The present invention relates to a kind of Pesticidal combination containing sulphur insect amide and pleocidin, sulphur insect amide is with pleocidin according to weight ratio 1~30：1~60 mixture has apparent synergistic effect.The Pesticidal combination of the present invention is suitable for preventing crops beet armyworm, diamondback moth, cabbage caterpillar, thrips, small heart-eating peach worm, aphid, rice leaf roller or bollworm pest with insecticide.It is superior to single dose in terms of quick-acting and lasting effect, and reduces the dosage and drug cost of pesticide, is conducive to environmental protection and the comprehensive treatment of agricultural pests.
Description
【Technical field】
The invention belongs to technical field of pesticide.More particularly it relates to which a kind of containing sulphur insect amide and pleocidin
Pesticidal combination, further relate to the purposes of the Pesticidal combination.
【Background technology】
It usually faces various pests mixing on a kind of crop in agricultural production practice to occur, if rice is in generation rice
While plant hopper endangers, it is often associated with mixing and rice leaf roller, striped rice borer, yellow rice borer harm occurs, vegetables also often send out by mixing
The harm such as raw trialeurodes vaporariorum, aphid and diamondback moth, prodenia litura, beet armyworm.For this purpose, people often want multiple dispenser can be only achieved
Prevent various pests.Therefore the Pesticidal products of various pests can be prevented simultaneously by being badly in need of a dispenser in production, to reduce agriculture
Use cost.
Sulphur insect amide insecticides have efficient insecticide effect, CN to striped rice borer, rice leaf roller and pink rice borer
103109816A discloses a kind of novel O-formammidotiazol-benzamide compounds, in general structure I, R1Selected from Cl or
Br；R2Selected from methyl, isopropyl or allyl；R3Selected from H or Cl.They have excellent insecticidal activity, can be used for agricultural or woods
The prevention of industry pest.CN 103130770A disclose one kind 3,5- dihalo sulphur insect amide insecticides, in general structure I,
R1Selected from Cl or Br；R2Selected from methyl, isopropyl or allyl；R3Selected from H or Cl.They can be used for agriculture or forestry pest
Prevention.Sulphur insect amide is a kind of bisamide insecticides, has low toxicity, and the lasting period is long, right to fish low toxicity to crop safety
The small feature of eco-environmental impact.It is to pests such as beet armyworm, diamondback moth, cabbage caterpillar, thrips, rice leaf roller, bollworms
There is good control effect.
Pleocidin is a kind of macrolides biological pesticide, exists to insect and quickly tags and toxicity of ingesting, it has
The distinctive poisoning symptom of never poison, its mechanism of action are the nervous systems by stimulating insect, increase its constitutive activity, lead
It causes non-functional flesh to shrink, failure, and with trembling and benumbing, shows that nAChR (nChR) is continued
Activation causes acetylcholine (Ach) extended release to be reacted.Pleocidin also acts on mono- aminobutyric acids of γ (GAGB) receptor simultaneously,
The function of changing GABA gate chloride channels, further promotes the raising of its insecticidal activity.
Drug cost is higher when sulphur insect amide and pleocidin are used alone, and limits its popularization to a certain extent and answers
With, and long-term exclusive use be easy to cause pest resistance degree and is continuously increased.
But there is also some technological deficiencies for these prior arts, are not met by current agricultural production needs, therefore also
It needs to develop new Efficient insecticidal composition, this is for promoting agriculture large-scale development to be extremely important.

Obtain co-toxicity coefficient：
Contents (%) of the toxicity index × A of mixed toxicity index (the TTI)=A of theory in mixed
Contents (%) of the toxicity index × B of+B in mixed
When co-toxicity coefficient is more than 120, show that this mixture has synergistic effect；And co-toxicity coefficient be less than 80 when, show
This mixture has antagonism；And co-toxicity coefficient be more than 80 less than 120 when, show this mixture have summation action.
The results are shown in Table 1 for the Pesticidal combination biological activity determination being made of sulphur insect amide and pleocidin.
