Early and late leaf spot disease

The tomato crop attacked by early blight, late blight, leaf spots, anthracnose, Dampimg off, buckeye rot, wilts and root rots. Among these Damping off diseases in tomato caused by Rhizoctonia solani is very common to see in nurseries, an increased incidence of blight caused by Rhizoctonia solani was noticed in recent past in major tomato growing areas of Ranga Reddy district of Andhra Pradesh.

Leaf spots are the most serious foliar fungal diseases of groundnut (Arachis hypogaea L.) World wide. Early leaf spot and late leaf spots, singly or together can cause losses in pod yield of over 50% and reduce the quality of the pod and fodder. Screening of genotypes and advance breeding lines is one of the primary objective for resistance breeding in groundnut. Present investigation was carried out to screen 33 advance breeding lines and 7 released varieties of groundnut against early and late leaf spot diseases.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

An experiment was conducted at College of Agriculture, Nagpur to screen forty different groundnut genotypes against tikka disease of groundnut during kharif, 2016-17 in randomized block design with three replications. Biochemical constituents of phenol, total sugar and chlorophyll at 45-50DAS (flowering stage) and 90DAS (pod development stage) were estimated from leaves of healthy and diseased samples. Forty genotypes of groundnut were screened for tikka disease under field condition.

A mutant population comprising of 42 primary mutants, 7 secondary mutants and 4 tertiary mutants along with the parent Dharwad Early Runner (DER) and eight most popular groundnut varieties were evaluated during kharif 2012 for various agronomic, traits and for resistance to rust and late leaf spot. The genotypes showed significant genotypic differences for all the quantitative and nutritional traits studied. They also differed significantly for rust and LLS resistance except for LLS at 70 DAS.
