1980—1982年在本校和洮儿河农场分别用6种新农药对小麦散黑穗病进行了小区和较大面积的防治示范试验,结果以禾穗胺效果最好,用0,3％拌种3年小区平均防效为95％(92.55—100％),较大面积示范试验为95,28％,其次是拌种双,2年小区平均防效为86,03(79,36—92,70％)。多菌灵、粉锈宁防效亦好,依次为(84,94％、83,83％)。在体外抑菌试验中禾穗胺在低浓度下即对小麦散黑穗病菌冬孢子发芽和病菌菌落生长就有强烈抑止作用,而粉锈宁、多菌灵则需较高浓度。幼芽期药剂内吸测定禾穗胺的内吸量较高。 禾穗胺、拌种双用不同方式(干拌、湿拌、浸种、闷种)进行种子处理对防效影响差异不显著。禾穗胺、粉锈宁在拌种后贮藏15—60天均无增效作用。
From 1980 to 1982, six kinds of new pesticides were used in our school and Tong’er River farm respectively to carry out demonstration experiments on the prevention and treatment of scattered smut in small plot and large area. The results showed that the best effect was Wooshuamine, with 0,3% The average control effect in three years was 95% (92.55-100%), 95% and 28% for large-scale demonstration experiments, followed by the double-seed dressing. The average control effect of two years was 86,03 (79,36-92 , 70%). Carbendazim, triadimefon also control effect, followed by (84,94%, 83,83%). In vitro antibacterial test Wooshu amine at low concentrations that wheat spore germination of Trichosporon spores and bacteria colonies have a strong inhibitory effect, and the prostaglandin, carbendazim need higher concentrations. Sprouting drug determination of spike absorption within the higher spike amine. Wo spike amine, seed dressing with two different ways (dry mix, wet mix, soaking species, boring species) seed treatment on the control effect was not significantly different. Wo spike amine, triadimefon in the seed dressing after 15-60 days no synergistic effect.
