Description
Technical field
The invention belongs to technical field of pesticide, specifically disclose a kind of composition pesticide containing pyridine quinazoline, contain
Active ingredient A and B, wherein A is selected from pyridine quinazoline, and B is in dinotefuran, Diacloden, Flupyrimin, Ivermectin HCL
It is a kind of.
Technical background
Pyridine quinazoline (pyrifluquinazon) be it is known, belong to novel quinazoline quinoline insecticides, the mechanism of action is
Pest is prevented to feed, until pest is slowly died of hunger.It is mainly used for preventing and treating Phytophthira, aleyrodid on the crops such as vegetables, fruit tree and tealeaves
The suckings mouthpart insects such as class, shell insects, leafhopper class, thrips class, can be significantly reduced the propagation of viral vectors.The compound
Can with complete penetration blade face, to below blade face the pest of predation and perch also can reach the purposes of effective prevention and control.CN
1823055 B disclose pyridine quinazoline, preparation method and its purposes as insecticide, and 105454277 A of CN discloses pyrrole
The combination of pyridine quinazoline and clothianidin.
Dinotefuran (dinotefuran) is known, is developed earliest by Mitsui chemical company, is listed in 2002
Third generation nicotinic insecticide.The medicament insecticidal spectrum is wide, has brilliant interior suction osmosis, and i.e. aobvious in very low dosage
Very high insecticidal activity is shown.The medicament is fool proof to mammal, birds and aquatile, to crop without phytotoxicity, to water
Homoptera, Lepidoptera on numerous crops such as rice, fruit tree, vegetables, Diptera pest have efficiently.
Diacloden (Thiamethoxam) is a kind of known, second generation nicotinoids high-efficiency low-toxicity desinsection of brand new
Agent has stomach toxicity to pest, tags and systemic activity, is used for foliar spray and soil root irrigation.It is interior rapidly after being administered
It inhales, and is transmitted to each position of plant, have good preventive effect to sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc..
Faenum graecum (Classification system：Trigonella foenum-graLCum L.) it is pulse family Trigonella plant Hu Luba
Habit claim, also make fenugreek, annual herb plant.Faenum graecum seed powder (FEN 560) is that the seed of faenum graecum maturation is ground into
Powder, can be used as insecticide.
Flupyrimin is known, is to be stepped in Japanese publication by Meiji Seika Kaisba in the trendy insecticide of Japan's research and development
Note, in Japan and progress market exploitation overseas.Flupyrimin can effectively prevent the primary pest in paddy field, such as planthopper
And snout moth's larva, moreover it is possible to which there are the Populations of resistant insect to existing pesticide for control.In addition, rarely having at present harmless to Pollinating Insect
Pesticide, and Flupyrimin is lower to the toxicity of honeybee, is a ideal insecticide.
The mechanism of action of Ivermectin HCL (Ivermectin) is mainly and in no spinal animals nerve cell and muscle cell
Glutamic acid is that the high-affinity of the chloride channel of valve combines, and the increase so as to cause cell membrane to chloride ion permeability is drawn
Nerve cell or muscle cell hyperpolarization being played, making pest paralysis or dead, the snout moth's larva of rice, vegetables are small agriculturally can be used for preventing and treating
The agricultural pests such as diamond-back moth, fruit tree mites.
Application chemical agent is one of most effective chemical means of prevention and treatment plant pathogeny line insect disease；With not cross resistance
Novel pesticide is come to prevent and treat plant pathogeny line insect disease be a good solution；But according to PhillipsMcDougall company
Research, compared to 2005-2008 years, between 2010-2014 years, discovery, 1 pesticide activity component of exploitation and registration it is flat
30,000,000 dollars of increased costs are researched and developed, 11.7% are increased in other words, up to 2.86 hundred million dollars.And in 2005-2008 years
Between, the average unit cost of agricultural chemicals research and development is 2.56 hundred million dollars, increases 39% compared with 2000；Average research and development cost in 2000 is
1.84 hundred million dollars, 21% is increased compared with nineteen ninety-five, while the development cycle is 5-10, is difficult the upper plant pathogeny line insect caught up with generation
The speed of drug resistance；Other methods such as crop structure adjustment, different pesticide rotations etc., in the actual operation process, have been difficult
To apparent effect.
Exploitation new product pesticide price is expensive, the period is long, and in contrast, it develops and studies efficient, less toxic, low-residual answer
And have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.

Specific embodiment
It is raw to survey embodiment
Test method reference《People's Republic of China (PRC) agricultural industry criteria NY/T1154.14-2008》, using leaf dipping method：
Win fresh tomato blade be placed in the medical fluid diluted impregnate 10s after take out, be placed on interior and dry, be then placed on diameter
In the culture dish of 9cm, each culture dish puts 1 tomato leaf.Tomato Bemisia tabaci 2 age nymph is gently chosen in culture dish, every ware
There are nymph 30, is culture dish sealing with preservative film, pricks several apertures on preservative film in favor of ventilative.Then setting temperature is
21 DEG C, raise in the incubator of photoperiod 16h: 8h (L: D), clear water control, each concentration is repeated 3 times.After 48 hours, double
Mesh test under microscope death condition (gently touches tomato Bemisia tabaci Nymph with dissecting needle, the motionless person of body is death).Generally
6 concentration gradients are arranged in each processing.Virulence equation and lethal concentration of 50 LC 50 are calculated with least square method, is counted according to Sun Yunpei
Calculate the toxicity index and mixed co-toxicity coefficient (CTC value) of medicament.
According to Sun Yunpei's Method, the synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are association
Same antagonism, 80 < CTC < 120 are joint action of antagonism, and CTC >=120 are synergistic function.Survey toxicity index
(ATI)=(LC of standard agent50The LC of/reagent agent50)×100；
The virulence of the percentage composition+B medicament of A medicament refers in toxicity index × mixture of theoretical toxicity index TTI=A medicament
The percentage composition of B medicament in number × mixture；
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
