麦类作物通过种子传染的病害很多,如散黑穗病、腥黑穗病、大麦条纹病、赤霉病等。麦类作物传统的种子消毒方法是温汤浸种和有机汞制剂处理。本试验研究了各种新的种子消毒剂对各种麦类病害的防治效果和使用方法。 (1)大麦散黑穗病:迄今,除了温汤浸种法外,没有适合的种子消毒法,作者试验用苯菌双可湿性剂(苯菌灵和福美双的混合剂)按种子干重0.3～1.0％的药量拌种,或用该剂20倍液浸种10分钟,100倍液浸种3小时,200 Malting crops through the seeds of many diseases, such as casual smut, fish disease, barley stripe disease, scab and so on. The traditional method of seed disinfection of wheat crops is the soaking of warm soups and the treatment of organic mercury preparations. This experiment studied various new seed disinfectants on the prevention and treatment of various wheat diseases and methods of use. (1) Barley smut: So far, there is no suitable method of seed disinfection except for the soaking method of warm broth. The test was conducted by using benomyl double wettabler (mixture of benomyl and thiram) at 0.3 ~ 1.0% of the dose of seed dressing, or soaking the agent 20 times for 10 minutes, soaking 100 times for 3 hours, 200
