Abstract
The invention discloses a metaflumizone-containing insecticide composition. A first active ingredient of the composition is metaflumizone; a second active ingredient is selected from cartap and bisultap of nereistoxin insecticides; and the weight ratio of the first active ingredient to the second active ingredient is 1:60. The insecticide composition can be prepared into formulations such as water dispersible granules, a suspending agent, wettable powder, microemulsion or emulsion in water. The insecticide composition can be used for controlling rice-stem borer and Cnaphalocrocis medinalis; the insecticide composition has reasonable components and a good insect-killing effect, is low in pesticide cost, is safe to crops, and meets the safety requirements of pesticide preparations; the activity and insect-killing effect of the composition are not equal to the simple superposition of the activities of the components, and the composition has a remarkable synergistic effect; and the resistance can be delayed.
Description
Technical field
The present invention relates to a kind of insecticides, particularly a kind of metaflumizone is as first active component, and the cartap of neires toxin, desinsection list, dimehypo or thiocyclam belong to technical field of compounded pesticide as the insecticides of second active component.
Background technology
Metaflumizone, english common name: metaflumizone, test code number BAS320I, chemical name (IUPAC): (E+Z)-2-[2-(4-cyanic acid benzene)-1-(3-trifluoromethylbenzene) ethylidene]-N-(4-trifluomethoxybenzene) hydrazine carbonyl oxamides; Molecular formula: C

2Metaflumizone is a kind of insecticide of brand-new mechanism of action, and on the acceptor attached to sodium-ion channel, it is current to hinder sodium ion, does not have cross resistance with the compound of chrysanthemum ester class or other kinds.This medicine mainly is to get food through insect to get into and stomach toxicity to take place in its body kill off the insect pests, and action of contace poison is less, no systemic action.This medicine all has the better prevention effect for target pest, the larva in each length of time, and this medicine gets into polypide behind the insect's food-taking, through the sodium-ion channel on the mechanism of action blocking-up insect neuron axon film of uniqueness; Make sodium ion can not pass through axolemma; And then suppress nerve impulse and make excessive the loosening of polypide, paralysis is behind the several hrs; Insect promptly stops to get food, and is dead in 1 ~ 3d.Laboratory research shows, mammal impassivity toxicity, Salmonella reversion test are negative; Lasting period is short in environment.The metaflumizone of selling in the market is the suspending agent of 240 grams per liters and 20% missible oil, is mainly used in the caste Lepidoptera and the coleoptera that chew and sting food.Professional insecticide as a kind of new mechanism; Metaflumizone in use exists the use cost height; The risk that resistance increases gradually, the defective that the lasting period is general, and rationally use with dissimilar nereistoxins; For fully effectively promoting metaflumizone, prolong its service life and have important function.
Cartap has another name called Padan, and group is red, english common name cartap, molecular formula C

3, be sandworm toxin insecticide, have and tag and stomach poison function, 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.
At present, be that the pesticidal preparations of effective ingredient is main with 240 grams per liter metaflumizone suspending agents with the metaflumizone, also have 20% metaflumizone missible oil, in actual use, quick-acting is good, but lasting effect is general, and use cost is high; Neires toxin is as domestic insecticide variety commonly used; Insecticidal effect and cost performance are the user all the time and accept; But resistance is rising year by year, and the inventor is unexpected to find the use that rationally is mixed of desinsection snout moth's larva, benthiocarb, dimehypo or thiocyclam with metaflumizone and neires toxin, has significant synergistic effect; Can reduce use cost, slow down the generation of pest resistance.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, significantly synergy, good disinsection effect, drug cost is low, the insecticides that contains metaflumizone that is difficult for developing immunity to drugs.

Embodiment
In order to prevent and treat the insects such as rice-stem borer in the agricultural production, the inventor has carried out mutual composite synergy research with compositions such as metaflumizone, cartap desinsection list, dimehypo and thiocyclams.It is tested object that rice-stem borer is adopted in test, and concrete grammar is:
The rice-stem borer formal name used at school (
Chilo supperssalis) Lepidoptera, Pyralidae, another name borer.The former medicine that the former medicine of test medicine metaflumizone adopts BASF Aktiengesellschaft to produce; The former medicine that dimehypo, cartap, the former medicine of desinsection list adopt Anhui Huaxing Chemical Co., Ltd. to produce; The former medicine that the former medicine of thiocyclam adopts Jiangsu Tianrong Group Co., Ltd. to produce; By technology department of Shanggezhilu Biosciences Co., Ltd., Shaanxi former medicine is mixed with the test medicine that needs, test method is soaked the rice seedling feeding method, with reference to " the agricultural industry criteria NY/T1282-2007 of the People's Republic of China (PRC) ".At first single agent and each Mixed Pharmacy are provided with 5 variable concentrations gradients (on preliminary experiment result's basis, the rice-stem borer lethality is set by geometric progression) in 5%～90% scope.The examination worm is the striped rice borer of picking up from the field, select in the laboratory three the length of time uniformity striped rice borer, insert in the dactylethrae that the rice seedling that chemicals treatment crosses is housed; Every pipe 10 cephalonts, 3 dactylethraes of every processing repeat 3 times; The dactylethrae that to handle is then put into 25 ℃ of constant incubators and is cultivated; Keep observation ward's relative moisture about 75%, 4d checks dead borer population, calculates lethality.Blank is handled the equivalent clear water.

Biological Examples 2: control paddy rice rice leaf roller field trial
The fairy house county carried out the field control effectiveness test of control paddy rice rice leaf roller to the inventor in Zhejiang Province on July 26th, 2009, had verified that this medicament is to the control efficiency of rice leaf roller, effective dose and to the safety of paddy rice.Trial crops is a paddy rice, the controlling object rice leaf roller (
Cnaphalocrocis medinalis).Adopt the conventional spraying of manual sprayer, 30 liters of every mu of spouting liquids, control paddy rice three generations rice leaf roller was investigated behind medicine in 3 days, 7 days, 10 days.Take the random sampling of balance great-jump-forward, 25 clumps of rice are looked in 5 samplings in every sub-district altogether, and statistics leaf roll rate compares with check plot leaf roll rate, calculates relative control effect, and investigating simultaneously has the worm rate in the leaf roll.While is 3,7,10 days observation paddy growth situation behind medicine, and the visual test medicament has or not poisoning to produce to paddy rice.
