Testing is essential. Suitable test rates should be used on a small portion of the crop before doing extensive treatment. Select the rate which provides the desired effect. The actual conditions at your facility may not be the same as the place were the data was obtained. You might find highly successful results if you vary the concentrations somewhat from the listed amount. | Warranty |
