Weed control Weeding: this is done in seed beds in which the hoe can not be used. Larger plants are best pulled out. Hoeing and shoveling: this cuts the weeds off just below the soil surface. A shovel scrapes the soil surface, one makes a pushing movement with it as you move back. A hoe is always pulled towards oneself while one moves forward. The best moment is with dry sunny weather after a period of rain, when the soil has dried up sufficiently. The hoeing and shoveling is done when the weeds are as small as possible. The larger the weed, the harder. In dry and sunny weather the weeds can be left to decompose on the soil. In wet weather, the weeds need to be removed from the soil so they can not grow back.

What is weed in gardening?

Weeds are the plants, which grow where they are not wanted (Jethro Tull, 1731) Weeds can be referred to as plants out of place. Weeds compete with crops for water, soil nutrients, light, and space & thus reduce crop yields. Weeds typically generate large numbers of seeds, assisting their spread.

What is the role of light intensity in weeds?

Light intensity, quality, and duration are important in influencing the germination, growth, reproduction & distribution of weeds. Photoperiod governs the seed setting and maturation and on the evolution of different ecotypes within a weed species.

Classification according to an origin of weeds: Several weeds in India originated in some other part of the world. For e.g. Convolvulus sp –Eurasia, cyperus –Euphorbia,-Europe, Lantana –Africa. Classification according to soil: Of the several variables of soil, soil pH is implicated frequently with the distribution of weed species.

Why are weeds dangerous?

The many reasons for controlling weeds become more complex with the increasing development of technology. Plants become weeds as a function of time and place. Tall weeds on roadsides presumably were not problematic prior to the invention of the automobile. However, with cars and increasing numbers of drivers on roads, tall weeds became dangerous, potentially obscuring drivers’ visibility, particularly at intersections. Sharp-edged grasses are nominal nuisances in a cow pasture; when the area is converted to a golf course or a public park, they become an actual nuisance. Poison oak ( Toxicodendron diversilobum) is rather a pleasant shrub on a sunny hillside in the open country; in a camp ground it is a definite health hazard. Such examples could be given ad infinitum to cover every aspect of agriculture, forestry, highway, waterway and public land management, arboretum, park and golf-course care, and home landscape maintenance.

What is a farm tractor tilling row crops?

What are the virtues of row crops?

The principal virtue of cultivation of row crops is the control of weeds. Any method of weed control that minimizes tillagetends to conserve soilstructure and maintain fertility. In addition to tillage, other mechanical methods of weed control involve burning, grazing, and the use of ducks or geese in certain crops (in cottonand mintespecially).

How did mechanical weed control begin?

Mechanical weed control began when humans first pulled weeds from their cereal cropsand attempted to grow single plant species, free from all plant competition. That was the start of monoculture, a method that since has come to dominate agriculture.

What are the mechanical methods of weed control?

In addition to tillage, other mechanical methods of weed control involve burning, grazing, and the use of ducks or geese in certain crops (in cotton and mint especially). All of those methods have drawbacks: there is the arduous, painful nature of hand weeding; the repetitious and often harmful nature of clean tillage with machinery; the slow, fuel-consuming nature of burning; and the costly requirement of livestock or fowl for the biological grazing methods. Tillage, still the most widely used method of row-crop weed control, has been greatly improved by development of precision seeding and close preadjustment of tiller tools, allowing the passage of weed knives within an inch or less of the young crop plants. Despite these improvements it is known that weed knives injure crop roots, especially late in the tillage season. Additionally, tillage tools can spread perennial weeds rapidly, bringing about rapid infestation of whole fields.

Is the category of weeds ever changing?

The category of weeds thus is ever changing, and the term is a relative one. Weeds interfere with a variety of human activities, and many methods have been developed to suppress or eliminate them. These methods vary with the nature of the weed itself, the means at hand for disposal, and the relation of the method to the environment.

What are weeds competing for?

Need for control. Weeds compete with productive crops or pasture, they can be poisonous, distasteful, produce burrs, thorns or otherwise interfere with the use and management of desirable plants by contaminating harvests or interfering with livestock. Weeds compete with crops for space, nutrients, water and light.

How do weeds propagate?

Annual and biennial weeds such as chickweed, annual meadow grass, shepherd’s purse, groundsel, fat hen, cleaver, speedwell and hairy bittercress propagate themselves by seeding. Many produce huge numbers of seed several times a season, some all year round. Groundsel can produce 1000 seed, and can continue right through a mild winter, whilst Scentless Mayweed produces over 30,000 seeds per plant. Not all of these will germinate at once, but over several seasons, lying dormant in the soil sometimes for years until exposed to light. Poppy seed can survive 80–100 years, dock 50 or more. There can be many thousands of seeds in a square foot or square metre of ground, thus any soil disturbance will produce a flush of fresh weed seedlings.

What was the name of the tractor that farmers hitched behind their combines to catch ryegrass seeds?

In the mid-1980s, a few farmers hitched covered trailers, called “chaff carts”, behind their combines to catch the chaff and weed seeds.

What causes a plant to die from a hot foam burner?

Hot foam (foamstream) causes the cell walls to rupture, killing the plant. Weed burners heat up soil quickly and destroy superficial parts of the plants. Weed seeds are often heat resistant and even react with an increase of growth on dry heat.

How do flame weeders work?

Flame weeders use a flame several centimetres away from the weeds to give them a sudden and severe heating. The goal of flame weeding is not necessarily burning the plant, but rather causing a lethal wilting by denaturing proteins in the weed. Similarly, hot air weeders can heat up the seeds to the point of destroying them. Flame weeders can be combined with techniques such as stale seedbeds (preparing and watering the seedbed early, then killing the nascent crop of weeds that springs up from it, then sowing the crop seeds) and pre-emergence flaming (doing a flame pass against weed seedlings after the sowing of the crop seeds but before those seedlings emerge from the soil—a span of time that can be days or weeks).

How to control weeds in a garden?

Coverings. In a domestic gardens, methods of weed control include covering an area of ground with a material that creates a hostile environment for weed growth, known as a weed mat . Several layers of wet newspaper prevent light from reaching plants beneath, which kills them.

What are the different types of weed control plans?

Weed control plans typically consist of many methods which are divided into biological, chemical, cultural, and physical/mechanical control .
