insecticides for pesticide registration
Order of the General Administration of Quality Supervision, Inspection and
Quarantine (No.75) - “Measures for the Metrological Supervision and
Administration of Quantitatively Packed Commodities”
Order of the Ministry of Agriculture and Rural Affairs of the People’s Republic
of China [2007] (No.10) - “Pesticide registration information requirements”
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 active ingredient
Chemical composition with biological insecticidal activity.
3.2 efficacy
Under the specified conditions and within the specified time, the effect of
repelling (killing) mosquitoes (including flies, cockroaches, ants and so on) the
product shall achieve.
3.3 median knockdown time, KT50
Under the specified conditions, the time required for 50% of the test insects to
be knocked down (i.e., fall down).
3.4 minimum effective period
The minimum effective time for the use of the traditional Chinese medicine liquid
of electrothermal mosquito liquid incense and electric heater.
4 Requirements
4.1 Requirements for use of active ingredient
It shall be the medicament that is registered for use in accordance with relevant
national regulations.
4.2 Toxicology
It shall meet the toxicological test requirements of the corresponding dosage
form in the Order of the Ministry of Agriculture and Rural Affairs of the People’s
Republic of China [2007] (No.10).
4.3 Active ingredient content and allowable fluctuation range
4.3.1 The content of active ingredients shall be clearly stated on the product
packaging.
4.3.2 The allowable fluctuation range of active ingredient content is shown in
Table 1 and the following regulations:
a) For mosquito coil, cockroach, fly incense and other tobacco preparation
products, the allowable fluctuation range of its active ingredient content
shall not be higher than 40% of the indicated value and not lower than 20%
of the indicated value;
b) For electrothermal mosquito liquid incense, the allowable fluctuation range
of its active ingredient content shall not be higher than 25% of the
indicated value and not lower than 10% of the indicated value;
c) Electrothermal mosquito tablet incense shall be marked (mg/piece). The
5.3 Active ingredient content and allowable fluctuation range
5.3.1 Visual inspection.
5.3.2 The content of active ingredients shall be tested in accordance with the
provisions of Annex A, Annex B, Annex C, and Annex D (unlisted dosage form
products shall be implemented according to the test methods in relevant
national standards).
5.4 Efficacy
5.4.1 Sprays, aerosols, small aerosols, mosquito coils, electrothermal mosquito
tablet incenses, electrothermal mosquito liquid incenses, cockroach poison
baits shall be tested according to GB 13917.1 ~ 13917.7.
5.4.2 Toxic powder, poison pen and repellent are tested according to GB/T
17322.9 ~ 17322.10.
5.4.3 Unlisted dosage form products are implemented according to the methods
in relevant national product standards.
5.5 Thermal storage stability
5.5.1 Mosquito coil
Take one coil from the middle of one box of test samples to crush. Pass the
0.154mm (100 mesh/inch) standard sample sieve. Take half of it and seal it in
a Teflon reagent bottle (the other half is tested for active ingredient content).
Then place it in a thermostat at (54±2)°C for 14d. After taking out the sample,
test and calculate the degradation rate according to the method for determining
the content of active ingredient within 24h.
5.5.2 Electrothermal mosquito tablet incense
The test sample shall be the electrothermal mosquito tablet incense in the same
row as before storage. The test sample (with aluminum foil packaging) is placed
in a (54±2)°C thermostatic chamber for 14d. After taking out the sample, test
and calculate the degradation rate according to the method for determining the
content of active ingredient within 24h.
5.5.3 Electrothermal mosquito liquid incense
Take a part of a bottle of test sample as the active ingredient content. Screw
the outer cover of the rest part into the original packaging. Then place in a
(54±2)°C thermostatic chamber for 14d. After taking out the sample, test and
calculate the degradation rate according to the method for determining the
content of active ingredient within 24h.
Liquid medicine is poured into a measuring cylinder or weighed with a balance.
Read out the test value (measuring cylinder division value: 0.1mL; balance
division value: 0.1g).
5.9 Internal pressure of insecticide aerosol
5.9.1 Instruments
5.9.1.1 Pressure gauge: range is 0~1.6MPa, accuracy is level 2.5.
5.9.1.2 Special joint.
5.9.1.3 Timer.
5.9.1.4 Constant temperature water bath: temperature control accuracy is ±2°C.
5.9.2 Test steps
Correctly press the valve actuator according to product description
requirements. Eliminate the air trapped in valves and straws. Then place the
sample in a (55±2)°C water bath. Immerse the water to four-fifths of the height
of the tank. Maintain it at the constant temperature for 30min. Wear thick leather
gloves. Remove the sample and dry it quickly. Unplug the valve actuator. Align
the pressure gauge inlet with the valve stem. Press hard. After the pressure
gauge pointer stabilize...
