Expert: Use in accordance with the rule " Expand pharmaceutical " Harmless health
" expand " Water-melon, " Accelerate the ripening " Banana, " Contraceptive " Cucumber Lian Ri comes, use and grow the fruit of modulator, edible security of vegetables to attract people's extensive concern. The expert says, plant growth regulator is safe according to allowing the range and allowing the consumption to use, will not cause the health to endanger.
Must pass safety evaluation before being listed
"Judge whether a chemical material is poisonous, whether adversely affect health, must link with dosage! " In the afternoon of May 20, in a laboratory on the 2nd floor of department of agriculture of China Agricultural University, famous plant growth regulator of our country employs the expert He Zhong to wear the professor to say clearly.
Say ZhongPei He,our country already including being " expand by dose " Plant growth regulator inclusive includes in the range of management of pesticide. According to the provision of " pesticide management rule ", the pesticide products that have only obtained agriculture chemical registration and handled production permit, could produce, manage and use. Apply for the pesticide products of registration, is only commented on by science, prove better prevention and cure result, there are controlled in environmental impact on health for people and animals sum,can Acquisition Registration.
Zhong He wear introduction, security of plant growth regulator mainly through little white the intersection of mouse and the intersection of acute poisoning and dosage(half cause death dosage) Come, appraise, according to the intersection of Chinese and the intersection of pesticide and the intersection of toxicity and hierarchical standard, " expand pharmaceutical " Principal ingredients chlorine pyrrole urea are low-toxicity, preparation is a little poisonous. Another kind is likewise low-toxicity growth modulator ethylene profit ' Ripener) ,Original the intersection of medicine and little white the intersection of mouse and the intersection of acute poisoning and dosage, for each the intersection of weight and 5110, equal to sodium chloride toxicity its.
Taking the operation instructions of pyrrole urea of a copy of chlorine in hand, He ZhongPei says, when our country is sanctioning agriculture chemical registration, have stipulated the period of using medicine, spent medicine quantity and used the method at the label, have marked scope of application and security interval. "In practical application, what the melon grower should stipulate according to the label strictly spends medicine quantity, period of using medicine and uses the method and construct medicines, if improperly use, either improve the dosage or handle the irregularity, will lead to the fact some density is too high without authorization, medicines such as odd-shaped fruit, dehiscent fruit,etc. appear to suffer from symptom. "
Will not cause " The sexual precosity "
Talk about the side effect of hormone, the first response of people's is often " little baby's long moustache " , " sexual precosity " . Then, use the intersection of plant and melon and fruit of hormone will let the intersection of eater and " the sexual precosity " too ? As to this, He ZhongPei shows clearly, hormone of plant leaves different from function mechanism of animal's hormone, it is " totally different thoroughly " .
He ZhongPei says, plant growth regulator delays growing and promoting two pieces of function of growth. The banana that the media of Israel reports recently " Ripener " The profit of ethylene is the example, achieve the goal of promoting bananas to grow through releasing ethylene. As a kind of plant hormone ' Grow plainly) ,Ethylene natural exists in the body of banana too. The experiment shows, growth and save that the too high ethylene profit passing the low density is unfavorable to the banana, "it is not good to use result instead more. " So-called what the cucumber is used " Contraceptive " Also belong to this kind. Vegetable grower use, start from purpose that cucumber keep fresh usually, too can accelerate cucumber grow, elongate the intersection of melon and body.
"Needn't hear hormone is tense, the growth like profit of ethylene is plain to only work with growth speed of the plant, do not matter with animal's hormone. In addition, the toxicity to the animal of the profit of ethylene is very small, security is high, the unnecessary big hat that fears hormone. " He ZhongPei says with a smile.
Should strengthen supervision to guide and use correctly
He ZhongPei thinks, though it is safe to produce plant growth regulator used according to the regulation, but must notice, really there are some bad producers through registering, not producing, selling according to the standard at present.
"As the material with synthetic chemistry, if the raw materials used are inferior, there is some unknown impurity, on one hand, may be used by peasants and come to naught, or destroy plants and grow, agriculture of the hole, hurting agriculturally; On the other hand, may also bring the hidden danger to eating the security of the future. " He Zhong wears proposing, the relevant department replies this and devotes more efforts to supervising. Meanwhile, because the scale intensity of agricultural production of our country is not high, how to lead the scattered peasant family to use, grow modulator correctly is a problem to be solved urgently of government department.
Ministry of Agriculture: 60 " expand pharmaceutical " Products Acquisition Registration
To having something to do with in the society " Expand pharmaceutical " Some query,last interview Ministry of Agriculture website solve to doubt whether to answer is puzzled.
Q: In the fruit " Expand pharmaceutical " Does the remaining amount have national standards?
A: Food and Agriculture Organization of the United Nations (FAO) , World Health Organization (WHO) Having set up pesticide safety evaluation norm and criterion, developed countries such as America and Europe,etc. have set up a set of strict risk appraisal systems. Our country is according to the international criterion, on the basis of using the experience of developed country for reference, set up comparatively complete pesticide safety evaluation system. U.S.A., Japan will be when a lot of developed countries " Expand pharmaceutical " Classify as, need, carry on toxic exemption material list of management, it remains and does not need to make the safe standard with a limit on quantity, a scientific evidence does not indicate to be harmful to health at present.
Q: Use " expand pharmaceutical " The picture " The clenobuterol hydrochloride " Belong to adding illegally equally?
A: According to the definition of pesticide of " pesticide management rule " that the State Council issued of 1997, " expand pharmaceutical " It is a pesticide category. The intersection of chlorine and the intersection of pyrrole and urea, red and mould and sour" Expand pharmaceutical " With " clenobuterol hydrochloride " Have essential difference, chlorine the intersection of pyrrole and urea, red mould acid belong to, register, sanction, allow the intersection of pesticide and variety that use, and " clenobuterol hydrochloride " Belong to the illegal garniture that the country prohibited production, sale and use by official order.
Q: It is reported " Expand pharmaceutical " Is developed by Japan, but the deformity of the melon and fruit appeared later, no longer use, why was our country still using?
A: Pyrrole urea of chlorine was researched and developed in U.S.A. at first initially, Japan began to produce and use in 1985. According to investigating and verifying, at present, pyrrole urea of chlorine is still registered and used in Japan, it is crops (it is not like what some experts said such as grape, kiwi fruit, water-melon, muskmelon, eggplant, tobacco,etc. to register the range, Japan has already stopped registering and using) . Will it be will it be the end the eighties the 20th century, our country introduce from Japan this kind " expand pharmaceutical " ,Won agriculture chemical registration of our country in 1992, and began in some provinces application. At present, pyrrole urea of chlorine not only uses relatively widely in our country but also using in U.S.A., European Union, Australia, Japan, South Korea etc extensively.
Red mould acid, as plant growth regulator, first by Britain until 1961 develop, produce. In 1985, the manufacturing enterprise of domestic pesticide won agriculture chemical registration of our country. At present, red mould acid uses extensively worldwide, has not found yet that harmful to human body.
Q: " expand pharmaceutical " How is the production status in our country?
A: At present, have 60 " expand pharmaceutical " Products, in our country's Acquisition Registration, there are 2 kinds (chlorine pyrrole urea and red mould acid) of effective compositions contained ,Involve the manufacturing enterprise of 45 of pesticide, these enterprises are national pesticide specially-designated factories, possess corresponding working condition and ability, the products sanctioning being registered in production are legal.
