North Carolina Pesticide Application Practice Test

The presence of '3 E' on a nematodes label indicates that there are 3 pounds of active ingredient per gallon of emulsified concentrate. This notation helps users understand the concentration of the product they are using. It is crucial for ensuring the proper dosage for effective pest control. This specification allows applicators to efficiently calculate how much product to mix based on the size of their application area and the severity of the pest problem.

In contrast, the other options do not accurately reflect the meaning of '3 E.' For example, '3 years of effective control' refers to a timeframe rather than a measurement of concentration. '3 easy steps to apply' suggests a simplicity in application rather than a quantitative measure. Lastly, '3 types of pests it targets' pertains to the range of effectiveness of the product and does not relate to the concentration of active ingredients within the formulation. Understanding these distinctions helps ensure appropriate usage of pesticide products in pest management practices.
