Nogall pest control
1989
pesticide using genetically altered bacterium

From the early 1900s, Australia has been a world leader in many areas of agricultural research. Biotechnology is opening up new industries in medicines and food production, and where there's industry there's innovation.

In the 1980s Australian scientists developed and patented a genetically engineered bacterium for use as a pesticide. Sold under the tradename Nogall, it was the world's first commercial release of a living, genetically engineered organism.

Crown gall disease attacks roses, raspberries, and nut and fruit trees. It is responsible for huge losses in crops around the world.

In the 1970s, scientist Allen Kerr discovered that a naturally occurring bacterium (called K84) produces an antibiotic against the crown gall bacterium. Unfortunately, K84 can transfer a copy of the gene for making the antibiotic to the crown gall bacterium, making it immune to the antibiotic.

Kerr had an idea for overcoming this problem. He used genetic engineering, snipping out the bit of K84?s DNA that allows it to transfer the antibiotic gene to the crown gall bacterium. The redesigned bacterium, sold as Nogall, effectively controls crown gall disease.

The research work performed by Allen Kerr won the first Australia Prize for Science in 1990. Nogall opened the way for agricultural techniques that give plants built-in resistance to pests and disease.
