Description
Technical field
The invention belongs to technical field of pesticide, contain trifluoro-benzene pyrimidine, rotenoid more particularly to a kind of
Insecticide composition.
Background technique
Rice is China's staple food crop, and rice hoppers are one of main 3 major pests of hazard rice, belongs to Homoptera
Plant hopper.There are 3 classes, respectively brown paddy plant hopper, Sogatellafurcifera and small brown rice planthopper, wherein especially brown paddy plant hopper and small brown rice planthopper are to rice seed
It plants and constitutes serious threat, cause the dried-up lodging of rice large area, rice yield direct losses 10-20%, individual serious fields
Even No kernels or seeds are gathered, as in a year of scarcity.
Currently, the compounded pesticides of prevention and treatment rice hoppers mainly have imidacloprid and Cupric sulfate, dimehypo, chlopyrifos or
The formula of the pesticide compositionals such as Diacloden and avermectin, Nitenpyram, chlopyrifos.The long-time service of right imidacloprid etc., resistance
Increase quickly, control efficiency constantly declines, only increase dosage, can be only achieved remarkable result.But also improve agricultural production
Cost increases the influence to environment.Especially imidacloprid especially influences ecological chain balance to the bee colony high poison for propagating pollen.Cause
Whether this relevant department continues to use with regard to it, there is very big dispute.Furthermore some countries are also with regard to nicotinic insecticide pyrrole in the world
Worm quinoline carries out environmental risk evaluation, review.
Trifluoro-benzene pyrimidine is novel mesoionic class or amphoteric ion insecticides, is also new pyrimidine ketone compounds, tool
Have efficiently, holding effect, dosage is low, it is environmentally friendly the features such as, be mainly used for rice, cotton, corn and Soybean and Other Crops, to same
Wing mesh, Lepidoptera etc. have good preventive effect.Have in particular for plant hopper, aphid, thrips, noctuid, diamondback moth particularly preferred
Effect.Though it acts on nAChR, from anabasine insecticide have the different mechanism of action, be only one can inhibit and
The compound of inactive nicotinic acetylcholine receptor.Maximum feature is had no adverse effect to insect pollinator, and imidacloprid can be overcome
Equal nicotinic insecticides are to insect pollinator critical defect.Trifluoro-benzene pyrimidine belongs to ultra high efficiency insecticide, prevents and treats rice hoppers, spray
Mist uses, and effective ingredient consumption is only 15-22.5 grams/ha (i.e. 1-1.5 grams/acre), energy high-efficient and lasting prevention and treatment larva and adult,
Lasting period is 7-10 days longer than similar product.
Rotenoid is that a kind of substance with insecticidal activity separated is extracted from plants in people, is
One of three great tradition plant insecticides.Its insecticidal mechanism is the complex I for making in Mitochondrial electron respiratory chain, and electronics is inhibited to pass
Pass process.It is low to non-target organism toxicity, influence small, light-exposed easy decomposition in the environment, noresidue, and to Environmental Ecological Balance without
The characteristics of adverse effect, dosage is low, safety.
In conclusion solve these problems it is critical that seeking new insecticide carries out scientific compounding, have reached and delay
Resistance, raising preventive effect, expansion insecticidal spectrum and other effects.It has no at present about trifluoro-benzene pyrimidine and rotenoid compounded combination
Object.

Thin record, calculates preventive effect, the results are shown in Table 6.
Table 6 prevents and treats rice planthopper pharmacodynamic test result
As seen from the table, formula synergistic effect is significant in the present invention, improves practical control efficiency, effectively delays test worm anti-
Property generate.Action advantage is complementary, and rotenone is quick-acting fast, and holding effect is short, and early period, preventive effect was high, and preventive effect weakens after 7 days；Trifluoro-benzene pyrimidine is held
Effect length, the two science compounding, Synergistic insecticidal compositions preventive effect are obviously improved, and lasting effect is long.Compared with single dose, reduce activity
Ingredient Amount, save the cost substantially reduce Drug level, mitigate environmental pollution.
