RESEARCH ON PRODUCTION OF BIOLOGICAL PRODUCTS OF CHAETOMIUM FOR CONTROLLING FUNGAL DISEASES ON TEA, COFFEE AND RUBBER

Abstract

Two strains of Chaetomium which were popular and with high antagonistic activity from tea, coffee and rubber soil in Northern Vietnam were identified, including Chaetomium bostrychoides and Chaetomium globosum. These strains had strongly antagonistic activity to Fusarium sp. causing root rot on tea, coffee and rubber and Colletotrichum sp. causing tea anthracnose. New identified Chaetomium strains were successfully used to produce biological products for controlling disease called CP2-VMNPB. The product composition was capable to exclude fungal diseases well such as Fusarium sp. (85.62%); Colletotrichum sp. (81.80%) after one month in laboratory conditions; in greenhouse conditions, the effect on root rot tea and coffee reached 83.30%, with powdery mildew disease on rubber Oidium Hevea, the effect reached 81.17% after 3 months.
