Colorado potato beetles are a dreaded pest of potatoes all over the world. Now, scientists from the Max Planck Institutes of Molecular Plant Physiology in Potsdam-Golm and Chemical Ecology in Jena have shown that potato plants can be protected from herbivory using RNA interference (RNAi).

Of the more than 100 diseases of potato, bacterial ring rot is one of the few zero-tolerance pests. If just one seed potato on a farm is found to have this disease, no seed on that farm can be certified.

In the Indian State of Karnataka, the Department of Horticulture has decided to provide certified seed potatoes to 1,000 farmers for pre-monsoon cultivation on a pilot basis.
