All rights reserved. 2 Herbicide Resistance West & High a n d Repeated use of Poast(or similar postemergence grass herbicides with the same mode of action)may lead to the selection of naturally occurring biotypes with Rolling Plains resistance to these products. If poor performance cannot be attributed to adverse weather conditions or improper application methods,a resistant biotype may be present. Consult your local representative or agricultural advisor for assistance. - Irrigation In irrigated areas,it may be necessary to irrigate before treatment to ensure active _ weed growth. - Cultivation Do not cultivate within 5 days before or 7 days after applying Poast. Cultivating - 7 days or later after treatment may help provide season-long control. Cleaning Spray Equipment = -� Clean spray equipment thoroughly using a strong detergent or commercial sprayer cleaner according to the manufacturer's directions before and after applying this product. H.Application Instructions Applications can be made to actively growing weeds as aerial, broadcast,band, i or spot spray applications at the rates and growth stages listed in Tables 1, 2 1 and 3, unless instructed differently in section VI. Crop-Specific Information. The most effective control will result from making postemergence applications of Poast early,when weeds are small. Delaying application permits weeds to exceed the maximum size stated and may prevent adequate control. Apply Poast to the foliage of grasses uniformily and completely because large leaf canopies shelter smaller weeds and can prevent adequate spray coverage.
