“Spray-Seed”: The Western Australian direct sowing system

Abstract

“Spray Seed,” which involves direct combine-drilling of cereals after killing weeds and regenerating pasture grasses with a mixture of bipyridyl herbicides, has been developed in Western Australia as a means of minimizing the loss of grazing land during seedbed preparation at a time of the year when feed is critically short for sheep and other livestock. The results of several years’ field trials are summarized together with practical experience from a farm 120 miles north-east of Perth.
