Embodiment 1

[0022] Example 1 Toxicity determination of tebufenpyrad, fenbutatin and different ratios to Panonychus citrus

[0023] The test refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.12-2008". The adult mites of Panonychus citri Me Gregor on citrus were collected and reared indoors for three generations, and the female adults with uniform growth were selected as the test insects. The glass slide dipping method was used, that is, the double-sided tape was cut into 1 cm × 2 cm and pasted on one end of the glass slide, and the back of the female adult mites of Panonychus citrus was pasted on the tape. 35 to 40 mites per slide, 4 Microscopic examination after 1 hour, after picking out the dead mites, add live adult mites. Place the glass slide with the female adult mite stuck in the liquid medicine for 5 seconds, then take it out, use filter paper to absorb the excess liquid med...

Embodiment 2

[0033] Example 2: Toxicity determination of tebufenpyrad, fenbutatin and different ratios to Panonychus apple

[0034] The test refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.12-2008". The adult mites of Panonychus ulmt Koch on apple trees were collected, and after three generations of indoor rearing, female adult mites with uniform growth were selected as the test insects. Adopt glass slide dipping method, test method and statistical method are the same as embodiment 1.

[0035] The test results are shown in Table 2.

[0036] Table 2 Toxicity determination of tebufenpyrad, fenbutatin and different ratios of Panonychus apple (24h)

[0037] Test drug

[0038] It can be seen from Table 2 that when the mass ratio of tebufenfen and fenbutatin is mixed between 50:1 and 1:80, the co-toxicity coefficient of each proportion has reached more than 120, showing a cer...

Embodiment 3

[0039] Embodiment 3: the compounding method of 21% tebufenpyrad.fenbutatin emulsifiable concentrate

[0040] Tebufenpyr (active ingredient) 20%

[0041] Phentermine (active ingredient) 1%

[0042] Calcium dodecylbenzenesulfonate (emulsifier) ​​7%

[0043] Styrylphenyl polyoxyethylene ether (emulsifier) ​​4%

[0044] Dimethylformamide (solvent) 5.5%

[0045] Toluene (solvent) balance

[0046] According to the formula requirements, mix and stir tebufenpyrad, fenbutatin, emulsifier, and part of the solvent in the preparation kettle. After the solid original drug is completely dissolved, slowly add the remaining solvent, and get a uniform oil phase after fully stirring. , That is, 21% tebufenpyrad. Fenbutatin EC can be obtained.

Abstract

The invention relates to an acaricide composition and the effective ingredient of the acaricide composition comprises tebufenpyrad and fenbutatin oxide in a mass ratio of 50:1 to 1:80. The compositionhas obvious efficiency, can prevent mites on plants and particularly can prevent panonychus citri and panongchus ulmi.

Description

technical field [0001] The invention relates to an acaricidal composition, in particular to an acaricidal composition containing tebufenpyrad. Background technique [0002] Tebufenpyrad is a new type of amide acaricide. It can be used in fruit trees, tea trees, cotton, etc. to prevent and control various harmful mites such as spider mites, rust mites, and tarsal mites. Long duration, up to 40 days or more. Tebufenpyrad, as a mitochondrial respiration inhibitor, has no cross-resistance with fenbutatin, fenpropathrin, etc. [0003] Fenbutatin oxide is an organotin miticide. For fruit trees, tea trees, flowers and other crops to control citrus spider mites, rust mites, apple spider mites, tea orange gall mites, etc. The agent has been used on a large scale for many years, and the cost is relatively low. The harmful mites have developed a certain resistance to it, and the control effect has dropped a lot. [0004] Herbivorous mites are an important class of pests in the act...
