Biocontrol Agents and Biofertilisers

Name: Biocontrol Agents and Biofertilisers
Author: StemPy Lab

How a farmer can protect a crop and feed the soil without a factory made chemical. Ladybirds, Bacillus thuringiensis, Trichoderma and baculoviruses against pests, then Rhizobium, Azospirillum, Azotobacter, mycorrhiza and cyanobacteria as biofertilisers. The last lesson sorts out which microbe does which job.

Lesson 1about 30 min
Microbes that control pests
Chemical pesticides harm people and animals and pollute the soil and the water. Biological control uses living things instead: ladybirds and dragonflies, the spores of Bacillus thuringiensis, the fungus Trichoderma and baculoviruses. Each one attacks a narrow range of pests, so it fits into integrated pest management.

Lesson 2about 30 min
Microbes that feed the soil
Biofertilisers are living organisms that enrich the soil. Rhizobium lives in the root nodules of legumes and fixes nitrogen. Azospirillum and Azotobacter fix nitrogen as free-living bacteria. Mycorrhizal fungi such as Glomus bring phosphorus to the plant, and cyanobacteria fix nitrogen in paddy fields.

Lesson 3about 25 min
Which microbe does which job
A good revision of this chapter is a list of jobs and the microbes that do them. This lesson gathers every organism of the chapter in one table, sorts them by group and by job, and ends with the traps that questions use: the same genus with two jobs, and look alike names.
