Problems solved by technology

[0009] The above-mentioned medicaments for preventing and controlling Tetranychus cinnabarinus, gall mites, Tetranychus urticae and Tetranychus hawthorn are likely to cause the problem that harmful mites develop resistance to a single acaricide because of a single acaricide variety, and the control effect is reduced. bigger
At the same time, the extensive use of medicaments increases pesticide residues, endangers food safety, and aggravates environmental pollution.

Embodiment 2、30

[0063] Example 2. 30% emulsifiable concentrate, effective ingredient ratio 5:1

[0064] Compound A 25%, Abamectin 5%, Nongru 2201# 6%, Nongru 0201B 8%, Cyclohexanone 8%, Solvent oil 150 to make up to 100%.

[0065] Abamectin can also be replaced with spinosyn, spiromesifen, benomyl, diflubenzuron, ethenoxafen, fluazinam, bifenazate, and fluorobutanol in compound B described in the specification. One of dicofen, pyridaben, and spirodiclofen forms a new water emulsion product.

[0066] 2. Preparation of wettable powder

[0067] According to the requirements of the formula, the original medicine, various additives and fillers are fully mixed, and then pulverized by an ultrafine grinder to obtain a processed product.

Embodiment 3、50

[0068] Example 3. 50% wettable powder

[0069] Compound A 45%, avermectin 5%, sodium dodecylbenzene sulfonate 1.8%, p-tert-butyl ether 2%, white carbon black 10%, sodium lignin sulfonate 10%, light calcium carbonate supplement To 100%.

Embodiment 4、40

[0070] Example 4. 40% wettable powder

[0071] Compound A 38%, abamectin 2%, sodium dodecylbenzene sulfonate 2%, p-tert-butyl ether 2%, white carbon black 5%, sodium lignin sulfonate 10%, light calcium carbonate supplement To 100%.

[0072] Abamectin can also be replaced with spinosyn, spiromesifen, benomyl, diflubenzuron, ethenoxafen, fluazinam, bifenazate, and fluorobutanol in compound B described in the specification. One of dicofen, pyridaben, and spirodiclofen forms a new water emulsion product.

[0073] 3. Preparation of water dispersible granules

[0074] The original medicine is mixed and crushed with the powdered carrier, the wetting spreading agent and the binder, and then kneaded with water, and then added to a granulator equipped with a certain specification screen for granulation. Then it is dried and sieved (according to the screen range) to obtain granular products.

Abstract

The invention discloses an acaricidal composition containing biphenyl synergistic acaricides. The acaricidal composition contains two active components. The first component is a biphenyl synergistic acaricide A. The second component is selected from other acaricide active component formulations. A weight ratio of the synergistic acaricide A to the other acaricide formulations is 1:50-50:1. According to the invention, the obtained composition has an excellent control effect by compounding the synergistic acaricide A and the other acaricide formulations. Meanwhile, the composition enlarges an acaricidal spectrum and has a synergistic effect. The acaricidal composition provided by the invention can improve the control effect, reduce the agricultural cost and delay the generation of insecticide resistance of pests, has good control effect on panonchus citri M., xiupi lice, polyphagotarsonemus latus Banks, tetranychus cinnabarinus, twos potted spider mites and other pest mites, can be usedfor mete control of fruit trees, such as citrus and grapes, and solanaceous crops, such as eggplants, peppers and tomatoes. In addition, the acaricidal composition provided by the invention also has good control effect on pear psylla, lepidosaphes ulmi and leafhopper kind insects.

Description

Technical field [0001] The invention relates to a mite-killing composition and a method for preventing and controlling plant diseases. Background technique [0002] Agricultural pest mites are small in size, fast in reproduction, strong in adaptability, and easy to produce resistance. They are one of the most difficult pests to control. Pest mites are important hazards to fruit trees, vegetables, and agricultural and forestry crops. They mainly damage leaves, but also young shoots, flower buds and fruits. After the number of insects increases sharply, plants often fall leaves, inhibit their growth and even die. The crops in the affected areas are often slightly shorter, and their quality and yield are significantly reduced. [0003] Tetranychus cinnabarinus, Tetranychus urticae, Tetranychus urticae, and Tetranychus hawthorn are common multiple harmful mites in crops such as melons, fruit trees, and vegetables, which seriously affect the yield and quality of products and often bec...
