Abstract:

In this experiment, different districts of South Gujarat were closely examined for various diseases in different cultivars/ Bt hybirds. A roving survey was conducted on cultivars’ field during the crop season and a fix point survey on cotton crop was conducted periodically at Research farm, Surat. During the season, only Bacterial leaf blight disease was found on G. Cot. Hy. 12. The incidence of Bacterial leaf blight disease (BLB) was noticed from 33rd to 50th standard week with the maximum disease intensity in the third week of October (22.5 %) i.e. in 42nd Met. week. Results indicated that Bacterial leaf blight (BLB) disease has positive correlation with the maximum and minimum temperature and sunshine hour for the disease development. Survey was conducted on farmer’s field as well as on Research farm. Bacterial leaf blight incidence varied from 0.0 to 22.5 PDI and Alternaria leaf spot disease varied from 0.0 to 12.0 PDI in different cultivars/ hybrids on Research farm. Whereas, in case of farmer’s field, roving survey was mostly carried out on BG II hybrids, the BLB incidence was in the range of 0.0 to 4.5 %, 0.0 to 12.0 % and 2.0 to 4.5 PDI in Surat, Bharuch and Narmada districts, respectively. Moreover, Alternaria leaf spot disease was observed to the tune of 0.0 to 8.0 %, 0.0 to 10.0 % and 0.0 to 1.0 PDI in Surat, Bharuch and Narmada district, respectively.
