For resistance management, please note that Delaro Complete contains a Group 3, Group 11 and Group 7 fungicide. Any fungal population may contain individuals naturally resistant to Delaro Complete and other Group 7 and Group 3 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. Appropriate resistance-management strategies should be followed.
To delay fungicide resistance:
- Where possible, use multiple mode of action products while deploying group rotational management to reduce the risk of pathogen resistance development
- Do not apply more than the indicated maximum number of applications per year specified for each crop
- 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. Where possible, make use of predictive disease models to effectively time fungicide applications.
- Monitor treated fungal populations for resistance development. Notify Bayer if reduced sensitivity of the pathogen to Delaro Complete is suspected.
- 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.
