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 emamectin-benzoate, 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。
Emamectin-benzoate (epimethylamino-4 "-deoxyavermectinbenzoate (b1aandb1b)) it is the new and effective semisynthetic antibiotics insecticide of one starting synthesis from fermented product AVERMECTIN B1; it has ultra high efficiency; low toxicity (preparation is closely nontoxic); noresidue; the nuisanceless feature waiting biological pesticide; its insecticidal activity improves 1-3 the order of magnitude compared with avilamycin, and the activity of lepidopteran insect larvae and other many insects and demodicid mite class is high。Its model of action, based on stomach toxicity, has action of contace poison concurrently, and its insecticidal mechanism is to hinder pest movements neural。
Emamectin-benzoate, due to life-time service, has created certain resistance。At present by the pesticide of different mechanism of action is carried out composite, it it is the common methods of preventing and treating agricultural resistant insect。Screened by formulation of pesticide, filter out rational formula, prevention effect can be effectively improved, reduce dosage, delay the generation of pest resistance to insecticide, extend the service life of medicament, be the important means of integrated pest management。
But, there are some technological deficiencies in these prior aries, is not met by current agricultural production needs, therefore also needs to the Pesticidal combination efficiently preventing and treating rice pest that exploitation is new, and this is extremely important for advancing agricultural large-scale development。
