Determination of the infection pressure of potato virus YN (original) (raw)
Abstract
In 1976 consecutive series of plants of_Nicotiana tabacum_ ‘White Burley’ replaced weekly, were used as bait plants to determine the infection pressure of potato virus YN (PVYN) in a crop of ware potatoes in the centre of the Netherlands. The first PVYN-infected tobacco plants were found mid May. The course of infection of the tobacco plants was not correlated with the flight of_Myzus persicae_, which started towards the end of June. Aphid species other than_Myzus persicae_ presumably are responsible for the infection observed early.Rhopalosiphum padi and_Acyrthosiphon pisum_ flew much earlier than_Myzus persicae_ and are vectors of PVYN.
