Problems solved by technology

However, the abuse of pesticides makes pests more and more resistant to pesticides, causing the control effect to decrease year by year, and also causing certain pollution to the environment. Harmless pesticides
[0003] Tetrafentezine, common name in English: clofentezine, is used to control mites on the crowns of apples and other fruit trees. It has special effects on harmful mite eggs, and has a certain effect on young mites, but the effect is slow, and generally reaches the highest after 2 weeks of treatment. Preventive effect, should not be used directly in a single dose
[0005] As of now, there has been no report on the compounding of pyrazafen and tetrafenazine

Embodiment 1

[0017] Biological Assay Example 1: Indoor Toxicity Determination Test of Pyridofen and Tetrafenzam Compounded on the Eggs of Apple Claw

[0018] Test object: Mite eggs of apple panonychus ulmi Koch, artificially reared indoors for 9 generations.

[0019] Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.12-2006", put the bottom of a small plastic petri dish with a diameter of 5 cm downwards in the bottom of a petri dish with a diameter of 9 cm, and lay the folded flat on the small petri dish Cotton, cotton must be larger than the surroundings of the small petri dish so that it can absorb water, spray the cotton with water, add an appropriate amount of water in the large petri dish so that the water level is at 1 / 4 of the height of the dish. Cut fresh, healthy and disease-free apple leaves into rectangular leaf discs of 2 x 3 cm, and stick the back of the leaves on wet cotton in a small petri dish.

Embodiment 2

[0030] Biological Assay Example 2: Indoor Joint Toxicity Determination Test of Pyridofen and Tetrafenazine on P.

[0031] Test object: Apple Panonychus ulmi Koch larvae, artificially reared indoors for eight generations.

[0032] Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.13-2008", put the bottom of a small plastic petri dish with a diameter of 5 cm downwards in the bottom of a petri dish with a diameter of 9 cm, and lay the folded flat on the small petri dish Cotton, cotton must be larger than the surroundings of the small petri dish so that it can absorb water, spray the cotton with water, add an appropriate amount of water in the large petri dish so that the water level is at 1 / 4 of the height of the dish. Cut fresh, healthy and disease-free apple leaves into rectangular leaf discs of 2 x 3 cm, and stick the back of the leaves on wet cotton in a small petri dish.

Embodiment 2

[0042] Formulation example 2: 41% pyraclofen tetrafenazine emulsifiable concentrate

[0043] 40% pyraclofen, 1% tetrafenazine, 4% calcium dodecylbenzenesulfonate, 3% phenethylphenol polyoxyethylene ether, and vegetable oil to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing cream, and then mix them to obtain 41% pyraclofen-tetramethazine cream.

Abstract

The invention discloses a synergia mite-killing compound containing nitrile pyrazole mite ester. The effective constituent comprises nitrile pyrazole mite ester and mite tetrazine at a mass ratio of (50:1) to (1:50). The total mass percentage of the effective constituent in the compound is 15%-80%. The synergia mite-killing compound can be prepared into agriculturally allowed suspending agent, suspoemulsion, microemulsion, water dispersible granule, missible oil, water emulsion, wettable powder, micro-capsule suspending agent or dispersing oil suspending agent. The synergia mite-killing compound is reasonable in component and can effectively kill various mite insects on the crops and flowers, such as, fruit trees, vegetables, and the like; compared with the present single preparation, the compound has an obvious mite-killing effect and obvious synergism; the pesticide usage is reduced, so that the use cost and the pollution to environment are reduced; the drug-fast control for the mite is benefited; the popularization and application of the compound have large economic and social benefits.

Description

technical field [0001] The invention relates to a synergistic acaricidal composition, in particular to a synergistic acaricidal composition containing pyraclofen and its application in preventing and controlling acarid pests on crops, belonging to the technical field of compound pesticides. Background technique [0002] There are many generations of pest mites on crops, overlapping generations, a long occurrence time, a large amount of occurrence, and serious damage. They need to be controlled for many years, and a large amount of pesticides are needed every year to prevent and control pest mites. However, the abuse of pesticides makes pests more and more resistant to pesticides, causing the control effect to decrease year by year, and also causing certain pollution to the environment. Harmless pesticides. [0003] Tetrafentezine, common name in English: clofentezine, is used to control mites on the crowns of apples and other fruit trees. It has special effects on harmful m...
