莎多伏防治移栽和直播稻田杂草试验效果初报

Preliminary Study on the Effect of Applying Cinosulfuron to Control Weed in Direct-seeded and Transplanted Rice Field

通过田间试验表明莎多伏对水稻移栽田和直播稻田阔叶杂草防除效果显著,对日本藨草有明显的抑制作用,使用剂量以150g/hm2为宜、同时明确了莎多伏的施用时期、施药方法以及对水稻的安全性。为莎多伏的推广应用提供了依据。

The result of the field trail indicated that Cinosulfuron was an excellent herbicide to control the broad leaf weed in direct-seeded and transplantod rice field. It has good effect to control the Scirpus nipponicum and the suitable usage was 150g/hm^2. Application time and method and the safety of the cinosulfuron to rice were also discussed in the paper, which provide good evidence of applying cinosulfuron properly.
