Abstract
The invention relates to a high-efficiency and low-poison comosite insecticidal composition containing triaguron. The insecticidal composition comprises triaguron, chlorpyrifos, accessory ingredient and excipient and is prepared to water emulsion or microemulsion, and the weight ratio of the triaguron and the chlorpyrifos is 1:1 to 10. The insecticidal composition has higher synergy functions and fast insecticidal speed, stays pest resistance, enlarges the preventing spectrum,, and reduces drug costs and lightens toxicity. The invention is used for preventing and curing homopteran pests on fruit trees, vegetables, paddy, cotton and wheat and can be especially used for preventing and curing rice fulgorids, plant louses and white flies with the effect obviously higher than single dosage use.
Description
Technical field
The invention belongs to technical field of pesticide, being specifically related to a kind of is the Synergistic insecticidal compositions of main active with triaguron and chlopyrifos.
Background technology
Triaguron, english common name triazamate, outward appearance is a white powder, molecular formula C
13H
22N
4O
3S, chemical name is: (3-tertiary butyl-1-dimethylamino formyl-1H-1,2,4 ,-triazole-5-base sulphur) ethyl acetate.
Triaguron belongs to the high selectivity systemic insecticide, and cholinesterase is had rapid inhibitory effect, and is through the suction-operated and the contact action of aphid splanchnopleure, all effective to the various aphids on the various crop population.Dosage with the conventional control aphid is invalid to diptera and lepidoptera pest.To useful insect and honeybee safety.
Chlopyrifos: English name: (chlorpyrifos), molecular formula: C
9H
11C
13NO
3PS chemical name: O, O-diethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate.
Chlopyrifos have good tag, stomach toxicity and fumigation action.A dispenser can prevent and treat the various pests on the crop, insects such as leaf roller, coccid and leaf-roller is had outstanding especially preventive effect, and can be used for preventing and treating soil insect, domestic animal vermin and sanitary insect pest.To compare toxicity low, safe in utilization with conventional organophosphorous pesticide, little to the influence of natural enemy population, is difficult for producing resistance.
At present, the restriction increasingly stringent that both at home and abroad organic solvent is used, some national xylol has disabled trend, thereby the formulations of pesticide will be brought in constant renewal in and develop, and wherein Water-borne modification is exactly one of dominant direction of formulations of pesticide development.Therefore, just arise at the historic moment, make it become novel form and be developed and applied with aqueous emulsion, the microemulsion of organic solvent in water section or the replacing whole missible oil.
Do not see at present the relevant report of the composite product of triaguron and chlopyrifos as yet.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of efficient, low-residual, low toxicity, environment compatibility, has synergistic function, the Pesticidal combination that the active ingredient that cost is low is made up of triaguron and chlopyrifos.

Practice example one
Triaguron and the test of chlorpyrifos mixture pairing oranges and tangerines aphid Toxicity Determination
This EE designs 5 concentration with Pesticidal combination of the present invention respectively by active constituent content and handles in Shandong Agricultural University, adopts and soaks the worm leaf dipping method; Aphid is immersed 5s in the soup together with the oranges and tangerines blade, takes out the back and sop up the unnecessary soup on the leaf margin with blotting paper, reject have wing become aphid, if aphid; Only keep aptery one-tenth aphid; Put it into the raising of preserving moisture in the culture dish, put into 25 ℃ illumination box then, inspection survival borer population after 48 hours; Every concentration is handled repetition 3 times, the every repetition with 150 of examination worms.Calculate the insect population rate that goes down, proofread and correct the insect population rate that goes down, try to achieve virulence regression equation and calculate LC
50
The different proportionings with chlopyrifos of table 1 triaguron are used the toxicity test to the oranges and tangerines aphid with
Can know triaguron and chlorpyrifos mixture toxicity test by table 1 to the oranges and tangerines aphid; Removing proportioning is that 1: 10 o'clock co-toxicity coefficient is 114.04, and other proportionings show synergistic function all greater than 120; Triaguron wherein: chlopyrifos=co-toxicity coefficient was 159.82 in 1: 3 o'clock, and synergistic effect is particularly outstanding.
Practice example two
Handle the report of the chemical control rice hoppers test of pesticide effectiveness
Table 2 is handled chemical control rice hoppers field control effectiveness test
Can know that by table 2 triaguron and chlorpyrifos mixture have good control efficiency to rice hoppers; Preventive effect is superior to single agent preventive effect; And have quick-acting and lasting effect preferably; In this experimental drug scope, to rice safety, preparation of the present invention has good preventive effect to rice leaf roller, striped rice borer, paddy stem borer.
Practice example three
Handle the report of the chemical control oranges and tangerines aphid test of pesticide effectiveness
Table 3 is handled chemical control oranges and tangerines aphid field control effectiveness test
Find out that by table 3 triaguron of the present invention and chlorpyrifos mixture composition have the better prevention effect to the oranges and tangerines aphid, control efficiency is that control efficiency is 83.5%～90.7% after 85.5%～93.7%, 15 days after 7 days, is superior to contrasting pharmacy control efficacy.Simultaneously, this medicament dosage is little, and to oranges and tangerines safety, Pesticidal combination of the present invention also has good control efficiency to oranges and tangerines aleyrodid, acarid in this test medicine scope.
In sum, behind triaguron and the chlorpyrifos mixture in practical application the single agent than single-activity composition show excellent more insecticidal activity, enlarged insecticidal spectrum; Control to homoptera pest has obvious role in synergism; One medicine is controlled more, has reduced the recruitment cost, has improved production efficiency; And to crop safety, environmental pollution is little.So R&D and promotion of the present invention has crucial meaning.
