Jarošová, Jana ; Bartáková, Pavla ; Broženská, Michaela ; Kumar, Jiban
One of the most important viruses affecting cereals in the Czech Republic is Barley yellow dwarf virus (BYDV). BYDV is transmitted by cereal aphids and intensity of its occurrence varies strongly in individual years. Insecticide application protects the stands against virus transmission.

The methodology is meant to serve mainly to farmers, agronomists and agricultural advisors.
