Which technique is NOT a part of field monitoring in IPM?

The technique that does not belong to field monitoring in Integrated Pest Management (IPM) is implementing chemical control. Field monitoring involves methods that help assess the presence and levels of pests, beneficial organisms, and the overall state of the environment in relation to pest management.

Collecting soil samples, visual inspections, and setting up pheromone traps are all integral components of monitoring practices. Collecting soil samples can provide valuable information about soil health and pest presence, visual inspections allow for direct observation of crop conditions and pest activity, and pheromone traps are used to capture specific pests or monitor their populations.

In contrast, implementing chemical control refers to the use of pesticides or herbicides to manage pest populations, which is an action taken after assessing pest presence rather than a method of monitoring. It falls under the management strategies aspect of IPM rather than the observational and data-collection efforts that characterize field monitoring.
