HG/T 2743.3-1996 Specification for the preparation of pesticide compound powder product standards
Some standard content:
HG/T2743.3—1996
The compound preparations scientifically mixed with different pesticides can greatly improve the efficacy, reduce toxicity and delay the emergence of resistance. Therefore, the development and application of compound preparations of pesticides are important ways to use pesticides rationally and effectively prevent and eliminate diseases, insects and weeds. At present, there are hundreds of compound preparations of pesticides in my country, but many varieties lack scientific experimental basis. The preparation of compound preparation standards is mostly chaotic and of varying levels. In order to standardize the preparation format of pesticide compound preparations and improve the standard level, this standard is formulated on the basis of GB/T1.1-1993 "Guidelines for Standardization Work Unit 1: Drafting and Expression Rules of Standards Part 1: Basic Provisions for Standard Preparation" and the industry standard ZBG23001--86 "Principles and Procedures for Naming Common Names of Pesticides" of the Ministry of Chemical Industry, and on the basis of HG/T2467 "Format for Preparation of Pesticide Product Standards". Appendix A of this standard is the appendix of the standard.
This standard is proposed by the Technical Supervision Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of Shenyang Chemical Research Institute of the Ministry of Chemical Industry. This standard was drafted by Shenyang Chemical Research Institute of the Ministry of Chemical Industry. The main drafters of this standard are: Hou Yukai, Wang Xuecheng, Lou Shaowei, Yang Jian, Zhao Xinxin.

Appendix A
(Appendix to the standard)
Principles for naming common names of pesticide compound preparations According to the basic principle of ZBG23001-86 "Principles and Procedures for Naming Common Names of Pesticides" Article 1.2 "The common name of pesticide preparations (single or mixed) should include three parts, namely, the mass percentage of the active ingredient, the common name of the active ingredient and the dosage form. The common name of the mixed preparation can be composed of the prefixes or pronouns of the common names of the active ingredients". The naming of the compound preparation is divided into three parts: the first is the total content of each active ingredient in the compound preparation (mass percentage or g/L (20℃)); the second is the common name of the compound preparation, which is composed of the prefixes (or the first few characters) of the common names of each active ingredient. A dot is inserted between the prefixes (or the first few characters) to reflect the compound preparation; the order of each active ingredient should generally be determined by its content, with the higher one in front and the lower one in the back; it can also be ranked according to its contribution to the efficacy, with the one that contributes the most to the efficacy being ranked in front; the third is the dosage form of the compound preparation, such as powder, emulsifiable concentrate, wettable powder, aqueous suspension, etc. For example, 3% methyl phthalate powder, 40% dimethoate emulsifiable concentrate, 20% cypermethrin emulsifiable concentrate, 50% polysulfur suspension, etc. If a synergist is added to the compound preparation, the synergist is not counted as an active ingredient, and the proportion it occupies does not enter the total content of the active ingredients. 304
