New Jersey Pesticide Core Applicator Practice Test

A pesticide that is absorbed in one part of a plant and transported to another part is known as a systemic pesticide. Systemic pesticides work by entering the plant's vascular system, allowing them to be moved throughout the plant. This characteristic is particularly beneficial for controlling pests that feed on the plant's tissues because the pesticide can effectively target pests at various sites, including leaves, stems, and roots.

In contrast, contact pesticides only act on the surfaces where they are applied and do not penetrate the plant. Volatile pesticides are designed to evaporate quickly into the atmosphere rather than being absorbed by plants. Residual pesticides remain active on surfaces for a certain duration, but they do not get absorbed and transported within the plant. Understanding the nature of systemic pesticides is crucial for effective pest management and ensuring safety when applying chemicals in various agricultural settings.
