Plant Protection, Chemical Fungicides, Botanicals, Azadiracta sp., Parthenium sp., Fungal Pathogens, Poison Food Technique


Plant protection is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of plant protection chemicals. Botanicals possess a variety of promising properties which make it a better biocontrol agent. The objectives of the present study were to isolate Fusarium sp. from soil and to check the effect of botanicals against this fungal pathogen in-vitro. The antagonistic activity of botanicals was studied by co-inoculation with the Fusarium sp. isolated from rhizosphere soil. In poison food technique, the botanicals in different concentration, showed decrease in the growth of the fungal pathogen. Maximum inhibition was observed in 10% Azadiracta sp. with 64% inhibition followed by 5% Azadiracta sp. with 57.8%
