The two mechanical control techniques most often used are tillage and mowing. Biological weed control refers to any technique that involves the use of natural enemies of weed plants to control the germination of weed seeds or the spread of established plants.
Herbicide application can provide the most effective and time-efficient method of managing weeds. Numerous herbicides are available that provide effective weed control and are selective so that grasses are not injured.
Physical weeding: It can be done manually, using tools like khurpi, or can be done using seed drills. Physical weeding is the most commonly used process of weeding. Chemical weeding: Weedicides like 2,4-D can also be used, but their use should be restricted as they are synthetic and are poisonous.
Water management: Water is the best control for weeds. Many weeds cannot germinate or grow under flooded conditions (e.g. most grasses and some sedges). Maintain a 2-5 cm water level in the field to minimize weed emergence and lower weed pressure.
Weed control can be achieved through killing weeds (particularly seedlings) with cultivation, herbicides, targeted weed control in wide-row cropping, targeted control of small patches of weeds and biological control tactics.
Slashing, mowing, dozing, pushing and felling
At times, controlling weeds using mechanical methods is preferred. However, care should be taken when machinery is used in the process. Disturbing the soil with mechanical control can: increase the likelihood of seed germination.
Remove weeds by hand as they appear. This will prevent them from producing seed and extending the invasion. Properly timed irrigation, mowing, and fertilization can keep weeds under control. In the first few weeks after planting turfgrass roots are fairly short, extending only into the top few inches of soil.
A sprinkle of natural wood chips, pine straw, compost, or grass clippings will block sunlight and stop new weed seeds from sprouting through the soil. A mulch layer of 3 to 4 inches thick will ensure that any breakthrough weeds are easier to remove since their roots won't be as deep.
Hand weeding
It is probably the oldest method of controlling weeds and it is still a practical and efficient method of eliminating weeds in cropped and non-cropped lands. It is very effective against annuals, biennials and controls only upper portions of perennials.

Weedicides, which are sprayed in fields to kill all weeds, can be used to control them. Tilling before planting crops also aids in the removal of weeds. Weeds are removed manually with a kauri, which entails regular uprooting or cutting of weeds close to the ground.
These undesirable plants are called weeds. Weeds can be controlled by methods called weeding. Tilling before sowing of crops helps in uprooting and killing of weeds, which may then dry up and get mixed with the soil. Weeds are also controlled by using certain chemicals, called weedicides.
Mulching. Mulching is an excellent strategy to keep weeds at bay around the plants. Spread the straw or pine shavings, feathers, and chicken dung over your garden when you clean out your coop in the fall. It will have decomposed sufficiently by spring for you to incorporate it into the soil.
Chemicals that are used to kill plants or weeds are called herbicides. Soil surface application: Herbicides are usually applied to soil surface to form a uniform herbicide layer.

Removing weeds throughout the gardening season means fewer to manage next year. These unwanted plants also serve as host for a variety of insects and diseases. Keeping them out of the garden can help reduce the risk of these pests infecting our desirable plants.
