Abstract
THE Imperial Bureau of Pastures and Forage Crops, Aberystwyth, has recently published three new bulletins. No. 27, “The Control of Weeds” (Is. 6d.), is a symposium dealing with the various aspects of the problem as it occurs in different parts of the world, particularly in the British Commonwealth and the United States. Increasing attention is being paid to this question; extensive research work on cultural, chemical and biological means of control is in progress, and important results are already available. The practices characteristic of each country make interesting comparison. The outlook regarding chemical measures of control, for example, is very different in the United States and Germany, stress being laid on the value of cultural methods in the latter case. In Australia and New Zealand biological means have been used, with spectacular success in the eradication of prickly pear in Australia. Poisonous weeds are the subject of an article from South Africa, while Canada's contribution is chiefly ecological.
