Description

A kind of composition pesticide
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of composition pesticide on crop pest.
Technical background
Fluacrypyrim (Fluacrypyrim) chemical name: methyl (E)-2-{ α-[2-isopropoxy-6-(trifluoromethyl) pyrimidine-4-phenoxy group]-0-tolyl }-3-methoxy acrylate, molecular formula: C 20h 21f 3n 2o 5.Fluacrypyrim is first methoxy acrylic miticide.Have and well tag and stomach poison function, to each feature of evil mite, if comprise ovum mite, one-tenth mite all effectively, and quick-acting is good, and the lasting period reaches more than 30 days.
Tebufenpyrad (Tebufenpyrad) chemical name: N-(4-tertiary butyl benzyl) the chloro-3-ethyl of-4--1-methylpyrazole-5-base formamide, molecular formula: C 18h 24cLN 3o.Belong to amide-type miticide.To various mite class and Semiptera, homoptera pest, there is tall and erect effect, and the dawn all to have immediate effect each vegetative period to mite class and efficiently, the lasting period is long.Without interior absorption, but there is osmotically active, have splendid selectivity to target crop.
Propargite (Propargite) chemical name: 2-(4-tert-butyl benzene oxy) cyclohexyl Propargyl sulfite, molecular formula: C 19h 26o 4s.Low toxicity broad spectrum activity organosulfur acaricide, has and tags and stomach poison function, without interior suction and infiltration conduction, if effective to one-tenth mite mite, the weak effect of ovicidal, this medicine drug effect under temperature more than 20 DEG C conditions can improve, but fall progressively with low temperature below 20 DEG C, propargite can be used for preventing and treating cotton, vegetables, apple, citrus, tea, the harmful mite of the various crop such as flowers, safer to most natural enemy, but want strict controlled concentration when using on tender little crop, too high easy generation poisoning.
Fenazaquin (Fenazaquin) chemical name: 4-spy-butyl benzene ethyl quinazoline-4-base ether, molecular formula: C 20h 22n 2o.It belongs to quinolines miticide, and by action of contace poison in the mitochondria of insect cell and chromosome set I, there is good control efficiency at the abutment occupying ubiquinone to mandarin tree, apple tree two spotted spider mite, and the lasting period is long, to natural enemies security.
Halfenprox (Halfenprox) chemical name: 2-(4-bromine difluoro-methoxy phenyl)-2-methyl-propyl-3-phenoxy benzyl ether, belong to non-pyrethroid medicament, but its space structure and pyrethroid there is similarity.This product is a kind of broad spectrum activity, if to young mite mite with to become mite down effect good, the hatching of ovum can also be suppressed, to evil mite resistant strain and sensitive strain all effective, under normal using dosage to fruit tree without poisoning.
But in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Through inventor's research, find fluacrypyrim and tebufenpyrad, propargite, fenazaquin, halfenprox is composite after can produce good synergistic effect, and not yet open about the relevant report that fluacrypyrim and tebufenpyrad, propargite, fenazaquin, halfenprox are composite.

The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, on this basis, then carry out field trial.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, is placed in beaker respectively for subsequent use.Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid configured, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 50, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC 50value.If contrast lethality is greater than 10%, be then considered as invalid test.Computing formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value to (x), draws virulence regression equation, and calculate the value of often kind of medicament thus with method of least squares.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (take fluacrypyrim as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=fluacrypyrim of M fluacrypyrimtI × the P of+active component B effective active composition B
In formula: M is the mixture of different ratio
P effective active composition Bfor the ratio that effective active composition B is shared in the composition
P fluacrypyrimfor the ratio that fluacrypyrim is shared in the composition
B is selected from the one in tebufenpyrad, propargite, fenazaquin, halfenprox.
