Changes in chlorophyll, sugar and phenolic compounds in resistant and susceptible genotypes of greengram were studied. The chlorophyll and sugar content were found to decrease due to the infection of Colletotrichum truncatum and the rate of decrease was more in susceptible genotypes (Chinamung, Yellowmung and S-4) than resistant genotypes (TM-96-2 and TARM-18). However, phenol content was found increased due to infection and the rate of increase was higher in resistant genotypes. Comparatively lesser sugar and higher phenol content were observed in resistant and moderately resistant genotypes than in susceptible genotypes.Keywords

Sunflower is reported to suffer heavy losses because of fungal, viral and bacterial diseases and one of the prominent diseases among them is powdery mildew caused by E. cichoracearum. Recently Powdery mildew is most important limiting factors for production of sunflower in Karnataka. Management of powdery mildew in sunflower was studied in both in vitro and in vivo conditions. Azadirachtin, NSKE, Turmeric (leaf extract), Lantana camara (leaf extract) and Ipomoea carnea (leaf extract) were effective in inhibiting spore germination of pathogen both under in vitro condition at 5 per cent concentration. Similar trend was observed in field condition also with Azadirachtin and NSKE at 5 per cent concentration with least disease incidence of 25.78 and 27.56 per cent disease index, respectively in contrast to 83.33 per cent disease index in control.Keywords
