Preventative Control

The best way to fight weeds and pests is to prevent them from establishing in the first place.

Preventative control refers to methods that aim to prevent weeds or pests from becoming established. Examples of preventative control include improved sanitation, eliminating pest habitat, using certified weed free seed, only transporting hay that is weed free, not moving firewood across state lines, making sure equipment is cleaned before moving from one location to another. See a complete list at this link:  preventive or exclusion strategies.

Mechanical Control

Mechanical/Physical control is the management of weeds or pests by physical means. Examples of this control type are: trapping, tilling, mowing, vacuuming, hand-weeding, hoeing, burning, freezing, steaming, mulching, caulking, screening and building repair, including new door sweeps.

Cultural Control

Cultural controls are practices that reduce pest establishment, reproduction, dispersal, and survival. Some examples include using plants that are resistant to pests and more competitive with weeds, proper plant spacing, amount and frequency of irrigation, good soil fertility, raising the mowing height of turf to shade out weeds, aerating turf to reduce compaction and plant stress.

Chemical Control

Many factors determine when, where, and how a particular pesticide can be used most effectively. If pesticides are an option under consideration, what is the best way to choose them?  Pesticides selection should be based on the best active ingredient(s) and formulation for the situation considering the combination of availability, economics, effectiveness, resistance management, and most importantly safety.

Rotate the use of pesticides with different modes of action between treatments to help delay the development of pesticide resistance in weed, insect, and disease populations. The mode of action group code can be found on pesticide labels or at Pesticide Information Center Online.

The Restricted entry interval (REI) as specified by the label of the pesticide applied is the minimum period of time after an area is treated with a pesticide during which restrictions on entry are in effect to protect persons from potential exposure to hazardous levels of pesticide residues.

Biological Control

Biological control includes the use of organisms to control the germination of weed seeds or the spread of established weeds or pests. Examples of biological controls include pathogens, insects, goats, sheep and falcons.
