Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. The organism which is used for biocontrol is called as biocontrol agents. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
- Trichoderma is a potent biocontrol agent and used extensively for soil born diseases. It has been used successfully against pathogenic fungi belonging to various genera, viz. Fusarium, Phytophthora, Scelerotia, etc. Hence Assertion is correct.
- Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus. These viruses are excellent species-specific, biocontrol agents and have narrow spectrum insecticidal application. Hence reason is correct.
- So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
