Effect of Seed Quality and Combination Fungicide-Trichoderma spp. Seed Treatments on Pre- and Postemergence Damping-Off in Cotton.
ABSTRACT Good quality seeds of cotton cultivars often escaped pre-emergence damping-off incited by Pythium spp. and Rhizopus oryzae, and they were resistant to postemergence damping-off incited by Rhizoctonia solani. Poor quality seeds, however, were highly susceptible to both phases of seedling disease and required seed treatment in order to survive. Pre-emergence damping-off incited by Pythiu...
متن کاملA comparison between acid seed delinting and fungicide seed treatment in controlling cotton seedling damping-off disease*
Seed decay (rot) and seedling damping-off caused by Rhizoctonia solani are among the most important diseases of cotton which result in the significant yield reduction, application of expensive and harmful chemical fungicides and most importantly contamination of soil and agricultural environment. This study was conducted to investigate the possible efficacy of cotton seed delinting in the reduc...

متن کاملSeed borne fungi of rice from South Tamil Nadu
Fungi associated with seeds of five cultivars of rice were isolated by agar and blotter paper methods. The fungus was isolated from the contaminated surface of unmilled rice grain and identified based on their typical structure and basic characters as suggested by Barnett and Hunter (1972). Five pathogenic fungi, namely Aspergillus flavus, A. niger, Penicillium citrinum, Alternaria padwickii an...
متن کاملeffects of two systemic insecticides on damping-off pathogens of cotton
in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...
