A greenhouse experiment was conducted to evaluate the effects of different inoculum densities of two Saudi isolates of Trichoderma harzianum and Trichoderma viride against Meloidogyne javanica on tomato. Four densities (10(4), 10(6), 10(8) and 10(10) spores/g of soil) of each fungus were used. The results indicate that all four inoculum densities of the two Trichoderma species suppressed the nematode reproduction and root galling; and increased the growth of tomato plants, compared to controls. Efficacy of both fungi increased as their inoculum densities increased. Generally, efficacy of T. harzianum was better than that of T. viride, especially at the highest used density (10(10) spore/g soil) which resulted in the best control.
进行了一项温室试验，以评估两种沙特哈茨木霉和绿色木霉分离株的不同接种密度对番茄上爪哇根结线虫的影响。每种真菌使用了四种密度（10⁴、10⁶、10⁸和10¹⁰个孢子/克土壤）。结果表明，与对照相比，两种木霉菌的所有四种接种密度均抑制了线虫繁殖和根瘤形成，并促进了番茄植株的生长。两种真菌的效果均随着接种密度的增加而提高。一般来说，哈茨木霉的效果优于绿色木霉，尤其是在使用的最高密度（10¹⁰个孢子/克土壤）下，防治效果最佳。
