近几年来,水稻稻曲病危害日益加重,从而受到农业科技部门关注。分析其主要因素为水稻品种更新、耕作制度改变和施肥水平提高,逐步使稻曲病成为水稻主要病害,不仅影响产量、降低米质,同时稻曲病米粒及米糠对人畜有毒性。虽然选用抗疫品种、科学合理施肥,有利于减轻稻曲病的危害,而掌握施药适期及时使用农药防治,仍是有效控制稻曲病危害的重要措施,从而登记防治稻曲病的产品相应扩展。稻曲病危害加重后,为相关杀菌剂品种扩大了市场容量。据统计至今 In recent years, the harm of rice false smut is aggravating day by day, which is of concern to agricultural science and technology departments. Analysis of its main factors for the update of rice varieties, farming system changes and fertilization levels, and gradually make rice false smut become the main disease in rice, not only affect the yield, reduce the quality of rice, rice and rice bran rice bran and rice is toxic to humans and animals. Although the selection of anti-epidemic species, scientific and rational fertilization is conducive to mitigate the hazards of false smut, and grasp the timely and timely application of pesticides pesticide control is still an important measure to effectively control the damage of false smut, thus registering the control of smut Expanded accordingly. After the increased risk of false smut, the market size of relevant microbicides has been expanded. According to statistics so far
