PURPOSE OF THE UNIT STANDARD 
The learner will be able to control weeds, pests and plant diseases chemically in an agricultural field using a knapsack sprayer.

A person credited with this unit standard is able to:
  • Demonstrate an understanding of chemical control for weeds, pests and plant diseases.
  • Prepare sprayer and chemicals for chemical control procedures
  • Apply chemicals with a knapsack sprayer
  • Perform end of chemical control procedures

    Range: Crops may include but are not limited to sorghum, maize, groundnuts, sunflower, beans, soya beans, sugarcane, wheat, rye, barley, cotton and potatoes.

    Chemicals refer to herbicides, a poisonous substance that destroys weeds, pests and plant diseases.
