Allelopathic effects of Crotalaria juncea and dimethyl disulfide (DMDS) on tomato plants in the future development of a biocontrol method against root-knot nematodes

Abstract: Plants treated with Crotalaria juncea and dimethyl disulfide (DMDS) showed higher growth than control plants. Total soluble sugars were higher in the roots of DMDS treated plants as compared to the levels measured in the roots of plants treated with C. juncea or control plants. Plant defence gene expression – salicylic acid, jasmonic acid and ethylene pathways – was higher in plants treated with DMDS and C. juncea.
