Explain the importance of bio pesticides in organic farming.
Answer»
By using bio pesticides, soil pollution is minimized. Otherwise by using chemical pesticides and fertilizers there is large scale soil pollution.
When chemical pesticides are used in agriculture, there is contamination of soil by fluoroacetamide – like chemicals.
These are harmful to other plants, animals as well as for-human beings. They may cause skin diseases in humans.
By using bacterial and fungal toxins the pests and pathogens can be destroyed. Such toxins are directly incorporated in the plant materials. E.g. Spinosad is a biopesticide produced as a by-product of fermentation.
