1 Scope
Guidelines for Pesticide Efficacy Tests
Part 6: Pesticides for Control of Vegetable Thrips
This part specifies the methods and basic requirements for field plot tests of insecticides for control of vegetable thrips. NY/T1464.6-2007
This part applies to field plot tests and efficacy evaluation of insecticides for control of palm thrips (1hripspami), yellow thrips (Thripsftans), tobacco thrips (Thripstabari), onion thrips (Thripssaltinrum), etc. on fruits, melons, onion and garlic vegetables and cruciferous vegetables. Other field efficacy tests shall refer to this part for implementation. 2 Test conditions
2. 1 Test objects and crops
The test object is chrysanthemum thrips that harm vegetable crops. Record the main insecticide species, incidence rate and development stage of the test site. The test crops are fruits, melons, onion and garlic vegetables and cruciferous vegetables: record the name of the crop variety. 2.2 Test conditions
The test site should be selected with obvious pest damage and the damage degree is consistent. The cultivation conditions (soil type, fertilization, tillage row spacing) of all test plots must be uniform and consistent, and meet the local good agricultural practices. 3 Test design and arrangement
3. 1 Test treatment
3. 1. 1 Pesticide
3. 1. 1. Test pesticide
The test pesticide needs to have 3 or more treatments, or set up according to the requirements of the agreement. Record the generic name (Chinese, English) or code of the pesticide, dosage form, content, manufacturer and treatment dosage (expressed in effective concentration mg/kg or mg/L). 3.1.1.2 Control drugs
Control drugs must be registered and proven effective in practice. Their types and modes of action should be similar to those of the test drugs. Control drugs are used at the local conventional dosage. The test drug is a single drug. At least one local commonly used single drug is used as a control drug: When the test drug is a mixture, each single drug in the mixture is used as a control drug. It must also contain a local commonly used drug as a control drug. The generic name, dosage form, content, manufacturer, and dosage of the control drug are recorded. 3.1.2 Blank control
Set no pesticide treatment as the empty control,
3.2 Repetitions
Each treatment shall be repeated at least 4 times,
3.3 Plot arrangement
3.3.1 Plot area
The plot area shall not be less than 20)㎡, with 20㎡～40㎡ as the base. 3.3.2 Plot arrangement
Plots are generally arranged in random blocks, and the plot arrangement diagram is recorded. 1
NY/T1464.6—2007
3.4 ​​Requirements for pesticides used to control pests other than the test object If other pesticides are needed to control diseases, insects, and weeds other than the test object during the test, the pesticides that have no effect on the test pesticides and the test object shall be selected, and they shall be used separately from the test pesticides and control pesticides, and all test plots shall be treated uniformly. Record the exact data of the application of such pesticides (name of pesticide, content, dosage form, production environment, application amount, application method, application time, etc.). 4 Application
4.1 Application equipment
Use common equipment for application according to the dosage form of the test pesticide, or carry out according to the requirements of the agreement, and record the type and operating conditions of the application equipment. 4.2 Application method
Carry out according to the requirements of the agreement and the instructions on the label, and the application should comply with local good agricultural practices. 4.3 Application time
Carry out according to the requirements of the agreement, or determine according to the appropriate period of control of vegetable shaving (with insects as hair), generally, the number of nymphs per 15 pieces of 3 leaves is not less than 300, record the date of application and the growth period of the crop at the time of application. 4.4 Number of applications
Carry out according to the requirements of the agreement and record.
4.5 Application amount
Determine the application amount according to the application method, crop growth period, and plot area, or carry out according to the requirements of the agreement. Record the application time, expressed in I./hr\.
5 Investigation
5.1 Effect investigation
5.1.1 Investigation method
Select 15 to 30 leaves from the middle and upper parts of melons, solanaceous vegetables, and cruciferous vegetables in each plot, and select 15 to 30 leaves from each plot of onion and garlic vegetables, and check the number of live insects. 5.1.2 Investigation time and frequency
Investigate the insect population base before application (the number of live nymphs before application). Check the number of residual insects on the 1st, 3rd, 7th, and 10th day after application (the number of live insects after application): For slow-acting or long-lasting pesticides, the investigation time can be extended or the number of investigations can be increased. 5.2 Direct impact on crops
Observe whether the pesticide has any damage to the crop. If there is any damage, record the symptoms, type, and degree of damage. In addition, the beneficial effects on crops (such as accelerated maturity, increased vitality, etc.) should also be recorded: record pesticide damage in the following way:
If the pesticide damage can be counted or measured, it should be expressed in absolute numbers, such as plant height. - In other cases, the extent and frequency of pesticide damage can be estimated by the following two methods: 1) According to the pesticide damage grading method, record the pesticide damage situation in each plot, expressed as one, two, three, four, five. Pesticide damage grading method:
-1: No pesticide damage;
-2: Mild pesticide damage, visible damage, does not affect the normal growth of crops;
-3: Obvious pesticide damage, can be recovered, will not cause crop yield reduction;
-4: Severe pesticide damage, affecting the normal growth of crops, causing a certain degree of loss to crop yield and quality, generally requiring compensation for part of the economic losses;
-5: Severe pesticide damage, crop growth is hindered, crop yield and quality are seriously reduced, The economic loss must be compensated. 2) Compare the pesticide-treated area with the blank control area and evaluate the percentage of pesticide damage. At the same time, the pesticide damage symptoms of the crop should be accurately described2
(dwarfing, chlorosis, deformity, etc.), and provide physical photos, videos, etc. 5.3 Impact on other organisms
5.3.1 Impact on other pests and diseases
Any impact on other pests and diseases should be recorded, including beneficial and unbeneficial impacts. 5.3.2 Response to other non-target organismswwW.bzxz.Net
Record the impact of the pesticide on wild organisms and beneficial insects in the test area. 5.4 Other information
5.4.1 Meteorological data
NY/T 1464.6—2007
Record the meteorological data of the test site during the entire test period, including rainfall (rainfall type and daily rainfall, expressed in mm), temperature (daily average temperature, highest and lowest temperature, expressed in mm), humidity (highest and lowest humidity, expressed in %), etc. 5.4.2 Soil data
Record the soil type, soil fertility, irrigation conditions and soil cover such as weeds. 6 Calculation formula and data analysis
Calculate the control effect according to the following formula, and apply the biostatistics method (LMR method) for statistical analysis. CK.X PT!
PT =(1-CK,PT.))
Control effect, unit is fraction (%): PI. - The number of live nymphs in the pesticide-treated area before application, in heads; PT,-
- The number of live nymphs in the pesticide-treated area after application, in heads; The number of live nymphs in the blank control area before application, in heads; CK—
The number of live nymphs in the blank control area after application, in heads. CKI—
