Previous cropping sequence (corn-soybean vs. soybean-soybean) and aldicarb effects on soybean yield and nematode numbers at harvest for soybean cultivars with various combinations of nematode resistance were determined in 1988 in a sandy loam soil infested with Meloidogyne arenaria race 2 and Heterodera glycines races 3 and 4 at Elberta, Alabama. Yield and nematode numbers differed among cultivars with 'Leflore' having the highest yield. Aldicarb treatment resulted in increased soybean yield but did not affect nematode numbers. Previous cropping sequence did not affect soybean yield or numbers of H. glycines, but soybean following corn-soybean had higher numbers of M. arenaria than soybean following soybean-soybean. The only significant statistical interaction was aldicarb x cultivar for numbers of H. glycines.
1988年，在阿拉巴马州埃尔伯塔市一块受南方根结线虫2号小种和大豆胞囊线虫3号及4号小种侵染的砂壤土中，针对具有不同线虫抗性组合的大豆品种，测定了前茬种植顺序（玉米-大豆与大豆-大豆）以及涕灭威对大豆产量和收获时线虫数量的影响。不同品种的产量和线虫数量存在差异，‘莱弗洛’产量最高。涕灭威处理使大豆产量增加，但对线虫数量没有影响。前茬种植顺序对大豆产量或大豆胞囊线虫数量没有影响，但玉米-大豆后茬种植的大豆上南方根结线虫数量比大豆-大豆后茬种植的大豆上的多。唯一显著的统计交互作用是涕灭威×品种对大豆胞囊线虫数量的影响。
