摘要： 为筛选甘蔗凤梨病防治药剂，寻求最佳使用技术方法，结合新植蔗下种，采用蔗种单芽包衣、双芽包衣、双芽浸种等3种方式对28.7%精甲霜灵·咯菌腈·噻虫嗪FS防治甘蔗凤梨病效果进行田间评价。结果表明，28.7%精甲霜灵·咯菌腈·噻虫嗪FS蔗种双芽包衣和双芽浸种2种处理都能有效防治甘蔗凤梨病。28.7%精甲霜灵·咯菌腈·噻虫嗪FS 942~1605 mL/hm2蔗种双芽包衣防效为58.69%~61.20%、28.7%精甲霜灵·咯菌腈·噻虫嗪FS 1000~1500倍液蔗种双芽浸种处理防效为51.51%~54.70%，明显优于对照农药50%多菌灵WP，且对甘蔗安全。甘蔗凤梨病高发区，可结合当地甘蔗生产实际，于甘蔗下种期，采用28.7%精甲霜灵·咯菌腈·噻虫嗪FS防治甘蔗凤梨病，蔗种包衣处理剂量以942 mL/hm2为宜，蔗种浸种处理药液浓度以1500倍为宜。

Abstract: Three treating methods, single-eyed sett coating, two-eyed sett coating and two-eyed sett soaking, combined with seed cane planting were applied to evaluate the control effects of 28.7% Metalaxyl- M·fludioxonil·thiamethoxam FS pineapple disease in sugarcane. The results showed that both two- eyed sett coating and two- eyed sett soaking of 28.7% Metalaxyl- M·fludioxonil·thiamethoxam FS could effectively control pineapple disease of sugarcane. The control effects of 28.7% Metalaxyl-M·fludioxonil·thiamethoxam FS two- eyed sett coating with treating doses of 942- 1605 mL/hm2 and 28.7% Metalaxyl- M·fludioxonil·thiamethoxam FS two-eyed sett soaking with treating doses of 1000-1500 fold solutions were 58.69%-61.20% and 51.51%-54.70% respectively, which were significantly superior to the effect of the control fungicide 50% carbendazim WP. The observation also suggested that 28.7% Metalaxyl-M·fludioxonil·thiamethoxam FS was safe to sugarcane. In cane- growing regions with high incidence rate of pineapple disease, based on the production practice, it could select 28.7% Metalaxyl-M·fludioxonil·thiamethoxam FS two-eyed sett coating with treating dose of 942 mL/hm2 or 28.7% Metalaxyl-M·fludioxonil·thiamethoxam FS two-eyed sett soaking with treating dose of 1500 fold solution to effectively control pineapple disease.
