| Abstract | ||
| This study was conducted at field of Plant Protection Dept., College of Agriculture, University of Baghdad during the summer season 2012-2013. The study included evaluation of Trichoderma harzianam and Psuedomonas fluorescens and beltanol against Rhizoctonia solani causal of seed decay and damping off seedling of cotton pre and post emergence. Field results indicated that treatment of cotton seed with T.h. and P.f. significantly achieved highest seed germination (86.0%) and disease severity 0.4 compared to other treatment. Also, all treatments indicated superiority on control treatment (Pathogenic fungus) which showed 16% seed germination and disease severity 3.8. Activity of different treatments increased plant length, dry matter for root and vegetative part of cotton plant. Treatments of integration between bioagents and beltanol at half rate achieved good activity in controlling R. solani which help in reducing environmental pollution. | ||
