White Sweet clover is a very difficult plant to control however as it does not spread<br />
vegetatively, restricting seed formation can allow for successful management (Cole, 1991).<br />
This can be accomplished through cutting of flowering plants and hand removal techniques<br />
performed for several consecutive years. Prescribed burning may also be used.<br />
• If a prescribed burn is to be used, managers need to consider the likelihood of<br />
cancellation of later burns as burns that are only performed periodically can actually<br />
cause the population to grow in size. In order for this technique to be successful<br />
managers need to burn early in spring followed by herbicide applications or physical<br />
removal techniques later in the fall. Do not use prescribed burns late in the fall as<br />
this has been shown to stimulate the growth of dormant seeds (Environment<br />
Canada, 2003).<br />
• Cutting of flowering plants and hand pulling should focus on first-year plants. The<br />
physical removal of plants should be performed in late fall or early spring and cutting<br />
should be performed before flowers develop.<br />
• If herbicides are used the effects to native species needs to be considered.<br />
• Biological control methods such as the use of Sweet Clover Weevil have so far<br />
proven to be ineffective.<br />
