A scientist working with Eli Lilly and Co. made an interesting discovery while vacationing in the Caribbean in 1982.
The scientist visited a rum distillery and noted the absence of bugs in the soil around the still.
Soil samples were taken for testing and it was learned that bacteria in the soil were acting as a natural insecticide.
Eli Lilly and Co., a manufacturer of pharmaceuticals, knew that it had found something important.
The information was passed on the Elanco, which was then Eli Lilly’s crop protection division.Dow bought it in 1998.
Following more than 10 years of testing and development, a new product named Success was registered in the United States in 1997.The active ingredient was Spinosad, produced by fermenting the naturally occurring bacteria discovered by the Eli Lilly scientist.
Success is now registered in the U.S. by Dow AgroSciences for use in more than 170 different crops.
This year, Success 480 SC was registered for use in Canada to control oblique banded leafrollers in apples.
Dow AgroSciences spokesperson Stan Audette said the company wants to register Success for other Canadian crops, such as diamondback moth larvae in canola and the Colorado potato beetle.
Dow AgroSciences describes Success 480 SC as the first product in a new class of insect control known as naturalytes.
According to Dow AgroSciences, they are as safe for the environment and humans as biological products such as Bt. Bt is a soil-borne bacterium used to combat the European corn borer.
Larry Robinson, customer agronomist for Dow AgroSciences, said Success doesn’t harm beneficial insects such as ladybird beetles, lacewings, true bugs, spiders, and predatory mites.Those insects can help prevent the buildup of nuisance insects.
Sunlight helps Success break down in the soil within a couple of days, alleviating the potential for accumulation in the soil.
The company said Spinosad does not leach through the soil into ground water and does not persist in the environment.
In a news release, Dow AgroSciences noted that naturalytes are a effective or better than conventional insecticides.
Their unique mode of action makes them an ideal foundation for integrated pest management, Robinson said.
The lack of cross-resistance also makes the product legal for managing pesticide resistance, he said.In 1999, Dow AgroSciences was awarded the U.S. President’s Green Chemistry Award for developing the new class of chemistry. |
