Question

how should chemical pesticides be used in integrated pest management? for complete pest extinction liberally and frequently sparingly, with the aim of controlling pests as a first option

Explanation:

Integrated Pest Management (IPM) emphasizes using chemical pesticides as a last resort or sparingly, focusing on pest control (not extinction) and combining other methods. The option "sparingly, with the aim of controlling pests" aligns with IPM principles, as IPM prioritizes non - chemical methods first and uses chemicals minimally to manage pest populations, not eliminate them entirely, nor uses them liberally/frequently or as a first option.

Answer:

C. sparingly, with the aim of controlling pests (assuming the options are labeled A - D with A: for complete pest extinction, B: liberally and frequently, C: sparingly, with the aim of controlling pests, D: as a first option)
