水稻纹枯病俗称烂脚杆,在世界各地种植水稻的地区普遍发生。水稻纹枯病一旦发生,会造成叶片枯死、结实率下降,甚至植株全部枯死。目前,防治水稻纹枯病的主要措施仍是以农业防治为基础、化学防治为主。但是,一种药剂长期使用会造成防效下降或导致病原菌产生抗药性。因此,需要进行水稻纹枯病防治新措施以及新药剂的研发和储备。笔者在此方面做了一些试验,现将试验结果总结如下。
Rice sheath blight, commonly known as rotten foot, is common in areas where rice is grown all over the world. Once rice sheath blight occurs, it will cause the leaves to die, the seed setting rate will drop, and even the plants will all die. At present, the main measures to prevent and control rice sheath blight are still based on agricultural control and chemical control. However, the long-term use of a pharmaceutical agent can result in a decrease in control efficacy or lead to the development of resistance by pathogens. Therefore, new measures for prevention and control of rice sheath blight and research and development and reserve of new medicaments are needed. I made some tests in this area, the test results are summarized below.
