Effect of Agrochemical (2,4-D) on Morphological Aspects of Cassia tora Linn

Abstract

Present investigation carried out in the botanical garden and research laboratory of the college. The herbicidal activities of agrochemical (2,4-D) on Cassia tora Linn. have been studied. The morphological responses might produce some light on the manner by which this compound affected on plants. The plants were sprayed with aqueous solution of different concentrations of herbicide from 50 to 1000 ppm. 2,4-D at all concentrations showed the effect like epinasty, bending of stem and petiole, chlorosis and necrosis on leaves. The leaves burned, roots become swollen and finally decayed. Vegetative growth of plants was retarded and finally plants dried, the lethal dose of 2,4-D was 375 ppm.
