Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and the speed of pest resistance can never be compared
Other methods, such as crop layout adjustment, biological control, etc., are difficult to achieve obvious effects in the actual operation process
[0007] In my country, the current dependence on imported acaricides such as spirodiclofen is strong, and they are not easy to obtain and are expensive. Their use is mostly limited to some economically developed areas and cannot be used by farmers in all areas in need; due to resistance The problem is that other commonly used and cheap acaricides are less effective

Embodiment 1

[0046] Example 1: 20% Spirodiclofen·Liuyangmycin EC

[0047] Spirodifen 10%

[0048] Liuyangmycin 10%

[0049] Calcium dodecylbenzenesulfonate 4%

[0050] Tristyryl polyoxyethylene ether 3%

[0051] N-Methylpyrrolidone 10%

[0052] Xylene to 100%

[0053] The active ingredient, emulsifier and auxiliary agent are sequentially added into the mixing kettle according to the proportion of the formula, and stirred evenly to prepare 20% spirodiclofen·liuyangmycin EC.

[0054] This embodiment is applied to the control of Panonychus on citrus. Dilute 20% Spirodiclofen·Liuyangmycin EC to 3000 times of water and spray it evenly. The control effect is 88.7% one day after the application. Using the same method, the control effect of 1 day after the drug was 59.6% and 85.2%, and the quick effect was significantly better than that of spirodiclofen; the control effect of 15 days after the drug was 97.6%. Mymycin emulsifiable concentrate was used in the same way by 1000 times, and the con...

Embodiment 2

[0056] Example 2: 27% Spirodiclofen·Liuyangmycin Suspension Concentrate

[0057] Spirodifen 24%

[0058] Liuyangmycin 3%

[0059] Alkylaryl polyoxypropylene polyoxyethylene ether 8%

[0060] Sodium polynaphthalene sulfonate 2%

[0061] Glycerol 3%

[0062] Magnesium Aluminum Silicate 1%

[0063] water to 100%

[0064] According to the formula requirements, add the pre-crushed original drug and carrier, surfactant, thickener, stabilizer, antifreeze, water, etc. into the sand mill, grind it finely, then mix it by high-speed shearing, and finally adjust the pH with acetic acid To 4 to prepare 27% spirodiclofen·liuyangmycin suspension concentrate.

[0065] This embodiment is applied to the prevention and treatment of Panonychus on sweet oranges. Dilute and spray 27% Spirodiclofen·Liuyangmycin SC by 5000 times with water, and the control effect is 98.2% 15 days after the application. Using the same method, the control effects were 84.3% and 79.4% 15 days after the drug, and...

Embodiment 3

[0067] Example 3: 60% spirodiclofen·liuyangmycin water dispersible granules

[0068] Spirodifen 50%

[0069] Liuyangmycin 10%

[0070] Sodium lignosulfonate 6%

[0071] Sodium alkyl naphthalene sulfonate 5%

[0072] Sodium Lauryl Sulfate 2%

[0073] Ammonium Sulfate 6%

[0074] Attapulgite to 100%

[0075] Mix the active ingredient, dispersant, wetting agent, disintegrating agent and filler according to the ratio of the formula, and crush it into a wettable powder by airflow, then add a certain amount of water to mix and extrude the material, and obtain 60% after drying and sieving % spirodiclofen·liuyangmycin water dispersible granules.

[0076] This embodiment is applied to control two-spotted spider mite on tomato. The formula is diluted with water by 25000 times and sprayed, and the control effect is 93.2% 15 days after the application. 24% spirodiclofen suspending agent is used by 5000 times and 10% Liuyangmycin EC by 1000 times. Using the same method, the control ...

Abstract

The invention relates to an acaricide composition containing tetronic acid active substances. The active ingredients of the acaricide composition are spirodiclofen (A) and liuyangmycin (B), the mass ratio of A to B is between 10 to 1 and 1 to 10; and according to the prior method, the original drug containing the active ingredients and auxiliary materials are processed together to be prepared into any dosage form suitable for agricultural application, wherein the better dosage forms comprise emulsifiable solution, suspending agents, water emulsion, water dispersible granules and the like, andthe total content of the active ingredients in the preparation is between 5 and 80 percent. The acaricide composition has obvious synergism on controlling pest mites on crops, has good quick effect and long duration, and is helpful to delay the drug resistance generation of the pest mites; and the acaricide composition is mainly used for controlling the pest mites on the crops such as fruit trees, cottons, and vegetables.

Description

technical field [0001] The present invention relates to a pesticide composition and its application, in particular, it is an acaricidal composition with spirodiclofen and liuyangmycin as active ingredients, which is used to prevent and control agricultural acarid pests, especially suitable for the prevention and treatment of fruit trees, vegetables, Tetranychus on flowers. technical background [0002] Spirodiclofen, also known as quaternary ketone acaricide, is a new type of quaternary acid acaricide. The mechanism of action is to destroy the energy metabolism of mites by inhibiting the synthesis of fat in the body of harmful mites. It has excellent effect on mite eggs and good contact activity on juvenile nymphs, but has poor contact effect on female adult mites, and cannot quickly control the damage when harmful mites occur in large numbers. It is a high-efficiency non-systemic foliar treatment acaricide, and there is no cross-resistance problem with other existing acar...
