Weed Blast 4-G is a nonselective herbicide for controlling a wide range of annual and perennial weeds and grasses. It is registered for industrial use only such as railroad, utility and highway rights-of-way. 200 to 400 pound applications of Weed Blast 4-G per acre usually result in a nonproductive condition of the soil for a period of a year or more. The duration of nonproductivity is dependent upon rainfall, soil type, and other conditions. Weed Blast 4-G should be applied as furnished with a seed spreader, a fertilizer spreader,or with any equipment which will distribute the chemical uniformly over the area to be treated. For the control of annual and most perennial weeds and grasses, apply Weed Blast 4G at the rate of 200 to 400 pounds per acre; on smaller plots, 1/2 to .92 pound per 100 square feet. Repeat spot treatment may be required when deep rooted perennial weeds are present. To obtain the best results, Weed Blast 4-G should be applied to the ground where it will be absorbed by the roots. Applications made early in the season have been found to give results superior to applications at a later seasonal date. Weed Blast 4-G may, however, be applied at any time of the year except when the ground is frozen. Not to be used in any recreational areas or in or around homes. May not be used to treat berms of ditches, seasonally dry flood plains, deltas, marshes, swamps, bogs, and transitional areas between upland and lowland sites. Do not apply on or near desirable woody or herbaceous plants or on areas where their roots may extend because of possible injury to such plants. Thoroughly clean spreading equipment with a suitable chemical cleaner before using for other purposes (or do not use same spreading equipment for other purposes). Dispose of rinsate according to Disposal instructions found under Storage and Disposal heading. Do not use on croplands or any land to be used for subsequent cropping. Keep animals off treated areas.
