ABSTRACT
Herbicide resistance continues to escalate worldwide, causing significant yield losses and increasing the cost of food production. This chapter outlines the major wheat-growing areas of the world, the factors implicated with the development of herbicide resistance, and the management factors commonly used in different regions to combat resistance once it has developed. Wheat is grown worldwide; it is the most widely adapted of all the cereals. The pattern of herbicide usage is closely related to the farming systems in different regions, levels of agronomic input, and socioeconomic factors and can directly influence the development of resistance. Successful management of resistance relies on reducing the seedbank and limiting the dispersal of resistant weed seed. Short-term economic gains have dictated the responses of both farmers and the agrochemical industry to the development of herbicide resistance in weeds.
