How Atplus Rainfast Pro supports rainfastness

Rainfall or irrigation can wash active ingredients from the plant surface before they have delivered their intended effect. This may reduce performance and increase the risk of additional applications.

Atplus Rainfast Pro forms a film that helps retain spray deposits on the treated surface, supporting the performance of crop protection formulations after exposure to water.

Key benefits

Helps reduce spray-deposit wash-off after rainfall or irrigation
Supports retention of the active ingredient on the treated surface
Supports biological efficacy under the tested conditions
Designed for incorporation into crop protection formulations
