采用毒土法施药,比较了8种药剂对白菜种子出芽率的影响及对温室苗期盆栽白菜根肿病的防治效果。结果表明,100 g/L氰霜唑SC、50%氟啶胺SC、50%多菌灵WP、68%精甲霜·锰锌WG防治白菜根肿病效果较好。其中,以100g/L氰霜唑SC 100 g/m3处理的防效最好,出芽率、防效均达90%以上;50%氟啶胺SC 312.5 g/m3和50%多菌灵WP250 g/m3效果较好,出芽率、防效达80%以上。68%精甲霜·锰锌WG 937.5 g/m3防效接近80%,出芽率受到轻微影响。
The poisonous soil was applied to control the germination rate of cabbage seeds and the control effect on the cabbage clubroot disease in greenhouse seedlings. The results showed that 100 g / L cyazofamid SC, 50% fluazinam SC, 50% carbendazim WP and 68% dextromethorphan Mn-Zn WG were effective in controlling clubroot disease. Among them, the control effect of 100g / L cyazofamid SC 100g / m3 was the best, the germination rate and the control efficiency reached more than 90%; 50% fluazinam SC 312.5g / m3 and 50% carbendazim WP250g / m3 better effect, budding rate, control effect of more than 80%. 68% fine cream · manganese zinc WG 937.5 g / m3 control effect of nearly 80%, budding rate slightly affected.
