Bio-efficacy of amisulbrom 20% SC (Kirari) against Late blight disease (Phytophthora infestans) of potato under West Bengal condition
Author(s): A Chakraborty and S Murmu
Abstract: The experiment was conducted with new molecule fungicide Amisulbrom 20% SC (Kirari) against late blight of potato and its phytotoxicity for two crop seasons i.e.2013-14 and 2014-15.The test fungicides at 500 ml/ha exhibited highest disease controlling ability in terms of percent incidence and percent disease intensity as compared to other available fungicides and control treatment. The percent disease incidence and intensity were 15.35 and 15.10 and 10.10 and 11.45% respectively during 2013-14 and 2014-15 crop season as compared to control treatment where percent disease incidence and intensity were 92.10 and 94.67 and 16.25 and 18.25% respectively. The test fungicides also proved its efficacy at lower dose also. The test fungicide amisulbrom 20% sc @ 500 ml/ha exhibited higher yield (30.25 and 32.50 t/ha) in both the crop season i.e. 2013-14 and 2014-15. Therefore amisulbrom 20% sc @ 500 ml/ha can be employed in the management of late blight of potato.
