This article focuses on a new study which found that Italian ryegrass appears to mostly emerge in the autumn. The results cast doubt about leaving its control until spring and provide evidence to support the use of pre-emergence herbicides, especially where resistance is present. As a result, growers should aim to achieve effective chemical control in the autumn, Stephen Moss of Rothamsted Research says. Results from five sites show that 81% of total emergence took place in October, 13% in November and December and only 6% between January and April.
