CONTENT OF THE LESSON 

LESSON ONE – INTRODUCTION 

Weeds are unwanted plants growing in the farm and other places.

Weeds compete with the grown plant for food, water, air and space, such that the wanted plant may eventually die.

The common of weeds are – elephant grass, guinea grass, spear grass, giant star grass, bahama grass, carpet grass and pig weed.

 

 

CONTROL MEASURES – HOW TO CONTROL WEEDS 

Biological Control 

This process involves using animals to feed on the weeds on a farm of tree crops that are fully grown, such as a citrus orchard, rubber plantation and palm plantation.

One disadvantage of this method is that the animals may also eat and destroy the wanted plants in the process.

 

Cultural Control 

Cultural control is the removal of weed by hands, cutlass or hoe.

It involves uprooting weeds with hands, cutlass or hoe.

This is also called manual control.

A chemical is a man-made liquid or powder used for controlling or killing weeds.

It is also used for controlling or killing pets and diseases. This control is called weedicides.
