摘要
选用30%恶霉灵·精甲霜灵135 g/hm^2,30%恶霉灵·精甲霜灵202.5 g/hm^2,30%恶霉灵·精甲霜灵270 g/hm^2,350 g/L精甲霜灵乳剂1800 g/hm^2,70%恶霉灵可湿性粉剂9000 g/hm^2,70%丙森锌可湿性粉剂2100 g/hm^2进行辣椒猝倒病的药效对比试验。试验结果表明30%恶霉灵·精甲霜灵270 g/hm^2防效最高,达到79.1%,30%恶霉灵·精甲霜灵202.5 g/hm^2、350 g/L精甲霜灵乳剂1800 g/hm^2和70%丙森锌可湿性粉剂2100 g/hm^2,效果也较好,分别达到66.7%、62.5%和62%。建议辣椒播种前2 d,选用30%恶霉灵·精甲霜灵135 g/hm^2及以上用量进行苗床浇灌。
135 g/hm^2, 202.5 g/hm^2 and 270 g/hm^2 of Hymexazol＋Metalaxyl-M 30 %SL, 1800 g/ha of 350 g/L Metalaxyl-M EC, 9000 g/hm^2 of Hymexazol 70 % WP and 2100 g/hm^2 a of Propineb 70 % WP are chosen for the experimental comparision on the capsicum damping-off disease. The test results indicate that, the controlling efficacy of Hymexazol＋Metalaxyl-M 30 %SL at dosage of 270 g/hm^2 is best, up to 79.1%, and the controlling efficacy of Hymexazol＋Metalaxyl-M 30 % SL at dosage of 202.5 g/ha, Metalaxyl-M 350 g/L EC at dosage of 1800 g/hm^2 and 70 % Propineb WP at 2100 g/hm^2 is 66.7 %, 62.5 % and 62 % respectively. The recommended usage is that, 2 days before the sowing of the chilies, use Hymexazol＋Metalaxyl-M 30 %SL at dosage of 135 g/hm^2 or at higher dosage for the seedbed irrigation.
