New herbicides for control of linuron resistant pigweed species in carrots

The inability of linuron to control annual pigweed species is a serious threat to successful carrot production. The objective of this study is to further the development of an integrated weed management strategy for carrots with a special focus on management and control.

Field trials were conducted at the Ontario Vegetable Crop Research Station located in Kettleby, Ontario. The identification and potential registration of new herbicides for the control of linuron-resistant pigweed species will provide new weed management options for growers in-regards to the best management practices for current and future herbicide-resistant populations.
