Field Drug Testing is one of the main contents of the annual work of pesticide registration in my country: It is the important technical basis for determining the label of pesticide products, and the label is the only guide for the safe and rational use of pesticides. In order to standardize the internal efficacy test formula of pesticides, make the test more scientific and unified, and align with international standards, so that my country's efficacy test reports have international recognition, we have formulated our own national standards for efficacy test. This series of standards is similar to the standards of the European Mediterranean Plant Protection Organization (E11 Center) and the Food and Agriculture Organization of the United Nations (FAO), and is formulated based on the actual situation in my country and verified by a large number of field tests. The application of horse age is the same as the chemical method of preparing horse management. This part of GB/T17980 is specially formulated to determine the best treatment for different diseases, dosage, and methods of drug use, and to determine the impact on the yield and main quality of the horse and the safety of the current bell tickets, and to provide a basis for the efficacy evaluation and safe and reasonable use of the horse and the ticket. This part is based on the standard of the pesticide efficacy test (II) system, and the old part of the independent text is proposed by the Ministry of Agriculture of the People's Republic of China: This part was drafted by the National Institute of Standards and Technology for the Control of Pesticides. The main authors of this part are Wei Fuxiang, Zhang Fengzhong, Fei Fudong, Zhang Jia, Liu Xue, Qiu Xuelin, and Gan Xianfeng. This part is under the responsibility of the Institute for the Control of Drugs of the Ministry of Agriculture. 498
International Efficacy Test Guidelines (II)
Part 137: Test of Potato Sprouting Inhibitors
This part specifies the methods and basic requirements for the day-to-day efficacy test of potato sprout inhibitors. G/117980.137--2004
Not applicable to the registration of the efficacy test of the field efficacy test of potato sprout inhibitors. Other field efficacy test seasons shall be implemented according to the following parts:
2 Test conditions
2.1 Selection of crop and culture varieties
Record the age and culture type. This part is applicable to the efficacy tests of the whole-season crop and cannot be used for testing.
2.2 Selection of potato tubers
The potato tubers used in the test should be of the same variety and from the same source. The tubers should be dried under light soil and without mechanical treatment. All test individuals should be as uniform as possible.
2.3 Price conditions
The price conditions for the test materials should be consistent with the time during the test, and the price conditions should take into account the product characteristics: fast use, so that the price reduction conditions are kept in a reasonable state.
3 Test design and arrangement
3.1 Pharmaceutical
3.1.1 Test pharmaceutical
The generic name, Chinese name, trade name or formula code, dosage form and formula of the test pharmaceutical should be noted, and the manufacturer of the pharmaceutical should be indicated. The four doses of high, medium and low doses of the test drug are set to evaluate the safety of the test drug to crops), or the dose specified in the cooperative design (the test agreement agreed upon by the back-end trustee and the test product bearer). 3.1.2 Control drug
The control drug should be a product that has been registered and has been proven to have good efficacy in practice. In general, the type and dosage of the control drug should be close to that of the test drug, and the dosage should be the local common dosage. In special cases, the type of drug can be determined according to the schedule or according to the activity, and a blank control should be set. When the test drug is a cut-off dose, each single dose in the mixture should also be set as a control. 3.2 Plot arrangement
3.2.1 Plot arrangement
The test drug, the control drug and the blank control should be arranged randomly. 3.2.2 Plot treatment and strictness.
Each test site should be covered with at least 10 or 15 times of pesticide application per day. The number of times should be less than 1 time.
3.3 Application method
3.3.1 Application method
Application should be carried out according to the test requirements. The pesticide should be used in accordance with the characteristics of the harvested potatoes. The pesticide should be used at least 75 days after the harvest of potatoes and at least 195 days after the harvest.
C/T 17380.137—2004
The pesticide should be applied at any time before the natural separation of the potatoes. After the mature soil is matured, the pesticide should be applied in layers on the dry plots or sprayed on the potatoes. The treated potatoes should be stored in the ground. 3.3.2 Application time and frequency
Usually, the application time and frequency shall be carried out in accordance with the requirements of the agreement. The first application shall be carried out 15 days after the application, and the application period shall be recorded. If the interval is required, the interval between applications shall be recorded. 3.3.3 Application and water or
The dosage shall be in accordance with the dosage required by the agreement. Usually, it is expressed as / per ton of effective pesticide. The data shall be recorded. Water is expressed as 1./=.
3.3.4 Other requirements
During the test period, concentrated pesticides for controlling other pests and diseases and plant growth regulators shall be avoided. 4 Investigation and record of efficacy calculation method
4. 1 Meteorological materials
For the test conducted under natural storage conditions, the storage temperature and relative humidity shall be recorded at least once a week from the month of application. If necessary, the air components [carbon dioxide, ethylene, etc.] shall also be recorded. Tests conducted under cold storage conditions should also record the storage humidity and relative humidity. 4.2 Inspection method, time and frequency
4.2.1 Inspection time and frequency
Self-adhesive storage strips are used for inspection 15 days after treatment, and inspection is repeated until the end of the storage period. Storage conditions do not need to be adjusted after 4 days, and inspection can be resumed after storage. In the case of cold storage, inspection is repeated once every 12 hours until the end of storage. 4.2.2 Inspection method and frequency
31 tubers of pregnant potatoes are randomly selected from each treatment to inspect whether the buds have germinated at all, and the total number of buds and the number of buds that have germinated are inspected. The development of the buds is recorded separately.
4.2.3 Calculation method of drug efficacy
Precaution rate%=
Inhibition rate()
.3 Other effects on the whole block

For the annual investigation, the drug should be changed for the test tuber to produce the effect period, any influence of the drug on the tuber (such as the occurrence of spots, color changes: should be accurately recorded and described.
4.4 Other effects on the tuber (such as the occurrence of spots, color changes: should be accurately recorded and described. Biological effects Any signs of effects on other diseases and pests should be recorded, including whether they are beneficial or not. 4.5 Effects on product quality The test data should be analyzed using appropriate biostatistical methods and parameters (usually using the MRT method), and the efficacy prediction should be made in a formal format. The test report should be systematic and the report should make a conclusive evaluation of the test results. During the test, all original data should be kept for examination and verification.
