Definition, basic principles of integrated pest management
1.1. What is Integrated Pest Management (IPM)?
According to the expert group of the Food and Agriculture Organization (FAO), "Integrated Pest Management" is a pest management system that in the specific the context of the environment and the population dynamics of the species causing damage, using all the techniques and appropriate measures can be, in order to maintain the density of the pest below cause economic damage.
Abbreviation
Thus, IPM stands for Intergrated Pest Management
1.2. Five basic principles of integrated pest management (IPM)
(i). Planting and health care of crops:
-
Choose good seed, suitable for local conditions.
-
Choose healthy and qualified crops.
-
Planting, cared for properly techniques to grow good crops which are resistant and high yielding.
(ii) Check fields regularly, understand the progress of the growth and development of plants, pests, weather, land, water ... to take timely remedial measures.
(iii) Farmers become experts field: Farmers' technical knowledge, management skills need to advocacy field for many other farmers.
(iv) Pest prevention
-
Using appropriate preventive measures, depending on the severity of disease, parasitic natural enemies in each stage.
-
Using of chemical drugs has reasonable and proper technique.
(v) Protect natural enemies: Protecting the beneficial organisms to help farmers kill pests.

2.1. Farming methods
(i) Early land preparation and field sanitation
-
Land preparation and field sanitation soon after planting to kill many caterpillars and pupae live in the rice stem borer and rice stubble, loss of shelter and food source of the brown planthopper, green hoppers... Brokers are the transmission of viral diseases for rice as dangerous illness blighted gold, rice ragged stunt disease.
-
Principles of impact of field sanitation measures and handling crop residues after harvest is cut off the ring cycle of pests from the crop to other crops and pests limited source accumulation, transmission spread at beginning of the crop.
(ii) Crop rotation
Rice rotation with other crops to avoid pathogen accumulation in rice from the crop to other crop.
(iii) Appropriate Planting
Planting rice to ensure appropriate growth and good development, achieve high productivity, avoids the risk of the weather. The determination of appropriate the crop having to rely on the characteristics of the damage incurred pests important to ensure that rice avoiding peak of the epidemic.
(iv) Use healthy seeds, pest resistant and short seeds
-
Healthy seeds, free disease helps to rice facilitate development
-
Using resistant rice seeds reduce drug use chemical pest control, reduce pollution, protect natural enemies; keep balance agricultural ecosystems.
-
Rice seed with short growth period of about 100-110 days, plant earlier in the season could have been avoided borer, deep bite panicle. Rice seed with extremely short growing period is 80-90 days brown planthopper prevention measures effective for brown plant hopper could not accumulate in sufficient quantities to cause severe damage in extremely short day breeds.
(v) Cultivation density is reasonable
-
The density and sowing techniques, depending on the rice seeds transplanting, crop, soil and nutrition, aged rice, rice quality, process agricultural intensification...
-
The density is too thick or too little will affect productivity, while also affecting the generation and development of pests, weeds.
-
The rice fields are often sown too thick closed up early, causing high humidity, creating conditions for sheath blight and brown plant hopper damage incurred at the end of the crop.
(vi) Using reasonable fertilizers
Fertilization excessive or unreasonable fertilizer will make plants grow normally and not prone to pest infestation. Rice fields fertilization are more susceptible to infectious diseases rice blast, sheath blight, leaf blight...
2.2. Manual methods
Light traps catch butterflies, break eggs, rub stripping foil fencing using leaf spray, dig down to catch mice …
2.3. Biological methods
(i) Creating a favorable environment for beneficial organisms are natural enemies of pest development to contribute to kill pests:
-
Protection of natural enemies to avoid toxic chemicals by using selective medication drugs, narrow-spectrum drugs, drugs used when absolutely necessary and should be based on economic thresholds...
-
Create habitat for natural enemies after planting by intercropping, planting legumes on bunds, disintegrator for lurking natural enemies...
-
Application of cultivation techniques facilitate reasonable development natural enemies.
(ii) Priority use drugs Biological Plant Protection;
The medicines is effective only biological pest control, non-toxic to beneficial organisms, safe to human health and the environment
