Analytical method for nitrapyrin and 6-chloropicolinic acid residues in strawberry fruit and soil

Nitrapyrine (2-chloro-6-(trichloromethyl)pyridine), a highly specific nitrification inhibitor, is the active ingredient of N-Serve. Used as a preplant soil application at a rate of 0.5 lb of AI/acre, strawberry yields were increased by similar to 2.5 tons/acre. Residue analytical methodology for nit...

Description
Summary:Nitrapyrine (2-chloro-6-(trichloromethyl)pyridine), a highly specific nitrification inhibitor, is the active ingredient of N-Serve. Used as a preplant soil application at a rate of 0.5 lb of AI/acre, strawberry yields were increased by similar to 2.5 tons/acre. Residue analytical methodology for nitrapyrin and its principal degradation product 6-chloropicolinic acid in strawberry fruit and soil is presented. No determinable residues of nitrapyrin ( greater than or approximate to 0.04 ppm) were detected in field-grown strawberries. The maximum level of 6-chloropicolinic acid found was 0.09 strawberries. Residue data for soil are also presented.
