IPM in India

Integrated Pest Management (IPM) in India: Features, Benefits, and Sustainable Agriculture Practices

The promotion of Integrated Pest Management (IPM) in India was started as a Central Sector Scheme in 1991 by the Ministry of Agriculture, Department of Agriculture & Cooperation, Government of India. In the country, it is considered a major ecological approach towards pest management in agriculture. It aims at combining all pest control measures to keep pest populations below the Economic Threshold Level (ETL).

As a system of crop protection, IPM is an economically justified and sustainable programme. It ensures maximum agricultural productivity without major adverse environmental impacts. IPM includes a schedule of practices such as cultural, mechanical, biological, and chemical methods to control insect pests, diseases, weeds, and rodents—from field selection to harvesting.

Characteristic Features of Indian Integrated Pest Management Programme (IIPMP)

The Indian Integrated Pest Management Programme (IIPMP) has several key features:

• Popularizing IPM approaches among the farming community
• Monitoring and surveillance of pests and diseases regularly
• Studying agro-ecosystems to recommend timely pest control measures
• Developing, rearing, and conserving biological control agents
• Promoting bio-pesticides such as beneficial bacteria, insect pathogens, neem-based and garlic-based products as alternatives to chemical pesticides
• Transferring innovative IPM techniques and skills to farmers and extension workers across all states
• Human resource development through training programmes and establishment of Farmers’ Field Schools (FFSs)
• Field release of laboratory-reared bio-control agents
• Issuing insect-pest and disease situation bulletins for farmers and state authorities

Plant Quarantine and Crop Protection in India

In India, regulatory measures of plant quarantine are implemented under the Destructive Insects and Pests Act, 1914. The Plant Protection Quarantine (PPQ) system safeguards agriculture and natural resources by preventing the entry, establishment, and spread of plant pests, animal pests, and noxious weeds. It ensures a high-quality and secure food supply.

Conservation Tillage: Definition, Methods, and Importance

A method of soil cultivation that leaves crop residue from the previous year on the field before and after planting the next crop is known as conservation tillage.

Crop residues such as corn stalks and wheat stubble help reduce soil erosion, improve soil fertility, and minimize runoff. At least 30% of the soil surface remains covered with residue after planting to provide conservation benefits, while some methods retain up to 70% residue.

Types of Conservation Tillage Methods

• No-till farming – planting crops without tilling the soil
• Strip-till farming – tilling only narrow strips for planting
• Ridge-till farming – planting on permanent ridges (4–6 inches high)
• Mulch-till farming – retaining at least one-third soil cover with residue

These methods are especially suitable for erosion-prone agricultural land and require specialized equipment and management practices.

Environmental Benefits of Conservation Tillage

Conservation tillage offers several environmental and economic benefits:

• Reduces soil erosion by 60%–90%
• Protects soil from wind and rain using crop residue cover
• Improves soil structure and water infiltration
• Enhances soil and water quality through organic matter decomposition
• Conserves soil moisture by reducing evaporation
• Reduces fuel consumption and energy use due to fewer tractor operations
• Minimizes air pollution from dust and diesel emissions
• Provides habitat and food for wildlife
• Saves time, labour, and machinery costs
• Reduces soil compaction and improves crop growth
• Optimizes soil moisture during drought conditions

Trickle Drip Irrigation: Advantages and Role in Sustainable Farming

There are several types of irrigation systems, including flood irrigation, furrow irrigation, sprinkler irrigation, trickle drip irrigation, and sub-irrigation. Among these, trickle drip irrigation is highly effective for agricultural crops, while sprinkler irrigation is widely used in horticulture.

Advantages of Trickle Drip Irrigation

• High water-use efficiency
• Suitable for use with saline water
• Requires minimal land leveling
• Enables simultaneous application of water and fertilizers (fertigation)
• Produces higher yield with better crop quality and uniformity

Flood irrigation has been found to increase soil salinity and is being gradually replaced by drip irrigation systems and sprinkler irrigation in sustainable agriculture.

Factors Affecting Selection of Irrigation Systems

The choice of an irrigation system depends on:

• Land topography
• Soil type
• Rainfall pattern and availability
• Water resources and storage capacity
• Availability of power, labour, and finance
• Size of the irrigated area

Sprinkler irrigation is particularly suitable for irrigating pastures, golf courses, and grasslands.
