According to IPM practices, how should healthy plants be managed?

The management of healthy plants according to Integrated Pest Management (IPM) principles emphasizes the development of plant varieties that are resistant to pests and capable of withstanding pest pressures. This approach involves selecting and breeding plants that possess natural defenses against common pests, thereby reducing the need for chemical interventions and minimizing potential damage.

By focusing on producing disease-resistant and pest-resistant plants, growers can create an environment in which healthy plants can thrive with lower risk of infestation. This proactive strategy enhances overall plant health, reduces reliance on pesticides, and contributes to sustainable agricultural practices.

In contrast, the other options do not align with IPM principles. For example, removing healthy plants at the first sight of pests can lead to unnecessary waste and may not be an effective long-term solution. Cultivating plants solely with chemical fertilizers can neglect holistic plant health, which is key in IPM. Ignoring healthy plants is also not advisable; continual monitoring and management are essential even for those that appear unaffected. Thus, producing plants that can resist and withstand pest pressures is a fundamental aspect of managing healthy plants in IPM.
