Antifungal Activities of Ageratum conyzoides L. Extract against Rice Pathogens Pyricularia oryzae Cavara and Rhizoctonia solani Kühn

Blast disease and sheath blight disease caused by infection with Pyricularia oryzae and Rhizoctonia solani, respectively, are serious fungal diseases in paddy fields. Although synthetic fungicides have been used to control these diseases, the development of ecol...
