The Use Of Farm Chemicals
Gbogbo ọrọ náà
The chemicals that protect crops, herbicides, insecticides and fungicides, are powerful poisons. The very property that makes them kill weeds, pests and diseases also makes them dangerous to the farmer, to people nearby, to livestock and to the environment. Used carelessly they can poison the user, contaminate food and pollute rivers; used carefully they are safe and effective.
In this lesson you will learn how to handle farm chemicals safely from start to finish: the protective clothing to wear, how to dilute and mix correctly, the precautions to take before, during and after spraying, and how to clean equipment without polluting water. You will also learn why chemicals must be stored in a locked, well-ventilated store, kept in their labelled containers, and why toxic and flammable products need special care.
