Root growth Inhibition with compositions comprising diquat bromide, ammonium sulphate and other herbicidal agents

摘要

Disclosed is the use of diquat bromide as a root control agent. It is believed that by applying diquat bromide to produce a high local concentration on the target root, the inactivating effects of local organic substances are overcome, and the diquat bromide kills root tissue by its desiccating activity. The inactivation of diquat bromide by organic materials, under these circumstances, becomes an advantage, as it prevents toxic levels of diquat bromide from travelling downstream from the point of application.
