Control Methods

There’s no ‘silver bullet’ when it comes to controlling weeds. Thorough control is likely to involve a combination of the following methods described below.

Cut and Paint Method

Cut plant as close to ground as possible, apply undiluted Round Up or Vigilant Gel withinn 30 seconds.

Manual Control

Physical or mechanical removal of the plant without the use of herbicide or following the use of herbicide.

Chemical Control

Physical or mechanical application of herbicide absorbed by the plants foliage, roots or trunk (see cut and paint).

Biological Control

The use of one living species, the agent, to controll an unwanted plant, the target.  Weeds are commonly controlled by introducing plants, fungi and insects that inhibit their growth. Will not completely kill a weed but it will slow down the invasion process.

Soil Improvement

Healthy soils suppress weeds. Healthy soil requires; air and moisture, food (to feed soil life), shelter and energy (soil fertility, the correct ratios of trace elements).
