Drivers of entomopathogenic fungi presence in organic and conventional vineyard soils

Entomopathogenic fungi (EPF) are important antagonists of soil-dwelling insect pests adapted to living in agricultural soils. Little is known about EPF in vineyards, where they could be effective against soil-borne pests such as grapevine phylloxera or larvae of the June beetle. However, the high frequency of fungicide applications might reduce the effectiveness of EPF in vineyard soils. We compared effects of organic and conventional...
