- Title
THE RELATION OF ANNUAL INCIDENCE OF BEET YELLOWING VIRUSES IN SUGAR BEET TO VARIATIONS IN WEATHER.

- Abstract
The article discusses the relation of annual incidence of beet yellowing viruses in sugar beet to variations in weather in Great Britain. Most economically important viruses of agricultural and horticultural crops in Great Britain are aphid-transmitted and their prevalence in any year depends largely on the numbers and earliness of aphid migrants during spring and summer and the prevalence in sugar beet crops of beet yellowing viruses transmitted by Myzus persicae Sulz. Two viruses, beet yellows virus (BYV) and beet mild yellowing virus (BMYV), were considered together as causes of "beet yellows" because surveys had not discriminated between them. Hurst concluded that the mean daily air temperature in February was the main controlling weather factor, but that its effect could be modified by temperature in March and April.
