Biological control (biocontrol) tools for weeds include insects, mites, nematodes, pathogens, and grazing animals. Grazing animals and insects can directly impact weeds and reduce their growth and competitiveness. Other biocontrol organisms will feed on weed seeds and reduce seed return to the soil seed bank.

2018年9月5日 · This work therefore presents an overview of the biological approach to weed control with focus on the basic concepts, underlying principles, procedures and current practices, cases and causes of failure and successes.

2015年8月27日 · Biological weed control strategies can potentially address this need and provide novel modes of action that will inhibit the growth of weeds that are resistant to more commonly used herbicides.

Biological control agents are ideally employed for use against established weeds rather than new invaders. The effectiveness of biological control can range from highly effective, where people may use this approach and exclude other weed control measures, to failure.

Biological control of weeds is broadly defined as the use of an agent, a complex of agents, or biological processes to bring about weed suppression. All forms of macrobial and microbial organisms are considered as biological control agents.

Biological control of weeds includes insects and pathogens. Biological control agents of plant diseases are most often referred to as antagonists. Predators, such as lady beetles and lacewings, are mainly free-living species that consume …

2024年9月3日 · Biological control (biocontrol) involves the reduction of pest populations through the use of natural enemies such as parasitoids, predators, pathogens, antagonists, or competitors to suppress pest populations.

Biological control has most frequently been applied against these alien weeds and attempts are made to restore the natural control of these weed pests by introducing one or more host-specific, damaging natural enemies from the native region of the weed.

Biological weed control is not a widely used practice. It is utilized mainly in range and grasslands. This approach is using some sort of biological predator – perhaps an insect, plant pathogen or even an animal, such as goats to control weedy or invasive plants.

Chemical inputs to control weeds are often impractical or ineffective in organic agriculture, so being able to select crop varieties with the ability to suppress weed pests in the field is a valuable tool for organic farmers. ... Biological Control. 49: 11–16. Ozores-Hampton, M., R. McSorley and P. A. Stansly. 2012. Effects of long-term ...
