Infestations and distribution of Rhopalosiphum padi (L.) on different varieties of barley and oats, effect of nitrogen fertilization and chemical control
Infestations of Rhopalosiphum padi were compared between common varieties grown at nitrogen levels of 50, 100 and 150 kg/ha in 1986 and 1988, and controlled with dimethoate in 1988.
