Distance Learning Course in Plant Pathology Science

  • Become skilled at diagnosing and understanding plant diseases.
  • Enhance your career or job prospects in horticulture or farming
  • Improve your ability to grow plants
  • Understand the science of plant disease

Plant production is reduced significantly every year, due to pathological problems. To control these problems is to increase productivity, and for the horticultural business; that means increased profit margins.

PLANT PATHOLOGY IS NOT simply a study of pests & diseases. Some pests are in fact not pathological problems, and there are pathological problems which are not pests or diseases.

PLANT PATHOLOGY is about problems in plants caused by physiological damage or irritation at a cellular level. It is concerned with problems which affect parts of the plant cell, leading to malfunctions in the normal processes which occur
