Winter wheat is ecologically different from other crops due to the overwintering dormancy stage that kills off many diseases and weeds, therefore, winter wheat isn’t prone to much disease or weed interference. But there are a few specific things to look out for to try and manage in the early stages.
Wheat is the only cereal that is seriously affected by Wheat Streak Mosaic Virus (WSMV). It causes stunted growth in wheat plants and lower seed production. WSMV is transmitted by the wheat curl mite and by leaf rubbing. Mites can be blown from field to field by the wind and can overwinter on winter wheat. Its development depends on the population of mites, virus-infected wheat plants, and sufficient moisture for good plant growth and rapid mite reproduction. A severe outbreak can occur when there is an abundance of mites in a spring wheat field and a field of winter wheat is planted early next to it.more about diseases
Weed control in winter wheat is aided by the crop’s fall-growth habit, vigorous spring growth, and early maturity. In many instances, wild oat control is not required and broadleaf weed control can be achieved with relatively inexpensive products. This benefit not only is of value in the year winter wheat is grown, but is also an important tool for maximizing the effectiveness of other crop protection products in other crop years. For example, avoiding a graminicide during the winter wheat year can help avoid or manage the development of herbicide resistance.more about weeds
