Getting plants to rid themselves of pesticide residues
Scientists in China have discovered that a natural plant hormone, applied to crops, can help plants eliminate residues of certain pesticides. The study is in the current issue of ACS’ Journal of Agricultural and Food Chemistry, a bi-weekly publication.
Jing Quan Yu and colleagues note that pesticides
are essential for sustaining food production for the world’s growing
population. Farmers worldwide use about 2.5 million tons of pesticides each
year. Scientists have been seeking new ways of minimizing pesticide residues
that remain in food crops after harvest — with little success. Previous
research suggested that plant hormones called brassinosteroids (BRs) might be
an answer to the problem.
