Which of the following methods is useful for early detection of cointegration pests?

Monitoring with sticky traps is a valuable method for the early detection of cointegrating pests because these traps help capture and monitor pest populations in a specific area. Sticky traps work by trapping insects that are attracted to certain colors or scents, allowing for direct observation of the types and numbers of pests present. This early detection is crucial for implementing timely pest control measures, potentially preventing larger infestations that could damage crops or plants.

While the other methods may contribute to pest management or prevention, they do not serve the primary function of early detection. Time-release fertilizers primarily focus on supplying nutrients over time, aromatic repellent plants are designed to deter pests rather than detect them, and growing companion plants can provide benefits such as pest attraction or improved growth but do not aid in identifying pest presence. Thus, monitoring with sticky traps stands out as the most effective choice for early detection.
