A research group of the institute adopted a new method of analyzing the percentage of nicotine in an oily medicine to produce the insecticide by combustion.

It has been proved through application that the insecticide is efficacious against over 10 species of harmful insects and its rate of exterminating harmful insects from roadside trees reached over 95 percent.

It is low in production cost and its production process needs less power consumption.

Now, the Ministry of Agriculture is pushing ahead with a project to set up its production bases in different parts of the country.
