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

Mango fruit suffers from many post harvest diseases among them anthracnose [Colletotrichum gloeosporioides (Penz) Penz and Sacc.] In stem end rot [Botryodiplodia theobromae (Pat.) Griffon and Maubl.], Alternaria rot (Alternaria alternata Keissal) and black mould (Aspergillus niger V. Tieghem) are the important diseases which contribute to the post harvest losses of mango. The market survey conducted during 2015 in Dharwad, Gadag and Uttara Kannada districts revealed that, among the post harvest diseases of mango anthracnose showed maximum PDI (14.25) followed by stem end rot (8.85) and Alternaria rot showed least PDI (5.10). Among the districts surveyed maximum PDI (10.98) was recorded in Dharwad followed by Hubballi (9.01) and least PDI (6.53) was recorded in Ankola. Among varieties, Alphanso showed maximum PDI (10.66) followed by Pairi (7.83) and least PDI was observed in Ishadi (6.40) and Neelam (6.22). The PDI ranged from 6.22 to 10.66.Keywords
