系统总结福建省水稻白叶枯病和细菌性条斑病的发生流行、分布为害、病区划分及防治对策,并比较其异同。白叶枯病主要发生在60~70年代;细条病则以80~90年代为主。品种抗性、菌源多寡、气候是否适宜,是决定病害流行的重要条件。病原菌蛋白质图谱测定,其相似系数越大的菌株致病性越相近。菌源除稻种、稻草、稻桩外,还存在于杂草寄主,白叶枯病菌的杂草寄主种类比细条病菌的多。常规稻抗白叶枯病的品种,一般也抗细条病;杂交稻抗白叶枯病的组合,一般不抗细条病。在药剂防治上,新农药乙霜青,对细条病药效较好,对白叶枯病效果较差。两病防治均以推广抗病品种为中心,杜绝菌源为基础,结合健稻栽培和及时药剂保护的综防控病为上策。
The prevalence and distribution of bacterial leafbelt and bacterial leafbelt in Fujian Province were systematically summarized, and the division and prevention and treatment of wards were compared. Bacterial blight occurs mainly in the 60 ~ 70s; thin strip disease is dominated by 80 ~ 90s. Variety resistance, the amount of bacteria, the climate is appropriate, is an important condition to determine the epidemic. Pathogen protein profile determination, the greater the similarity coefficient of the more pathogenic strains closer. In addition to the source of rice, rice straw, rice piles, but also in the weed host, bacterial blight bacterial weed host species than the number of bacteria more. Conventional rice varieties resistant to bacterial blight, generally also resistant to thin sliver; combination of bacterial blight resistance in hybrid rice, generally not resistant to thin strip disease. In the prevention and treatment of pesticides, the new pesticide B cream, the slips of the better efficacy of bacterial blight less effective. Prevention and treatment of both diseases are to promote disease-resistant varieties as the center, to eliminate the source of bacteria, combined with healthy rice cultivation and timely protection of comprehensive prevention and control disease is the best policy.
