Production constraints due to Bipolaris sorokiniana in wheat: current situation and future prospects.
1994
Duveiller E. | Gilchrist L.
Spot blotch caused by Bipolaris sorokiniana is the major disease constraint limiting wheat production in the warmer areas. Controlling the disease requires an integrated approach to reduce the fungal inoculum. This can be achieved by using seeds with a low level of infection, spraying appropriate fungicides, eliminating secondary hosts and crop residues, and improving agronomical practices and genetic host resistance. However, breeding progress towards the selection of resistant genotypes, the key factor to increase yields or make wheat a commercial crop in several areas, has been slow due principally to the high variability of the pathogen and insufficient knowledge on environmental factors modulating disease expression and host response. Research needs to improve disease control are reviewed.
