We studied the allelochemicals stress induced by aqueous extract of Parthenium hysterophorus L. and synthetic phenolic compounds on the physiological responses of selected varieties of Kenyan Zea mays L. (H625, H614D, DH02, H513, H6213), Phaseolus vulgaris L. (GLP2, GLP92) and Vigna radiata (L.) R. Wilczek (KS20). The aqueous extracts significantly inhibited the growth of test crop varieties than control. However, the effects were variable depending on whether the phenolic compounds had hydroxy (-OH) or methoxy (-OCH3) ring substituents. Aqueous extracts of P. hysterophorus and phenolic compounds with -OCH3 groups (M-Anisic and P-Anisic acid) decreased the physiological responses of test plant, while, phenolic compound with -OH groups (Coumaric acid and Hydroxybenzoic acid) were stimulatory.
