Solution
The correct option is C B and D
A variety of pests (insects) and pathogens (viruses, bacteria etc.) attack agricultural crops and destroy them, leading to huge crop losses.
To control these pests and pathogens, farmers have been indiscriminately using chemicals (pesticides and insecticides) to destroy them. But these chemicals are extremely toxic to humans and also cause pollution. Besides killing the target pests, they also kill other non-target insects.
Therefore, nowadays, biocontrol methods are being used to overcome the problem of chemical pesticides.
Biocontrol refers to the use of biological methods for controlling plant diseases and pests rather than the use of chemicals. For example: Ladybird beetles are biocontrol agents that are used to get rid of aphids (pests). The ladybird beetle is a beneficial predatory insect that feeds on aphids.
Another excellent example of a biocontrol agent is baculovirus. These viruses are pathogens that attack arthropods (majorly insects).
The baculoviruses which belong to the genus Nucleopolyhedrovirus are majorly used as biocontrol agents against insect pests.
They are species-specific and narrow spectrum insecticidal applications which means that they target only specific species.
They are effective in eradicating the target organisms but do not harm plants, mammals, birds, fish and other non-target organisms.
Therefore, the statements B and D are correct.
