Anilazine solution is primarily used as a fungicide in agriculture. It is effective in controlling various fungal diseases in crops, especially in potatoes, tomatoes, and other vegetables. It helps prevent and manage diseases such as early blight and leaf spot by inhibiting fungal growth. The solution is typically applied as a foliar spray, offering protective action when used before infection occurs. It is valued for its systemic activity, meaning it can be absorbed by plant tissues and provide internal protection. Anilazine is often included in integrated pest management programs to reduce reliance on single-mode fungicides and help delay the development of resistance.
