Weeds compete with crops for water, light, and mineral nutrients. Those with broad leaves over-shadow the crops from direct light intensity and in turn reduces photosynthesis. They utilize nutrients and water in the soil thereby preventing the crops from getting them.
2. Because of their ability to grow fast, weeds can suppress growth of crops on the farm thereby reducing their development and yield.

Weed control measures

There are several methods used in weed control. They can BE classified into:
(a) Mechanical or physical method.
(b) Cultural method.
(c) Biological method.
(d) Chemical method.
(a) Mechanical or physical method

(i) Hand pulling: 1 This is the pulling of weeds by hand in the farm. Though it is efficient, but only useful in small gardens and not large farms.

WEEDS CONTROL METHODS

(ii) Hoeing: The short or small hoe is very useful in weeding. It is used to cut the weed below the crown of the plant which gives, complete destruction of the shoot system. It is effective in the control of weeds either in pasture, home garden or row crops. Hoe can be used to weed from the furrow to the top of a ridge. Its use is however on a limited and it requires plenty of labour.

(iii) Mowing: This method helps to prevent seed production in till of weeds. It removes all unsightly weed growth especially where weeds are too much for effective cultivation to take place. The method can be used to control weeds in lawns, plantation or fields. The mower is normally attached to a tractor or pulled by hand to move over the area to be cleared.

(iv) Flooding: This is done by keeping the area to be weeded Hooded up to 20 cm of water for 3 to 8 weeks. This practice kill, the weeds because they can no longer receive air for a-.piration.




(v) Heat treatment: Heal can be used in controlling weeds. For instance nursery soil is sterilized to kill all weed parts and seeds. Fire ran be used to burn dry weeds on cultivated land before cultivation starts.

(vi) Smothering with non-Living materials: Weeds can be Followed by the use of mulch materials such, as papers, hulls from rice, manure, plastic materials or cellophane. These materials help to exclude sunlight and prevent shoot growth. The weeds then become etiolated (lose chlorophyll) and die off.

(vii) Culural method: This involves the use of cultural practices of crop production to reduce the growth of weeds on the farm. Such cultural practices include
YOU CAN READ DETAILS OF CULTURAL PRACTICES HERE
i. Burning of farmland: This kills weed parts, seeds and fruits both in the soil and on the surface.
ii. Tillage: Tillage helps to expose weed parts for destruction by sun or herbicides. They can also be hand picked and destroyed.
iii. Early planting: This ensures that crops are well established before the weeds start growing.
iv. Good spacing: Proper spacing of crops helps in the reduction of weeds along the crop rows. It also makes it easy for weeding to he done.
v. Mixed cropping: Planting or two or more crops, together oil the same farmland can help to reduce the intensity of weeds on the larm
(c) Biological method
This involves the use of living plants and animals to control weeds. They include:
(i) Use of suppressive plants: Crops that grow fast and large too can be used to overshadow weeds thereby reducing their growth, Also, cover crops such as melon and legumes like groundnut can be used to control weeds on the farm.
(ii) Use of insects: This involves the use of identified insect pests weeds in controlling weeds on the farm. Insects which have been found to feed on a particular weed can be multiplied and introduced to the area to feed and destroy such weed species.
(iii) Pasturing: This involves the grazing of farm animals on weeds usually in plantations such as rubber and oil palm. Animals like i cattle, sheep or goat are commonly used in this method.
(d) Chemical method
This is the method that is used on a large scale. It makes use of chemicals in the control of weeds. These chemicals are known as herbicides. They are sprayed either on the leaves of weeds or applied to the soil. They are classified into:
(i) Selective herbicides: These are chemicals that can kill certain groups or species of plants. Example is 2, 4 -D (Dichlorophen-oxyacetic acid). They can be used in cereals, sugar cane and soya beans farms to reduce weeds.
