Rate 0.5 to 1 lb ai/A (1 to 2 pints/A Basagran 4L or 0.8 to 1.6 pints/A Basagran 5L)
Time Apply postemergence to actively growing weeds in the 2- to 10-leaf stage of growth (refer to label). Beans must have first trifoliate leaf fully expanded.
Remarks Tolerant bean types are adzuki, navy, pinto, pink, great northern, kidney, red, white, cranberry, black turtle, small lima, large lima, and snap beans. Controls certain annual broadleaf weeds, including nightshade and cocklebur. Can control Canada thistle and yellow nutsedge with two applications 7 to 10 days apart. Basagran is effective mainly through contact action. Therefore, weeds must be thoroughly covered with spray. Does not control grasses. May be tank mixed with dimethenamid-P, imazamox, imazethapyr, and sethoxydim. Add crop oil concentrate (COC) at 1% v/v (1 gal/100 gal spray solution), methylated seed oil (MSO) containing at least 60% MSO at 1% v/v, or nonionic surfactant (NIS) containing at least 80% active ingredient at 0.25% to 0.5% v/v (1 to 2 quarts/100 gal spray solution). Organosilicone surfactant may be used in place of NIS. Ammonium sulfate (AMS) at 8.5 to 17 lb/100 gal spray solution or urea ammonium nitrate (UAN) such as 32% N or 10-34-0 at 1.25 to 2.5 gal/100 gal spray solution may also be added to improve weed control. Additives may cause some leaf burn, but new growth is normal and crop vigor is not reduced. Injury potential is increased when relative humidity and temperature are high. Irrigation may be needed before application to ensure weeds are growing actively. Rainfall or overhead irrigation within 4 hr after application may reduce effectiveness. REI 48 hr.
Caution Bean leaves may temporarily yellow, bronze, or speckle under some conditions. Do not apply in cool weather (days below 75°F and nights below 55°F for two to five days) or weed control will be poor. Do not apply to stressed beans or to garbanzo beans. Do not exceed 2 lb ai/A (3.2 pints/A Basagran 5L, 4.0 pints/A 4L) in one season. Do not apply if rain is expected within 4 hr. Do not cultivate within 5 days before or after application. Do not apply to dry or succulent beans within 30 days of harvest.
