用非致病丝核菌培养物覆盖播种过小麦种子的土壤，进行小麦纹枯病的防治试验。室内外盆栽试验结果表明，对小麦纹枯病有明显的防治效果。室内的相对防治效果为６１．０％～９０．１％，室外的防治效果为６０．８％～６１．３％。不同的非致病丝核菌株防治效果不同。过氧化物酶同功酶的测定结果表明，接种非致病丝核菌后小麦过氧化物酶同功酶增加１条酶带。
Soil covered with wheat seeds was covered with non-pathogenic Rhizoctonia cultures for the control of wheat sheath blight. Indoor and outdoor potted trial results show that there is a clear control effect on wheat sheath blight. Indoor relative control effect of 61.0% ~ 90.1%, outdoor control effect of 60.8% ~ 61.3%. Different non-pathogenic Rhizobium strains have different control effects. Peroxidase isozyme assay results showed that after inoculation of non-pathogenic Rhizoctonia wheat peroxidase isozymes added an enzyme band.
