fungicide application.
- Avoid consecutive applications of Velum Rise or other Group 3 or Group 7 nematicides/fungicides in a season. Alternate applications with fungicides having a different mode of action.
- Nematicide/fungicide use should be based on an integrated disease management program that includes scouting, historical information related to pesticide use and crop rotation and considers host plant resistance, impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other chemical control practices
- Early blight pressure should be monitored throughout the growing season. Heavy disease pressure may require additional systemic foliar fungicide applications.
- Monitor treated nematode populations for resistance development
- 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
