A series of greenhouse, phytotron, field, and microplot experiments evaluated factors that influenced plant-growth.stimulation associated with the use of the pesticide aldicarb. A phytotron experiment showed.that aldicarb increased growth, of Ransom soybean at all temperatures but was somewhat phytotoxic to Coker 156 soybean at 30 C. Soybean gave the greatest response to this nematicide at 22 C in a commercially available medium, Metromix 220. Soybean cultivars Ransom and Coker 156. exhibited increased growth in response to aldicarb or, to a lesser extent aldicarb sulfone treatments under greenhouse and microplot conditions. Enhanced soybean growth, however, did not always result in significantly greater soybean seed yield. Soil type affected soybean sensitivity to aldicarb, with. the greatest growth and yield increases generally occurring in fine-textured soils or those with high.organic matter. Plant-growth stimulation by aldicarb occurs in the absence of pests but is dependent upon concentration and edaphic and other environmental factors.
一系列温室、人工气候室、田间和小区试验评估了影响与使用涕灭威这种杀虫剂相关的植物生长刺激作用的因素。一项人工气候室试验表明，涕灭威在所有温度下均能促进兰塞姆大豆的生长，但在30℃时对科克尔156大豆有一定的药害。在市售基质“美乐棵220”中，大豆在22℃时对这种杀线虫剂的反应最为强烈。大豆品种兰塞姆和科克尔156在温室和小区条件下，对涕灭威或在较小程度上对涕灭威砜处理表现出生长增加。然而，大豆生长的增强并不总是导致大豆种子产量显著提高。土壤类型影响大豆对涕灭威的敏感性，一般在质地细的土壤或有机质含量高的土壤中，大豆的生长和产量增加最大。涕灭威在没有害虫的情况下也能刺激植物生长，但这取决于浓度以及土壤和其他环境因素。
