What is the rate of Prowl H2O Herbicide application?

The application rate of Prowl H2O Herbicide indeed varies by crop, making this choice the correct answer. Prowl H2O is designed to control a range of weeds in various crops, and the specific rate of application can depend on several factors, such as the type of crop being treated, the size and density of the weeds, and environmental conditions.

Agronomists and farmers must refer to the product label and local agricultural guidelines to determine the most effective and safe application rate for their specific situation. This flexibility allows for optimal weed management while minimizing risk to the crop itself.

In contrast, the other options provide specific ranges or amounts which may not be universally applicable across all crops. While they may be relevant for some situations, they do not capture the necessary adaptability in application rates required for effective use of the herbicide across different agricultural practices.
