It has been spread over 60,000 hectares of orchards in recent three years, ensuring over 95 percent of insecticidal rate.

In this regard, Choe Tung Gwang, director of the center, told KCNA:

The nano-dispersant, the first of its kind in the country, is made with locally available raw materials 100 percent and its production method is quite different from world-known ones.

Researchers of the center settled technical problems arising in raising the insecticidal rate of the dispersant, including those of killing insect eggs and raising its infiltrative and transitional effect.
