The pesticide such as palliative, binding agent, density adjuster and filler allow use and acceptable
Auxiliary element is all conventional in pesticidal preparations or allows the composition used, and is not particularly limited,
Concrete composition and consumption are determined by test according to recipe requirements.
Pesticidal combination of the present invention can be prepared as the multiple application being suitable in agricultural production using
Dosage form, reasonable dosage form has microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, moisture
Shot agent, wettable powder and ultra low volume liquids.
The production technology of the various application forms of described Pesticidal combination all belongs to existing known technology,
Do not repeat them here.
Product described in the invention can provide with the form of finished product preparation, i.e. each thing in compositions
Matter is the most blended.The composition of compositions can also the form of single dose provide, directly at tank before using
Or bucket mixes, it is then diluted to required concentration.
The frequency of administration of Pesticidal combination of the present invention and amount of application are with crops, insect, weather feelings
Condition changes and has small variations, can reach, by using suitable dosage, the mesh effectively prevented and treated
's.
Compared with prior art, it is an advantage of the current invention that:
1, ring bromine insect amide and trifluoro-benzene pyrimidine compound and have significant synergistic function, relatively
Single dose be used alone and significantly improve the prevention effect of insect on crops.
2, ring bromine insect amide and two kinds of active component of trifluoro-benzene pyrimidine compound, and decrease pesticide and make
Consumption, reduces use cost, alleviates the pollution to environment.
3, ring bromine insect amide and two kinds of active component of trifluoro-benzene pyrimidine compound, and the mechanism of action is the most not
Identical, action site increases, and has delayed the generation of pest resistance to insecticide, has added the use of pesticide
Life-span.

Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory virulence refers to
Number (TTI)] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient
(CTC) >=120 show as potentiation；Co-toxicity coefficient (CTC)≤80 shows as antagonism and makees
With；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as summation action.
Table 2, ring bromine insect amide and the trifluoro-benzene pyrimidine indoor joint toxicity measuring to Caulis et Folium Brassicae capitatae diamondback moth
Result
From table 2 it can be seen that ring bromine insect amide and trifluoro-benzene pyrimidine (are pressed at 20:1～1:20
Weight) proportion in compounding time, co-toxicity coefficient (CTC) is all higher than 120, to Caulis et Folium Brassicae capitatae
Diamondback moth all shows synergistic function；Ring bromine insect amide and trifluoro-benzene pyrimidine at 10:1～
In the proportion of 1:10 (by weight), synergistic function is the most notable, co-toxicity coefficient (CTC)
All more than 200.Visible, ring bromine insect amide and trifluoro-benzene pyrimidine be compounding has reasonability and can
Row.
In sum, a kind of killing containing ring bromine insect amide and trifluoro-benzene pyrimidine that the present invention provides
Worm compositions, obvious synergy, compared with existing unitary agent, prevent and treat crops
The effect of upper insect significantly improves, and to Crop securify, the lasting period is long, is worth in agricultural production
Upper popularization and application.
