What are the methods of weed control?

Answer 1

Two types of methods are used to control pests. Natural pest control methods are employed to reduce or eliminate infestations through companion planting, crop rotation, predatory animals or repellent plants, but without harming humans, crops and other organisms. In contrast, chemical pest control methods often employ harsh pesticides that may be applied systemically (targeting where plants are commonly ingested by pests) or sprayed aerially, but with harmful and residual effects on both human and animals living within the area.

Answer 2

The use of natural enemies is the predominant form of biological method used to control pests and weeds.

Specifically, nuisance animals and plants can be controlled by in ways similar to those of Mother Nature. The approach involves recognizing the objectionable animal's or plant's parasites, pathogens, and predators. A beloved, frequent means of biological control revolves around encouraging or introducing ladybug beetles (Coccinellidae family) to control aphids and psyllid insects (Apalara itadori) to contain Japanese knotweed (Fallopia japonica).

Answer 3

Biological, botanical, chemical, cultural, mechanical and physical describe the methods that are used for pest control. Biological and botanical methods respectively refer to maintenance of beneficial predators -- such as lacewings and ladybugs -- in feeding chains and food webs as well as respect for horticultural oil, insecticidal soap and plant-based pesticide treatment schedules whereas chemical methods reference non-organic, synthetic plant-killing products. Cultural, mechanical and physical methods respectively require attention to light, moisture and temperature needs of soil and soil food web members, employment of fences, row covers and sticky traps and reliance upon manual means such as gloved hand removal of leaf-swarming insect pests.

Answer 4

Biological, botanical, chemical, cultural and mechanical describe the methods of weed control. Biological and botanical methods call for natural enemies and organic treatments, such as host-specific insects and plant growth regulators and pre-emergents such as gibberellic acid and corn gluten, while chemical methods conjure up glyphosate. Cultural and mechanical methods involve controlled burns, extreme pruning and solarization by weighting down black plastic sheets.

Answer 5

This will depend on the type of pest you wish to control.
