Weeds, disease and insects in mustard

In the final part of a 4-part series on mustard agronomy, Ross McKenzie turns his attention to pests

Weed control is generally my greatest concern when growing mustard. Weed competition can greatly reduce mustard yields by competing for available light, nutrients and moisture. Although mustard seedlings are not very competitive with weeds, there are ways that growers can reduce the early effects of weeds: burndown of weeds in fall and/or early spring before […] Read more
