近年来,水稻纹枯病危害日趋严重,是影响水稻高产的主要因素之一。田间调查结果表明,用井岗霉素防治水稻纹枯病,效果较好。据我站试验,一般年份应在7月10～15日进行第一次防治,此时水稻已进入减数分裂期。12～15天后,当水稻出穗时,再进行第二次防治。每次每亩用2两5％井岗霉素,加水100斤向水稻茎基部喷雾。如用0.7毫 In recent years, the threat of sheath blight is becoming more and more serious, which is one of the main factors affecting the high yield of rice. Field survey results show that with Jinggangmycin to control rice sheath blight, the effect is better. According to my station test, the general year should be the first control from July 10 to 15, when rice has entered meiosis. After 12 to 15 days, when the rice leaves out, carry on the second control. Each two acres with 2 5% Jinggangmycin, add 100 pounds of water to the base of rice stem spray. If using 0.7 milliliters
