Compared with a single dosage, the quick acting effect and the persistence of the insecticidal composition are better, and the utilization dosage and the drug cost of pesticides are reduced; and comprehensive management of environmental protection and agricultural destructive insects is facilitated.
Description
[technical field]
The invention belongs to technical field of pesticide.More particularly it relates to an the Pesticidal combination containing sulfur insect amide and fenvalerate, further relate to the purposes of described Pesticidal combination.
[background technology]
Agricultural production practice usually faces the phenomenon that on a kind of crop, various pests mixing occurs; if in Oryza sativa L. while there is planthopper harm; being often associated with mixing and rice leaf roller, striped rice borer, yellow rice borer harm occur, vegetable also often mixes the harm such as trialeurodes vaporariorum, aphid and diamondback moth, Prodenia litura, beet armyworm occur.For this, people often repeatedly dispenser can be only achieved and prevent and treat various pests.Therefore on producing, it is badly in need of a dispenser can prevent and treat the Pesticidal products of various pests simultaneously, to reduce agricultural cost.
Striped rice borer, rice leaf roller and pink rice borer are had efficient insecticide effect by sulfur insect amide insecticides, and CN103109816A discloses a kind of novel O-formammidotiazol-benzamide compounds, in its general structure I, and R1Selected from Cl or Br；R2Selected from methyl, isopropyl or pi-allyl；R3Selected from H or Cl.They have the insecticidal activity of excellence, can be used for the preventing and treating of agricultural or forestry pest.CN103130770A discloses a kind of 3,5-dihalo sulfur insect amide insecticides, in its general structure I, and R1Selected from Cl or Br；R2Selected from methyl, isopropyl or pi-allyl；R3Selected from H or Cl.They can be used for the preventing and treating of agricultural or forestry pest.Sulfur insect amide is a kind of bisamide insecticides, has low toxicity, and the lasting period is long, to crop safety, to Fish low toxicity, the feature that eco-environmental impact is little.The insects such as beet armyworm, diamondback moth, Pieris rapae, small heart-eating peach worm, aphid or bollworm are had good prevention effect by it.
Fenvalerate is a kind of chrysanthemum ester insecticide, has and tags and stomach poison function, and action of contace poison is rapid, knocks down power strong, it does not have stifling and systemic action, and some insects have repellent action, lasting period length 7～12 days in higher concentrations.Its insecticidal spectrum is wide, to various pests poison such as Homoptera, Orthoptera, Semipteras effectively.
When sulfur insect amide and fenvalerate are used alone, drug cost is higher, limits its popularization and application to a certain extent, and is used alone for a long time and easily causes pest resistance degree and be continuously increased.The mixture of different pesticide species, is the common methods of preventing and treating agricultural resistant insect.Screened by formulation of pesticide, filter out rational formula, actual prevention effect can be effectively improved, reduce dosage, reduce cost, delay the generation of pest resistance to insecticide, extend the service life of medicament, be the important means of integrated pest management.
These prior aries there is also some technological deficiencies, is not met by current agricultural production needs, therefore also needs to the Efficient insecticidal composition that exploitation is new, and this is extremely important for advancing agricultural large-scale development.

Two, bioactive mensuration
In order to further appreciate that the virulence of sulfur insect amide and fenvalerate compositions, carry out a large amount of formulation screening test.
Pesticidal combination biological activity determination of the present invention is as follows:
Evaluate SOP (insecticide volume) according to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.7-2006) and initiative pesticide bioactivity, adopt infusion process to measure single dose LC50With mixture LC50, following formula calculate and obtain co-toxicity coefficient:
Toxicity index × the A of theoretical mixed toxicity index (TTI)=A content (%) in using with
Toxicity index × the B of+B content (%) in using with
When co-toxicity coefficient is more than 120, it was shown that this mixture has potentiation；And co-toxicity coefficient less than 80 time, it was shown that this mixture has antagonism；And co-toxicity coefficient more than 80 less than 120 time, it was shown that this mixture has summation action.
The results are shown in Table 1 for the Pesticidal combination biological activity determination being made up of sulfur insect amide and fenvalerate.
