【摘要】 试验证明,抗生素16A-6对水稻白叶枯病的防效优于叶枯净、叶枯宁、略次于敌枯双,增产效果为最高,一般防效在70％左右,高的可达90％以上。增产效果一般为10—20％。还发现喷药后不久遇雨,效果仍然很好。在1980和1983年防治示范中,被洪水淹过的稻田,病害发生已重,仍收到了良好的防效。更多还原

【Abstract】 The results of field experiments proved that the control effect of antibiotic 16A-6 to the Xanthomonas campestris pv. oryzae of rice was supperior to that of YEKUJING and CHUANHUA-018, but lightly lower than that of DIKUSHUANG in reduction of disease incidence and increase of yield. In general its control effect was about 70%, and in some cases might be over 90%. The yield increase in average was 10-20%. 16A-6 showed good control effeot when it rained soon after spray and even after sprayed rice fields suffred floods in 1980 and 1983.更多还原
