Cotton (Gossypium hirsutum L.) is the world's leading food and fibre crop. Cotton recognized as "white gold" plays a pivotal role in the economy. In this experiment, different districts of South Gujarat were closely examined for various diseases in different cultivars. The cultivars susceptible to bacterial blight viz., Surat dwarf, LRA 5166 showed bacterial blight intensity to the tune of 15 and 30 per cent, respectively. Whereas, on other cultivars like G. Cot. Hy. 6 BG II and G. Cot. Hy. 8 BG II intensity was 0.2 per cent only. Alternaria incidence was also noticed in G. Cot. 100 in good proportion (10 to 12 %) while on other cultivars, it was negligible. Roving survey was conducted at Olpad, Bhadol, Takarma and Hansot, the bacterial leaf blight (BLB) was in the range 1 to 5 per cent whereas, Alternaria leaf blight (ALB) was in the range of 3 to 10 per cent.Keywords

Studies on bio-efficacy of insecticides against castor capsule borer, Conogethes (=Dichocrocis) punctiferalis Guenee on castor were carried out during Kharif, 2011-12. The results on efficacy of insecticides showed that chlorantraniliprole 20 SC @ 0.006 per cent and indoxacarb 14.5 SC @ 0.015 per cent were found superior and recorded 7.92 and 8.12 per cent capsule damage, respectively during spray schedule. At harvest, plots treated with chlorantraniliprole 20 SC (0.006%), indoxacarb 14.5 SC (0.015%) and emamectin benzoate 5 WG (0.002%) had found lower per cent capsules damage. Statistically higher castor seed yield was recorded in chlorantraniliprole @ 0.006% (3185 kg/ha), indoxacarb @ 0.015% (3110 kg/ha) and emamectin benzoate @ 0.002% (2760 kg/ha). However, cost benefit ratio was highest in indoxacarb 14.5 SC (1:16.62) followed by alphamethrin 10 EC (1:15.73) and chlorantraniliprole 20 SC (1:12.02).Keywords

Main objective of present study is to study the progress of the bacterial blight disease of cotton (BLB), caused by Xanthomonas campestris pv. malvacearum (Smith) dye, with relation to the environmental parameters. This is a common disease affecting the growth, development and yield of cotton. A field trial was conducted to determine the influence of environmental factors viz., rainfall periods, temperature and humidity on development of disease. Bacterial blight disease was recorded with its appearance and subsequently at weekly interval till it prevailed on G. Cot. Hy. 12. The result presented and indicates that the disease was first appeared in 36th Met. week (First week of September) with 1.37 per cent intensity and prevailed upto 48th Met. week i.e. last week of November (1.75 %) with its peak during 42nd week i.e. 2nd week of October (24.50 %).Keywords
