The reporter learned from Shanghai Agriculture Commission was informed that the Broadcasting Corporation of China's WTO accession negotiations by the international attention the issue of China's export bonsai parasitic nematodes has been in Shanghai to find a prevention and control measures, a set of norms and quarantine treatment has been to Shanghai and other provinces of the customs departments.
Sinon Shanghai Science and Technology as a key project, "Shanghai Port bonsai plant-parasitic nematode species investigation and treatment technology research" issue by Shanghai Entry-Exit Quarantine Bureau of scientists assume. In three years, they are in Shanghai for nearly 30 kinds of main export bonsai extensive investigation and identification of nematodes found mainly in Shanghai under the nematode Bonsai 16 genera, 9 species identified important plant parasitic nematodes. Scientists initially mastered the seasonal dynamics of these nematodes to screen suitable for a soaking new type of insecticide treated seedlings. Experimental results show that the concentration of agents to deal effectively with no significant adverse effects on potted plants. At the same time propose comprehensive measures are effective at killing nematodes bonsai, and bonsai application of slow-release granules media to extend the treatment effect.
Ornamental plant parasitic nematodes that affect the growth of important pests. In recent years, as China's horticulture industry, bonsai nematode problems have become increasingly prominent. Bonsai often from abroad, China's exports a variety of parasitic nematodes intercepted. European Union, the United States, Canada and other countries have made on China's export bonsai tough phytosanitary requirements, a direct result of the sharp drop in export volume of China's bonsai. The China's accession to the WTO negotiations, this issue has also attracted national attention.
Scientists said that Shanghai right bonsai nematode research is "a breakthrough." Prior to academia in our country right bonsai plant protection there is no systematic study nematode species distribution, international studies have reported the problem to this one is also very small. Foreign trade department said, found a nematode control measures can be lifted by foreign countries against China's exports potted plant quarantine barriers to the export of China's resumption of bonsai "life."
