Evaluation Of Plant Extracts For The Control Of Seedling Bacterial Blight Of Cotton Induced By Xanthomonas Campestris Pv. Malvacearum (Smith) Dye

📄 Project Abstract

Aqueous extracts of six plants, namely Garlic {Allium sativum L), Custard apple Annona senegalensis L), Borreria verticillata L., Jatropha curcas L, the Sweet basil (Ocimum basilicum L), and Neem (Azadirachta indica (A.), Juss) were evaluated for the control of bacterial blight of cotton. Streptomycin and three preprietory chemicals; bronocot (12% broropol), Apron plus (10% metalaxyl, 6% carboxin, and 34% Furathiocarb) and Apron star (20% Thiamethoxam, 20% Metalyaxyl-M, and 2% Difenoconazole) served as checks alongside an untreated control. Assessments of the extracts was done in vitro, in the glasshouse, and in the field to determine the efficacy of the extracts against the disease. Two methods were used to evaluate the plant extracts in vitro, namely, dilution plate count and agar cup methods. Garlic (A. sativum) was found to be most effective, and significantly reduced bacterial population and growth over the untreated control. A. senegalensis, B. verticillata, and J. curcas were mo...
