Sprays sticking to plants is important for making pesticides work well. A new model was made to predict how well sprays stick to different plants. The model was tested on cotton, wheat, and fat hen plants. The results showed that sprays stick best to cotton and worst to wheat. Bigger droplets stick less, and the type of spray doesn't matter much for cotton but helps stick better to wheat and fat hen. How much spray sticks is influenced by how easily it breaks apart on the plant and how long it takes to break. Understanding these factors can help make sprays work better on plants.
