What is the acceptable range for herbicide application rate if the measured rate is 1 gpa and a label requires 2.0 qts per acre?

In the context of herbicide application, the measured rate of 1 gallon per acre (gpa) being significantly lower than the required application rate of 2.0 quarts per acre indicates that the application is not meeting the potency or effectiveness as intended by the label's specifications.

Herbicide labels provide specific information about the optimal application rates necessary to achieve the desired control of targeted weeds. If the application rate is lower than what is stipulated, it may result in insufficient control, leading to ineffective weed management and potentially allowing the weeds to thrive or develop resistance.

Therefore, since the measured rate is not within the acceptable range of the required application rate, it is clear that the application would be deemed not acceptable. Proper adherence to the label rates is crucial for ensuring effectiveness and compliance with regulations governing pesticide applications.
