Embodiment 5

[0028] Formulation example 5: 60% pyrazafen·etoxazole water dispersible granules.

[0029] 40% pyraclofen, 20% etoxazole, 10% alkylphenol polyoxyethylene ether, 10% sodium dodecylbenzenesulfonate, 3% sodium carbonate, 2% polyvinyl alcohol, and 100% kaolin. Mix the above-mentioned effective ingredients, dispersant, wetting agent, disintegrant, binder and filler uniformly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, After sieving, 60% pyraclofen-etoxazole water-dispersible granules can be obtained.

[0030] Formulation example 6: 20% pyraclofen-etoxazole ultra-low volume solution.

[0031] 15% pyraclofen, 5% etoxazole, 10% N-methylpyrrolidone, 15% N,N-dimethylformamide, 2% calcium dodecylbenzenesulfonate, castor oil polyoxyethylene ether 2%, double kill 1.5%, and the second-line oil makes up to 100%. After stirring and dissolving the above-mentioned active ingredients with a solvent, then adding othe...

Embodiment 7

[0032] Formulation example 7: 10% pyraclofen-etoxazole microcapsule suspension

[0033] Cyclofenpyrafen 7%, etoxazole 3%, aliphatic polyamide resin 8%, corn methyl ester oil 10%, polyoxyethylene lauryl ether 10%, sodium hydroxide 2%, polycarboxylate 3%, to Ionized water tops up to 100%. Mix the above-mentioned effective ingredients, polymer capsule wall materials, and solvents to dissolve into a uniform oil phase. Under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifiers, pH regulators, and dispersants. Make up with deionized water, the two materials react at the oil-water interface to form a polymer capsule wall, and then the 10% pyraclofen-etoxazole microcapsule suspension can be prepared.

Embodiment 1

[0036] Biological Assay Example 1: Indoor Joint Toxicity Test for Citrus Spider Mite with Bezafenid and Etoxazole.

[0037] Insects to be tested: Citrus red spider nymphs collected in the field and bred indoors.

[0038] Drugs to be tested: 96% of the original drug of pyraclofen and 93% of the original drug of etoxazole.

[0039] The test method adopts the leaf butterfly spray method, and the specific operation method is as follows:

[0040] Choose healthy citrus leaves, make leaf butterflies with a puncher, place a wet sponge block in a petri dish, put filter paper on it, put leaf butterflies on the filter paper, put 2 leaf butterflies in each dish, choose healthy, aged Inoculate citrus spider mite nymphs with the same period of time to leaf butterflies, and inoculate 20 heads per leaf butterfly.

[0041]Place the petri dish connected with the leaf butterfly under the potter spray tower, spray under 50PSI pressure, the spray volume is 1ml, take out the petri dish after sett...

Abstract

The invention relates to a synergetic acaricidal composition containing cyenopyrafen and etoxazole. The weight ratio of the cyenopyrafen to the etoxazolein parts is (20:1)-(1:20), and the sum of the weight of the cyenopyrafen and the weight of the etoxazole accounts for 5%-85% of the synergetic acaricidal composition in percentage by weight. According to the invention, the effective components of the cyenopyrafen and the cyflumetofen are compounded, so that the synergetic acaricidal composition has an obvious synergetic effect, and has an excellent control effect on various acarine pests on crops, flowers and plants, such as fruit trees, vegetables, cotton and tea trees. According to the invention, the control effect is improved, and the usage amount of agricultural chemicals is reduced, so that the cost is reduced, the environmental pollution is reduced, the resistance management to the pest mites is facilitated, and the synergetic acaricidal composition has higher economic benefits and social benefits for popularization and application.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a synergistic acaricidal composition with pyrazafen and etoxazole as active ingredients, which is mainly used in the prevention and control of acarid pests in agriculture. Background technique [0002] Cyenopyrafen: It belongs to a new type of pyrazole acaricide. The mechanism of action is that the agent is metabolized into a hydroxyl form and activated to produce activity. This hydroxyl form inhibits the mitochondria by disturbing the complex II in the respiratory electron transport chain. Efficacy, thereby hindering electron transfer and destroying the process of oxidative phosphorylation. It is mainly used to control various harmful mites on eggplant, pepper, cucumber, pear, strawberry, citrus and other fruits, vegetables, and tea. It has good quick-acting and long-lasting Effectiveness. [0003] Etoxazole: It belongs to diphenyloxazoline derivatives. Its m...
