Question
Chapter 20, Problem 5CHQ
Interpretation Introduction
Interpretation: The reason to consider making your own herbicide instead of buying a synthetic weed killer.
Concept Introduction: Strong weed killers attack the root of the weeds. It travels down the root to the underground system of the weed, and prevents it from growing thus killing the weed systematically from inside out. Some strong weed killers may be slow to act but they are perfect for killing difficult and perennial weeds. After application of the weed killer, the weed control takes 7 to 10 days to show its result. Many weed killers are rendered ineffective die to rain as they tend to get washed away.
