Plant growth regulators to a more rational use of scientific knowledge to

CCTV 2 this evening of food safety press conference on the "terms of pesticide residue" by the Institute for Drug Control Po-kan, director of care as a pesticideexperts to answer the concerns of the media and consumers, in terms of agriculturalresidues to answer media questions and answers, the impression is too deep , Andbanana ethylene toxicity than table salt, is Forchlorfenuron toxic than table salt, andexcessive use is not much good, very clever answer.

    This year, the domestic consecutive on "banana ripening ethylene harm to human health" as well as untrue reports "led to the leavening agent watermelon explosion" and "hormone cucumber" over-exaggerated, so that the application of plant growth regulator is being questioned. Not only caused panic consumers, but also to the supply of agricultural products and farmers income as well as plant growth regulators industries, adversely affected. The participants believe that the phenomenon, has complicated reasons, the current mainly in the following four areas: 
    First, the lack of plant growth regulator application on the positive publicity, the public lack of plant growth regulators on the correct understanding, in case of false media reports, it is easy to panic in the community. 
    Second, in the practical application of plant growth regulators, the error still exists use, excessive use and inappropriate use of time to technical problems, the use of not only difficult to achieve the desired effect, but also give farmers a significant economic losses. 
    Third, some pesticide or plant growth regulator production enterprises, will be registered or not registered in the name of fertilizer products directly to the market.Some of these products not only of poor quality, but also in product identification and description is often used to expand the scope of exaggerated use of effects, easy to mislead the farmers, agricultural production hazards in the same time, the quality of agricultural products will also become a security risk. 
    Fourth is the business of plant growth regulators are mostly generic production of foreign products, and less self-created formulations behind the product, it is difficult to meet the needs of agricultural development.

Comparison of the recent media and consumer attention to the problem of plant growth regulator, the Information Office of the Ministry of Agriculture today announced the press conference, in order to enable the public to the scientific understanding.Chinese Academy of Agricultural Quality Standards and Testing Technology Research Institute researcher Ye Zhihua, said in response to a question, plant growth regulators to a less toxic products, in accordance with the "Pesticide Management Regulations" provisions are of pesticides plant growth regulator the scope of management, it is only through licensed pesticide registration and access to the production of plant growth regulator products in order to carry out production, management and use. 
    Reporter: The recent media reports prickly cucumber flowers top the plant growth regulator "pink" and what is the plant growth regulator? Plant growth regulator on the market How many? How to use? 
    A: The plant growth regulator for regulating plant growth and development of a class of substances. Plant growth regulator, also known as plant hormone, usually through artificial synthesis or microbial fermentation produced, their physiological role and biological effects and the natural plant hormone (a naturally occurring plants compounds) the same or similar. 
    Currently, the plant growth regulator widely used in the world agroforestry production, foreign varieties have been commercialized than 100, mainly ethylene, a piperazine onium, CCC, Thidiazuron, gibberellic acid, applied include vegetables, fruit, cotton, tobacco, rice, wheat, corn and soybeans and other crops. Registered for use of plant growth regulators in 38 varieties, commonly used are ethylene, gibberellic acid, nearly 10 varieties, mainly in horticulture, rice, cotton and other crops used.China has registered for use on cucumber varieties Thidiazuron, Forchlorfenuron, nucleotides, brassinolide, sodium nitrophenolate, NAA, IBA and other seven species, the main role is to promote the growth of female flower to improve fruit set and so on. 
    Plant growth regulator as a less toxic products, if approved in accordance with national registration to use on the label and precautions to use, is safe. The use of plant growth regulator, not only to protect crop yield, improve the quality of agricultural products, but also can enhance the resistance of crops, so saving time and labor of agricultural production, efficiency of the section. 
    Reporter: the state's use of plant growth regulators What are the requirements? 
    A: According to the "Pesticide Management Regulations" provisions, plant growth regulators are the scope of pesticide management, pesticide registration and access is only through licensed production of plant growth regulator products in order to carry out production, management and use. 
    Our very strict requirements on pesticide registration, application for registration of pesticide products need to be a lot of testing, from product chemistry, efficacy, toxicology, residues, environmental impact and other aspects of critical review and scientific evaluation, and only after scientific evaluation, proven good control effect, while human and animal health and environmental effects of controlled, consistent with protection of human health and environmental safety requirements, in order to obtain registration. Production and management of pesticides, to be approved by the relevant department with the label, clear and effective ingredients, and precautions such as use of the content. Plant growth regulator used in strict accordance with the use of labeled doses, the use of time and use of standard use, not abuse. 
    Reporter: What is a plant hormone? Ripening of the fruit with the hormone will not harmful? 
    A: The plant hormone is naturally occurring in plants on plant growth, a significant role in development of trace organic substances, also known as plant hormones or plant natural endogenous hormones. Its existence and effective regulation can affect plant growth and development, including cell growth, division, to take root, sprout, blossom, mature and fall off the whole process a series of plant life. 
    Plant Growth Regulator is a natural plant hormone in understanding the structure and mechanism of action, the hormone through artificial synthesis and with similar physical and biological effects of substances used in agricultural production, effective crop fertility regulation process, to yield stable to improve quality, enhance crop resistance and other purposes. 
    Registration of approval on the label by the use of dose, time and method of use of plant growth regulator will not cause harm to human health. If you are using does not appear on the standard, may cause excessive growth of crops, quality and taste of farm products will have some impact, but will not cause harm to human health. 
    Reporter: The existing means of agricultural product quality safety supervision and can detect whether a plant hormone? 
    A: The plant hormone into endogenous hormones and exogenous hormones. Only exogenous hormones (plant growth regulator) has detected problems. Approved for use by the state of plant growth regulator, has a corresponding detection methods.Agricultural products quality and safety of existing regulatory and professional testing organizations, all agricultural products with detection ability of plant growth regulator, can accurately detect whether a plant growth regulator, needs to be noted that, due to major in plant growth regulator supporting the use of plant growth process, the general public in a mature fruit or low residue products, sophisticated analytical instruments required for accurate quantification. (Source: Legal Daily)
