What should be a priority when selecting pesticides for use?

When selecting pesticides for use, the primary consideration should be their effectiveness against the target pests. This is crucial because a pesticide that does not effectively control the intended pest will not fulfill its purpose, leading to potential damage, increased pest populations, and wasted resources. The effectiveness ensures that the treatment will achieve the desired outcomes, such as reducing pest populations to manageable levels and minimizing harm to beneficial organisms.

While cost-effectiveness is important for budgeting and financial planning, it should not overshadow the necessity of the pesticide effectively addressing the particular pest problem at hand. Popularity in the market and the level of advertising often reflect trends rather than efficacy, which can mislead users into choosing products that might not be suited for their specific needs. Prioritizing effectiveness ultimately supports successful pest management strategies and contributes to sustainable practices in pest control.
