Effects of Paraquat Application and Timing on Peanut (Arachis hypogaea L.) Growth, Yield and Grade
Year: 2016
Type: article
Abstract: Field studies were conducted to evaluate paraquat or paraquat and bentazon mixtures and timing of application on runner-type peanut yield, injury, and grade. Single applications of paraquat at 0.14 kg ha-1 reduced peanut plant growth when applied 7, 14, 21, and 28 days after peanut emergence (DAE). Multiple applications of paraquat applied at peanut emergence (Emergence) and 14 DAE, 7 and 21 DAE, 14 and 28 DAE, and 7 and 28 DAE reduced peanut plant growth more than single applications. Paraquate applied at 21 DAE, Emergence and 14 DAE, 7 and 21 DAE, and 14 and 28 DAE reduced peanut yield when compared with pendimethalin at 0.84 kg ha-1 applied preplant incorporated (PPI). Peanut grade was not affected by any paraquat treatments. Tank mixes of paraquat+bentazon resulted in less peanut stunting than paraquat alone and treatment yields did not differ from the pendimethalin treatment.
