At 9:30 on the morning of March 21, the vegetable wholesale market in Futian Town, Boluo County was bustling, and vegetable trading continued
.
In the contiguous vegetable field next to the market, many vegetable farmers are rushing to spray the medicine at the best time of the day
.
Xie Chengchao, a rented farmer from Guangxi, is spraying pesticides.
There is a 100ml bottle of pesticides without labels in a plastic bucket next to the vegetable field
.
"The owner of the retail store didn't tell what the ingredients were inside.
Anyway, the insects would die as soon as they sprayed.
They said they could be harvested within three or four days after spraying
.
" Four days later, the "Vegetable Safety and Pesticide Industry Standards" sponsored by the Southern Rural News At the seminar, vegetable farmers have been criticized for the fact that there is no "safe interval" concept and "three nos" (no manufacturer, no nominal active ingredient, no control object) pesticides rampant in the vegetable area
.
? Keep the interval between vegetables safe? "Producers must be self-disciplined.
After using pesticides, even high-efficiency and low-toxic pesticides, there must be a certain safe interval before harvesting.
Don't think that you can sell it if you eat it
.
" Guangdong Province Member of the Chinese People's Political Consultative Conference and professor of the College of Horticulture of South China Agricultural University Chen Riyuan advised vegetable farmers
.
? The so-called safe interval refers to the time required for the pesticide residue to fall to the pesticide residue tolerance specified in the food before the last application of the crop to the harvest
.
Because of the different characteristics and degradation speed of various pesticides, and the different growth trends and seasons of various crops, the safety interval after pesticide application is also different
.
Fan Shudeng, general manager of Guangzhou Tongzhi Crop Science Co.
, Ltd.
, introduced that the safety interval of most pesticides used in the production process is 7-14 days, specific to different types of pesticides: general biological pesticides are 3-5 days, pyrethroids 5-7 days for pesticides, 7-14 days for organophosphorus pesticides
.
? "As long as pesticides are used, there are residues.
If pesticides are not used in accordance with national safety regulations and agricultural products are harvested, or if the use of banned and highly toxic pesticides in violation of national regulations, the pesticide residues will exceed the standard
.
" Vice President of Guangzhou Academy of Agricultural Sciences , Researcher Zhang Hua said that this will cause harm to the health of consumers, and in severe cases will cause physical discomfort, vomiting, diarrhea and even death
.
In this regard, various countries have strictly controlled the application of pesticides and have stipulated the tolerance of pesticide residues in food.
The safety interval of pesticides is determined based on the tolerance of pesticide residues
.
? "In specific operations, in order to ensure the safety of vegetables, the time between the last spray and the harvest must be greater than the safety interval
.
" Zhang Hua said that only if the pesticide residue content is guaranteed to be within the allowable range specified by the state, can its safety be It's not a problem, it's safe vegetables that can be eaten
.
? Tracking vegetables from the field to the table should have undergone several pesticide residue inspection checkpoints at the origin wholesale market, terminal wholesale market, farmer's market or supermarket, but because the production is mainly distributed, the circulation link is large and complex, and the agricultural Vulnerabilities in pesticide detection procedures and technology, relying on detection to prevent vegetables with pesticide residues exceeding the standard become a fantasy
.
Therefore, it is hoped that vegetable farmers will keep the pesticide safety interval as the last line of defense to ensure vegetable safety
