INM | know more about Integrated pest Management and its Methods!

Integrated pest Management ( INM) is one of the essential steps towards maintaining the sustainability of the environment. It is an effective approach to pest management that relies on a combination of various practices that do not harm the environment.

INM practices include –

Biological control –
Biological control is the use of natural enemies—predators, parasites, pathogens, and competitors—to control pests and their damage. Invertebrates, plant pathogens, nematodes, weeds, and vertebrates have many natural enemies. Eg – The larvae of many hoverfly species principally feed upon aphids, Species used to control spider mites include the predatory mites Phytoseiulus persimilis, Neoseilus californicus etc.

Cultural controls –
Cultural Controls destroy the pests or prevent them from causing economic loss. Cultural controls are practices that reduce pest establishment, reproduction, dispersal, and survival. For example, changing irrigation practices, Mechanical tilling or Ploughing, Hand pulling of the weed with all its roots etc.

Mechanical and physical controls-
Mechanical and physical controls kill a pest directly, block pests out, or make the environment unsuitable for it. Traps for rodents are examples of mechanical control. Physical controls include mulches for weed management, steam sterilization of the soil for disease management, or barriers such as screens to keep birds or insects out.

Chemical control –
The use of pesticides is done in Chemical Control. In IPM, pesticides are used only when needed and in combination with other approaches for more effective, long-term control. Pesticides are selected and applied in a way that minimizes their possible harm to people, nontarget organisms, and the environment.
