Pre and Post Emergencies Damping off in Cotton

F. Azad Disfani and M. R. Zangi

Survey was conducted to provide objective of study damping off susceptibility in cotton genotypes. Experimental design was 9 x 2 factorial arranged in a Randomized Complete Block. The factor A was cotton genotypes and the factor B was fungicide (with carboxin Thiram and without it). Seedling damping off was recorded 10, 20 and 30 days after planting. Post emergencies damping off disease was ranked 0 to 3 degrees 20 days after planting. Data were analyses with MSTATC computer program. Results were showed Crema treatment with Carboxin Thiram was the least damping off 10 days after planting. Also, Carboxin Thiram treatment had the most damping off 20 days after planting in oultan genotype. Oultan genotypes x control interaction was the most post emergencies damping off (53%).
