Quinclorac residues in tobacco and soil were determined using high performance liquid chromatography coupled to photodiode array detector (HPLC-PDAD). Quinclorac residues were extracted by 0.05 mol/L sodium hydroxide solution from tobacco and soil samples into acetyl acetate via liquid-liquid partition, and cleaned up with a SPE cartridge packed with active carbon and florisil. The average recoveries of quinclorac ranged from 79.4% to 94.9% in tobacco and from 92.9% to 108.2% in soil, respectively, at the spiked concentration levels of 0.05-2.00 mg/L. Relative standard deviation ranged from 8.1% to 12.9% in tobacco and from 5.5% to 9.6% in soil, respectively. It was proved that the method was easy, cheap, fast, sensitive, reproducible and practical. Source

Characteristics and problems of tobacco grower cooperatives in Hunan province and their development trend were analyzed and discussed. Construction pattern and operation mode were proposed in order to solve those problems. The objective was to promote overall construction quality of tobacco grower cooperatives. Cooperative construction would enter into a new stage when equal attention was paid to both quantity and quality. Multi-factor cooperation, construction of cooperatives association and comprehensive service cooperatives will become a new development trend. Source
