$\huge\boxed{ \fcolorbox{blue}{yellow}{answer}}.$

4) Nostoc, Azospirillium, Nucleopolyhedrovirus.

Answer 2

Bacillus thuringiensis, Tobacco mosaic virus, Aphids, Trichoderma and Baculovirus are the correct group of biocontrol agents.

Step by step explanation:

• Biocontrol agents are the natural enemies to monitor plant threats such as parasitism, predation and other processes.
• They plays crucial role in regulating plant pests such as parasitic nematodes, insects, invasive nematodes, and mites.
• Fungs Trichoderma, Baculoviruses (NPV) and Bacillus thuringiensis are considered as a biocontrol agents.
• The biofertilisers are Rhizobium, Nostoc, Azospirillum and Oscillatoria.

Hence, correct option is 1
