A 'Contact Pesticide' is a type of pest control product that affects organisms upon direct contact. These pesticides work by coming into contact with the pest's body, either through physical contact or through ingestion, leading to the pest's elimination. This direct mode of action differentiates contact pesticides from other types of pesticides that may require ingestion to be effective or rely on long-distance pest control mechanisms.

In comparison, the other options are not accurate definitions for a 'Contact Pesticide':

- Option A, a pesticide that must be ingested by pests to be effective, describes a systemic pesticide.

- Option B, a pesticide applied through irrigation systems, describes a method of application rather than the mode of action of the pesticide.

- Option D, a pesticide that is effective for long-distance pest control, does not specifically describe the characteristic of acting upon direct contact, which is the defining feature of a contact pesticide.
