In modern rice production, pests and diseases are always one of the main causes of reduced yield and quality. Previously, many farmers relied heavily on pesticides to control pests. However, the overuse of chemical pesticides not only increases production costs but also negatively impacts the environment, human health, and increases the risk of developing pesticide-resistant pest populations. Therefore, Integrated Pest Management (IPM) is considered an effective and sustainable solution in rice cultivation.

IPM is a pest management method based on combining various measures to control pests and diseases at an economically acceptable level, rather than completely eradicating them. The core principle of IPM is to prioritize biological, cultural, and mechanical methods before using chemical pesticides. This approach helps maintain ecological balance in the field, protects beneficial natural enemies, and minimizes negative impacts on the environment.

One of the key elements of Integrated Pest Management (IPM) is the use of rice varieties with good pest and disease resistance. Selecting varieties suitable for local conditions helps reduce the risk of outbreaks of common diseases such as blast, bacterial leaf blight, brown spot, and brown planthopper. In addition, farmers need to apply rational farming practices such as sowing at the right time, at the right density, balanced fertilization, and effective water management to create conditions for healthy rice plant growth.

Regular field monitoring is an indispensable requirement of the IPM program. Periodic inspections help detect the early appearance of pests and diseases and assess the level of damage before implementing treatment measures. Instead of spraying according to a fixed schedule, producers should base their intervention timing on the control threshold. This helps avoid unnecessary spraying, saves costs, and limits chemical residue in agricultural products.

Natural enemies such as predatory spiders, ladybugs, parasitic wasps, and dragonflies play a crucial role in the natural control of many pests on rice plants. Conserving and developing these natural enemy populations through reduced use of broad-spectrum chemical pesticides contributes to maintaining a stable field ecosystem. Many studies show that fields applying IPM (Integrated Pest Management) tend to have higher densities of natural enemies and fewer severe pest outbreaks.

When pesticides are needed, IPM recommends selecting highly selective pesticides that have minimal impact on beneficial organisms and adhering to the "four correct principles": correct pesticide, correct dosage, correct timing, and correct application method. Farmers need to carefully read instructions, wear appropriate personal protective equipment, and observe the required waiting periods to ensure safety for consumers and the production environment.

The application of integrated pest management has brought many practical benefits to rice growers. Many practical models show that pesticide use can be reduced by 20–50%, while rice yield and quality are maintained or improved. Simultaneously, production costs decrease, profits increase, and the field environment becomes more balanced.

In the context of agriculture moving towards green and sustainable development, Integrated Pest Management (IPM) is not just a technical measure but also an effective production management strategy. Raising awareness, training farmers, and expanding IPM models will contribute to building a safe, environmentally friendly rice production system that better meets the requirements of both domestic and export markets.
