Female scientist honoured for pest control research

HCM CITY — Nguyen Thi Loc is one of two Vietnamese female scientists who will receive the Kovalevskaia Award 2010 at a ceremony in Ha Noi on March 8, Tuoi Tre (Youth) newspaper has reported.

"I conduct research to help farmers cut harvest losses. The image of my mother working hard in the rice fields to take care of eight children is imprinted deep within my memory. I had to overcome difficulties to study and research," said Dr. Loc, head of the Cuu Long Delta Rice Research Institute's Insect Ecology and Biological Control Department.

Loc's products, including two entomogenous fungal bio-insecticides called OMetar and Biovip, have helped to control pests on rice and other crops.

Loc has also provided farmers with pest-management methods and cultivation tips on growing rice, crop, fruits and sugarcane.

"During the first few days, I saw farmers cleaning canal water with alum to use for their daily activities, and some even drank the water without boiling it while fertilisers and pesticides were just sprayed on rice fields nearby," she said.

Loc was shocked and decided to conduct research to create products that could replace toxic chemicals to protect rice crops and farmers' health.

"Maybe that was the reason I stayed in this region," she said.

In 1989, she studied in India for her post-graduate study. After taking her doctorate degree in entomophagous fungi, Loc received a US scholarship for post-doctoral study in biotechnology in plant protection. Loc then returned to the institute and worked with her colleagues conducting research and producing two bio-insecticides from Metarhizium anisopliae and Beauveria bassiana fungi to control brown planthoppers, rice bugs and lepidopterans.

In 2002, the Ministry of Agriculture and Rural Development approved the application of two bio-insecticides in agricultural production on a large scale.

The two bio-insecticides are listed in the country's plant protection medicine list with tradenames of OMetar and Biovip. Loc and her colleagues have transferred the techniques of producing OMetar to farmers so they can produce it themselves at a cost of about VND50,000 per ha each time they spray their fields.

This has helped farmers save billions of dong.

Farmers have also called Loc to visit their fields after they successfully applied the technique.

Loc said she would use the US$3,000 from the Kovalevskaia award to conduct research on the production of a bio-insecticide from microfungi to control pests on plants, especially on fruit trees.

The Kovalevskaia prize, named after a Russian female professor of mathematics during the 19th century, Sophia Kovalevskaia, was founded in 1985 to honour women scientists in developing countries. — VNS
