Problems solved by technology

However, the defect of pyrethroid insecticides is that the resistance of pest mites to such agents increases rapidly. At present, many pest mites such as cotton bollworm, diamondback moth, whitefly, and two-spotted spider mite are resistant to pyrethroids. Insecticide-like insecticides have developed resistance above the moderate level

Embodiment 1

[0051] Embodiment 1: 5% tofenpyram·beta-cypermethrin microemulsion

[0052] 98% Fenpyrad 2.55g

[0053]95% beta-cypermethrin technical 2.63g

[0054] Dimethylformamide (solvent) 10g

[0055] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0056] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0057] Water to make up to 100g.

[0058] The original drug, solvent and emulsifier are added together to dissolve into a uniform oil phase; under high-speed stirring, the oil phase is mixed with water to prepare a 5% pyrethrin-beta-cypermethrin microemulsion.

[0059] The compound agent of this example is applied to prevent and control cabbage pests (Plutella xylostella and aphids), and the dosage and control effect after 3 days are shown in Table 3. It can be seen from Table 3 that the amount of pyrenpyramid used in the field is relatively large, and the control effect on diamondback moth and aphids is not much different, between 80% and 85%, while th...

Embodiment 2

[0063] Example 2: 24% Fenpyramid · Beta-cypermethrin EC

[0064] 98% Fenpyran 20.41g

[0065] 95% beta-cypermethrin technical 4.21g

[0066] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0067] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0068] Xylene (solvent) was made up to 100 g.

[0069] Add the active ingredient, emulsifier and solubilizing agent into the mixing kettle according to the formula, and stir evenly to prepare 24% tonamiprole·beta-cypermethrin emulsifiable concentrate.

[0070] The compound agent of this example is applied to control cucumber pests (whitefly and Liriomyza sativae), and the control effect after 3 days of treatment is shown in Table 4. It can be seen from Table 4 that the control effect of tolfenpyrad against Liriomyza sativae is poor, that of beta-cypermethrin against whitefly is poor, and that the compound has good control effects on both kinds of pests.

[0071] Table 4, the test results of the compoun...

Embodiment 3

[0073] Embodiment 3: 22% Fenpyradradeltamethrin suspension concentrate

[0074] 98% Fenpyran 2.04g

[0075] 98.5% deltamethrin technical 20.30g

[0076] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5 grams

[0077] Xanthan gum (thickener) 1 g

[0078] Bentonite (thickener) 1g

[0079] Glycerin (antifreeze) 4 grams

[0080] Water to make up to 100g.

[0081] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the ratio of the formula, and ground to obtain a 22% Fenpyramid·Deltamethrin suspension concentrate.

[0082] The compound agent of this example is applied to prevent and control jujube pests (slug moths, Lygus aureus), and the control effect 1 day after the medicine is shown in Table 5. It can be seen from Table 5 that the control effect of the compound agent on jujube pests 1 day after the application is significantly higher than that of the two control agents, both re...

Abstract

The invention relates to a pesticide combination, which is characterized by comprising the active ingredients including tolfenpyrad (A) and a pyrethroid insecticide (B) which can be beta-cypermethrin,cypermethrin, beta-cyfluthrin, lambda-cyhalothrin, bifenthrin, fenpropathrin or deltamethrin. The mass ratio of A and B in the pesticide combination is 100:1 to 1:100. The pesticide combination of the invention is suitable for controlling various common pests and mites in agriculture.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing tolfenpyrad. Background technique [0002] Chemical control has always been the main means of pest control in agriculture. In agricultural production, usually several pests and mites occur simultaneously on one crop. Commonly used broad-spectrum insecticides and acaricides often have low activity, such as organophosphorus insecticides; while insecticides with high activity often have a narrow spectrum of control, such as benzoylurea insecticides are only effective on scales. Pteroptera pests are highly effective. [0003] Tolfenpyrad: English common name tolfenpyrad, chemical name 4-chloro-3-ethyl-1-methyl-N-[4-(p-tolyloxy)phenyl]pyrazole-5-amide, belongs to new type Pyrazole heterocyclic insecticide and acaricide. The main mechanism of action of tofenpyrad is to prevent the oxidative phosphorylation of insects, so that the adenosine diphosphate (A...
