Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of composition pesticide on the control crop pest that contains second mite azoles.
Background technology
Second mite azoles (etoxazole) molecular formula: C
21H
23F
2NO
2, second mite azoles belongs to 2, and 4-diphenyl-oxazole derivatives quasi-compound is a kind of selectivity miticide.Mainly be the process of casting off a skin that suppresses the mite class, thereby mite is all had excellent tagging property from ovum, larva to the pupa different phase.But the control efficiency to adult is not fine.The mite class that Hexythiazox has been produced resistance has good control efficiency.
Biphenthrin (bifenthrin) chemical name: (1R, S)-cis (Z) 2,2-dimethyl-3-(2-chloro-3,3,3-three fluoro-1-acrylic) cyclopropane-carboxylic acid-2-methyl-3-phenyl benzyl ester, molecular formula: C
23H
22ClF
3O
2, Biphenthrin belongs to the pyrethroid Insecticidal and acaricidal agent.Have tag, stomach poison function, do not inhale in not having, fumigation action, insecticidal spectrum is wide, effect rapidly.In soil, do not move, safer to environment, the longevity of residure is longer.Be applicable to and prevent and treat insects such as lepidopterous larvae, aleyrodid, aphid, leaf miner, leafhopper, tetranychid, evil mite on the crops such as cotton, fruit tree, vegetables, tealeaves.Be used for worm, when mite is concurrent, province's medicine saves time.
Buprofezin (buprofezin) chemical name: 2-Te-Ding imido grpup-3-isopropyl-5-phenyl-3,4,5,6-tetrahydrochysene-2H-1,3,5-thiadiazine-4-ketone, molecular formula: C
16H
23N
3OS, Buprofezin are a kind of new selective insecticides that insect growth is grown that suppresses, and action of contace poison is strong, and stomach poison function is also arranged.Mechanism of action is synthetic and disturb metabolism for suppressing insect chitin, causes nymph cast off a skin deformity or wing deformity and slowly dead.Just can find out effect in 3-7 days after the general dispenser, adult not had direct killing power, but can shorten its life-span, reduce egg laying amount, and output be mostly addle-egg, even the larva hatching is also very fast dead.Double wing purpose plant hopper, leafhopper, aleyrodid and scale insect class pest have good control efficiency, and the drug effect phase reached more than 30 days.Safer to natural enemy, comprehensive effect is good.
Yet in the real process of agricultural production, the problem that pest control is easy to generate most is the generation of pest resistance to insecticide.Important insect on the agricultural, because its breeding cycle is short, breeding amount is big, and mobility is little, and the selfing degree is high, is easy to generate resistance especially.
The different cultivars composition carries out composite, is the very common method of control 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 all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find producing good synergistic effect behind second mite azoles and Biphenthrin, the buprofezin compound, and still unexposed about the relevant report of second mite azoles and Biphenthrin, buprofezin compound.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker subsequent use respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 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 the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
The insect corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with second mite azoles is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of the theoretical toxicity index (TTI) of M=second mite azoles
Second mite azolesTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P
Effective active composition BBe effective active composition B shared ratio in composition
P
Second mite azolesBe second mite azoles shared ratio in composition
A is selected from second mite azoles;
B is selected from following any one compound: a kind of in Biphenthrin, the Buprofezin.
