福·克种衣剂对玉米和靶标病虫害的影响

Effects of Two Seed Coating Agents on Maize and the Target Diseases and Pests

通过田间试验的方法,研究了福·克种衣剂对玉米品种郑单958的安全性及其靶标病虫害的影响。结果表明,20%福·克种衣剂和16%克·醇·福美双种衣剂对玉米的出苗和生长有一定的促进作用,并显著增加了玉米的出苗率,对玉米苗期的各项生长指标表现出一定的促进作用。20%福·克和16%克·醇·福美双在玉米苗期对地下害虫有防治效果,但对后期的玉米螟(Ostrinia furnicalis)、玉米顶腐病(Fusarium subglutinans)和玉米黑穗病(Spirisorium reiliana)没有防治效果,尤其在收获期玉米螟有加重趋势。种衣剂的使用提高了产量、玉米穗长和穗粒重等产量及其构成指标,但与对照相比无显著差异。

The safety of two seed coating agents to maize Zheng Dan 958 and their impact on target diseases and pests of maize were studied in the fields.The results showed that Thiram-Carbofuran(20%)and Thiram-Carbofuran-Triadimefon(16%)can promote the seeding emergence and growth of maize,they increased the rate of emergence significantly and the growth indicators of maize seedling also showed increasing.Thiram-Carbofuran(20%)and Thiram-Carbofuran-Triadimefon(16%)have control efficacy on underground pests in maize seedling stage,but reveal no control efficacy on Ostrinia furnicalis,corn crown rot and smut at the growing periods,especially the damage of corn borer trends to increasing in the harvest.The seed coating agents increased maize spike length and spike grain weight,but the differences between the treated and controlled area have no significance.
