Yield losses in potatoes, onions and rutabagas in Southwestern Ontario, Canada. The case for pest control
Yield losses in potatoes, onions and rutabagas due to insects, weeds and diseases were measured. In the absence of any pest control, average losses of 64 percent for potatoes on mineral soil, 85 percent for potatoes on organic soil, 100 percent for onions and 88 percent for rutabagas were recorded. Major single causes of loss were: potato leafhopper, Empoasca fabae (Harris) for potatoes on mineral and organic soil; weeds and early blight, Alternaria solani (Ell. & Mart.) for potatoes on organic soil; weeds, onion maggot, Delia antiqua (Meigen) and leaf blight, Botrytis squamosa (J.C. Walker) for onions; cabbage maggot, Delia radicum (Linnaecus) and weeds for rutabagas. The monetary losses experience and the cost of each pesticide programme were calculated
