Post Emergent Broadleaf Herbicide

Basagran (bentazon) can be applied as sequential treatments for greater broadleaf weed control. The first Basagran application should be made before the weeds are 0.5 to 4 inches tall, depending on the weed species. Refer to label for information on weed sizes at application. Apply Basagran at 1 pt/A plus petroleum oil or Dash HC at 0.5 to 1 pt/A and repeat the application 7 to 10 days later. Basagran applied as a planned split application program will improve broadleaf weed control compared to a single application. Split applications will control cocklebur, lambsquarters, annual smartweed, VENICE mallow, and wild mustard. Common ragweed, kochia, pigweed, and sunflower may be controlled or suppressed. NDSU research has shown greater control of lambsquarters, redroot pigweed and kochia by applying Basagran as split treatments either twice each at 1 pt/A, 3 times each at 0.67 pt/A, or 4 times each at 0.5 pt/A as compared to one application at 2 pt/A. Dash HC gives greater enhancement of Poast than petroleum oil or AMS.

Pursuit (imazethapyr) at 2 fl oz/A or Pursuit DG at 0.72 oz/A or 10 acres per water soluble packet applied POST only controls wild mustard and provides suppression of nightshade in pinto, navy, great northern, kidney, black turtle, and cranberry type dry beans. Reduced crop growth, yield, and/or delayed maturity may result from application. Do not apply if planting is delayed, or cold and/or wet weather are present or predicted to occur within one week of application. Do not apply to Domino variety black turtle bean. Pinto varieties UI-111 and Olathe are more sensitive to injury than other Pinto varieties. Apply Pursuit with NIS at 0.25% v/v to dry beans having at least one trifoliate leaf. DO NOT use oil additives, liquid fertilizer or DASH. Refer to the Raptor paragraph in the soybean section for additional information on application use and restrictions. See Pursuit under the herbicide residue section for information on crop rotation restrictions.

Raptor (imazamox) is labeled and has few crop rotation restrictions. Raptor applied at 4 fl oz/A when preceded by a soil applied grass herbicide registered in soybean controls many annual grass and broadleaf weeds in soybean. Refer to the Raptor paragraph in the soybean section of the weed guide for information on imazamox (Raptor) application and adjuvant use and restrictions.
