Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains second worm nitrile.
Background technology
Second worm nitrile (ethiprole), inferior sulphur (sulphur) acyl group of chemical name: 5-amino-1-(2,6-, two chloro-p-trifluoromethyl phenyls)-4-ethyl pyrazoles-3-itrile group, chemical molecular formula: C

4OS.Second worm nitrile is the novel pyrazole insecticides, and insecticidal spectrum is wide.Disturb chloride channel by γ-An Jidingsuan (GABA), thereby destroy central nervous system (CNS) normal activity insect is caused death.This medicine is tightr to the white clothing constraint comparison vertebrate of insect GABA chloride channel.Thereby provide very high selection toxicity.Its mechanism of action is different from main insecticide families such as pyrethroid, organic phosphor, carbamate, does not almost produce the chance of interactivity with the existing insecticide of majority.Therefore, it is the desirable reserve kind of resistance management, can be with the mixed pesticide of other chemical family, be used alternatingly.
Dimehypo (bisultap), chemical name: 2-N, N dimethylamine base-1, two (the thiosulfonic acid sodium base) propane of 3-, be a kind of never poison, insect contact and get the food medicament after show that blunt, slow in action, as to lose infringement crop ability, stasi, polypide are softening, paralysis, until death.Dimehypo has very strong systemic action, can be absorbed and conduction by the leaf of crop, root etc.
Indenes worm prestige (indoxacarb), chemical name: 7-chloro-2,3,4a, 5-tetrahydrochysene-2-[methoxycarbonyl (4-Trifluoromethoxyphen-l) carbamoyl] indeno [1,2-e] [1,3,4-] oxadiazines-4a-carboxylate methyl ester, chemical molecular formula: C

7Indenes worm prestige mainly is the sodium channel in the blocking-up insect nerve cell, causes target pest to coordinate poor, paralysis, and is final dead.Medicament enters polypide by tagging and ingesting, and the behavior of insect changes rapidly, causes insect to stop rapidly ingesting, thus fabulous protection the target crop.Test shows with other insecticide not have cross resistance.
Thiocyclam (thiocyclam-hydrogenoxalate), chemical name: N, N-dimethyl-1,2,3-trithio heterocycle oneself-5-amine and oxalate thereof, chemical molecular formula: C

3Be sandworm toxin insecticide, have and tag and stomach poison function that certain interior suction and fumigation action are also arranged, and can kill ovum.Toxic effect to insect is slower, and poisoning the lighter can be brought back to life sometimes.It disappears in plant corpus comparatively fast, and the longevity of residure is shorter, and the residual quantity during results in the crop seldom.Thiocyclam is effective to Lepidoptera, coleoptera, homoptera pest, can be used for preventing and treating the various pests on paddy rice, corn, beet, fruit tree, the vegetables, but big to the toxicity of silkworm.
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.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 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.Test discovery in a large number through the inventor, after second worm nitrile and dimehypo, indenes worm prestige, thiocyclam were composite, synergistic effect was remarkable, and Environmental compatibility is fabulous, has greatly reduced the agricultural chemicals dosage.

Above-described embodiment 25, embodiment 26 described active component B are a kind of arbitrarily in indenes worm prestige, dimehypo, the thiocyclam, and the weight ratio of second worm nitrile and active component B is any one ratio between 1: 80～60: 1.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Earlier by Toxicity Determination, 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 standby 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 soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then for 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 considered as invalid test greater than 10%.Computing formula is as follows:
The insect corrected mortality is converted into probit value (y), and concentration for the treatment of (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 following (be standard medicament with second worm nitrile, its toxicity index is 100):
TI * the P of the theoretical toxicity index (TTI) of M=second worm nitrile
Second worm nitrileTI * P of+active component B
Active component B
In the formula: M is the mixture of different proportionings;
P
Active component BBe active component B shared ratio in composition;
P
Second worm nitrileBe second worm nitrile shared ratio in composition.
Annotate: active component B is a kind of arbitrarily in dimehypo, indenes worm prestige, the thiocyclam.
