PURPOSE:To control plant-parasitizing nematodes giving damages to crops by employing both Pasteuria bacteria parasitizing in the nematodes and a mold catching the nematodes or employing three kinds of the microorganisms further containing a mold parasitizing in eggs. CONSTITUTION:Both a Pasteuria bacterium parasitizing in nematodes and a mold catching the nematodes (the Dactylella mold and the Monacrosporium mold having relatively high favoritism on nematodes parasitizing in plants are especially preferable) are used for controlling the nematodes parasitizing in the plants. Otherwise, three kinds of the microorganisms consisting of the Pasteuria bacterium parasitizing in the nematodes, the mold catching the nematodes and a mold parasitizing in eggs (especially the Paecilomyces mold or the Verticillium mold is suitable, but the mold producing spores or mycelia having thick membranes is especially preferable) are used for controlling the nematodes parasitizing in the plants. The simultaneous employment of three of pasteuria, a nematode-catching mold: dactylella, and an egg- parasitizing mold: verticillium gives the highest effect. Secondly, the simultaneous employment of the pasteuria and the nematode-catching mold: dactylella gives the high effect. |
