No more downy mildew in grapevie,

Downy mildew is a serious fungal disease that can affect all parts of the grapevine, including the leaves, shoots, flowers, and fruit. It is caused by the fungus Plasmopara viticola, which thrives in cool, wet weather.

Symptoms of Downy Mildew

The most common symptoms of downy mildew are:

• Yellow oil spots on the upper surface of leaves
• White, downy growth on the underside of leaves
• Browning and death of leaves
• Browning and death of shoots and flowers
• Cracking and splitting of fruit

Management of Downy Mildew

There are a number of ways to manage downy mildew, including:

• Cultural practices: Plant vines in well-drained soils and avoid overwatering. Space vines so that there is good air circulation. Prune vines to promote good air flow and sunlight penetration. Remove and destroy infected plant parts.
• Fungicides: There are a number of fungicides that can be used to control downy mildew. Bayer Profiler is a new combination fungicide that is highly effective against downy mildew. It has a unique mode of action and provides long-duration control.

Recommendation of Bayer Profiler

Bayer Profiler is the most effective systemic fungicide for the control of downy mildew on grapes. It has a number of advantages over other fungicides, including:

• Systemic, contact, and translaminar activity: Profiler is absorbed by the plant and moves throughout the vascular system, providing protection from the inside out. It also has contact and translaminar activity, which means that it can kill spores that come into contact with it or that germinate on the surface of the leaf.
• Unique mode of action: Profiler has a unique mode of action that is different from other oomycete fungicides. This makes it less likely that the fungus will develop resistance to Profiler.
• Long-duration control: Profiler provides long-duration control of downy mildew, reducing the need for frequent applications.
• Excellent protection of new leaves and hidden bunches: Profiler is particularly effective at protecting new leaves and hidden bunches, which are most susceptible to downy mildew infection.

Application of Bayer Profiler

Bayer Profiler should be applied using a high-volume knapsack sprayer. The recommended rate is 2.0-2.5 ml/liter of water. Profiler can be applied from the 3-4 leaf stage after pruning or as soon as downy mildew symptoms are seen. It can be repeated 2-3 times in a season with a 10-15 day interval, depending on disease severity.

Conclusion

Bayer Profiler is the most effective systemic fungicide for the control of downy mildew on grapes. It has a unique mode of action and provides long-duration control, making it an ideal choice for grape growers.
