用化学方法防治棉枯黄萎病是目前生产上的一重大难题。前人采用喷雾、涂茎和灌根等方法治疗,防效仅50%左右。1986年推广中发现三唑酮根区注射对棉枯萎病的防效为88.5～92.6%。为进一步证实三唑酮根区注射防治棉枯黄萎病的效果和筛选出新的药剂或配方,特进行如下室内毒力试验。现报道如下。 Chemical methods to prevent and control cotton wilt are currently a major problem in production. Past use of spray, stems and irrigation methods such as irrigation, anti-effect is only about 50%. In 1986, it was found that the control effect of triadimefon at the rate of 88.5-92.6% on Fusarium oxysporum f. In order to further confirm the effect of triazophone root zone injection against Verticillium dahliae and screen out new agents or formulations, the following indoor toxicity test was conducted. Report as follows now.
