棉花枯萎病是棉花的重要病害。我省发病轻的病株率1-2％;较感病品种辛541、徐514、中7、辽7等病株率为10-18.6％;辽7连作4年后病株率高达32.8％。为控制蔓延危害,1985-1986年进行了农用抗菌素“120”药液灌根防治试验,效果良好。用2％农抗“120”(江苏宜兴生物药厂生产)和3％农抗“120”(湖北生物药物厂生产),在6月上、中旬棉花枯萎病发生初期灌根防治棉枯萎病。从表1、2看出,100、60单位农抗“120”灌根10天后,
Cotton Fusarium wilt is an important disease of cotton. In our province, the incidence rate of mild disease was 1-2%; the susceptible strain Xin 541, Xu 514, Zhong 7, Liao 7 and other strains were 10-18.6%; the rate of diseased plants was as high as 32.8% . To control the spread of harm, 1985-1986 agricultural antibacterial “120” liquid irrigation control experiment, with good results. The cotton fusarium wilt was drenched with 2% agronomic “120” (produced by Jiangsu Yixing Biopharmaceutical Factory) and 3% agronomic “120” (produced by Hubei Biopharmaceutical Factory) in the early and middle of June. It can be seen from Table 1 and Table 2 that after 10 days of rooting with 100 and 60 units of “120”
