Abstract: Cotton (Gossypium spp.) is one of the most important fiber crops playing a key role in economic and social scenario of the globe. It provides employment and sustenance to a population of nearly 42 Million people, who are involved directly or indirectly in cotton production, processing, textiles and related activities. Looking to the experiment, different fungicides were evaluated in cotton crop under field conditionagainst the boll rot and different diseases. Total seven treatments including control were evaluated in this trial from which, treatment T4 (24.17 PDI) followed by T5 (25.67 PDI) recorded minimum Bacterial leaf blight infection in comparison to the treatment T7i.e. control (39.50 PDI) in RCH 2 BG II hybrid.For Alternaria leaf spot disease, treatment T4 (5.33 PDI) were recorded significantly minimum Alternaria leaf spot disease in RCH 2 BG II hybrid as compared to the T7i.e. control (17.67 PDI) followed by T5 (8.17 PDI) and T6 (9.00 PDI) treatment.The lowest boll rot incidence was observed in the treatment T4 (13.83 PDI) followed by the T5 (16.17 PDI) and T6 (17.33 PDI) treatment as compared to the control T7 (29.83 PDI).The highest seed cotton yield was recorded in the treatment T4 (2682.00 kg/ha) followed by treatment T5 (2427.00kg/ha) and treatment T6 (2308.67kg/ha), respectively.
