Embodiment 1

[0018] Embodiment 1: Indoor toxicity test of methoxyfenozide and emamectin benzoate

[0019] Synergistic effect test of the combination of methoxyfenozide and emamectin benzoate. The test uses Spodoptera litura and Spodoptera litura as test objects, and the specific methods are as follows:

[0020] (1) Test drug:

[0021] 97.6% methoxyfenozide active ingredient American Dow AgroSciences

[0022] 90% Emamectin Benzoate Guangxi Antai Chemical Co., Ltd.

[0023] The original drug was prepared into the required test drug according to the conventional method.

[0024] (2) Test object:

[0025] Spodoptera litura: Collect egg masses in the field, hatch and raise them indoors to the second generation and third instar larvae;

[0026] Beet armyworm: Collect egg masses in the field, hatch and raise them indoors to the second generation and third instar larvae;

[0027] (3) Test method:

[0028] The test method refers to the "People's Republic of China Agricultural Industry Standa...

Embodiment 2

[0060] Example 2: 20.2% methoxyfenozide emamectin benzoate emulsion in water

[0061] 97.6% methoxyfenozide 20.49g

[0062] 90% Emamectin Benzoate 0.22g

[0063] N-methylpyrrolidone (solvent) 9.8 g

[0064] Dimethylformamide (solvent) 5.2 grams

[0065] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​4.5g

[0066] Calcium dodecylbenzenesulfonate (emulsifier) ​​3.6g

[0067] water to make up to 100g

[0068] Add the original drug, solvent, and emulsifier together to dissolve into a uniform oil phase; under high-speed stirring, mix the oil phase with the water phase to obtain 20.2% methoxyfenozide emamectin benzoic acid Salt water emulsion (ratio of 100:1).

[0069] The formula is diluted and sprayed with water at 3 g / ha of active ingredients, and is used to control Spodoptera litura on cabbage in Qingyuan, Guangdong (after testing, the resistance of Spodoptera litura to beta-cypermethrin in this area is 332.6 times, and the resistance to trichlorfon ...

Embodiment 3

[0072] Example 3: 4% methoxyfenozide emamectin benzoate suspension concentrate

[0073] 97.6% methoxyfenozide 2.05g

[0074] 90% Emamectin Benzoate 2.22g

[0075] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 4.7g

[0076] Xanthan gum (thickener) 0.6g

[0077] Bentonite (thickener) 2.2g

[0078] Glycerin (antifreeze) 3 grams

[0079] Water to make up to 100g.

[0080] Each component such as active ingredient, dispersant, wetting agent and water is mixed uniformly according to the ratio of formula, and is ground to obtain 4% methoxyfenozide emamectin benzoate suspension concentrate (proportioning is 1:1).

[0081] The formula is diluted and sprayed with water at 5 g / ha of active ingredients, and is used to control beet armyworm on kale. 3 days after the drug, the control effect was 95.8%. The 24% methoxyfenozide suspension concentrate and the 0.5% emamectin benzoate suspension concentrate were used in the same method and dosage,...

Abstract

The invention relates to a pesticide composition with a synergy effect. The pesticide composition is characterized in that effective components comprise methoxyfenozide and emamectin benzoate, wherein the mass ratio of the methoxyfenozide and the emamectin benzoate is 100:1-1:1. The composition has obvious synergy effect and can reduce the pesticide dosage and delay the resistance development. The composition can be used for preventing and controlling lepidoptera pests and is particularly suitable for preventing and controlling noctuidae pests, such as spodoptera exigua, prodenia litura, cotton bollworm, and the like.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a compound insecticidal composition containing methoxyfenozide and the application of the composition in preventing and controlling crop Lepidoptera pests. Background technique [0002] In the actual process of agricultural production, chemical control is an important means of preventing and controlling pests in agricultural production. In chemical control, the most likely problem is the emergence and development of resistance of bacteria and pests. [0003] Beet armyworm is one of the important pests in the production of vegetables and fruits all over the world. It has a wide distribution, miscellaneous feeding habits, and a large number of reproductions each time. Moreover, the outer skin of its larvae is smooth and difficult to adhere to medicines. There are many reports of its drug resistance in the whole country and even in the world. In my country, beet a...
