The Biology of reed (Phragmites communis) in relation to its control. 1968. Proceedings of the 9th British Weed Control Conference. 1968, 392—7.


Reedswamp and reedmarshes are common in many alluvial and coastal districts of Britain. Reeds (Phragmites communis Trin.) are a useful cash crop in themselves, and have considerable amenity value in land use, and scientific value as a refuge for wildlife and as part of a hydrosphere. Cutting, grazing and drainage are the best methods of control. Cutting in July, when the cut shoots are not replaced, is best, as half the growing season is then lost to the plant. Phragmites can be lowered from the dominant to a sparse member of a community fairly easily, but it will persist indefinitely except under very severe strain, such as cattle grazing throughout the summer for many years. Involuntary chemical control occurs with salt in sea water, and planned control, for different purposes, with Dalapon and KC103. Dredging, ploughing and shading are specialised in their application or effects.
