Knock-down resistance changes detected in grain aphid populations

Genetic changes have been detected by Teagasc in specific grain aphid populations that deliver what is called “super knock-down resistance” (kdr) to aphicide chemistries. This may have implications for the level of Barley Yellow Dwarf Virus (BYDV) found in Irish cereal crops in the future. However, more generally, Teagasc research scientists have found that the […] The post Knock-down resistance changes detected in grain aphid populations appeared first on Agriland.ie.
