用不同的杀菌剂复配后包衣玉米种子进行玉米种子出苗安全性及防治主要病害(玉米丝黑穗病)的田间试验并测定其对产量的影响。结果表明:在接种玉米丝黑穗病菌的地块,不同剂量种衣剂复配处理不但对玉米的出苗安全性没有降低反而略有增加。从对玉米种子的安全性、病害防治效果、产量等综合因素上分析,处理A-3(顶苗新400+高巧200+EV302成膜剂200)表现的效果最佳;从安全性、防治效果和经济成本等方面考虑,处理A-6、A-7较理想。
Field experiments on the safety of emergence of maize seeds and the control of maize head smut (Maize head smut) were performed with different bactericides and coated with coated corn seeds to determine their effects on the yield. The results showed that in the inoculation of maize head smut bacteria plots, different doses of seed coating compound treatment not only did not reduce the emergence of corn safety but increased slightly. From the analysis of the comprehensive factors such as the safety of corn seeds, disease prevention and control, yield and so on, the effect of A-3 (Dingmiaoxin 400 + Gaoqiao 200 + EV302 film-forming agent 200) Effects and economic costs and other considerations, to deal with A-6, A-7 is more desirable.
