The invention provides a compound insecticide for preventing rice planthopper. The compound insecticide comprises pyridaben and fenobucarb serving as effective components, wherein the mass ratio of the pyridaben to the fenobucarb is 4:1 to 1:128. The compound insecticide has the advantages of synergism, few dosage, wide range of prevention objects, reduction of medication cost and alleviation of environment pollution.
Description
Technical field
The invention belongs to the Chemical Control of Harmful Insects field, be specifically related to a kind of compounded pesticides of preventing and treating rice hoppers.
Background technology
Pyridaben, adopted name: Pyridaben, chemical name: 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-3(2H)-pyridazinone, be a kind of heterocyclic insecticidal/acaricidal agent.Be widely used in control various tetranychids, aleyrodid and aphid on the crops such as oranges and tangerines, apple, cotton and tealeaves.
Bassa, adopted name: Fenobucarb, chemical name: o-sec-butyl phenyl methyl carbamate, carbamates insecticidal/acaricidal agent for commonly used has the infiltration translocation to plant, and insecticidal action is fast, ovicidal and systemic action are arranged, under low temperature condition, still have good insecticidal effect.Be applied to prevent and treat on the crops such as paddy rice, cotton the insects such as plant hopper, leafhopper, cotten aphid, cotton bollworm.
Rice fulgorid, comprise brown planthopper Nilaparvata lugens, white-backed planthopper Sogatella furcifera and small brown rice planthopper Laodeobhax striatellus, be migratory pest, in national paddy fields distribution is arranged all, it is one of primary pest of rice crop, except self harm to paddy rice, 5 kinds of viruses that they propagate: rice grassy stunt virus (RGSV), paddy rice tingia stunt virus (RRSV), oryza virus 3 (RSV), rice black-streaked dwarf virus (RBSDV), southern rice black-streaked dwarf virus (SRBSDV) has a strong impact on the quality and yield of paddy rice.Begin from phase late 1960s, the virus disease of rice fulgorid and biography band thereof just is one of key factor that affects the Asia Rice Production always.
For a long time, people are mainly with the chemical pesticide control rice fulgorid, institute's with medicament is mainly anabasine, organic phosphates, carbamates and Avermectin etc., but long-time a large amount of use of insecticide blindly, the in addition biological property of rice fulgorid self, caused the rice fulgorid resistance level constantly to improve, medicament commonly used now can't obtain good control efficiency.Thereby searching is safe, alternative medicament more and more seems important efficiently.
The synergistic complex of agricultural chemicals is to enlarge the chemical control scope, improve desinsection quick-acting and lasting effect, delay the effective measures of pest resistance to insecticide, still finds no up to now the relevant report that the insecticide acaricide composition of pyridaben and Bassa is used for preventing and treating rice fulgorid.
Summary of the invention:
The purpose of this invention is to provide a kind of compounded pesticides of preventing and treating rice hoppers, by being mixed of pyridaben and Bassa, make compounded pesticides, be used for preventing and treating rice fulgorid, effective, dosage is low; And the method that provides the application said composition to prevent and treat the insects such as rice fulgorid, Bemisia tabaci.
The technical solution used in the present invention is as follows:
A kind of compounded pesticides of preventing and treating rice hoppers is characterized in that: be made of active ingredient pyridaben, Bassa and auxiliary material component, wherein, the mass ratio of pyridaben and Bassa is 4:1 ~ 1:128.
In the described compounded pesticides, the mass ratio of pyridaben and Bassa is 4:1 ~ 1:4.
In the described compounded pesticides, the mass ratio of pyridaben and Bassa is 1:1 ~ 1:2.
The formulation of described compounded pesticides is missible oil, suspension emulsion, water-dispersible granules or wetting powder.
Pyridaben is the heterocyclic insecticidal/acaricidal agent, and mite class, aleyrodid and aphid are all had preferably effect, knocks down rapidly, and the lasting period is long.
The Bassa insecticidal action is fast, and ovicidal and systemic action are arranged, and plant is had the infiltration translocation, but the lasting period is short.
Pyridaben and Bassa are carried out compositely can improving drug effect, expanding prevention scope, prolong drug effect, reduce consumption.
Using method: with the medicament of preparation by can conventional spraying after 1000 or 2000 times of dilutions, atomizing, perhaps utilize the big machineries such as hot mist machine, aircraft to carry out the large tracts of land dispenser, reduce the generation of the insects such as rice fulgorid.
It is good that the present invention is used for control rice fulgorid preventive effect, finds that also pyridaben and Bassa are mixed, and the insects such as Bemisia tabaci, cigarette aphid, cotten aphid, pear sucker are had excellent preventive effect.
The invention provides and a kind ofly be mixed by medicament, improve drug effect, the method for control rice fulgorid.With the medicament of preparation by can conventional spraying after 1000 or 2000 times of dilutions, atomizing, perhaps utilize the big machineries such as hot mist machine, aircraft to carry out the large tracts of land dispenser, reduce the generation of the insects such as rice fulgorid.
Beneficial effect of the present invention:
Pesticidal combination of the present invention compared with prior art, produce following beneficial effect: (1) is compared with single dose, said composition has obviously improved control efficiency to the insect notable synergistic, has significantly reduced drug cost; (2) insect is difficult for developing immunity to drugs to this medicament, has also suppressed the resistance of insect to other agricultural chemicals simultaneously; (3) insect is had concurrently quick-acting and long-acting function; (4) can significantly reduce the field dosage, effectively environmental contamination reduction and residue of pesticide; (5) compare with other medicaments commonly used, produce and the use cost reduction; (6) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (7) reduced toxicity to other non-target organisms.
Experimental data
One, reagent agent: the former medicine of pyridaben; The former medicine of Bassa
Two, for the examination insect: the paddy rice small brown rice planthopper; Brown Planthopper
Three, assay method:
The method that adopts indoor bioassay and field control effectiveness test to combine.
At first draw the built agent of different proportionings to the co-toxicity coefficient of paddy rice small brown rice planthopper and brown planthopper by indoor bioassay, again by clear and definite its control efficiency of field control effectiveness test, determine formula rate and the optimum amount of built agent.
Indoor bioassay: adopt the glass-tube medicine embrane method.Former medicinal acetone diluted is become series concentration, accurately measure liquid 0.5 mL with 0.5 mL pipette, the adding capacity is (standard test tube) in the teat glass of 20 mL, lie against it on experimental bench and constantly rolling, make the acetone volatilization, medicament forms the medicine film at the glass-tube inwall, compares with the glass tube that only adds the acetone film forming, and every concentration repeats 4 times.30 of consistent adults are grown in access in every pipe, and the mouth of pipe seals with the spun yarn net and court has a down dip 35
oPlace, 5 h check dead, the borer population of living after processing.With SPSS 17.0 statistical software deal with data.
Field effect: have the prescription of synergistic effect to make missible oil (EC), suspension emulsion (SE), wetting powder (WP), water-dispersible granules (WDG) the indoor bioassay gained and test.After the residential quarter is set sprays medicament, the dosage that check preventive effect and determining is fit to.
Table 1, table 2 have provided respectively 5 kinds of medicaments to the virulence test result of striatellus imago, brown planthopper adult;
Can find out that by table 1 and table 2 pyridaben has shown good virulence to small brown rice planthopper and brown planthopper, Bassa is slightly poor to the virulence of small brown rice planthopper and brown planthopper.
