Direct Systems Management

Title: Direct Systems Management

Direct weed management can be broadly divided into two categories; weed management prior to crop planting and weed management during crop growth. During crop growth, an important goal is; how to remove weeds selectively without injuring the crop. The choice of weeding method and of implement depends in part on practical aspects such as the type of crop and soil. Contributing influences in selecting which direct method to use will also be dependent on economic factors such as purchase price, operating costs and labour requirements. Choice


	FLAMING WEEDS: Propane flame systems are an effective weed control alternative. New, more efficient hooded systems can meet the needs of growers seeking more sustainable weed control methods. Weeds can't become resistant to this method of control like they can with chemicals. New hooded systems are more effective than direct flame method.

of method will also depend on the size of the crop area to be weeded. On small areas or where high value crops are involved hand-weeding remains an option. However crops grown on a large scale often require less labour intensive methods. The following sections in direct weed management range from hand weeding to large mechanically operated options, as well thermal and other innovative methods.

Which Tool?

The most effective tool for the job will depend on when and how often the area is to be weeded and the nature of the crop and weed infestation. For instance, fixed harrows are thought more suitable for arable crops, while others like inter-row brush weeders may be considered to be more effective for horticultural use.
