Research Papers: Effects on Soybeans and Nematode Populations of Three Soil Fumigants Applied at Several Rates at Time of Planting
Year: 1979
Type: article
Abstract: Various rates of ethylene dibromide, DD, and 1,3-D injected at planting to a depth of 20 cm with two chisels per row set 25 cm apart increased soybean yields and reduced population levels of Meloidogyne incognita and Helicotylenchus sp. in a Fuquay loamy sand. Liters per ha of active ingredient that increased yields significantly were: ethylene dibromide, 4.67, 9.34, 18.68, 37.36, and 56.04; DD, 18.68, 37.36, and 74.72; 1,3-D 18.68 and 37.36. The average yield increase for these rates was 31%. Yield differences among pesticide rates were not significant. Yields were not increased significantly with DD at 7.01 1/ha, 1,3-D at 9.34 1/ha and phenamiphos at 2.8 kg a.i./ha. DD at 74.72 l/ha was phytotoxic.
