There is some fear that such resistance might pass into weed populations so making both them and "volunteer" crop plants more difficult to eradicate.

It may take several years of pulling up the plant before it flowers, before the weed's takeover tendencies are blunted, but the weed population can be greatly reduced.

Resistance evolves after a weed population has been subjected to intense selection pressure in the form of repeated use of a single herbicide.

Mulches do help to keep any weed population down because the organic covering seals in the much desired soil moisture.

Once the undesired species in a pasture system are identified an integrated approach of management can be implemented to control weed populations.

One method to reduce weed populations is mechanical control, which uses tillage equipment to move soil and disturb weeds.

Mechanical, or manual, weed control techniques manage weed populations through physical methods that remove, injure, kill, or make the growing conditions unfavorable.

In Australia the moth, Samea multiplicalis was also released in the hopes that it would reduce the size of the weed population.

Due to the lack of a cool-off pond, the water used to cool the internal systems is deposited back into the lake, which enhances the weed population dramatically.

It controls the weed population and prevents weeds from emerging, particularly during the crucial development phase of the crop.
