Impact of Dactyloctenium aegyptium Weed Extracts on Soil Borne Fungal Phytopathogens and Legume Crop-Vigna

Abstract

Background: As it is well known that intensive and indiscriminate use of chemicals in agriculture has caused very serious problems to the environment and as well as the human beings as it has poisoned our food also contaminated for soil and water. Aim to make light of the adverse effect of these chemical pesticides the extract of Dactyloctenium aegyptium was used against the soil borne plant pathogens i.e., Fusarium oxysporium, Rhizoctonia solani, Sclerotinia sclerotiorum and Sclerotium rolfsi. Methods: In this field-laboratory investigation during 2018-19, different part of Dactyloctenium aegyptium extracts show the antifungal activity against soil born fungal phyto-pathogen and also show the effect on vigna (Moong) at different parameters. The antifungal activity was resolute by well diffusion method. It is very effortless and usual method to resolve the inhibition zone. Result: Our investigation in which the heptane extract of the Dactyloctenium weed both part s was found to be most effective against the fungal plant pathogens i.e. 0.00 over the control which was 6.3 and 5.8 in Fusarium oxysporium and Rhizoctonia solani respectively and extract in ethyl acetate and butyl alcohol was show lowest effectiveness against Rhizoctonia solani, Sclerotium rolfsi i.e 5.3 and 6.4. In case of green gram germination, Dactyloctenium aegyptium in different solvent at 25% concentration, butylalcohol was the highest in increasing the germination percentage (100) show effectiveness. The leaves, root and stem length show highest effectiveness respectively methanol, heptane and water. The overall effectiveness of the different extract against the fungal plant pathogens were found significantly effective.
