The Conference was organized by AOAC International and funded by Agricultural and Processed Food Products Export Development Authority (APEDA), Ministry of Commerce, New Delhi under National Referral Laboratory Scheme. The paper entitled ‘Multi-residue screening of 100 pesticides in grapes by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry’ was presented in the session of ‘Analysis of Contaminants’ as a poster on 18th September 2006. The paper described the standardized method of sampling, extraction, cleanup and final estimation of 100 pesticides in grape matrix. The validation results including linearity range, limit of detection, limit of quantification, precision and accuracy results were reported for all analytes. Two-dimensional GCxGC separation of co-eluted pesticides was presented. The application of the above method in regular monitoring of pesticide residues in grapes under the residue monitoring program of the APEDA on the samples collected from the vineyards and pack-houses of India were demonstrated.
The objective of the programme was to study the effect of Advanced fertigation system in comparison to conventional fertigation on nutrient accumulation and leakage from the system in citrus garden. The experiment was laid out in Dareton in New South Wales (Australia). In this study tensiometers and ceramic cup soil water samplers at two different depths below the root zone were used to calculate deep drainage and nitrate leaching for an AF citrus trial site in the Sunraysia Region. The results showed that drainage was 18.5% and 23 kg NO3-N ha-1 was leached for the period between 30th of August 2007 to the 20th of June 2008. This equated to 16% of the nitrogen applied lost as NO3-N leaching. The results showed that the nitrate concentration in the 1.5 m SoluSAMPLER was regularly over the 10 mg/L NO3-N ha-1 threshold. This method of assessing deep drainage and nitrate leaching has been shown to be a viable option for assessing the environmental impacts of AF, due to nitrate leaching and will help in optimizing fertilizer use in citrus production.
