用赛力散等有机汞剂拌种防治小麦秆黑粉病效果不好,不能满足生产上要求。作者等从1957年至1959年曾在温室及田间进行了有关六氯代苯防治小麦秆黑粉病的浓度、用量、施用方法等问题的研究。结果证明用0.3%六氯代苯(有效含量40—60%)拌种对土壤传染的秆黑粉病有60—70%的防治效果,拌种结合土壤施药(每亩用有效含量为40%的六氯代苯1—2厅)防治效果可达90%左右。部分研究结果已在有关杂志上发表,上述防治方法已在生产上开始推广应用。本文系尚未发表的主要研究结果的较系统的报导。
With Saracenic and other organic mercury agent seed dressing prevention and control of wheat stalk powdery mildew is not good, can not meet the production requirements. The author from 1957 to 1959 in the greenhouse and fields were carried out on hexachlorobenzene prevention and treatment of wheat stem powdery mildew disease concentration, dosage, application methods and other issues. The results showed that 60% -70% control effect on soil-borne stalk powdery mildew was found when dressing with 0.3% hexachlorobenzene (effective content 40-60%), and dressing and soil application (the effective content per mu was 40 % Hexachlorobenzene 1-2 Hall) control effect of up to 90%. Some of the research results have been published in the relevant magazines, the prevention and control methods have been started to promote the use of production. This article is a systematic report of unpublished major findings.
