Abstract
About this talk
The leaf extracts of different weed plants such as (Cannabis sativa, Lantana camara, Ageratum conzoides, Parthenium hysterophorus) in different organic solvents (methanol, acetone, ethanol and aqueous) were assessed in-vitro for fungitoxic activity against phyto-pathogenic, Phytopthora, Fusarium isolated from different soil samples where the Potato, Tomato, Capsicum grown in field. The assessment of fungitoxicity was carried out by food poison technique using four different extracts at 200 mg/ml and their activity was recorded as radial growth and percentage inhibition. Among the four extracts, ethanol and acetone extracts showed complete inhibition of growth of fungus; while methanol extract showed 50% inhibition and aqueous extract did not produce any inhibition of fungus. Findings from present study confirmed that ethanol and acetone extract of Ageratum conzoides, Cannabis sativa, Parthenium hysterophorus, can be used as biofungicide to control this phytopathogenic fungus.
