为明确泡核桃干腐病的病原和筛选合适的化学防治药剂,云南农业大学、云南省林业科学院科研人员从云南省楚雄州大姚县核桃病害标本中分离和鉴定了病原菌,并测定了8种杀菌剂对其的毒力。研究人员通过柯赫氏法则验证,确定分离得到的该菌株能侵染泡核桃,产生干腐症状。依据形态特征和rDNA-ITS序列分析,将病原鉴定为茶藨
In order to clarify the pathogen of dry walnut walnut disease and to screen for suitable chemical control agents, researchers from Yunnan Agricultural University and Yunnan Academy of Forestry isolated and identified the pathogenic bacteria from walnut disease specimens in Dayao County, Chuxiong Prefecture, Yunnan Province. Fungicide on its virulence. The researchers through the Koch’s rule validation, to determine the isolated strain can infect walnut, resulting in dry rot symptoms. Based on morphological characteristics and rDNA-ITS sequence analysis, the pathogen was identified as Chardin
