Regarding the assertion and reason, choose the right option.
Assertion [A]: Integrated Pest Management (IPM) is a broad approach for the economic control of pests without polluting nature.
Reason [R]: IPM uses naturally occurring compounds from plants, animals, fungi and bacteria as pesticides.
Integrated pest control or management is an approach to control pests affecting agricultural productivity. Its objectives are similar to those of sustainable farming like minimising the use of chemical fertilizers and protecting the health and safety of farm workers, local communities and society in general. Thus, to meet these objectives, IPM emphasises on the growth of healthy crops with the least possible damage to the environment, and encourages natural pest control mechanisms like the use of naturally occurring compounds from plants, animals, fungi and bacteria, which can act as pesticides.
