Abstract
The present invention relates to the Pesticidal combination that a kind of suitable trickle irrigation prevents diaphorina citri, active ingredient is sulfoxaflor and bromine cyanogen insect amide binary built.The insecticides indoor biometrics are 5 to the best synergic ratio of diaphorina citri:3.The advantages of composition of the present invention, is：With apparent synergistic effect；Insecticidal spectrum is expanded, the drug resistance of pest is delayed；Reduce dosage；Reduce pesticide residue；Save drug cost and labor cost simultaneously.It is uneven that the composition trickle irrigation dispenser prevention diaphorina citri can solve medicament sprinkling existing for spray pesticide；Shelter wood louse can not prevent；The problem of spraying time and spraying times are unable to control.The composition orientation is applied to crop root region by existing drip irrigation system, transporting is absorbed to the tender position of Citrus leaf children by root system, prevention diaphorina citri can be oriented.
Description
Technical field
The present invention relates to the preventions of diaphorina citri, belong to technical field of pest control.
Background technology
The adult and nymph of diaphorina citri directly suck the phloem sap of the bud tip, not only influence the normal life of citrus plant
It is long, and propagate Citrus Huanglongbing pathogen during feeding.Susceptible tree tree vigo(u)r decline, gradually loses bearing capacity, final tree body is dead
It dies.Diaphorina citri and yellow twig become a great problem for restricting Citrus Industry sustainable development all over the world.Chemical prevention at present
Diaphorina citri is to administer the important measures of Citrus Huanglongbing pathogen.
The generation of diaphorina citri and mandarin tree pumping hair young sprout are closely related, and Citrus leaf is more dense, to accomplish full side
Position, efficiently, prevent diaphorina citri for a long time, can just make mandarin tree from its evil.Spray pesticide prevent diaphorina citri exist with
Lower problem：Medicament sprinkling is uneven, and the wood louse in shelter is difficult to prevent；Spraying time and spraying times are difficult to control；Medication
Spend frequent and ineffective, drug resistance and environmental pollution are serious etc..
Trickle irrigation dispenser is transported to crop root region by existing drip irrigation system, by pesticide by droping irrigating pipe.
Compared with foliar spray, trickle irrigation dispenser has many advantages：Insecticide is absorbed by root system, can realize orientation transporting distribution；
Pesticide efficacy is high, and the lasting period is long；It can replace foliage application or reduce blade face dosage；Reduce Pesticide use input at
This（Cost of labor, fuel oil take）；Mitigate damage of the machinery to soil packing and to crop；Reduce the shadow to non-target organism
Ring etc..
Sulfoxaflor（Sulfoxaflor）It is the anabasine insecticide developed by The Dow Agrosciences, LLC., structure
Belong to sulfoximide class.Its mechanism of action is nicotinic acetylcholine esterase receptor（nAChR）Agonist, but with anabasine
Other insecticides are compared, which is incorporated into action target spot in a completely different way, by the resistance to insecticides committee（IRAC）Recognize
It is set to Group 4C classes.There is no interact sulfoxaflor with other insecticides of organophosphor, carbamate and anabasine
Resistance plays an important roll pest resistance to insecticide improvement.Sulfoxaflor can effectively prevent sucking pest, including aphid
Worm, aleyrodid, thrips, scale insect etc..Sulfoxaflor has superior absorbability, after being absorbed by root system extremely by xylem transporting
The tender position of children on the ground.
Bromine cyanogen insect amide（Cyantraniliprole）Also known as cyanogen insect amide, be by E.I.Du Pont Company after Rynaxypyr
A kind of Novel ortho formamido benzamide insecticides that success is developed, act on ryanodine receptor.With Rynaxypyr
It compares, bromine cyanogen insect amide has wider array of insecticidal spectrum.Bromine cyanogen insect amide can not only effectively prevent Lepidoptera, Diptera, elytrum
Mesh pest, and there is higher activity to Hemipteran pest.Bromine cyanogen insect amide systemic activity is preferable, pouring root can be used, at soil
The occupation modes such as reason and seed treatment.The medicine shows significant poor selectivity to the ryanodine receptor of mammal and pest
It is different, substantially increase the safety to mammal, other vertebrates and natural enemy.
So far, the report of the insecticides prevention diaphorina citri of sulfoxaflor and bromine cyanogen insect amide is not yet found
Road.The composition is subjected to dispenser by way of trickle irrigation, to realize the purpose of comprehensive, efficient long control diaphorina citri.
The Pesticidal combination rational mixture not only has apparent synergistic effect, and can reduce the drug resistance of pest, reduces simultaneously
Dosage and pesticide residue, trickle irrigation dispenser is easy to operate, saves labor cost.
