India: Bayer CropScience reduces pesticides in grapes
The experiment involves the development of a set of good practices by Bayer and the National Research Centre for Grapes.
The project has so far shown a reduction in the usage of sprays, as well as offering cost savings, yield increases and the potential for further exports.
Previously growers in the area have had to use sprays to control downy mildew.
Bayer's approach, according to Joerg Rehbein of the company, involves paying close attention to the weather through satellite information and a weather station. Spraying is then carried out according to need, as opposed to the full scale treatment that is currently being applied regardless of meteorological conditions.
“The package involves, among other things, spraying before the rain starts and not during the time it rains,” he said.
Reduction in the number of sprays based on weather information not only resulted in cost saving, but also reduced fungal attack and substantially lower maximum residue limit.
Such practices are required to ensure acceptance of the produce in international markets, some of which are very conscious of pesticide levels.
