Investigation on the efficacy of bio-product - a biocontrol agent on Patchouli (Pogostemon cablin Benth.).

摘要

Fusarium sp. was found to be the most prominent among the fungi causing root rot diseases in Patchouli (Pogostemon cablin Benth.). Protection of the Patchouli from the diseases using chemical fungicides has been regular practice. However, constant uses will lead development of resistant to fungicides in the pathogens and also may harm to the beneficial rhizosphere microbes. The present work was undertaken to evaluate the efficacy of commercially available bio-control agent such as Bio-product (Trichoderma viride, Trichoderma harzianum and Pseudomonas fluorescence) on the control of Fusarium sp. root rot disease in Patchouli and accelerate growth. In-vitro experiment (dual culture technique) also exhibit significant inhibition of growth of Fusarium sp. by the above mentioned microbes. It was found to be very efficient in controlling the disease.
