Description
Technical field
The present invention relates to the agriculture chemical compounding technical field, being specifically related to a kind of is two yuan of Pesticidal combinations that are mixed of active ingredient with thiophene insect amide and benzoyl urea compound.
Background technology
The thiophene insect amide, test code number JS9117, it is the novel adjacent heterocycle benzamide compound that the Jiangsu Pesticide Research Institute Co., Ltd is found in initiative in 2009, chemical name is 3-bromo-N-{4-chloro-2-methyl-6-[2-(5-amino-1,3, the 4-thiadiazoles)] phenyl-1-(3-chloropyridine-2-yl)-1H-pyrazoles-5-formamide
[1], lepidopterous insects such as diamond-back moth, beet armyworm, prodenia litura, cotton bollworm, striped rice borer are had high activity.Structural formula is:
The Acarus tritici urea, chemical name: RS)-and 1-[2,5-two chloro-4-(1,1,2,3,3,3-hexafluoro propoxyl group) phenyl]-3-(2, the 6-difluoro benzoyl) urea, molecular formula: C
17H
8C
12F
8N
2O
3, act on insect larvae, stop the decortication process and kill off the insect pests, especially food leaf caterpillars such as fruit tree there is outstanding preventive effect, thrips, rust mite, trialeurodes vaporariorum there are unique mechanism of killing, be suitable for control to pyrethroid and organophosphorous pesticide generation resistant insect.
Butyl ether urea (Diafenthiuron), C
23H
32N
2OS is a kind of novel Thiourea efficient insecticide, miticide, have tag, stomach toxicity, interior suction and fumigation action, low toxicity, but to fish, the high poison of honeybee.Under ultraviolet light, change material into, have stronger activity having produced serious drug-fast insect on the vegetables with insecticidal activity.Can prevent and treat aphid, aleyrodid, leafhopper, noctuidae pests and evil mite on various crop and the ornamental plants.
Fluorine bell urea, 1-[3,5-two chloro-4-(1,1; 2,2-tetrafluoro ethyoxyl) phenyl]-3-(2, the 6-difluoro benzoyl) urea, this product belongs to the benzoyl urea insecticide; be chitin synthesis inhibitor, have very high desinsection and ovicidal activity, and quick-acting, especially prevent and treat cotton bollworm.Be used for cotton, potato and fruit tree and prevent and treat multiple coleoptera, diptera, Homoptera insect.
The fluorine uride has the compound of stomach toxicity and action of contace poison simultaneously concurrently, has the insecticidal activity of wide spectrum, and is not only effective to lepidoptera pest, and plant hopper and other class pests are also had activity; Activity to sea ash wing moth 3 instar larvaes at night is suitable with UC 62644 10, is 10 times of Teflubenzuron 11, and B.tabaci ovum and larva are all had good active.
The grand pyridine tick urine that has another name called of pyrrole worm; the fluorine pearl is grand; fluorine pyridine tick urine; chemical name: 1-[4-chloro-3-(3-chloro-5-trifluoromethyl)-2-pyridine oxygen base phenyl)]-3-[2; the 6-difluoro benzoyl] urea; white is to the off-white powder crystallization, and the pyrrole worm is grand to be a kind of parasite growth regulator, and multiple animal body epizoas such as ox, sheep, rabbit are had good killing effect.
Use above medicament separately, exist cost bigger, shortcomings such as quick-acting or lasting effect difference.Good in order to develop quick-acting and lasting effect, lower-cost agricultural chemicals, we filter out thiophene insect amide and benzoyl urea compound and carry out composite on the basis of lab screening and field trial, have obvious synergistic effect, and do not find relevant report so far.
Summary of the invention
Based on above situation, the present invention proposes a kind of new insecticides: said composition contains two kinds of active components of A, B, and component A is selected from the thiophene insect amide, B component is selected from that the pyrrole worm is grand, in the butyl ether urea, fluorine bell urea, fluorine uride, Acarus tritici urea arbitrarily it
Describedly contain that A thiophene insect amide and B benzoyl urea compound pyrrole worm are grand, one or two yuan of any composite Pesticidal combination in the butyl ether urea, fluorine bell urea, fluorine uride, Acarus tritici urea, the percentage by weight of effective active composition A and B is 1～80: 80～1.
Describedly contain that A thiophene insect amide and B benzoyl urea compound pyrrole worm are grand, one or two yuan of any composite Pesticidal combination in the butyl ether urea, fluorine bell urea, fluorine uride, Acarus tritici urea, the percentage by weight of effective active composition A and B is preferably 1～40: 40～1.
It is one of key character of the present invention that two kinds of active components of A, B are re-dubbed new compositions according to a certain percentage, and another feature is that described to contain the formulation that thiophene insect amide and the composite Pesticidal combination of benzoyl urea compound can be made into be aqueous emulsion, microemulsion, missible oil, suspending agent, wetting powder, water dispersible granules.
Describedly contain that thiophene insect amide and benzoyl urea compound pyrrole worm are grand, one or two yuan of any composite Pesticidal combination in the butyl ether urea, fluorine bell urea, fluorine uride, Acarus tritici urea, the gross mass content of two kinds of active components of A, B in preparation is 1%-90%, preferred 5%-50%; All the other are usual auxiliaries in the agricultural chemicals.
Pesticidal combination of the present invention has obvious synergistic effect, can reduce effective ingredient consumption, reduce cost, delay the generation of pest resistance to insecticide, effectively reduce environmental pollution and residue of pesticide, preventive effect is remarkable aspect control rice leaf roller, diamond-back moth, prodenia litura, cotton bollworm or Homopteras such as beet armyworm, thrips, thrips insect.

50, and press the abundant method of Sun Yun and calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (with the thiophene insect amide is the standard medicament, and its toxicity index is 100):
The LC of toxicity index (the TI)=thiophene insect amide of fluorine bell urea
50The LC of/fluorine bell urea
50* 100
The LC of actual toxicity index (ATI)=thiophene insect amide of M
50The LC of/M
50* 100
The TI of the TI of theoretical toxicity index (TTI)=thiophene insect amide of M * P thiophene insect amide+fluorine bell urea * P fluorine bell urea
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In the formula:
M is a fluorine bell urea and the mixture of the different proportionings of thiophene insect amide
P fluorine bell urea is fluorine bell urea shared ratio in mixture
P thiophene insect amide is thiophene insect amide shared ratio in mixture
