Problems solved by technology

[0004] Acarids have the characteristics of strong reproductive ability, fast development speed, short development cycle, serious damage, and easy resistance to drugs. Therefore, chemical control agents must have quick-acting effects and long-lasting effects. After 2-3 years of use, the control effect drops significantly; the compound agent is an important means of chemical control

Embodiment 1

[0024] Example 1. A compound insecticidal / acaricidal composition containing spirobudiclofen, which consists of 1 part of spirobudiclofen and 10 parts of amitraz.

[0025] According to the preparation method of conventional emulsion in water, make as follows:

[0026] 11% compound insecticidal / mite-killing composition, 7% alkylphenol polyoxyethylene ether, 4% tallow ethoxylated amine salt, 2% N,N-dimethylformamide, No. 1500 solvent (1500 No. 10% solvent naphtha) and 2% epichlorohydrin into a high-speed shear mixing emulsifier, and the oil phase is obtained after high-speed shearing. Put 2% aluminum magnesium silicate, 4004% polyethylene glycol, and distilled water into another high-speed shear mixing emulsifier to make up to 100%. After mixing evenly, the water phase is obtained. Under the condition of shearing, add it dropwise into the oil phase, adjust the pH value of the system to 6-7 with pH buffer solution after the dropping, and continue shearing for 15-30 minutes to obt...

Embodiment 2

[0027] Embodiment 2. A compound insecticidal / acaricidal composition containing spirobudiclofen, which consists of 20 parts of spirobudiclofen and 5 parts of amitraz.

[0028] According to the preparation method of conventional emulsion in water, make as follows:

[0029] 25% compound insecticidal / mite-killing composition, 5% N,N-dimethylacetamide, 5% No. 2000 solvent, styrene phenol formaldehyde resin polyoxyethylene ether (styrene phenol polyoxyethylene ether formaldehyde resin ) 6%, 5% sodium starch octenyl succinate, and 3% epichlorohydrin were put into a high-speed shear mixing emulsifier, and the oil phase was obtained after high-speed shearing. Put 3% glycerol, 2% aluminum magnesium silicate, and distilled water into another high-speed shear emulsifier to make up to 100%. After mixing evenly, the water phase is obtained. Add it dropwise to the oil phase under the condition of cutting. After the dropwise addition, adjust the pH value of the system to 6-7 with pH buffer s...

Embodiment 3

[0030] Embodiment 3. A compound insecticidal / acaricidal composition containing spirobudiclofen, which consists of 20 parts of spirobudiclofen and 30 parts of amitraz.

[0031] According to the preparation method of conventional suspending agent, make as follows:

[0032] 50% compound insecticidal / mite-killing composition, 3.0% fatty alcohol polyoxyethylene ether, 1.0% tallow ethoxylated amine salt, 2.0% acyl glutamate, 3.0% polymer polycarboxylate, naphthalene Sulfonic acid condensate sodium salt (naphthalene sulfonic acid formaldehyde condensate sodium salt) 1.0%, dioctyl sulfosuccinic acid sodium salt 1.0%, urea 3.0%, silicone defoamer 0.1%, deionized water added to 100 %, put it into a high-shear homogeneous emulsifier for high-speed shearing for 20 minutes, and then use a high-pressure homogenizer to homogenize to obtain a 50% insecticidal suspension containing spirobudiclofen and amitraz.

Abstract

The invention discloses a compound pest / mite killing composition containing spirodiclofen double ester. The compound pest / mite killing composition is preapred from the following components in parts by weight: 1-20 parts of spirodiclofen double ester and 5-30 parts of amitraz, wherein the weight ratio of spirodiclofen double ester to amitraz is 1: (0.2-20). The compound pest / mite killing composition containing spirodiclofen double ester can be prepared into EW (emulsion in water), suspending agents and suspoemulsion, can effectively kill mites or pests such as citrus red mites, two-spotted spider mites, tetranychus cinabarinus Boisdu, pear psylla and diaphorina citri.

Description

technical field [0001] The invention relates to a compound insecticidal and acaricidal composition containing amitraz and spirobudiclofen and its application. Background technique [0002] Spirodiclofen is a non-systemic acaricide. It mainly controls eggs, nymphs and female adults through contact and stomach poisoning. Its mechanism of action is to inhibit fat synthesis in the body of harmful mites and block energy metabolism. It has no cross-resistance with conventional acaricides; its ovicidal effect is outstanding, and it has good control effect on harmful mites (except male adult mites) at different developmental stages, and can be safely used in the control of fruit trees, vegetables and flowers . However, spirodiester also has the problems of poor quick-acting effect (7-10 days after application), high cost, and narrow control area (only mites are effective). [0003] Amitraz is a broad-spectrum insecticide and acaricide. It has contact killing, stomach poisoning, fu...
