Persistent perennial weeds


, : Persistent perennial weeds. Agric. Inst. Rev, 4: 99-101

Weeds in eastern Canada are not such a great problem as they are in the western provinces where a more extensive type of agriculture is established. Over 2000 farms in Manitoba are infested with leafy spurge; hoary cress is a serious problem in Alberta and Russian knap-weed in the southern irrigated areas of Alberta. Field bindweed has long been a problem in Quebec, Ontario and New Brunswick. Control of weeds is discussed with reference to the use of 2, 4-D on field bindweed and leafy spurge.
