No sight of pests after applying light spectrum technology

In Chi Lang Nam commune (Thanh Mien, Hai Duong), the Center for Science and Technology Application and Seed Testing (Hai Duong Department of Science and Technology) recently held a workshop to evaluate the results of "Transfer the application of light spectrum advanced technology to the production of flowers and fruit trees in Hai Duong province".

In 2023, the Center for Science and Technology Application and Seed Testing implemented a melon growing model in membrane houses and nethouses using insect-catching lights Model DCT.01 DA 8W at Bui Van Duy's household in Kim Xuyen commune (Kim Thanh district) and Vu Van Phong in Chi Lang Nam commune (Thanh Mien district) with a total area of 2,000 m².

As a result, the household stopped using pesticides and switched to pest-catching lamps, and there was no sight of pests in the gardens. The method is applied creatively as farmers do not leave the lights fixed at one point but instead move them continuously to many different locations in the garden on a cycle of 5-7 days. When turned on, the lamp uses the UVA light spectrum to attract gray butterflies, brown planthoppers, thrips, gnats, beetles and destroy them with high-voltage electric shock by a metal grid. The lamp has low power consumption, safe, effective, and easy to operate.

In terms of economic efficiency, after deducting the cost of electricity, farmers save nearly VND 1.5 million/year/1,000 m² of crops compared to using pesticides. This technology brings many social benefits as well. Not using pesticides will lessen the effects on the environment, and the final products are clean and safe to consume, contributing to protecting the health of both producers and consumers.
