10种常用植物生长调节剂在我国的登记情况

Registration Status of 10 Kinds of Common Plant Growth Regulators in China

为了解我国植物生长调节剂登记情况,选择赤霉酸、多效唑、萘乙酸、氯吡脲、芸苔素内酯、乙烯利、噻苯隆、苄氨基嘌呤、复硝酚钠、单氰胺等10种田间常用植物生长调节剂作为调查对象,在中国农药信息网进行检索,采用计量学方法从登记企业分布、登记作物、登记原药及制剂、登记剂型等方面进行统计分析。结果表明:10种植物生长调节剂生产厂家主要分布在华东区、西南区、华中区,3个地区共登记产品320个,占73.73%。其中江苏省、四川省和河南省登记数量居前3位。登记作物中,水果、农作物、蔬菜、其他作物分别以葡萄、棉花、番茄、烟草和橡胶树为主。登记原药和制剂方面,除苄氨基嘌呤以复配剂为主外,均以单剂为主。登记剂型共21种,以水剂、可溶粉剂、乳油、可湿性粉剂、可溶液剂为主,其余16种剂型登记数量均在6%以下。就单个药剂登记剂型而言,复硝酸钠、单氰胺、乙烯利、萘乙酸和芸苔素内酯以水剂为主,氯吡脲和苄氨基嘌呤以可溶液剂为主,多效唑以可溶粉剂为主,噻苯隆以可湿性粉剂为主,赤霉酸以乳油为主。

In order to understand the registration status of plant growth regulators in China,we selected 10 kinds of commonly used plant growth regulators,gibberellic acid（ GA）,paclobutrazol（ PP333）,1-naphthaleneacetic acid（ NAA）,forchlorfenuron（ CPPU）,brassinolide（ BR）,ethrel（ ETH）,thidiazuron,6-benzylamino-purine（ 6-BA）,compound sodium nitrophenolate,cyanamide,as the investigation object,and based on the retrieval of China pesticide information network（ ICAMA）,used the metrology to analyze the registration manufacturers distribution,crop,raw pesticide,preparation,formulation and other aspects. The result revealed that the manufacturers of the plant growth regulators were mainly distributed in East China,Southwest China,Central China. Three regions registered a total of 320 products,accounting for 73. 73%.Jiangsu,Sichuan and Henan ranked top three in registration number. In all registered crops,fruits,crops,vegetables and other crops were mainly grape,cotton,tomato,tobacco and rubber tree,respectively. In the aspects of raw pesticide and preparation,except 6-BA with mixtures as the main type,other pesticides were dominated by single chemical pesticide. 10 kinds of plant growth regulators were registered as a total of 21 kinds of formulations,mainly in liquid,soluble powders,emulsifiable concentrate,wettable powders,and soluble concentrate,while the registered number of the other 16 kinds of formulations was all below6%. As far as the single plant growth regulator concerned,compound sodium nitrophenolate,cyanamide,ETH,NAA and BR were mainly registered as liquid,CPPU and 6-BA were mainly soluble concentrate,PP333,thidiazuron,and GA were mainly soluble powders,wettable powders,and emulsifiable concentrate,respectively.
