The formulations are prepared in a suitable apparatus or before or during administration.
Crop protection
The compound of formula (I) and component (B) may be administered in any desired order, in any combination, sequentially or simultaneously. In addition, in case the compound of formula (I) and component (B) are administered simultaneously, they may be administered as a composition comprising the compound of formula (I) and component (B).

The invention also relates to a method for controlling mite infestations of plants, plant parts and/or the environment by applying the active compound composition according to the invention to the plants, plant parts and/or the environment.
The treatment of plants and plant parts with the active compound compositions according to the invention is carried out directly or by acting on their surroundings using customary treatment methods. The conventional treatment methods are, for example, by dipping, spraying, atomizing, irrigating, evaporating, dusting, fogging, scattering, foaming, coating, spreading, injecting, watering, dripping irrigation.
Formula of efficacy of a combination of two compounds
The expected efficacy of a given combination of two compounds is calculated as follows (see Colby, s.r., "marketing Synergistic and antibacterial Responses of pharmacological compositions", weeds 15, pages 20-22, 1967):
if it is used
X is the control effect of the test compound A at a concentration of m ppm or m g/ha, expressed as a percentage of the untreated control,
y is the control effect of the test compound B at a concentration of n ppm or n g/ha, expressed as a percentage of the untreated control,
e is the control effect expressed as a percentage of the untreated control group using a mixture of A and B in m and n ppm or m and n g/ha,
then
E=X+Y-X*Y/100
If the observed control of the composition is higher than that calculated as "E", then there is a synergistic effect of the combination in killing.
Example A miticide test on Tetranychus urticae
Dissolving the raw medicines of the compound shown in the formula (I), clofentezine and bifenazate respectively with a solvent to prepare a single-dose mother solution, and then diluting the mother solution to a required concentration by using an aqueous solution containing 0.1 percent of Tween-80.
The spider mites to be tested are female adult mites which are consistent in size, healthy and active. The leaves to be tested were healthy, intact and of consistent size. Cotton leaves were punched with a punch into a leaf disk with a leaf surface diameter of 2 cm. Placing a wet sponge block in the culture dish, placing filter paper on the wet sponge block, and placing butterfly on the filter paper for later use. And inoculating the two-spotted spider mite into the solution. Each leaf disc was inoculated with 20 female adult mites.
The treatment was carried out using a POTTER spray tower. The amount sprayed was 2ml per treatment. After treatment, the cotton leaves are placed at a temperature of (25 +/-1) o C, relative humidity (70 +/-10)%, light irradiation ratio L: d is 16:8 in a thermostatic chamber. Each treatment was repeated 3 times. After 2 days the death of the adult mites was observed. The non-responders were considered dead by touching the spider mite's feet and mouth with a small brush nib. To contain a solvent and an emulsifierThe clear water of (1) is used as a control.
The tetranychus urticae mite reduction rate and the control effect of each treatment are calculated according to the following formulas:
the reduction rate of live mites (%) = (number of live mites before application-number of live mites after application)/number of live mites before application × 100
Control effect (%) = (reduction rate of live mites in medicament treatment area-reduction rate of live mites in control area)/(100-reduction rate of live mites in control area) × 100
In addition, the theoretical control effect (%) can be calculated by the Colby formula. When the actual controlling effect (%) is higher than the theoretical controlling effect (%), the composition of the present invention has a synergistic effect.
TABLE 1
Figure 602104DEST_PATH_IMAGE002
The good control of the active compound combinations according to the invention is evident from the above table 1 examples. Although the individual actives are less effective, the compositions show efficacy exceeding the sum of simple efficacy. A synergistic effect exists when the effect of the active compound combination is greater than the sum of the control effects of the active compounds administered alone.
