Abstract

Field experiments were conducted in 1983 and 1984 on a Dothan loamy sand at Headland, AL to evaluate herbicide systems for minimum tillage peanut (Arachia hypogaea L. Florunner) production. The influence of minimum tillage-herbicide systems on weed control, peanut yield, market grade, and net returns were examined. Two minimum tillage-herbicide systems provided greater yield and higher net returns with equivalent control of Texas panicum (Panicum texanum Buckle.) and Florida beggarweed Desmodium tortuosum (SW.)DC as compared to a conventional tillage-herbicide system. One of these systems included oryzalin [4-(dipropylamino)-3, 5-dinitrobenzenesulfonamide] and paraquat (1, 1-dimethyl-4,4bipyridinium ion) applied preemergence followed by an early postemergence application of acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methylphenyl)acetamide] and dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] and a postemergence-directed application of cyanazine (2-[[4-chloro-6-(ethylamino)-1,3,5-triazin-2-yl]amino]-2-methylpropanenitrile). The other system included benefin [N-butyl-N-ethyl-2,6-dinitro-4-(trifluoromethyl)benzenamine] and metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2)methoxy-1-methylethyl)acetamide) applied preplant-incorporated within-the-row followed by an early postemergence application of dinoseb and ethalfluralin [N-ethyl-N-)2-methyl-2-propenyl)-2,6-dinitro-4-(trifluoromethyl) benzenamine] and a postemergence-directed application of paraquat. Herbicide inputs for these two minimum tillage-herbicide systems were greater than for the conventional tillage-herbicide system.
