稻瘟病(Pyricu’aria oryzae)是水稻主要病害之一,严重影响水稻高产稳产。目前,防治稻瘟病的有效药剂常常不能适应农业生产的需求,稻瘟病菌又易产生抗药性,稻瘟净、富士一号等的防治效果已欠佳,因而寻找新农药仍有必要。 1989年我们承担了全国大田药效试验网提供的广东省江门市农药厂以三环唑加硫磺生产的复合新剂型—45％瘟特灵胶悬剂防治叶瘟和穗瘟的小区试验,防治效果很好。 由于穗瘟对水稻产量影响较大,1991年
Pyricularia oryzae is one of the major diseases of rice and seriously affects the high and stable yield of rice. At present, the effective medicament for preventing and controlling rice blast often can not meet the needs of agricultural production, and the susceptible strains of Magnaporthe grisea are easy to produce. The control effect of such as rice blast and net of Fuji-1 has been poor, so it is still necessary to find new pesticides. In 1989, we undertook the plot test of prevention and cure of leaf plague and panicle blast by the compound new formulation of tricyclazoline plus 45% plastine suspension provided by Jiangmen Pesticide Factory in Guangdong Province. good results. Because of the impact of head blast on rice yield greater, 1991
