In contrast, those pollutants which cannot be broken down into simpler, harmless substances in nature, are called non-biodegradable pollutants. For examples: Metal articles like aluminum cans plastics, polythene bags, insecticides, pesticides, DDT. So, the correct option is (D).

Why biopesticides are better than chemical pesticides?

-Biopesticides are preferred over chemical pesticides because they do not contaminate the environment. The chemicals in chemical pesticides are extremely toxic and harmful to the environment. Not only this but they are also harmful to animals and humans if they ingest such crops.

Trichoderma: A biopesticide with multiple modes of action and more besides. Trichoderma is a fungal group which contains a wealth of species used as commercial biopesticides. It is one of the most commonly used microbial biopesticides, with nearly 200 commercial products in the Americas, Europe, Asia and Africa.

What are the applications of biopesticides?

Biopesticides are in high agricultural demand due to their non toxic and eco-fiendly characteristics as compared to chemial or synthetic pesticides… The biopesticides are used as microbial biological pest control agents who applied in farming processes to replace chemical pesticides.

What are the objectives of biopesticides?

Biopesticides exhibit different modes of action against pathogens such as hyperparasitism, competition, lysis and predation [8] . Plant growth promoting rhizobacteria protect plants from biotic and abiotic stresses and they also enhance plant growth and enhance formation of root hairs [9] .

Which microbes are considered as biocontrol agents?

Other than insects, microbes are also used as biocontrol agents. These microbes include bacteria, fungi, viruses, and protozoans. Microbes act as biocontrol agents in three ways, either they cause diseases in the pests or compete with them or kill them.

Why bacteria is used as bio control agent?

Bacteria, fungi and viruses can all act as biocontrol agents due to the large diversity of target species and the variety of methods of action. Important examples of microbial biocontrol agents include Bacillus thuringiensis, fluorescent pseudomonads and Beauveria bassiana.
