The studies on biological characteristic revealed that the optimal temperature for the mycelial growth was 25~30℃, and the optimal pH for mycelial growth was pH 5~7. Among carbon and nitrogen sources, sucrose and calcium nitrate were best for mycelial growth. The lethal temperature for mycelial growth and spores gemination were respectively 55℃ and 60℃ for 10 min.

Isolates isolated from maize and 3 isolates from rice, wheat, adzuki bean in ten provinces were identified as Curvularia lunata. Based on the culture characters, such as color of colony, aerial myeelia, the number of conidia, there were some difference among 43 isolates. Meanwhile, five types of conidium were compared in culture characters and virulence. In each single conidia culture there were different morphic conidia also and no difference in virulence was found among five single-conidium cultures.

收集并分离我国10个省的玉米叶斑病病原物40个以及水稻、小麦、红小豆上的C.lunata分离物3个；对分离物进行培养性状、产孢能力及形态特征的研究结果表明：分离物在菌落颜色、气生菌丝的繁茂程度、产孢量的多少等方面存在明显的差异；同一分离物内分生孢子在形态方面有差异，不同形态单孢继代培养后仍出现多种形态分生孢子，但各单孢培养系在致病力上无差异。

Reported diseases include crown gall, bacterial wilt, little-leaf, seedling blight, angular leaf spot, leaf spot, brown spot, leaf rust, grey mold, shoot blight, stem canker, and butt rot. Several non-infectious diseases including the leaf red spot, gummosis, herbicide in jury, typhoon damage and genetic albinism and an unidentified leaf crinkle disease are also described.

报告之桉树病害包括癌肿病、青枯病及小叶病等细菌注病害；苗腐病、角斑病、叶斑病、玫瑰桉叶斑病、叶锈病、灰霉病、褐斑病、枝枯病、溃疡病及冠腐病等真菌性病害；此外非病原性病害包括红斑病、流胶病、除草剂药害、风害及遗传性白化症等，以及病因不明之尾叶桉皱叶病亦在文内叙述之。

Therefore, Alternaria is the main pathogen of cotton leaf spot. 2. Pathogenicity test of the above-mentioned 26 strains showed that they are the cotton leaf spot pathogens as the eumycetes isolated from the Invasived plants are the same with the pathogenetic strains.

根据科赫氏法则从接种发病植株叶片上分离病菌，其形态特征与从自然发病植株上分离的相同，证实这些菌株就是棉花叶斑病的致病菌，其中链格孢属是棉花叶斑病的主要致病菌属 3。

In this study, used Multiplex-PCR method to detection AAC of AAC_ITS and AAC_rpoB, used Multiplex-PCR method to detection BG of BG_ITS、BG_gyrB and BG_rpoD, used Multiplex-PCR method to detection PCH of PEC_ITS, idgA and idgB, used Multiplex-PCR method to detection AAC、BG and PCH of AAC_ITS、BG_ITS、PEC_ITS and idgA. The result reveals which were designed primer of specific can detect the existence of different phytopathogenic bacteria. These technique will use to develop the standard operation procedure of phytopathogenic bacteria disease in orchids.

在多引子组之研究上，AAC_ITS及AAC_rpoB之组合可用於褐斑病菌之检测；BG_ITS、BG_gyrB及BG_rpoD之组合可用於叶斑病菌之检测； PEC_ITS、idgA及idgB之组合可用於软腐病菌之检测；AAC_ITS、BG_ITS、PEC_ITS和idgA之组合则可用於三种兰花细菌性病原之检测，分析结果显示所使用之引子组可以快速、灵敏且专一性的检测细菌性褐斑病、细菌性叶斑病及细菌性软腐病，并且缩短检测时间，未来将可以应用於兰花细菌病害之监测。

An added benefit of high density plantain cultivation is a lower incidence of yellow sigatoka and black sigatoka two of the most important diseases that affect plantain.
