我县1965年发生过细菌性条斑病,由于当时采用封锁.消灭菌源措施,发生危害得到控制。近年来,随着品种调运日益频繁,加上检疫制度不够健全,1987年本病又传入我县,全县共有3个乡14个村的2661亩稻田发生了细条病,到1989年发生面积达9200亩。根据我站观察测定,本病的危害程度随受害叶面积的增加而增加,结实率比正常水稻下降5.6～20.3%,千粒重下降0.1～4.8克。细条病的防治首先要加强检疫工作,在病区设法封锁和消灭菌源,1988～1989年我县营前乡采取禁止在病区制种、留种,病草集中烧毁,病田用石灰静水消毒15天,病害得到控 Bacterial bar leaf streak occurred in 1965 in our county, because the blockade was used at that time, and the eradication of bacterial source measures was put under control. In recent years, with the increasingly frequent adjustment of species, coupled with the quarantine system is not sound enough, in 1987 the disease was introduced to my county, the county a total of 3 townships 14 villages 2661 acres of paddy rice stripe disease occurred in 1989 area Up to 9200 acres. According to the observation of our station, the degree of harm of this disease increased with the increase of the affected leaf area. The seed setting rate was 5.6 ~ 20.3% lower than that of normal rice and 0.1 ~ 4.8 g weight of 1000-grain weight. Prevention and control of thin-walled diseases should first of all be strengthened quarantine work, try to blockade and eradicate bacteria in the ward, 1988 ~ 1989 Camp County precincts banned in the ward seed, remaining species, sick grass concentration burned, disease with lime hydrostatic Disinfection for 15 days, disease control
