Embodiment 1

[0024] Example 1 Toxicity determination of tebufenpyrad, fenpropathrin and different ratios to Tetranychus cinnabarinus

[0025] The adult mites of Tetranychus cinnabarinus were collected from the eggplant field, and after three generations of indoor breeding, the female adult mites with uniform growth were selected as the test insects. 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". Using the glass slide dipping method, that is, cut the double-sided tape into 1cm×2cm and paste it on one end of the glass slide, and stick the back of the female adult mite of Tetranychus cinnabarinus on the tape, 35-40 mites per slide, 4 hours After microscopic examination, after picking out dead mites, live adult mites were added. 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 ...

Embodiment 2

[0034] Example 2: Toxicity determination of tebufenpyrad, bifenthrin and different ratios to Tetranychus urticae

[0035] Adult mites of Tetranychus urticae in cotton fields were collected and reared indoors for three generations, and female adults with uniform growth were selected as test insects. 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". Adopt glass slide dipping method, test method and statistical method are the same as embodiment 1.

[0036] The test results are shown in Table 2.

[0037] Table 2 Toxicity determination of tebufenpyrad, bifenthrin and different ratios to Tetranychus urticae (24h)

[0038] Test drug

[0039] It can be seen from Table 2 that when the mass ratio of tebufenpyrad and bifenthrin is mixed between 50:1 and 1:100, the co-toxicity coefficient of each proportion has reached more than 120, indicating that th...

Embodiment 3

[0040] Example 3: Preparation method and field efficacy test of 21% tebuflufen-fenpropathrin emulsifiable concentrate

[0041] 95% tebufenfen (active ingredient) 21.05g

[0042] 95% fenpropathrin (active ingredient) 1.05g

[0043] Calcium dodecylbenzenesulfonate (emulsifier) ​​3.2g

[0044] Styrylphenol ethoxylate (emulsifier) ​​4.3g

[0045] Alkylphenol formaldehyde resin polyoxyethylene ether (emulsifier) ​​4.1 grams

[0046] Toluene (solvent) make up to 100g

[0047] According to the formula requirements, mix and stir tebufenpyrad, fenpropathrin, 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 after fully stirring. phase, that is, to prepare 100 g of 21% tebufenfen-fenpropathrin emulsifiable concentrate (the mass ratio of tebuflufen and fenpropathrin is 20:1).

[0048] Dilute 21% tebufenpyrad-fenpropathrin emulsifiable concentrate with water 500...

Abstract

The invention relates to an agricultural composition; and the effective ingredient of the agricultural composition comprises a component A and a component B in a mass ratio of 50:1 to 1:100. The component A is tebufenpyrad, and the component B is pyrethrins pesticide which is fenpropathrin, bifenthrin, high-efficiency cyfluthrin, or high-efficiency lambda-cyhalothrin. The composition has the synergy and is used for preventing mites on plants.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing tebufenfen, which is used for preventing and controlling harmful mites on plants. Background technique [0002] In the actual process of agricultural production, the most likely problem in pest control is the resistance of pests. Agriculturally important pest mites are particularly prone to resistance due to their short reproductive cycle, large reproductive capacity, small movement, and high degree of self-fertilization. [0003] Fenpropathrin, bifenthrin, beta-cyfluthrin, and lamda-cyhalothrin are commonly used pyrethroid insecticides and acaricides. Its insecticidal mechanism is to act on the nervous system of pests and pest mites. When pests and harmful mites occur concurrently, it can treat both pests and mites. For a long time, with the extensive use of this type of pesticide, many pests and pest mites have developed high resistance to it, and...
