the weather in Xinchang, Zhejiang, has just been a bit hot. The Chinese tea market in the western part of the county has not been bustling about a month ago - the harvest of spring tea has come to an end.
a half month ago, a warm discussion caused by the report of international NGO Green Peace related tea pesticide residues seemed to have no effect on the trade in the tea market. A peddler peddled her tea to tourists: "yesterday, it was very fresh."
in April 28th, the Ministry of health and the Ministry of agriculture jointly held a media ventilation meeting to explain the problem of pesticide residues in green peace report.
in two reports published in green peace in April 11th and April 23rd, the tea products, including 10 enterprises including Lipton, Tianfu tea, Wu Yutai and Zhang Yiyuan, detected the pesticides banned by the Ministry of agriculture.
Dong Hongyan, director of the standard office of the agricultural quality and Safety Supervision Bureau of the Ministry of agriculture, told the present media that the reason why endosulfan, Do-win and other pesticides were used in the tea tree upper limit were detected in the brand tea, mainly due to the residual in water and soil and the drift caused by the use of other crops. .
the actual situation seems not so, this reporter in Shengzhou, Xinchang, Zhejiang and other places of investigation found that endosulfan, Do-win and other pesticides are still not fortified to tea farmers.
as the main producing area of Longjing tea, Xinchang is also the source of Tianfu tea, Wu Yutai and eight horse brand manufacturers, of which Tianfu tea tea is first entered in Xinchang. And a reporter found that Tianfu tea in Xinchang tea purchase is mainly by dealers agent purchase, if problems, can be traced back to the source still doubtful.
the situation of illegal use of pesticides by some tea farmers in Xinchang, Zhejiang is typical. As the hometown of China's famous tea, there are only 400 thousand people in this county, and 180 thousand people are engaged in the tea industry. In 2011, the output value of Xinchang tea industry chain reached 1 billion 500 million yuan. The per capita income of farmers is 1/3 from the tea industry. Tianfu and other large tea brands have acquired tea from Xinchang and other places.
"a lot of tea farmers do not drink summer and autumn tea"
"according to the banned and restricted pesticide catalogue published by the Ministry of agriculture, there are 24 kinds of pesticides now banned, including 21 kinds of pesticides, including endosulfan, Do-win and three chloroacarol, to revoke their records on tea trees and limit their use on tea trees.
the agricultural store in Xiyan town is the main place to buy pesticides, where the reporter saw endosulfan. "Endosulfan can be used on the tea tree." The head of the agricultural store said.
in the two villages and towns of Hui mountain in Xinchang County, the reporter has also got the affirmative answer to the use of endosulfan and Do-win in tea tree. "Endosulfan should be used once a month." The head of a farm in Hui Shan town said.
at present, most of the tea growing areas are low toxic and low residue pesticides, but the banned pesticides such as endosulfan are not without market.
"toxic pesticide has good insecticidal effect, long effective time, once a month." A tea grower in Xinchang County told reporters that "those toxic pesticides are too slow and effective."
spring tea is better. "I only have spring tea every year, and there is almost no pesticide in spring tea." A tea farmer in Xiyan town of Shengzhou told reporters that after the spring tea harvest, she would prune the tea tree and wait for it to be harvested before the next year. "There will be three pesticides in the middle of 5, 7 and October, so that the tea trees will not die because of pests, and when they are picking spring tea, they will surely be gone."
not all tea farmers will grow tea in such a way. "Next door village will pick summer and autumn tea, starting from May will be spraying pesticide, once a week to half a month." The tea farmer said, "if we pick summer and autumn tea, the income per mu will be doubled."
"because of the increase of temperature in summer and autumn, the occurrence probability of diseases and insect pests is increasing. It is inevitable to prevent and control the use of pesticides." Liu Xinshuo, executive deputy director of the tea quality supervision and testing center of the Ministry of agriculture, "the key is to control pesticides well."
an important factor in controlling pesticide residues is the control of pesticide safety interval. When reporters visited the tea garden in Shengzhou and Xinchang, many tea growers did not distinguish between the safe isolation period of pesticides. They were generally considered to be 7 days.
but in fact, the safety intervals of different pesticides are not the same. For example, the standard interval of safe interval for tea growers such as thiazide is 10 days.
the above tea growers told reporters that if they were to pick summer and autumn tea, they would spray when they found worms. "Young buds come out for a month, if the middle of the insect, or to spray, but as long as the bud out, whether or not to the isolation period, or someone will go."
"many tea farmers do not drink summer and autumn tea," he said. "There is no pesticide in spring tea, and summer and autumn tea is hard to say."
