The annual ryegrasses are valuable pasture plants in Western Australia, yet have become one of the major weed problems in cereal crops.
The key to cultural control of annual ryegrasses in cereal crops is an understanding of the factors which govern germination of the seed.
Covering the seed with soil keeps out light and provides a more stable moisture supply, bringing about a faster rate of germination. This is the basis of control programmes recommended in this article.
Recommendations for chemical control are also included.
