What is the ideal aquatic condition for applying herbicides to submerged plants?

Calm water conditions are ideal for applying herbicides to submerged plants because they promote better targeting of the herbicide, allowing it to remain in contact with the target plants without being disturbed or washed away. When water is calm, the chemical can effectively penetrate the plant tissues and minimize drift, ensuring that the herbicide is utilized efficiently. This leads to improved absorption by the plants, enhancing the effectiveness of the treatment. Additionally, calm conditions reduce the potential for unintended contamination of non-target areas, making the application more precise and environmentally responsible.
