Regardless if you are a farmer, an oil worker or a person working in an office, that LABEL affixed by law on that chemical container is in place not just by law and to make it look pretty, it is in place to teach you the risks and how to use or apply that chemical. Here is a prime example of what every worker should be thinking: What Information Is Contained On A Chemical Label?
A chemical label contains detailed information regarding the product. The label itself is a legal document, which under legislation, must be adhered to at all times. Operating outside the instructions on the chemical label is illegal, and can result in hefty penalties, including imprisonment. It is therefore important to read the label carefully before every application, particularly for those new to farming and for those who are using a pesticide for the first time. As an example we will use a common herbicide label to highlight the important information it contains. Roundup CT (Glyphosate) is a common herbicide used everyday by people from home gardeners to farmers however, some users know very little about the product. And when you need more DATA alway turn to the product Safety Data Sheet if not printed or produced because it want to take room on your shelf or add to to your paper work it is filled the SAFETY RELATED USEFUL DATA!
- Pesticide: A chemical formulation that controls pest activity. Pesticides include herbicides (weeds), insecticides (insects), and fungicides (fungal diseases).
- Mode of Action: All chemicals are grouped into families or classes, according to their mode of action. Mode of action classes chemicals according to the site or enzyme within a plant, disease, or insect that the active constituent works on. Mode of action is particularly important for resistance management.
- Resistance: Within any pest population, there are individuals that are naturally resistant to the active constituent. Resistance occurs when these surviving pests are subjected to the same mode of action repeatedly; resistant hosts survive and multiply, causing a resistant population.
- Active Constituent: The biologically active part of the chemical present in the formulation.
- Chemical Formulation: Is a process that involves mixing the active constituent with other materials to make it suitable for use in controlling pests. Common additives to the active constituents include, emulsifiers and stabilisers.
- Surfactant (wetter): Is a “surface active agent” which serves to lower the surface tension of the water in the spray solution. This enhances spray coverage, as a droplet with low surface tension, spreads out and covers a greater area of leaf.
- Compatibility: The ability of a pesticide to be mixed with another without causing a reduction in activity.
- Tank Mixing: The practice of adding two or more pesticides together to control multiple pests, with the one spray application. Compatibility is very important when you are tank mixing pesticides.
- Plant-back Period: Some herbicides have a period of time (days, weeks or even months) which must elapse before the next crop can be planted back into the treated area. Residual herbicides can have lengthy plant-back periods for particular crops, which must be adhered to prevent crop damage.
- Withholding Period: The period of time which must elapse between treatment of a pesticide, and the harvest, or selling of the treated product. The withholding period is there to prevent higher than acceptable pesticide residues in food products.
