Question

What is IPM? Give an example of bio insecticides and bio herbicides and how do they help in pests control.

Answer 1

Integrated pest management (IPM) is also known as integrated pest control (IPC) is a broad-based approach which integrates practices for economic control of pests. The aim is to suppress pest populations below the economic injury level (EIL).

Complete step by step answer:
Pests are animals that affect adversely on human activities and prove harmful to them, especially destroying the practices at agricultural level, that is in a crop field different types of pests destroy different types of crops.
To get rid of the problems created by these pests farmers need to practice pest control methods to produce better quality and high yield of the crops.
Integrated Pest Management (IPM) also known as Integrated Pest control (IPC) is an approach that works to control pests at economic level.
It works by first monitoring, that is, the inspection and identification and after that the establishment of economic injury levels.The technique uses different actions such as cultural, biological and chemical controls.
cultural controls include physical barriers, biological controls include adding and conserving natural enemies and predators of the pests while chemical controls include the pesticides and insecticides such as DDT, etc.
Bio-insecticides are small insects or microorganisms that are naturally present in the environment to control other insects from destroying the crop fields.
For example, ladybugs and praying mantis combat scale insects for aphids which feed on plant sap.
Bioherbicides are the organisms that control or destroy unwanted plants also known as weeds without harming useful plants.
For example, growth of eichhornia crassipes is controlled by cercospora rodmanii and alternaria eichhorniae.
In this way growth of pests and weeds can be controlled naturally.

Note:
IPM promotes sound structures and healthy plants. IPM promotes sustainable bio-based pest management alternatives. It reduces environmental risk associated with pest management by encouraging the adoption of more ecologically benign control tactics .
