Weed control volunteer plants

Due to its ability to outcompete weeds, Jerusalem artichoke was once advocated as a form of weed control in soils given no other form of cultivation. Two years of Jerusalem artichoke cultivation, for example, appeared to clear soil of quack grass (Shoemaker, 1927). However, Jerusalem artichoke is more commonly known as a weed itself, especially in cereals in the U.S. The tubers are difficult to harvest completely and volunteers result. If Jerusalem artichoke is cultivated on the same piece of ground for a number of years, volunteer plants developing among newly planted tubers pose little problem. If the following crop in a rotation is maize/com, Jerusalem artichoke can become a significant weed problem. Chemical, mechanical, and control approaches are used to control Jerusalem artichoke as a weed (see Section 12.3.2). 

It is important to control volunteer crop plants and those weeds that are alternative hosts to pests in other crops so that the pest life-cycle can be broken. 

Rotations. Growing leys and various arable crops that ate planted at different times of the year usually leads to a different weed flora. There is also an opportunity to use different types or groups of herbicides. This method is useful if there are difficult weeds such as barren brome, volunteer potatoes, herbicide resistant black-grass and weed beet to control.
