GB/117980,662004
is one of the important documents for the registration and management of pesticides in China. It is the key technology for the formulation of pesticide product standards, and the standard is a guide for the safe and effective use of pesticides. It is to standardize the day-to-day test methods and content of pesticides, make the test requirements consistent with the scientific and standardized, and connect with the national standards. my country's day-to-day efficacy test has international recognition, and has established national standards for day-to-day efficacy test. This series of standards is based on similar standards of the European and Mediterranean Plant Protection Association (PPA) day-to-day efficacy test standards and the Asia-Pacific region of the Agricultural Organization (FA). It is formulated based on the actual pesticide efficacy test results of large-scale organizations. The leaf snake is not harmful to vegetables. It is produced by the Ministry of Agriculture and Rural Affairs. Insecticides should be used for prevention and control during the production period. In order to determine the research basis for the control of vegetable leafminers, the effects of pesticides on crops and non-target beneficial organisms, and provide a basis for the certification of pesticides for animal safety and management, this part (H/17S80) is specially formulated. This part is one of the standards for pesticide efficacy test (II), but it is an independent part. The unit of this part is the Ministry of Agriculture. The main drafters of this part are Tao Fengmei, Mi Yongren, Li Siren, Lai Huiming, Shi Yipu, Ji Lue. The Ministry of Agriculture Pesticide Inspection Institute is responsible for the interpretation of this part. 1 Scope
Standards for efficacy test (II)
Part 66: Pesticides for the control of vegetable leafminers GB/T 1798C.662004
This part defines the traditional method and basic requirements for the field efficacy test of pesticides against foliage. This part is for the field efficacy test of pesticides against foliage (Cucurbitaceae, Solanaceae, Leguminosae), flowers (Manchuria, chrysanthemum, etc.), American soft fly (L. haiaobrenas) on tobacco, and the efficacy evaluation of pesticides on leaf segments:
2 Test conditions
2.1 Selection of test objects, crops and varieties 2.2 Environmental conditions
The test should be conducted in areas where cucumbers, tomato, and beans are grown. The cultivation conditions (such as materials, crop conditions, row spacing, and water depth) of the test plots should be consistent and in accordance with local scientific agricultural practices (GAP) 3.1 Test agents
3.1.1 Test agents
The trade name or code name of the agent, the generic name , Chinese name, dosage form contains "production benefits", the trial treatment is not less than three doses or the dosage specified in the agreement.
3.1.2 Control drug
The control drug should be a product that has been registered and proven to have good efficacy in practice. In general, the type and effect of the test drug should be or should be similar to the test drug. Local commonly used drugs should be used. Special circumstances depend on the date of the trial. 3.2 Plot arrangement
3.2.1 Plot arrangement
The test drug, control drug and blank should be arranged in a small area at a certain point. Special circumstances should be noted. 3.2.2 Area and complexity of plots
The plot size is 15--=m2, the number of plants in the plot should be set to 2~, and the perimeter should not be less than 8m. The number of repetitions: at least one repetition in the room, and 3 times when using a single room. 3.3 Methods of spraying
3.3.1 Method of use
The spraying should be adapted to scientific agricultural practice: the spraying method is usually indicated on the label or carried out according to the requirements of the agreement. 3.3.2 Equipment
Choose suitable equipment and ensure that the amount of medicine is accurately distributed and evenly mixed: if there is a difference of more than [C% between the two amounts, it should be recorded. Provide full information on the type of equipment used and the operating conditions (operating pressure, spray orifice, etc.). 1
GB/T17980.66—2004
3.3.3 Application times
The application time and the time of application shall be indicated on the label, or carried out according to the agreement. The first application should be carried out when there is enough softness at 1-2 years old: for prevention and control of adult electricity, the sampling rate should be high, preferably early or late: sufficient sulfur production: the first application date should be recorded according to the table, and the crop development stage should be recorded. 2.3. 4 Dosage and volume || tt || Use according to the requirements of the instrument and the dosage indicated on the label. The total amount of the drug should be expressed as shm (g:kg). When purchasing, the amount of the drug should be recorded. 3.3.5 For pesticides for the control of other diseases and insect pests, other pesticides should be used quickly. Select the pesticides that are incompatible with the test agents and the test objects, and treat all the plots in the same way. And use them separately with the test agents so that the resistance of these pesticides is minimized. The accurate data of the agent used for evaluation and recording shall be recorded.
4 Investigation, recording and measurement methodsbzxZ.net
4.T Meteorological and soil data
4.1.1 Meteorological data
Record the rainfall during the test period (type and daily rainfall in terms of rainfall and average temperature, low temperature, and decline in rainfall). The data should be taken from the nearest meteorological station or the test site to record the adverse weather conditions that may affect the test results during the test period, such as heavy or long-term dry weather, etc. 4.1.2 Soil data
Record the data on soil type, soil fertility, and the beneficial effects of tea plants. 4.2 Investigation methods, time and frequency
4. 2. 1 Investigation methods
10 samples were collected in each plot. Each forest was selected, and 13 leaves were selected! The leaf should be in the growth stage (length 05-1c) (this point is in the 1-2 year old period) and the leaf should be 1cm away from the palm of the hand. Use oily agent to mark each point so that the front end is on the line. Leaf with empty history should not be selected. When investigating the prevention effect, the leaf should be fresh, full of holes, alive, and dead. If it is difficult to distinguish, it can be said that the leaf is effective if it is extended, has a unique eclosion, and has a new leaf. 4.2.2 Investigation time and situation
The drug contains sitting effect · 3, 7, d after drug application, record the dead insect effect, live insect effect 4.2.3 Efficacy calculation method
Efficacy technology (1) to formula (3) calculation:

Observe whether the crop needs pesticides, record the type and extent of pesticide damage. In addition, record the effect of the crop on the crop (such as maturity, increase in yield, etc.). If the pesticide can be effective or measured, use absolute values ​​to express the height. 2
In other cases, estimate the extent of pesticide damage according to the following method: GB/T 17980.66—2004
1) According to the pesticide classification method, record the pesticide damage of each plot, expressed as 1, 2, 3, 4, 5, 6, 7, 8. The pesticide damage classification formula is as follows:
10, 10, 20, 30, 40, 50, 60, 70, 80.
