In plant disease control, the latest trend is
1 Chemical control
2 Mechanical control
3 Biological control
4 None of these
Explanation:
Biological control is biological method of controlling plants diseases and pests. Using of biocontrol agents is the latest trend because:- - They do not eradicate pests and pathogens, but keep their levels manageable. - They are non toxic and non-biocidal. - They do not kill useful organism and do not pollute soil, fruits and vegetable.

When a natural predator (living being) is applied on the other pathogen organism to control them, this process is called :
1 biological control
2 genetic engineering
3 artificial control
4 confusion technique
Explanation:
The natural method of pest and pathogen control involving use of microbes and insects (Which are natural predators and pests) is called biocontrol or biological control. For example- Lady bird beetle which feeds on aphids is used in agriculture for aphid control.

Select the correct group of biocontrol agents.
Fungus Trichoderma, Baculoviruses (NPV), and Bacillus thuringiensis (Bt) are used as biocontrol agents and as a tool to produced recombinant proteins. Trichoderma is a fungus and biofungicide, it is used for seed and soil treatment. Bacillus thuringiensis is used in agriculture for the control of insect pest. _Baculoviruses are pathogens that attack insects and other arthropods. - Oscillatoria, Rhizobium, Nostoc and Azospirillum are used as biofertilizer. - Tobacco mosaic virus and Aphid are used as agricultural pests.

Which of the following can be used as a biocontrol agent in the treatment of plant disease?
1 Chlorella
2 Anabaena
3 Lactobacillus
4 Trichoderma
Explanation:
Biocontrol agents includes microbes and insects that control the plant diseases and pests. They control harmful pests such as weeds, parasitic nematodes and other pests. - Trichoderma species belongs to the fungal class Ascomycetes, they are found abundantly in soil. It is used as biocontrol agent in the treatment of plant diseases. It is commonly used against infection - causing parasites in pulses, cotton and onion. They protect the roots of the plants from pathogenic infections.
