They were divided into three groups. The first group, included most of highly virulent isolates from different corn-growing areas, exhibited high similarity in RAPD patterns and completely identical ITS sequence except for one isolate.

第一组为优势组，多数菌株间相似性高，在ITS区域具有完全相同的DNA序列，包含来自各发病区的大多数致病菌株，是引起玉米弯孢菌叶斑病的优势类群。

Identification of disease and pest resistance was done by Institute of Plant Protection, Hebei Academy of Agricultural Science, and the variety demonstrated resistance to southern blight leaf; mid-resistance to stalk rot, corn Curvularia leaf spot; high resistance to northern blight leaf, corn smut, corn dwarf mosaic; and sensitive to corn borer.

项目简介：中单808由中国农业科学院作物育种栽培研究所选育，生育期126天左右，株高314cm左右，穗长21.8cm，2004年河北省农林科学院植物保护研究所抗病鉴定结果：抗小斑病，中抗弯孢菌叶斑病，茎腐病，高抗大斑病，瘤黑粉病，矮花叶病，感玉米螟。2005年西南生产试验中平均亩产571.29kg，比对照增产17.85%。

The research aimed to determine the pathogen caused by the leaf spot disease of ornamental pineapple, and screen effective fungicides.

Cucumber target leaf spot is a serious disease in greenhouse in Shandong province.

对黄瓜棒孢叶斑病在山东省的为害、症状特点、生物学特性以及病原菌的鉴定进行了研究。

Pathogenicity of 83 Curvularia isolates including 76 isolates from corn and 7 isolates from other hosts were tested in seedling and adult stage of corns. Among these species based on morphology, C. lunata, C. pallescens, C. lunate var. aeria, C. clavata and C. ovoidea could cause the typical Curvularia leaf spot symptom that lesions are grayish spots up to 1mm in diameter appear in the centers and straw-colored or chlorotic halos may surround the lesions.

以上方面的研究结果表明：通过形态鉴定，来自玉米弯孢菌叶斑病病害标样中的148株弯孢菌被鉴定为9个种和1个变种，即新月弯孢菌、苍白弯孢(C.pallescens)、新月弯孢菌气生变种(C.lunata var.aeria)、棒弯孢、C.ovoidea、不等弯孢(C.inaequalis)、塞河弯孢(C.senegalensis)、香茅弯孢(C.cymbopogonis)、Curvularia sp〓和Curvularia sp〓。

At the same time, we carried on to observe the pathogenic plant disease symptom characteristic in detail. 3. In lab,experimental result expressed that Difenoconazole 10% WP and Propiconazol 25% EC have the highest control effect, wheras Carbendazim 98％ WP and metalaxyl 25% WP almost can not repress development of cotton leaf spot pathogens.

室内药剂筛选试验研究表明，25%丙环唑乳油、10%世高可湿性粉剂对棉花叶斑病致病菌具有很好的抑菌效果，这两种杀菌剂的作用效果普遍高于其它药剂，是较为理想的化学防治药剂；98％多菌灵可湿性粉剂和25%甲霜灵可湿性粉剂，抑菌效果不理想，对病原菌生长的抑制作用普遍不明显。

The leaf spot disease was more severe with the increase of planting density.
