Embodiment 5

[0028] Formulation example 5: 50% water-dispersible granule of pyrafen-butafen-butaflufen.

[0029] 20% fenpyrafen, 30% cyflufen, 10% alkylphenol polyoxyethylene ether, 10% sodium dodecylbenzenesulfonate, 3% urea, 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, By sieving, 50% water-dispersible granules of cyflumetate and cyflumetofen can be obtained.

[0030] Formulation example 6: 20% cyflumetofen-butaflufen ultra-low volume liquid formulation.

[0031] Cyclofenpyr 5%, Cyflumetate 15%, N-Methylpyrrolidone 10%, N,N-Dimethylformamide 10%, Sodium Lauryl Sulfate 3%, Castor Oil Polyoxyethylene Ether 2 %, double killing 1.5%, cottonseed oil supplemented to 100%. After stirring and dissolving the above-mentioned active ingredients with a solvent, other a...

Embodiment 2

[0050] Biological Assay Example 2: Field efficacy test of the combination of cyprofen and cyflumetofen against citrus spider mite.

[0051] Adopt 30% pyrafenpyrofen · cyflumetone suspension concentrate (preparation example 1) to be used for preventing and treating citrus spider mite, investigate the population base of insects before spraying, and investigate the number of residual live mites respectively at 7d, 14d, and 30d after the spraying. Check 2 plants in each plot, check 5 leaves of each plant according to 4 directions of east, west, north, south, respectively, check 40 leaves in each plot, record the number of live mites, and calculate the control effect. The control effect calculation method is as follows:

[0052] Control effect (%) = (1-CK 1 ×Pt 1 / CK 2 ×Pt 2 )×100.

[0053] Among them: CK 1 Represents the number of worms in the control area before the drug; Pt 1 Represents the number of insect populations after treatment in the treatment area;

[0054] CK ...

Abstract

The invention relates to a synergetic acaricidal composition containing cyenopyrafen and cyflumetofen. The weight ratio of the cyenopyrafen to the cyflumetofen is (20:1)-(1:20), and the sum of the weight of the cyenopyrafen and the weight of the cyflumetofen accounts for 5%-80% 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 mite-killing composition, which is used for preventing and controlling agricultural pest mite by taking cyfenpyrafen and cyflumetofen as active ingredients. 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. Effectiveness, thereby hindering electron transfer and destroying the process of oxidative phosphorylation; mainly used to prevent and control various pest mites on eggplant, pepper, cucumber, pear, strawberry, citrus and other fruits, vegetables, and tea, with good quick-acting and long-lasting Effectiveness. [0003] Cyflumetofen: a new type of acyl acetonitrile acaricide, the mechanism of action is to inhibit mitochondrial electron conducti...
