Phytochemical Screening, Proximate and Mineral Composition of Ipomea batatas (L.) and Zea mays (L.)

Abstract :

Anthracnose and powdery mildew are the two major foliar diseases of chilli crop and prevalent in Tamil Nadu. Field surveys were conducted in 12 districts of Tamil Nadu. They revealed that the Per cent Disease Index of chill anthracnose ranged from 8.80 – 78.89. Field surveys conducted in 7 districts of Tamil Nadu revealed that the disease incidence of chilli powdery mildew was ranged from 22.74 to 53.36 per cent. Seventeen isolates of Colletotrichum capsici were isolated from the samples and were named as Cc1 to Cc17 as continuous series. Three isolates were identified as C. gloeoesporioides and were named as Cg1, Cg2 and Cg3. This indicated that C. capsici is a major pathogen involved in the anthracnose disease of chilli in Tamil Nadu. The pathogenicity tests conducted for C. capsici and L. taurica resulted in the development of typical symptoms of the anthracnose and powdery mildew.
