The barley yellow dwarf virus situation in Western Europe - 1990 - Printed

15 ref.; Summary (En)

Barley yellow dwarf (BYD) is omnipresent in western Europe, being more or less important depending on weather conditions, latitude, and crop cultivated. Its importance increases north to south. Rhopalosiphum padi (L.) is the most widespread and important aphid vector. Three isolates-PAV-, RPV-, and MAV-like-can be found; PAV-like is the most severe, being ubiquitous. Depending on latitude, sowing date, and weather conditions, aphicide treatments are very often necessary to avoid yield reduction. For this purpose a forecasting system was developed in central France. Rice (Oryza sativa L.) cultivars resistant to BYD have been released in Italy
