Abstract
The invention discloses an acaricidal composition containing pyriminostrobin and tebufenpyrad. The acaricidal composition takes pyriminostrobin and tebufenpyrad as active ingredients, wherein the weight ratio of pyriminostrobin to tebufenpyrad is (1: 5)-(5: 1). The composition can be prepared into a dosage form of suspension, wettable powder, water dispersible granules, missible oil or microemulsion. The composition is reasonable in composition and good in acaricidal effect, and activity and acaricidal effect of the composition are not simple superposition of activities and acaricidal effects of various components; the composition, compared to an existing single preparation, not only has an obvious insecticidal efficacy but also is remarkable in synergistic effect, and is good in crop safety and consistent with safety requirement of a pesticide preparation. The composition has obvious effect on preventing and controlling panonychus citri, panonychus ulmi and cotton red spider.
Description
Technical field
The present invention relates to a kind of miticide composition, main active is phonetic mite amine and tebufenpyrad, 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 crops such as main harm oranges and tangerines, apple, cotton, vegetables, wheat, evil mite is gathered in vacuum side of blade more, with adult, nymph, with mouthpart, thrusts and in leaf, sucks juice harm.When evil mite occurs, with miticide control, be the most effective means, medicament at Ministry of Agriculture's registration control Agricultural Mites mainly contains Avermectin, pyridaben, propargite, fenbutatin oxide etc. at present, evil mite has produced resistance to it, in the urgent need to inventing a kind of agricultural chemicals that can effectively prevent and treat 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 to becoming mite mite, ovum all to have greater activity, 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 mixed from the miticide of the different mechanisms of action, for fully effectively promoting phonetic mite amine, extends its service life and have important function.

Biological Examples: control citrus red mite field trial
Inventor has carried out the phonetic mite amine of example of formulations 2(20% tebufenpyrad suspending agent in Hanzhong City Chenggu County, Shaanxi Province in May, 2013) control citrus red mite field control effectiveness test, verified that this medicament is 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 clear water blank.Every processing repeats 5 trees of ，Mei community area 4 times, Gong24Ge community, and random district group is arranged.Adopt manual sprayer evenly to spray.Respectively within before medicine, after medicine 1 day, 7 days, 14 days, respectively carrying out once residual borer population investigation.2 trees are looked in every community, and every tree is looked into respectively 5 Pian Ye，Mei communities by orientation, 4 of the four corners of the world and looks into altogether 40 leaves, record the mite number of living, and carry out control efficiency statistics.Viewing test medicament has or not poisoning to produce to oranges and tangerines simultaneously.
Computational methods:
Control efficiency (%)=[1-(borer population after the front borer population * treatment region medicine of check plot medicine)/(the front borer population of borer population * treatment region medicine after the medicine of check plot)] * 100
Result of the test shows, 20% 2000 times, 2500 times, 3000 times of phonetic mite amine tebufenpyrad missible oil dilutions, citrus red mite is had to good control efficiency, after medicine, the preventive effect of 1,7,14 day is all more than 91.6%, show excellent quick-acting and lasting effect, be obviously better than the control efficiency (table 4) of 10% 1000 times of phonetic mite amine suspending agents, 1500 times of 20% tebufenpyrad missible oil.Advise that 2000～3000 times of 20% phonetic mite amine tebufenpyrad suspending agent control citrus red mite dilutions are 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 tebufenpyrad are mixed, has obviously improved the control efficiency to citrus red mite, and synergistic effect is obvious, shows excellent quick-acting and lasting period, has reduced dosage, has saved drug cost, to Ci trus growth safety.
In sum, composition of the present invention is to adopt two kinds of active component compound schemes, its activity and insecticidal effect are not the simple superposition of each composition activity, compare with existing unitary agent, except having significant insecticidal effect, and have significant synergistic effect, and good to crop safety, meet the security requirement of pesticidal preparations.
