This study investigated treatment of mango (Mangifera indica L.) fruit with 2 host defence-promoting compounds for suppression of anthracnose disease (Colletotrichum gloeosporioides). Cultivar ‘Kensington Pride’ fruit were treated at concentrations of up to 1000 mg/L with either potassium phosphonate or salicylic acid. Applications were by various combinations of pre- and postharvest dips and vacuum infiltration. Postharvest treatments at up to 2000 mg/L salicylic acid were evaluated in a second fruiting season. Fruit were either uninoculated or inoculated with the fungal pathogen. Colour, firmness and disease-severity were assessed during shelf life at 23°C. There were no significant (P&gt;0.05) effects of potassium phosphonate or salicylic acid on anthracnose disease severity in the first season. Moreover, phosphonate or salicylic acid treatment did not significantly affect fruit colour or firmness changes. There were significant (P&lt;0.05) reductions in anthracnose severity in the second season, especially at the highest concentration of 2000 mg/L salicylic acid. Mango fruit skin colour and firmness changes were also slowed down significantly (P<0.05). These effects of salicylic acid were attributed to inhibition of mango fruit skin ripening (senescence).

Kurukshetra, a state of India is a historical place having global significance linked with its multifaceted aspects concerning education, science education, engineering colleges, museums and above all some sites and spots which are witnesses to the events of world famous war namely, “Mahabharata”. The studies reveal that urbanization processes have turned rural Kurukshetra into a modern semi-urban area with distinct urban features by creating “Urban Estates”. This is an activity which has two faces: Eco-friendly face and adverse ecological face.The generation of an attraction, ultra modern city equipped with vast green belts; impressive avenues having intense plantations of trees, bushes and profusely dotted with Civil Parks is a phenomenal change. One of the most impressive eco-friendly façade of the new environs is the ambience presence of orchards and plant nurseries and there is practice of “Kitchens-Waste” disposal which is disposed off at a safe place to convert it into organic manure. The best of sanitary conditions are in place which is one more environment friendly aspects. A very well laid out “Mini-Secretariat” encompassing virtually each and every office of the District Administration is intensely covered by very thick cover of trees and a new experiment, pioneered first by Haryana Govt.However, the negative features are many to negate the over all positive features. Foremost is related with discarding the traditional and endemic trees like Shisham Dalbergia sissoo, Neem Azadirachta indica, Beri Morus alba, Peepal Ficus religiosa, Banyan Ficus benghalensis and Mango Mangifera indica trees for tree plantations in favour exotic varieties.
