Wheat diseases

From Wikipedia, the free encyclopedia

=In Europe=Cereals are at risk from numerous diseases due to the level of intensification necessary for profitable production since the 1970s. More recently varietal diversification, good plant breeding and the availability of effective fungicides have played a prominent part in cereal disease control. Use of break crops and good rotations are also good cultural control measures. The demise of UK straw burning in the 1980s also increased the importance of good disease control.Active control measures include use of chemical seed treatments for seed-borne diseases and chemical spray applications for leaf and ear diseases. Development of resistance by diseases to established chemicals has been a problem during the previous 30 years.

Fungicides

Some cereal fungicide groups and examples of active ingredients:
  • Benzimidazoles
  • carbendazim
  • Ergosterol biosynthesis inhibitors
  • prochloraz
  • flutriafol
  • tetrachonazole
  • Morpholines
  • fenpropimorph
  • Strobylurines
  • kresoxim-methyl
  • Phthalonitriles
  • chlorothalonil

    • Principal diseases

  • Barley yellow dwarf virus, BYDV
  • Brown rust Puccinia recondita
  • Bunt (see covered smut) Tilletia caries
  • Ergot Claviceps purpurea
  • Eyespot Pseudocercosporella herpitrichoides
  • Leaf spot, glume blotch, see wheat septoria, septoria nodorum, septoria tritici
  • Mildew (see cereal mildew) Erysiphe graminis
  • Seedling blight Fusarium spp., Septoria nodorum
  • Sharp eyespot Rhizoctonia cerealis
