Abstract
The invention relates to an insecticide compound containing hexaflumuron, which consists of effective components of hexaflumuron and fipronil, and can be made into such dosage forms as micro-emulsion, EC and suspo-emulsion. The weight percentage between the effective components of hexaflumuron and fipronil is hexaflumuron : fipronil is equal to (1 to 10) : (10 to 1); the effective components hexaflumuron and fipronil have obvious complementary and synergism action. If being used in controlling the pests in agriculture, the control effect of the invention is obviously better than a single agent of hexaflumuron and fipronil. The invention has the advantages of quick effect, long effective period and low usage cost. The control effect is free from temperature and the invention has an extremely obvious popularizing value.
Description
Technical field
The composition pesticide that this invention relates to is to be active ingredient with fluorine bell urea and fluorine worm nitrile, prevents and treats the insect on the agricultural.Especially beet armyworm there is special efficacy.
Background technology
Fluorine bell urea is a kind of efficient, low toxicity, the agent of low-residual New-type wide-spectrum insects, is used to prevent and treat agricultural and goes up important harmful mite such as tetranychid, Tetranychus cinnabarinus etc., to control report is also arranged this year such as diamond-back moth, cabbage caterpillar, beet armyworm, aleyrodid.
Fluorine worm nitrile is a kind of new type disinsection miticide, and being used to prevent and treat upward important insect of agricultural such as cabbage caterpillar, beet armyworm, prodenia litura, diamond-back moth etc. also has good control efficiency to striped rice borer common on the agricultural, Tetranychus urticae, Tetranychus cinnabarinus etc.
Beet armyworm is a kind of common insect, and the main harm brassicaceous vegetable is often caused crushing disaster.Especially in the zone, south, beet armyworm is annual takes place.In some serious zone, the Methomyl of the cypermethrin in conventional pesticide composition such as the pyrethroid, the malathion in the organic phosphor, carbamates etc., control efficiency is very poor separately.
Go up the insect that produces resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But, the development cost height of new active ingredient, the construction cycle is long, and all fast less than the speed of insect generation resistance forever.Other method is rotated etc. in the process of practical operation as crop allocation adjustment, different agricultural chemicals, is difficult to really play obvious effects.
The composition of different cultivars carries out composite, is control resistant insect and the very common way of evil mite.Heterogeneity is carried out composite, and according to the effect of practical application, judge certain composite be synergy, or straw anti-.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby delayed the generation of pest resistance to insecticide greatly, be the important means of integrated control insect, still nobody reported in the composite and application of fluorine bell urea and fluorine worm nitrile at present.
Summary of the invention
In order to prevent and treat the beet armyworm on the agricultural, I have carried out mutual composite synergy research with compositions such as fluorine bell urea, fluorine worm nitriles by door.The beet armyworm in field is adopted in test, is used for experiment after raising.Concrete grammar is: experimental pharmacy provides former medicine for producer, is mixed with the preparation that needs by my research and development department of company.The experiment worm be field beet armyworm pupa, the indoor feeding three generations, select the growth uniformity third-instar larvae, be placed on the blade of the beet of prohibiting soup, and unnecessary soup is removed in examination, and establishes the clear water blank, will have the blade that tries worm and be placed in the culture dish, every ware connects 20, every processing connects three wares, 8---10 concentration tonsure is set, the culture dish of handling, in the normal temperature incubator, cultivate and checked the survival borer population in 48 hours, calculate the insect population rate that goes down; Toxicity index; Numerical value such as co-toxicity coefficient.(the virulence result of different disposal gained such as following table)
| Handle | LC 50 | Co-toxicity coefficient |
| Fluorine bell urea 10+ fluorine worm nitrile 1 | 75.13 | 420.22 |
| Fluorine bell urea 8+ fluorine worm nitrile 3 | 50.12 | 550.72 |
| Handle | LC 50 | Co-toxicity coefficient |
| Fluorine bell urea 6+ fluorine worm nitrile 5 | 42.68 | 660.15 |
| Fluorine bell urea 4+ fluorine worm nitrile 7 | 30.35 | 750.14 |
| Fluorine bell urea 2+ fluorine worm nitrile 9 | 15.55 | 680.35 |
| Fluorine bell urea 1+ fluorine worm nitrile 10 | 18.31 | 630.56 |
| Fluorine bell urea | 72.62 | |
| Fluorine worm nitrile | 80.25 |
From top table, find out fluorine bell urea and Firponil compounded good synergistic effect arranged.
Embodiment
