Irene Batista de Oliveira Pedrozo, Martin Homechin

Abstract


The soybean cyst nematode (SCN) Heterodera glycines Ichinohe, is the most important pest of soybean in the United States, eastern Asia and Brazil. The effects of abamectin (Vertimec 18 CE) on the NCS was evaluated under a greenhouse conditions. Three abamectin rates (lOO, 200 and 300 ml p.c/ha) were sprayed above ground of soybeans plants at 15, 21, 28 and 35 days after the transplant (d.a.t.). Aldicarb (Temik 10 G). 0,07g/ pot was incorporated to the soil short after the transplantation. Abamectin increased significantly plant height and the weight of fresh and dry root system and above ground part of soybean plants, and reduced significantly the number of females/g of roots when compared to the check and the aldicarb,
