两种药剂对水稻细菌性条斑病的防治效果研究

Study on the Control Effect of Two Chemicals on Bacterial Leaf Spot of Rice

【目的】验证碧生(20%噻唑锌悬浮剂)对水稻细菌性条斑病的防治效果。【方法】将碧生与当地种植户常使用的辛菌胺醋酸盐细菌剂的方法进行对比,在湛江市文竹村选择近3年发病较重的水稻田开展相关试验。【结果】使用碧生和辛菌胺醋酸盐细菌剂分别在水稻封行期、分蘖末期、破口期进行施药试验,其中使用碧生对水稻细菌性条斑病的防治效果比辛菌胺醋酸盐细菌剂的更好,防效可达63.28%,且处理后水稻产量(干重)最高,为577 kg,同时还能提高水稻产量和有效控制细条病的蔓延。【结论】浙江新农化工股份有限公司自主研发的碧生(20%噻唑锌悬浮剂)可广泛应用于防治细菌性病害,如水稻细菌性条斑病,从作物苗期开始,整个生育期都可用药,具有很高的安全性且效果非常理想。

[Objective] To verify the control effect of bisheng(20% zinc thiazole suspension) on bacterial leaf spot of rice. [Method]By comparing the method of bisheng with the method of octrimonamide acetate bacterial agent commonly used by local growers,relevant experiments were carried out in the paddy field with serious disease in the past three years in Wenzhu Village, Zhanjiang City. [Result] The application test was carried out with bisheng and octrimonamide acetate bacterial agent at the closing stage,the end of tillering and the breaking stage of rice. The control effect of bisheng on rice bacterial stripe disease was better than that of octrimonamide acetate bacterial agent, the control effect was up to 63.28%, and the rice yield(dry weight) after treatment was the highest, which is 577 kg. At the same time, it could also improve the rice yield and effectively control the spread of fine strip disease. [Conclusion] Bisheng(20% zinc thiazole suspension agent) independently developed by Zhejiang Xinnong Chemical Co.,Ltd. can be widely used to control bacterial diseases, such as bacterial stripe disease of rice. It can be used from the seedling stage to the whole growth period of crops, with good safety and very ideal effect.
