EVALUATION AND STANDARDIZATION OF FUNGICIDES AGAINST PLANT DISEASES IN PUNJAB-PAKISTAN CROP PRODUCTION SYSTEM.

Present study was conducted at Plant Pathology Research Institute, AARI, Faisalabad, Punjab, Pakistan during 2001 to 2013, for evaluating and standardizing 168 fungicides against 28 different plants diseases on 15 various crops. The experiment was laid out in RCBD with two replications. Maximum percentage of fungicides were standardized against diseases of vegetables (69.64%) followed by fruit plants (16.07%) and field crops (14.29%). Maximum fungicides standardization percentage was recorded against potato diseases (30.36%) followed by muskmelon (18.45%), mango (12.50%), tomato (10.12%), rice (8.93%) and cucumber (6.55%). Maximum percentage of fungicides were standardized against potato late blight (26.19%), followed by muskmelon downy mildew (15.48%), mango powdery mildew (9.52%), tomato late blight (7.14%), cucumber downy mildew (5.36%) and rice blast (5.36%). All the fungicides standardized against the crop diseases, effectively controlled the maladies when used at their recommended doses. In general, all the fungicide treatments significantly reduced the disease incidence resulting in higher crops yield compared to untreated crops. [ABSTRACT FROM AUTHOR]
