Final answer:
The Signal Word on a pesticide label indicates the pesticide's toxicity level. It is a critical piece of information to understand for safe pesticide handling and to prevent pesticide poisoning, which can have severe symptoms.
Step-by-step explanation:
The part of a pesticide label that gives you an indication of the toxicity of the pesticide is B. The Signal Word. The Signal Word can be either 'Danger' (for pesticides that are highly toxic), 'Warning' for moderately toxic, or 'Caution' for those with lower toxicity levels. These words provide a quick reference to the potential danger of the chemical to humans and animals.
It is important to understand these Signal Words when handling pesticides, as they are a key component in preventing pesticide poisoning. Pesticide poisoning can take various forms, depending on the type and amount of pesticide involved. Some common symptoms include headaches, dizziness, nausea, and, in severe cases, difficulty breathing or even death.
Widely Used Herbicides
There are several kinds of widely used herbicides, including contact, systemic, pre-emergent, and post-emergent herbicides. Each type works differently and is used for specific weed control purposes. For example, contact herbicides kill only the plant tissue they touch, while systemic herbicides are absorbed and move within the plant to kill it.
