- Title
ASSESSMENTS OF LOSSES IN SUGAR BEET DUE TO VIRUS YELLOWS IN GREAT BRITAIN, 1942-52.

- Abstract
This article focuses on the records of the incidence of Virus Yellows in sugar beet crops which have been made each year since 1942 as part of a survey of the incidence of sugar beet disease in Great Britain. The survey is made by the agricultural staff of the British Sugar Corporation. Instruction in disease recognition and methods of counting has been given to the sugar factory agriculturists and fieldmen by means of lectures, field courses and circulars. There was a gradual build-up of the disease over four years from a very low level of infection in 1942 and 1946 to the peak infections in 1945 and 1949. The lowest recorded level of infection was in 1951, but in 1952 very heavy infestations of both green and black aphids early in the summer resulted in a widespread, though rather late, development of the disease.
