Practical Control of Wireworm with 'Gammexane'

Abstract

IF further work establishes the effectiveness of 'Gammexane', against wireworms¹, the problem in future will be to decide which fields are to be treated with this substance. Unless it is to be applied to every field containing wireworms (this would mean most of the cultivated land in Britain) it will be necessary to be able to predict in advance which fields are likely to be attacked. I am convinced, as a result of experiences as a member of the wireworm advisory team stationed at Cambridge during the War, that such predictions are more difficult to make than is commonly believed. The assumption that wireworm damage increases with rising population must be used with reservation in making such predictions.
