不同药剂处理对栾树枯萎病的防控效果

Control Effect of Different Reagents on the Fusarium Wilt of Koelreuteria paniculata

为有效预防栾树枯萎病爆发,本研究筛选出3种对栾树枯萎病有较好预防效果的药剂,采用4种不同处理方式对栾树枯萎病预防效果开展评估测定。结果表明:申嗪霉素对栾树枯萎病预防效果最佳,预防效果可达到77.78%,且生长量整体稳定,不良影响最小;其次为木霉菌浇水处理,预防效果为57.14%,植株生长量稍低于申嗪霉素;使用木霉菌未浇水和代森锰锌灌根处理组预防效果较差,且植株生长量降低。

In order to prevent Fusarium wilt of Koelreuteria paniculata ,three relatively good medicament were selected and four treatments were used for measurement.The results indicated that deuteromycin had good prevent effect with 77.78% control efficiency while had not harmful effect. Trichoderma spp. with water had 57.14% control efficiency and had little harmful effect. Trichoderma spp without water and mancozeb had bad effect and big harmful effect.
