During a field survey, they found out a certain kind of perennial plant abundant in the country which can be used for making the botanical insecticide.

They established a method of making the insecticide by using the plant and pooled efforts with officials of various fields and local officials to examine and confirm the effectiveness of its application.

They successfully solved sci-tech problems arising in industrializing the production of the insecticide.

The production cost of the insecticide amounts to at least a third of that of chemical insecticides. And it effectively kills major forest vermin including caterpillar.

With the help of officials concerned, the scientists strive to expand the scope of its introduction.
