摘要: 利用Sr18真菌的代谢物在保护地(大棚 )对番茄根结线虫病的防治进行了研究,结果表明,施药后28d取样调查,植株高度较对照增加14.5%,证实该菌代谢物对番茄植株无毒害作用;可明显降低土壤中根结线虫二龄侵染幼虫的数量,线虫减退率为68.2%。收获末期调查,Sr18菌液处理的病情指数较对照降低46~55个百分点,防治效果非常显著,并可显著增加番茄产量,增产率为61.72%。

Abstract: The Sr18 fungal metalolites were used in controlling tomato root-knot nematodes(Meloidogyne.sp.)in the greenhouse.The results showed that the metabolites of Sr18 could increase plant height by 14.5%,which means that it did no harm on the tomato plant, and that, it could also reduce the number of second stage juvenil(J2)of tom ato rood knot nematodes by 68.2%.T he result of investigation at harvesting period showed that the control effect was significant and the tomato yield increased by 61.72%.These results indicated that Sr18 fungus could be a prospective strain to develop a new kind of biological control agent for nematodes.

Key words: Meloidogyne incognita, Tomato root-knot nematode disease, Metabolites of fungus, Biological control, Control effect
