Abstract
The invention provides a pesticidal composite for preventing sanitary pests like mosquitoes, flies, Blattella germanica and the like. The pesticidal composite contains chlorantraniliprole which serves as pesticidal active ingredient and piperonyl butoxide or octacide 264 which serves as synergist, and the amount of the piperonyl butoxide or octacide 264 is 1-20 times that of the chlorantraniliprole by weight. The pesticidal composite can be prepared to be pest-repellent incense coils, electrothermal mosquito mats, electrothermal liquid mosquito repellent and pest aerosol to be used where mosquitoes, flies, Blattella germanica and the like haunt so as to achieve the effects of preventing and killing the pests.
Description
Technical field
The invention provides a kind of Pesticidal combination of preventing and treating sanitary insect pests such as mosquito, fly, Groton bug, comprising Rynaxypyr as active insecticidal components, and as the Butacide or the Octacide 264 of synergist.
Background technology
Rynaxypyr, chemical name 3-bromo-N-[4-chloro-2-methyl-6-(amino-carbonyl phenyl)-1-3 chloro-2-pyridine]-1H-pyrazoles-5-carboxylic acid amides, be the ryania acceptor inhibitor insecticides that a new generation has unique effect mechanism.Calcium channel effect in the body of its directional jamming target pest causes that the internal calcium ion unrestrictedly discharges, and stops contraction of muscle, thereby makes insect stop to get food rapidly, muscular paralysis, vigor disappearance, paralysis occur, until thorough death.Just because of the mechanism of action of this uniqueness, Rynaxypyr all shows low toxicity to mammal, bird, fish and useful insect; Simultaneously there is not cross resistance with traditional organic phosphor, pyrethroid, anabasine insecticide.The Rynaxypyr insecticidal spectrum is very wide, has been used to prevent and treat pest such as mythimna separata (subtropics mythimna separata, meadow mythimna separata, yellow bar mythimna separata), cotton bollworm, cabbage caterpillar, maize borer, striped rice borer, paddy stem borer, pink rice borer, rice leaf roller.(WO2003015519,WO2005107468,WO2006108553,WO2007039080)
On the other hand, traditional health that is used for exists fish, honeybee, the highly toxic shortcoming of silkworm with the pyrethroid insecticides of desinsection product always, and growth along with service time, mosquitos and flies has produced pesticide resistance (Gao Xiwu etc. in various degree to some pyrethroid products, Chinese media biology and control magazine, 2004,15 (2), 105).
Thus, the present invention uses Rynaxypyr to be used to prepare hygienic insecticide as active ingredient, not only can overcome beneficial organism high toxicity shortcoming, also can not produce cross resistance.In the screening formula process, finding can significantly increase the insecticidal effect of Rynaxypyr by adding Butacide or Octacide 264, thereby greatly reduces drug cost.Butacide or Octacide 264 are preferably 2-5 doubly by weight for the 1-20 of Rynaxypyr doubly is advisable.With this Rynaxypyr that comprises as active insecticidal components, and be used to prepare disc type insecticidal incense, electric mosquito repellent tablet, electric liquid device, insect aerosol as the Butacide of synergist or the Pesticidal combination of Octacide 264, it is stable to have obtained a collection of volatilization, drug effect is good, long-lasting hygienic biocide product.
Summary of the invention
The invention provides a kind of Pesticidal combination of preventing and treating sanitary insect pests such as mosquito, fly, Groton bug, comprising Rynaxypyr as active insecticidal components, and as the Butacide or the Octacide 264 of synergist, the amount of Butacide or Octacide 264 be by mass Rynaxypyr 1-20 doubly.Use this Pesticidal combination to prepare disc type insecticidal incense, electric mosquito repellent tablet, electric liquid device and insect aerosol product, be used for sanitary insect pests such as mosquito, fly, Groton bug and haunt the effect of reach control, killing.
Below the application in preparation various forms insecticide is described in detail to this Pesticidal combination:
(1) preparation disc type insecticidal incense
Described disc type insecticidal incense is mixed with Pesticidal combination to join behind the liquid form and makes in the base material, and wherein Rynaxypyr content is 0.005-2.0w/w%.
