Which of the following is considered a cultural control practice?

Using resistant crop varieties is considered a cultural control practice because it directly involves selecting plant species or varieties that possess natural resistance to specific pests or diseases. This strategy falls under the umbrella of integrated pest management (IPM), where the objective is to reduce the dependency on chemical controls and minimize pest populations through proactive measures.

By opting for resistant varieties, growers can enhance the resilience of their crops, making them less susceptible to the impacts of pests and diseases. This not only helps in sustaining crop health but also promotes environmental health by reducing the need for chemical interventions, which can have unintended negative effects on the ecosystem.

In contrast, regularly applying chemical fungicides is more associated with chemical control methods. Over-fertilizing the soil can lead to nutrient imbalances and environmental issues rather than serving as a control strategy for pests. Ignoring pest reports reflects a lack of awareness or management strategy, which does not align with any proactive or cultural practices aimed at pest management.
