Among the names of a pesticide, which one is most often missing from labeling?

The most often missing name from pesticide labeling is the common name. The common name is a simplified name for a pesticide that is widely recognized and used by the general public and professionals alike. While the trade name and brand name are prominently displayed on product labels for marketing purposes, the common name may not always be included, especially in consumer-targeted products.

The trade name is typically the name created by the company for marketing, while the brand name may refer to a specific line of products from that company. These names are important for consumers because they help identify the product they are purchasing. Conversely, the chemical name, which refers to the exact chemical composition of the pesticide, is generally included on the labeling but can be complex and less accessible to the average user.

Thus, while the trade, brand, and chemical names are often present on pesticide labels, the common name is frequently less emphasized or absent, leading to potential confusion among users who may not be familiar with chemical or technical terminology.
