Abstract

Chilli is a famous crop for its daily usage for its flavor and pungency. It is vastly affected by several diseases specially, Fruit rot disease cause huge loss both in quality and quantity. Resistance inducers such as Nicotinic Acid, Napthalene acetic acid, Salicyclic acid, Silicic acid and Sodium silicate were examined for control of Colletotrichum truncatum causing fruit rot in chilli at concentration viz., 50ppm,75ppm and 100ppm by using culture plate assay. Salicyclic acid with per cent inhibition of 96.65% found to be best in inhibiting mycelia growth of pathogen and found to be superior over other resistance chemicals both in culture plate assay and pot culture with less incidence of 21.6%. This study investigate management of Colletotrichum truncatum and further induce growth promotion in chilli plant when sprayed as foliar application. Therefore, the study provides dual promotion by managing pathogen as well as promote growth of plant and obtain better yield with quality pro
