Weed Control 100 Hours Certificate Course
Learn About Weed Control
A weed is any plant that is growing where you don’t want it. Any plant has the potential to be a weed.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, if it acts as a host plant to pests and diseases (of both other plants and/or animals), if it has damaging roots, or if it causes allergies.
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.

Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
- Choose Your Learning Method
You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
- Tutor Allocation
Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
- Feedback and Assignments
Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
- Set Tasks and Self-Tests
Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead.
Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
- Design Your Own Qualification
ADL offers students the flexibility to self-design their own qualification – bundling together a combination of 100-hour modules into a qualification higher than a certificate.

For a 100 hour module many students will take up to 3- 6 months, others take less time and some are even longer. It’s all up to you. There is no pressure to complete or deadline to finish. Naturally, longer courses will take more time.
Q. What learning formats are there?
A. Your enrollment comes with the Online Classroom study option by default. For a small additional cost you also have the options of USB or Correspondence.
USB: Your course is sent to you on a USB stick, so that you can carry it in your pocket. Ideal for those with unreliable internet connections. This option is an additional £5/module
Correspondence: You download the course content and then print your own copy to your requirements. You can then bind the lessons to suit your needs.
Q. Assessment – how does it work?
A. For each 100 hour module you are assessed by assignments (at the end of each lesson) and a final one and a half hour exam (or you may elect to complete a project instead of sitting the exam) – the choice is yours – you sit for the exam in your own location, or you can visit us in Canterbury, England to sit the exam if want to. Exam fees are included in the tuition fee you paid. You can read more about the examination process here. At the end of each lesson, there is an assignment. You submit it to the academy who then submits it to the tutor for marking, comments and feedback. Our policy is to have a grade for you within 5 to 7 days.
Q. How many assignments do I need to complete for each module?
A. At the end of each lesson, there is an assignment – so if a course has say, 10 lessons there would be 10 assignments. The number of lessons per module varies from module to module. See the course content from our website for further details.
Q. When do I have to hand in my first assignment?
A. There is no deadline for handing in the first assignment. Submit when you are ready. There are some students who hand in assignments within the first couple of weeks of enrolment – while there are others who submit their work 6 months later. It’s all at your own convenience to suit you. Everyone has different work and home commitments and we cater to these needs.
Q. I am having difficulty attending workshops/industry meetings, what can be done?
A. If your course requires attendance at workshops, conferences, or industry meetings; alternative arrangements can be made in your country; however, there may be an additional expense. We can appoint an appropriately qualified person anywhere to work through curriculum documentation supplied by us, to satisfy the requirements set down in a course.
Q. What qualification will I receive?
A. For individual modules, you would receive a Certificate (providing you complete all assignments and the exam). If you just want to complete the assignments only, then a Letter of Achievement would be awarded. For more details on qualifications awarded please click here.
Q. Is there a next level to progress to?
A. Yes – you can progress from one module to a combination of many modules and to higher qualifications i.e. Advanced Certificates, Diplomas and Higher Advanced Diplomas. Read more about course levels here.
Q. Can I customize my diploma/higher qualification?
A. Not all educational institution’s certificates /diplomas meet everyone’s needs. The opportunity to design your own diploma at the Academy (subject to our approval) is an added bonus, not found at other colleges. It’s a very popular option and widely used by many students. You quite simply choose the appropriate number of related modules needed to complete the qualification and submit them to us for approval as a custom diploma.
Q. What do I get when I complete the course? Will I receive a transcript?
A. At the completion of a 100-hour Certificate course and providing all assignments and exam have been completed, you will receive a Certificate and Transcript. The Transcript will list your GPA. Each 100-hour module is worth 3 credit hours.
Q. Do I have to sit for an exam?
A. Exams are optional but need to be undertaken in order to receive the Certificate or higher qualification. Exams are one and a half hours long. You appoint an adjudicator (subject to our approval) to supervise the exam. You sit for the exam in your own location. Its that simple.
Q. I don’t cope well with exams – what can I do?
A. If you feel you don’t cope well with exams you may elect to undertake a Project (set by the tutor) instead of sitting the exam. Many students prefer this option as they find researching the material for the project sharpens their research skills.
Q. If I don’t sit for the Exam do I still get a qualification?
A. If you don’t sit for the exam but complete the project alternative, you will still receive your endorsed qualification. If you don’t sit for an exam or complete a final project, providing you have completed all the assignments you will be awarded a Certificate of Achievement.
Q. Do I have to sit for the exam at the Academy?
A. No – whilst you are more than welcome to come to our location in Canterbury, U.K. and sit the exam in our classroom; the more popular option is to sit for the exam in your own location. You appoint an adjudicator to supervise the exam. Click here for more information on that process.

Excerpt From The Course
WEEDS IN TURF
As previously mentioned, weeds occur in turf when one or several of the following conditions/situations are present: environmental stress, damage by pests, poor cultural practice and heavy wear from vehicles or foot traffic. Along with this, anything else that reduces the general health and vigour of turf plants will make it easier for stronger growing weed plants to invade the turf.
Methods of Controlling Weed Problems in Turf
Stop the spread of weed seeds. Weeds can be brought in by the wind, on dirty shoes, on vehicles, in soil, in stolons, sprigs or plugs being transplanted, on tools, by animals, in manure or straw. Be mindful of these things and try to avoid bringing weed seeds into your turf areas.
Many weeds need to grow tall to seed. Mowing to prevent seeding will break the lifecycle on annual weeds (seed has not been set, so after plants die at the end of a season, there is no self-seeding of new plants in the next season).
- Hand Weeding
This is most effective against broad leaved annual weeds. It is time consuming, and for many weeds which will re-grow from a tiny piece of root, it is not sufficiently effective to make any real long term difference.
Contact weedicides (herbicides) kill only the parts of the plant to which they are applied (ie. if they only touch the top half of a leaf, they only kill that top half, and the bottom half of the leaf remains alive). Contact weedicides, used to kill leaf, above ground growth on some annual weeds in turf are: Paraquat, Cacodylic acid (synonym dimethylarsinic acid) (the latter is not licensed in UK and Europe).
Systemic weedicides will be absorbed into plant tissue and carried throughout the entire plant, (a process known as translocation), killing all parts of the plant. Typical systemic weedicides are Roundup (active ingredient Glyphosate): 2,4-D and Mecoprop.
Pre-emergent weedicides kill weed seeds as they start to germinate. They can be applied to an established turf to prevent weed seeds germinating in that turf. Some common pre-emergent weedicides which can be used in turf are benefin: bensulide: lead arsenate and siduron (none of these are licensed in UK): DCPA (DCPA is licensed under the name of chlorthal or chlorthal-dimethyl in UK): ethofumesate.
Selective weedicides are those which kill one type of plant without affecting another type of plant. In turf, certain chemicals can be used to kill some types of weeds in an established lawn, without affecting grass: e.g. 2,4-D: 2,4-D+dicamba: dicamba: MSMA (MSMA is not licensed in UK)
Chemical fumigation can be used to completely sterilize an area, killing weed seeds and ALL plants in an area. After fumigation, the site is generally rested for 3 days or more to get rid of all chemical residues before replanting the turf.
Flame guns can be used to burn weeds out in spot control. Burning is more applicable for control of weeds on fence lines and other areas adjacent to turf (where weed seeds come from).
- Nutrition Management
By changing the situation in the soil with respect to the soil nutrition conditions can be made more favourable for the preferred turf grass plants and less favourable for the weeds: e.g. Onion Grass (Romulea rosea) is fed with superphosphate which favours turfgrass growth but is unfavourable to onion grass growth.
