Final answer:
True, a Getz duster is indeed used to apply small amounts of insecticide into cracks, which is a method that supports targeted pest management while minimizing environmental impact. The inclusion of integrated pest management strategies such as pest resistant cultivars and interplanting further supports environmentally sustainable practices.
Step-by-step explanation:
The statement that a Getz duster is used to apply small amounts of insecticide into cracks is true. This type of application is crucial in pest management, especially in agricultural settings, because it allows for targeted control with minimal impact on non-target species and the environment. For example, when managing pests on cotton plants, the application of pesticides might be focused on specific parts of the plant rather than indiscriminate spraying. This practice preserves the natural enemies of pests like the bollworm.
Other sustainable pest control strategies may include the use of pest resistant cultivars, interplanting with other crops, and using pheromones to trap adult pests. However, it is essential to recognize the risks associated with older, more persistent insecticides like DDT, which, despite its effectiveness against malarial mosquitoes, has been found to have serious environmental and health drawbacks due to its resistance to breakdown.
