Description

The Pesticidal combination of a kind of brominated cyanogen insect amide and pyrethroid

Technical field

The invention belongs to technical field of pesticide, relate to the Pesticidal combination of a kind of brominated cyanogen insect amide and pyrethroid.

Background technology

Bromine cyanogen insect amide (cyantraniliprole), chemical name: hydroxyl 3-bromo-1-(3-chloro-2-pyridine radicals)-N-[4-cyano group-2-methyl-6-[(methylamino)] phenyl]-1H-pyrazoles-5-formamide, chemical molecular formula: C₁₉H₁₄BrClN₆O₂The bromine cyanogen insect amide is E.I.Du Pont Company's second generation ryania acceptor inhibitor insecticides that success is developed after the chlorine insect amide, cyanogen insect amide is to form by the various polar groups that change on the phenyl ring, have more efficient, applicable crops is more extensive, can effectively prevent and treat Lepidoptera, Semiptera and coleopteran pest.

Gamma cyhalothrin (Lambda-cyhalothrin), chemical name: 3-(2-chloro-3,3,3-trifluoro-propenyl)-2,2-dimethyl cyclopropane carboxylic acid alpha-cyano-3-phenoxybenzyl ester, chemical molecular formula: C₂₃H₁₉ClF₃NO₃, gamma cyhalothrin is trifluoro cyhalothrin, cyhalothrin again.Its drug effect characteristics suppress the conduction at insect neural axon position, insect are had the effect of walking quickly and keeping away, knocking down and killing, insecticidal spectrum is wide, and active higher, drug effect is rapid, spray the back resistance of rainwater washing against, but long-term the use easily produces resistance to it, insect and the evil mite of sucking mouth parts had certain preventive effect.

Ether chrysanthemum ester (etofenprox), chemical name: 2-(4-ethoxyl phenenyl)-2-methyl-propyl-3-benzyloxy phenoxy base ether, chemical molecular formula: C₂₅H₂₈O₃, ether chrysanthemum ester is applicable on control paddy rice, vegetables, the cotton to Homoptera Delphacidae special efficacy, simultaneously various pests such as Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isoptera are also had good effect.Especially the control efficiency to rice hoppers is remarkable.Simultaneously also be that country forbids the appointed product of hypertoxic type agricultural chemicals after paddy rice is used.

Fenpropathrin (fenpropathrin), chemical name: alpha-cyano-3-phenoxy benzyl-2,2,3,3-tetramethyl-ring propane carbonyl acid ester, chemical molecular formula: C₂₂H₂₃NO₃, fenpropathrin is a kind of chrysanthemum ester insecticide, have tag, stomach toxicity and certain repellent action, absorption in not having, its maximum characteristics are to have concurrently multiple harmful mite is had good control efficiency.Can be used on the crops such as cotton, fruit tree, tea tree, vegetables insect and evil mites such as control Lepidoptera, Homoptera, Semiptera, diptera, coleoptera.

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 bromine cyanogen insect amide and gamma cyhalothrin, ether chrysanthemum ester, fenpropathrin were composite, synergistic effect was remarkable, and Environmental compatibility is fabulous, has greatly reduced the agricultural chemicals dosage.

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 LC₅₀Value.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 the bromine cyanogen insect amide, its toxicity index is 100):

TI * the P of theoretical toxicity index (TTI)=bromine cyanogen insect amide of M_{The bromine cyanogen insect amide}TI * P of+active component B_{Active component B}

In the formula: M is the mixture of different proportionings;

P_{Active component B}Be active component B shared ratio in composition;

P_{The bromine cyanogen insect amide}Be bromine cyanogen insect amide shared ratio in composition.

Annotate: active component B is a kind of arbitrarily in gamma cyhalothrin, ether chrysanthemum ester, the fenpropathrin.

Application Example two:

For trying insect: diamond-back moth.

Experimental scheme: effective lethal concentration scope of determining bromine cyanogen insect amide, the former medicine of gamma cyhalothrin and the two different proportioning mixture through preliminary experiment.
