Which agricultural practice could result in lower pesticide usage?

• A. Conventional breeding techniques
• B. Genetic modification for pest resistance
• C. Increased herbicide application
• D. Soil depletion strategies

Answer: (B)

The choice of genetic modification for pest resistance is a sound agricultural practice that can lead to lower pesticide usage. By introducing specific genes into crops that confer resistance to certain pests, these genetically modified organisms (GMOs) require fewer chemical insecticides for pest management. This is because the plants are naturally able to defend themselves against insect attacks, reducing the need for external pesticide applications.

In contrast, conventional breeding techniques also aim to produce pest-resistant varieties but may not be as effective or precise as genetic modification, possibly resulting in higher pesticide use until effective resistant varieties are developed. Increased herbicide application can lead to more chemicals being used in the environment rather than less, while soil depletion strategies focus on practices that actually degrade soil quality rather than improving pest management.
