Embodiment 1

[0067] Example 1: 5% Fenpyran·Lufenuron microemulsion

[0068] 98% Fenpyrad 2.55g

[0069] 96% Lufenuron Technical 2.60g

[0070] N-Methylpyrrolidone (solvent) 10g

[0071] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0072] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0073] Water to make up to 100g.

[0074] 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 the water phase to prepare a 5% tonamiprole-lufenuron microemulsion.

[0075] The compound agent of this embodiment is sprayed at the following concentration to prevent and control cotton bollworm (this population shows moderate resistance to lambda-cyhalothrin), and the control effect is shown in Table 5. It can be seen from Table 5 that the control effect of the compound agent after 1 day is much higher than that of a single agent of lufenuron, indicating that the quick effect...

Embodiment 2

[0078] Example 2: 22% Fenpyran·Lufenuron EC

[0079] 98% Fenpyran 2.04g

[0080] 96% lufenuron technical 20.41g

[0081] N-Methylpyrrolidone (solvent) 10g

[0082] Dimethylformamide (solvent) 10 grams

[0083] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0084] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0085] Xylene (solvent) was made up to 100 g.

[0086] The active ingredient, emulsifier and solubilizer are sequentially added into the mixing tank according to the ratio of the formula, and stirred evenly to obtain 22% tonfenpyradrolufenuron emulsifiable concentrate.

[0087] This implements compound agent example according to 4400 times of spraying control apple tree leaf tortrix, 1 day after the medicine, the control effect of 3 days after the medicine is respectively 88.3% and 90.1%; The control effects of 1 day and 3 days after application were 78.1% and 82.9% respectively; 5% lufenuron EC was diluted and sprayed by 1000 times,...

Embodiment 3

[0088] Example 3: 33% Fenpyran·Lufenuron Suspension Concentrate

[0089] 98% Fenpyran 30.61g

[0090] 96% Lufenuron Technical 3.13g

[0091] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5 grams

[0092] Xanthan gum (thickener) 1 g

[0093] Bentonite (thickener) 1g

[0094] Glycerin (antifreeze) 4 grams

[0095] Water to make up to 100g.

[0096] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the proportion of the formula, and ground to obtain a 33% tonfenpyram-lufenuron suspension concentrate.

[0097] The compound agent of this embodiment is sprayed to prevent and control Plutella xylostella at an active ingredient dosage of 3 g / mu, and the control effects of 1 day and 3 days after the drug are respectively 80.4% and 92.3%; gram / mu spray dilution spray, the control effect of 1 day and 3 days after the drug is 74.3% and 85.3% respectively; The control effects were 41.6...

Abstract

The invention relates to a pesticide composition. The composition is characterized by comprising tolfenpyrad (A) and another benzoylphenylurea pesticide active constituent (B), wherein the (B) can belufenuron, hexaflumuron, ehlorfluazuron, flufenoxuron or chlorbenzuron. The invention also relates to an application of the pesticide composition in preventing and curing pests of crops.

Description

technical field [0001] The invention relates to a pesticide composition and its application, in particular to a pesticide composition containing tolfenpyrad and its application for controlling crop pests. Background technique [0002] Benzoylurea chitin synthesis inhibitors can inhibit the activity of insect chitin synthase, hinder chitin synthesis, hinder molt and pupation of insects, slow down activities, reduce feeding, and eventually die. Benzoylurea-based chitin synthesis inhibitors are highly effective against Lepidoptera larvae, have a long duration of action, and are safe for higher animals. They are in line with the development trend of green pesticides and have broad application prospects. Lufenuron, hexaflumuron, chlorfluazuron, flufenoxuron and chlorbenzuron are five important benzoylurea chitin synthesis inhibitors Variety. The disadvantage of benzoylurea-based chitin synthesis inhibitors is that they act slowly, and generally reach the peak of death 3 to 7 da...
