筛选、验证自行研制的种衣剂LDS 1～ 5号在田间对玉米丝黑穗病的实际防效 ,为种衣剂LDS的进一步研究、完善、定型及试验示范与推广提供试验依据 ,并与国内 4种商品种衣剂对玉米丝黑穗病防治进行了田间药效比较。结果表明 ,种衣剂LDS有着很好的防效 ,尤其是种衣剂LDS4和LDS 5更为突出 ,防效高达 81.5 3%和 85 .6 0 % ,明显高于对照和其它各处理的防效 ;种衣剂LDS 4和LDS 5处理的产量最高 ,分别为 4 95 6 .2 3kg/hm2 和 5 0 2 2 .0 0kg/hm2 ,比对照增产 2 3.2 5 %和 2 4 88% ,因此LDS 4和LDS 5是防治玉米丝黑穗病较理想的种衣剂
Screening and validating the actual control efficacy of self-developed seed coating agent LDS 1-5 on maize head smut in the field, providing experimental basis for further research, perfection, finalization, demonstration and promotion of seed coating agent LDS The domestic four kinds of commercial seed coating agent on maize head smut prevention field efficacy comparison. The results showed that the LDS seed coating has a very good control effect, especially the seed coating agents LDS4 and LDS 5 are more prominent, the control efficiency of up to 81.5 3% and 85.60%, significantly higher than the control and other treatments The yields of the seed dressing LDS 4 and LDS 5 were the highest, which were 495.223kg / hm2 and 52.02kg / hm2, respectively, which increased by 23.2% and 24.8% respectively compared with the control LDS 4 and LDS 5 are the ideal seed coating for controlling corn head smut
