Abstract
Summary. Comparative studies of herbicides and herbicide mixtures in peanuts (groundnuts) were continued at Tifton, Georgia, U.S.A., on Tifton loamy sand during 1961–63. When applied on a dry soil surface at the ‘cracking’ stage, certain mixtures which contained dinoseb as one component with 2,4‐DES, 2,4‐DEP, or DMPA as the Other component gave control of Digitaria sanguinalis (L.) Scop. and Richardia scabra St. Hil. for the entire growing season. However, on wet soils with no subsequent rain during the first weeks or with prolonged excess moisture, mixtures were not appreciably more effective than herbicides applied singly at standard rates. Where mixtures were applied on wet soil, herbicide effectiveness was improved by timely follow‐up sprays of dinoseb at 1.5 lb/ac. Timing of application was often critical for optimum weed control. The best time was when the peanuts were cracking the ground or when the first weeds were barely visible, whichever occurred first. Mixtures permitted the use of the lowest rate of each compound on the weeds for which it was most effective. A mixture of DMPA at 6 lb/ac 4—dinoseb at 3 lb/ac applied at the ‘ground‐cracking’ stage increased the average yield of peanuts. The mixtures evaluated had no effect on shelling‐%, % sound mature kernels (SMK), mean weight per nut, or % germination. Neither did they affect taste of the peanuts or other sensory. characteristics. However, preliminary chemical analyses indicated that peanuts treated with mixtures contained more linolein and less olein than did untreated peanuts.
