A biocontrol agent to be a part of an integrated pest management should be
1 Species-specific and inactive on non-target organisms
2 Species-specific and symbiotic
3 Free living and broad spectrum
4 Narrow spectrum and symbiotic
Explanation:
A biocontrol agent to be a part of an integrated pest management should be species specific, free living, narrow spectrum and inactive on non target organisms. Example - Trichoderma is a fungus. It is used as a biocontrol agent against plant pathogens. It is a free living fungus and is commonly found on the root surface.

Select the correct statement.
1 Acetobacter aceti produces citric acid
2 Saccharomyces cerevisiae is used as clot buster
3 Penicillium notatum restrict the growth of Staphylococci
4 Methanogens are found in aerobic conditions
Explanation:
Penicillium notatum is known for producing penicillin, which is an antibiotic that can inhibit the growth of bacteria like Staphylococci. This property of penicillin has been used in medicine to treat bacterial infections. - Acetobacter aceti is used for the production of acetic acid, the main component in vinegar. - Saccharomyces cerevisiae is used for industrial production of ethanol. - Methanogens are commonly found in anaerobic conditions.

The first bioherbicide developed in 1981 was based on:
1 Phytophthora palmivora
2 Phytophthora infestans
3 Bacillus thuringiensis
4 Azadirachta indica
Explanation:
Phytophthora palmivora was the first bio herbicide developed in 1981, used to control Morrenia odorant (milkweed) in citrus orchards. it was fungus based mycoherbicide. - Myco- herbicides are one of the classes of bio herbicides. This uses fungus which is parasitic to plants. This herbicide is reliable, easy to apply, easy to stores, and safe for the farmers and the crops too. Mycoherbicides are cost effective to, as they produce a huge number of spores once applied, there is no need to apply them after every crop cycle.

A common biocontrol agent for the control of plant diseases is -
1 Baculovirus
2 Bacillus thuringiensis
3 Glomus
4 Trichoderma
Explanation:
Trichoderma is a genus of imperfect fungi that produces toxins which inhibit the growth of other fungi and thus protects the plant from fungal disease. Baculovirus (Nucleopolyhedrovirus) are also used as biocontrol agents but they are used for the control of insects pests. Bacillus thuringiensis is a soil bacterium which is used as bioinsecticide. . Glomus is a fungus that forms a symbiotic relationship with plant roots and helps them to take up nutrients from the soil.
