Abstract
Treatments made at 2-week intervals on guava (Psidium guajava L.) with a 11 ratio of butoxyethanol esters of 2,4-dichlorophenoxyacetic acid:2,4,5-trichloro-phenoxyacetic acid (2,4-D:2,4,5-T) have shown it to be more susceptible when treatments are made during the wet season than during the dry season. Greater susceptibility is related to a plant condition characterized by many new leaves but little or no terminal twig elongation. A similar pattern of defoliation response is caused by 2-methoxy-3,6-dichlorobenzoic acid (dicamba) and 2,3,6-trichloro-picolinic acid (picloram) as by 2,4-D:2,4,5-T, but the period of maximum susceptibility based on defoliation percentages 1 year after treatment occurred later in the season.This publication has 0 references indexed in Scilit:
