Rhizoctonia root rot caused by Rhizoctoniasolani is a major disease of wheat worldwide.

由Rhizoctonia solani引起的小麦丝核菌根腐病是世界范围内小麦的主要病害之一。

At the primary screening test, 23 species of CHEs had significant inhibitory effects against the mycelium growth of Rhizoctonia solani with the inhibitory rates over 50%. Inhibitory effect of Celosia cristata L. extract reached up to 100%.

供试的126种中草药提取物中有23种提取物对立枯丝核菌菌丝生长具有显著的抑制作用，且抑菌作用大于50%，鸡冠花提取物的抑菌率达到100%。

The phylogenetic analyses suggested that the YLS of BPH with different virulence belonged to the subphylum Ascornycotina, the class Pyrenomycetes, and had the closest genetic relationship with Hypomyces chrysospermus.

结果显示，褐飞虱3种不同致害性种群体内的YLS同属子囊菌亚门的核菌纲，并与此纲中的Hypomyces chrysospermus亲缘关系相对最近。

Three-hundred and ninety-nine fungal isolates were obtained from 686 diseased cotton seedlings and soil samples collected from cotton production areas in Northern Xinjiang by using the conventional method,among which 272 strains of R.solani were identified.Based on Giemsa staining,all strains were identified as multinucleate Rhizoctonia solani .

从新疆北疆棉区采集了典型的棉花立枯病病苗及棉田土标样686份，按常规分离方法分离得到399个分离物，从中鉴定出272个纯化的立枯丝核菌( Rhizoctonia solani Kühn)菌株。

A total of 1971 strains of endophytic fungi was isolated. As a result of morphological identification 32 genera were obtained, of which Alternaria (amounting to 18.01% of the total), Phyllosticta (14.66%) and Rhizoctonia (14.56%) were dominant.

结果表明：所分离出的1971株内生真菌可归于32属，以交链孢属Alternaria（18.01%）、叶点霉属Phyllosticta（14.66%）和丝核菌属Rhizoctonia（14.56%）为优势菌群。

Studies on Pathogenic Species of Pythium from Cool-season Turfgrasses in Zhejiang Province;2. The results indicated that the main turfgrass diseases were brown patch, pythium and fuarium diseases.

对北京市海淀区部分草坪的病害种类调查表明：草坪的病害主要是由丝核菌属、腐霉菌属、镰刀菌属引起的褐斑病、腐霉枯萎病和镰刀枯萎病。

Solani with ID50 beyond 10. The isolate F0028, which has the highest inhibitory rate against P. ultimum (ID50 of 278±15.0) and R. solani (ID50 of 108±18.6) was identified as Aspergillus clavatonanicus.

其中矮棒曲霉Aspergillus clavatonanicus菌株F0028对这两种病原菌的活性最高（对终极腐霉、立枯丝核菌的ID50分别为278±15.0、108±18.6）。

The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

试验结果显示：浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用，香草酸也有一定的促进作用，但不呈浓度效应，浓度在1mM/L以上的香豆酸对其有显著的抑制作用，阿魏酸也有一定抑制作用；对于西洋参根腐菌，阿魏酸对其生长有明显促进作用，香豆酸也有一定促进作用，香草酸表现为低浓度促进，高浓度抑制作用，0.1~1mM/L丁香酸对其生长基本无影响。
