Research and Development of Citrus in Taiwan
The purpose of this investigation is to understand pesticides and heavy metals residue in citrus and orangery soil respectively. In past three years, from July 1991 to June 1994, we collected samples from main productive areas in Taiwan. We found that insecticide, fungicide and acaricide were used on citrus widely. And there was no tolerance for some of them, such as decamethrin, torak, quinolate, neoron, methyl parathion, triazid, tamaron, permethrin and cypermethrin. The heavy metals concentration ranges of orangery soil are as follows : arsenic was from 0.4ppm to 18.9lppm, cadmium was up to 0.47ppm, chromium was up to 3.22ppm, copper was from 0.67ppm to 109.5ppm, mereury was up to 0.43ppm, nickel was from 0.2ppm to 7.45ppm, lead was from 1.86ppm to 11.36ppm and zinc was from 1.54ppm to 58.63ppm. The pH value of 60 % orangery soil samples were less than 4.5 and only 19.77 % were between 5.5 and 6.5 which is proper pH range for citrus growth. There was no pesticide or arsenic be detected in orange juices.
