金捕隆等6种药剂拌种防治向日葵白锈病试验结果表明:金捕隆等6种药剂拌种后对向日葵出苗安全,不产生药害。从防效上看,随着向日葵生育进程的推进,金捕隆等6种药剂的防效均呈下降趋势。药效期为两个月,出苗70天后,药效下降显著。从向日葵生育进程上看,拌种在苗期药效较为理想,此期25%甲霜灵WP,每100kg向日葵种子用35%金捕隆悬浮种衣剂200ml,每100kg向日葵种子用35%金捕隆悬浮种衣剂300ml和64%杀毒矾WP的药效较好;显著高于50%安克WG;52.5%抑快净WG的防效最低。经方差分析证明处理间差异达到显著水平。
Jinchanlong 6 kinds of pharmaceutical seed dressing sunflower white rust test results show that: Jinchanlong 6 kinds of agents after the seed dressing on the sunflower safe, does not produce phytotoxicity. From the perspective of prevention and control, with the advancement of the growth of sunflower, the anti-efficacy of six drugs such as Jinchao Long showed a downward trend. Shelf life of two months, 70 days after emergence, significant decline in efficacy. From the sunflower growth process point of view, the seed dressing efficacy is more ideal seed dressing, this period 25% metalaxyl WP, 35% gold per 100kg of sunflower seedlings suspended sediment suspension 200ml, 100kg sunflower seeds with 35% gold The efficacy of the catch-suspended suspended coating agent 300ml and 64% antiviral WP was better; significantly higher than 50% Anker WG; and the control effect of 52.5% fast-clearing WG was the lowest. Analysis of variance showed that the difference between treatments reached significant level.
