In vitro antagonism of native biocontrol agents on coconut pathogens revealed that all the three isolated native Trichoderma spp were found inhibitory to the mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora. Maximum percent inhibition of mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora was obtained by Trichoderma viride followed by Trichoderma hamatum and Trichoderma harzianum. | Studies on in vitro antagonism of native biocontrol agents on coconut stem bleeding and bud rot disease pathogens
