LEARN WEED CONTROL
This course assumes a basic knowledge of weeds, and from there develops your ability to diagnose and treat problems associated with weeds in gardens, amenity landscapes, on farms and in natural areas.
There are many different ways of controlling weeds, and literally thousands of different weed species which might need controlling. It is always important to use the appropriate treatment for the weed(s) in question. Young weeds are far easier to control than older ones. Some chemicals, for instance will effectively kill certain weeds when they are in the early stages of growth, but will not control other types of weeds. You may need to be able to distinguish between types of weeds to determine whether the chemical will or won't work.
Over eight lessons you learn about both chemical and non-chemical control methods (mulching, burning, mowing), the use of spray equipment and safety procedures which should be followed.
Duration: 100 hours
The course is divided into 8 lessons as follows:
1. Weed Identification: review of the system of plant identification, general characteristics of the weeds, further information, contacts, etc.
2. Weed Control Methods: practical research on management of weeds, understanding terminology and the use of mulches
3. Chemical Weed Control: review of commercial and domestic herbicides, determining what differentiates them, their availability and use.
4. Weed Control In Specific Situations: understanding weed control strategies for particular situations, accessing first hand information about weed control from industry leaders and determining a weed control program for five different sites.
5. Safe Chemical Application: reviewing what types of chemicals and application methods are used in the industry and the required safety procedures for the handling and administrating chemical herbicides.
6. Non-Chemical Weed Control: determining any detrimental effects chemical herbicides have on the environment, reviewing non-chemical applications and their effectiveness.
7. Dealing With Specific Weed Control Problems: looking at current industry practices for weed control and the effects on the environment, in relation to specific weed control problems.
8. Developing A Major Weed Control Program: a practical lesson where the student can fully demonstrate their understanding of weed control by devising a weed management plan for a designated area.

What is a Weed?
A weed is any plant that is growing where you don't want it. A weed will compete with your desired plants for light, space, water and nutrients. A plant could also be a weed because of a particular characteristic; it could be poisonous to stock or humans, it may act as a host plant for pests and diseases (of both other plants and/or animals), it may have damaging roots, or it could cause allergies. Any plant has the potential to be a weed.
There are many different ways of controlling weeds, and literally thousands of different weed species which might need controlling. It is always important to use the appropriate treatment for the weed(s) in question. Young weeds are far easier to control than older ones.
Steps in Controlling Weeds
Know what weed or weeds you are dealing with.
Know how those varieties grow, and what conditions they do and don't tolerate.
Create conditions which weeds don't like.
You need to consider whether you want to kill or just control the weeds. When you know these answers you can consider which method is best for your situation.
This course will show you a range of ways of controlling weeds -some natural, some not.
Reasons to Study This Course
This course covers all aspects of weed control from slashing to burning, and chemicals to organic methods. It helps students with identification regardless of which country you live in, and assists you in devising programs of weed control on different sites throughout the year. The course is a great companion to other horticulture courses but may be studied by itself. It will be of particular interest to people working in the following fields:
- Garden Maintenance
- Land Management
- Parks & Gardens
- General Horticulture
