UNDERSTAND PLANT HEALTH

  • Identify Problems
  • Determine Appropriate Responses

There are thousands of possible causes which can contribute to a plant's problems.

More often than not, there are several factors involved. Minor diseases or environmental problems may weaken the plant, making it susceptible to some more major (obvious) disorder. When you inspect a plant for problems, you should systematically consider all of the things which might possibly be going wrong. This course provides the foundation for inspecting diagnosing and treating all types of problems.

This subject develops a firm understanding of plant health, the systematic identification of health problems in plants, and the techniques for control of those problems.

Government, nursery and private positions are more demanding than they ever were; employers are becoming increasingly selective choosing personnel with broad horticultural knowledge and less emphasis is placed on the 'learn on the job' approach of years gone by. Education is imperative if you expect to compete in this field and those that have the knowledge will also have the best chance of reaping the rewards.

A sick plant may have one or several causes at the same time.

Diagnose different problems (ie. pests or diseases), documenting the problem on a standard pest/disease review worksheet.

Describe different ways to control pests and diseases, including:

  • Application of chemicals
  • Plant selection
  • Companion planting
  • Cultural techniques (i.e. improving ventilation, improving drainage)
