Aphids can transmit barley/cereal yellow dwarf viruses (BYDV). Initially, aphids colonise relatively few crop plants. However, the second-generation tends to move away from the plant originally colonised. Controlling this generation is a key part of a BYDV management strategy. This DSS indicates the best time to monitor crops for aphids. If infestations are high, and non-chemical control options are unlikely to prevent second generation emergence, treatment should be considered.
