Abstract
The invention discloses an acaricidal composition containing pyriminostrobin and cyflumetofen. Effective active ingredients of the acaricidal composition consist of pyriminostrobin and cyflumetofen, and the weight ratio of pyriminostrobin to cyflumetofen is (1: 10) to (10: 1). The composition disclosed by the invention can be prepared into agriculturally-acceptable preparation forms, such as suspensions, wettable powder, water-dispersible granules and dispersible oil suspensions. According to the acaricidal composition, the ingredients are reasonable, the insecticidal effect is good, and the activity and insecticidal effect of the acaricidal composition are not achieved through the simple superposition of the activity of each component; compared with the existing single preparation, besides having a remarkable insecticidal effect, the acaricidal composition has a remarkable synergism has good safety to crops and meets the requirements of pesticide preparations for safety; the acaricidal composition has remarkable prevention and treatment effects on Panonychus citri McGregor, Panonychus ulmi and Tetranychus cinnabarinnum Boisduval.
Description
Technical field
The present invention relates to a kind of miticide composition, its effective active composition is phonetic mite amine and cyflumetofen, belongs to technical field of compounded pesticide.
Background technology
Harmful mite in agricultural production is also two spotted spider mite, yellow spider etc., belongs to arachnids Acarina.The crop such as main harm oranges and tangerines, apple, cotton, vegetables, wheat, evil mite be gathered in vacuum side of blade more, with adult, nymph with mouthpart thrust in leaf suck juice harm.When evil mite occurs, preventing and treating with miticide is the most effective means, Avermectin, pyridaben, propargite, fenbutatin oxide etc. are mainly contained at present at the medicament of Ministry of Agriculture's registration control Agricultural Mites, evil mite produces resistance to it, in the urgent need to inventing a kind of agricultural chemicals effectively can preventing and treating harmful mite and safety nuisance free.
Phonetic mite amine, English common name: pyriminostrobin, its structural formula is as follows:
Phonetic mite amine is methoxy acrylic miticide, has bactericidal activity simultaneously, if all have greater activity to one-tenth mite mite, ovum, quick-acting is good, and lasting effect is general.As a kind of new miticide, in use there is resistance risk in phonetic mite amine, and rationally uses with from the miticide of the different mechanism of action, for fully effectively promoting phonetic mite amine, extending its service life and having important function.
Cyflumetofen, chemical name: (RS)-2-(4-t-butyl-phenyl) 2-cyano group-3-oxo-3-(α, α, α-three fluoro-o-methyl-benzene) acid of propionic acid-2-methoxyethyl, english common name cyflumetofen.Cyflumetofen is novel acyl acetonitrile class miticide, with existing insecticide without cross resistance, to the ovum of tetranychid with to become mite all effective, if higher to the activity of mite.Simultaneously to each Plants all without poisoning, all fool proof to non-target organisms such as mammal and aquatile, beneficial organism, natural enemies.
Inventor does not also find that there is through retrieval the bibliographical information being used for phonetic mite amine and cyflumetofen mixture to prevent and treat Agricultural Mites, find phonetic mite amine and cyflumetofen mixture to use have good control efficiency to Agricultural Mites by lot of experiments, have the advantages that quick-acting is good, the lasting period is long, there is significant synergistic effect, have received beyond thought effect, can use cost be reduced, effectively solve the problem of control of pest mite difficulty.

Embodiment
In order to prevent and treat the harmful mite in agricultural production, inventor has carried out mutual composite synergy with phonetic mite amine and cyflumetofen and has studied.Concrete grammar is:
Subjects be citrus red mite (
panonychus citfimcGregor), European red mite (
panonychus ulmi), cotton red spider (Tetranychus cinnabarinnum Boisduval).Former medicine is mixed with the test medicine of needs, test method is with reference to " People's Republic of China (PRC) agricultural industry criteria NY/T1154.13-2008 ".First single dose and each Mixed Pharmacy are arranged 5 variable concentrations gradients (on the basis of preliminary experiment result, two spotted spider mite lethality sets by geometric progression in the scope of 5% ~ 90%).Examination worm is the two spotted spider mite of picking up from field, if select the mite of uniformity in the length of time in laboratory, put into blade-carrying culture dish, 40, every ware, often process 4 culture dishes, repeat 3 times, spray under 50PSI pressure with potter spray tower, each spray ware, every ware spraying liquid 3ml, then the culture dish processed is put into 12H/12H illumination box to cultivate, within 48 hours, check dead borer population, calculate lethality.Blank spray equivalent clear water
.calculate lethality.By the linear regression analysis between the probit value of lethality and the logarithm value of series concentration, obtain the LC of each medicament
50value, calculates the co-toxicity coefficient (CTC) of mixture by the abundant method of Sun Yun, evaluate the activity of reagent agent to examination worm with this.
The co-toxicity coefficient (CTC) >=120 of complex preparation shows as synergistic effect; CTC≤80 show as antagonism; 80 < CTC < 120 show as summation action.
Toxicity Determination result shows: phonetic mite amine and cyflumetofen are that 1:10 ~ 10:1 is mixed with weight ratio all has good virulence to citrus red mite, European red mite and cotton red spider, has significant synergistic effect.

Biological Examples: control citrus red mite field trial
Inventor has carried out example of formulations 1(20% phonetic mite amine cyflumetofen suspending agent in April, 2013 in Hanzhong City Chenggu County, Shaanxi Province) prevent and treat the field control effectiveness test of citrus red mite, demonstrate this medicament to the control efficiency of citrus red mite, effective dose and the safety to oranges and tangerines.Test medicine and extension rate refer to table 4, separately establish blank.Often process and repeat for 4 times, every plot area 5 tree, Gong24Ge community, random district group arranges.Manual sprayer is adopted evenly to spray.Borer population investigation is respectively once remained respectively at before medicine, after medicine 1 day, 7 days, 14 days.2 trees are looked in every community, and every tree looks into 5 leaves respectively by orientation, 4, the four corners of the world, and every community looks into 40 leaves altogether, record mite number of living, carry out control efficiency statistics.Viewing test medicament produces with or without poisoning oranges and tangerines simultaneously.
Computational methods:
Control efficiency (%)=[1-(before the medicine of check plot after borer population × treatment region medicine borer population)/(before borer population after the medicine of check plot × treatment region medicine borer population)] × 100.
Result of the test shows, 20% phonetic mite amine cyflumetofen suspending agent dilutes 2000 times, 2500 times, 3000 times, good control efficiency is had to citrus red mite, after medicine, the preventive effect of 1,7,14 day is all more than 88.4%, show excellent quick-acting and lasting effect, be obviously better than the control efficiency (table 4) of 15% phonetic mite amine suspending agent 1000 times, 20% cyflumetofen suspending agent 2000 times.Advise that 20% phonetic mite amine cyflumetofen suspending agent control citrus red mite dilution 2000 ~ 3000 times is advisable.
Security survey, duration of test is observed, and all reagent agents, to Citrus leaf, the tender tip, flower, growth of young safety, occur without poisoning phenomenon.
Result of the test shows, after phonetic mite amine and cyflumetofen mixture, significantly improves the control efficiency to citrus red mite, and synergistic effect is obvious, shows excellent quick-acting and lasting period, reduces dosage, saved drug cost, to Ci trus growth safety.
In sum, composition of the present invention is employing two kinds of active component compound schemes, its activity and insecticidal effect are not the simple superposition of each composition activity, compared with existing unitary agent, except there is significant insecticidal effect, and have significant synergistic effect, and good to crop safety, meet the security requirement of pesticidal preparations.
