摘要
分别用 25%甲霜灵种衣剂,35%多克福种衣剂和 58%雷米多尔 WP 处理大豆种子,田间试验防治大豆疫霉根腐病效果如下:人工接种试验小区用药量 2%,防治效果 90%,并且甲霜灵防治疫霉根腐病的效果直到开花之前;未接种试验小区用药量 1%,防病效果 70%～78.1%;三个农场较大面积试验,防病效果 72.3%～82.3%,对照药剂为 35%多克福种衣剂。大面积应用甲霜灵种衣剂,大豆产量比 35%多克福种衣剂平均增产 16.2%。
Soybean seed was coated with 25% Metalaxyl and 35% Carbendzim-Carbofurum-Thiuram seed coating and 58% Ridomil WP. respectively. The control effect of polt treat by artificial inoculation in 2% Metalaxyl seed coating was 90.0%, and the control effect of Metalaxyl seed coating in phytophthora root rot had before until stage of flower. The control effect latural field treat showed 70%～78.1%,and in three farms larger field treat showed 72.3%～82.3% comparing with 35% Carhendazim-Carbofurum- Thiuram seed coating. The result of large field treat were added 16.1% of average yield of soybean under use 25% Metalaxyl seed coating than the 35% Carhendazim-Carbofurum-Thiuram seed coating.
