The Forestry Department is using a <u>chemical</u> control method. This involves using a <u>foliar spray </u>method, in which department personnel will spray pesticide directly on the trees’ leaves.

The chemical control method of pesticide control involves spraying chemical pesticides directly on leaves, shoots or roots of the plants. These chemicals are toxic to the pests only and the pests get retracted from the plants because of the pesticides applied.
A selective pesticide application is done to limit application to a target harmful pest which kills only that and does not harm the other useful or harmless species which thrives on the plants.
