Under the non-poisonous food project, glyphosate was banned last year.
However, due to the demand for it, unscrupulous traders are importing it in powder form, missing it with other substances and selling in in Pettah without a label.
These traders are said to be making a profit of around Rs. 1.5 million per container of glyphosate by selling this to pesticide dealers they are familiar with.
While the standard glyphosate content is around 40%, this poisonous substance in the imported power form is around 80%.
According to information received, even reputed estate companies are said to be purchasing this illegally imported chemical and are using it in their estates.
Due to the shortage of labour and due to the ban on the use of glyphosate the productivity of the estates have reduced, said Minister of Plantation Industries Navin Dissanayake.
