Demonstrates the growth inhibition of Verticillium dahliae by root exudates from potato onion, indicating its potential as a biocontrol agent.
Potato onion (Allium cepa L. var. agrogatum Don.) when intercropped with tomato (Solanum lycopersicum L.) reduces the verticillum wilt of tomato significantly. Hence the root exudates from Potato onion was used to examine its effect on the growth and enzyme activities of V. dahliae, a soil-borne pathogen of tomato. Results showed that the root exudate inhibited the growth of V. dahliae and also inhibited its amylase, pectinase and cellulase activities.
