摘　　要：试验采用不同药剂拌种、沟施、叶面喷施等方法,对感染黑痣病的种薯进行处理,通过对出苗率、产量、薯块发病率、地下病茎数的统计分析,研究不同处理方法对马铃薯黑痣病的防治效果,寻求防控马铃薯黑痣病的最佳施药组合。结果表明,不同药剂拌种、沟施、叶面喷施3种方法对马铃薯黑痣病防治均有效果,结合用药成本,防治马铃薯黑痣病经济有效的施药组合是用甲基立枯磷拌种、沟施、叶面喷施。The potatoes which infected by Rhizoctonia solani were treated using seed dressing,furrow fertilization and foliage spraying.Control effects of different treatments on Rhizoctonia solani were studied by statistical analysis of germination rate, yield,the incidence percentage of potato, the number of disease potatoes. The results showed that different treatments to Rhizoctonia solani had good control effects,the best combination of seed dressing by tolclofos-methyl, furrow fertilization and foliage spraying seeking considering medication costs.
