Popis: | Rice is the most important food crop and directly feeding more people than any other crop in the world.The blast disease caused by Pyricularia oryzae is a major and foremost constraint in rice production.Use of tricyclazole fungicide is one of the best and cost effective ways to quickly manage the disease. Considering the extensive use of fungicide has adverse effects for environment, the present study has been conducted to know the effect of Tricyclazole and Pseudomonas fluorescens alone and various combinations during rabi 2015-2016 and 2016-2017. From the two years data, the results indicated that a spray schedule consisting of tricyclazole followed by an alternate spray of Pseudomonas fluorescens (T + P + T + P), as well as either seed treatment with tricyclazole at 0.1 percent or root dipping with P. fluorescens at 1%, effectively reduced both leaf blast and neck blast with increasing grain yield. |
