Embodiment 1

[0054] Example 1: 10% Fenpyran·Indoxacarb EC

[0055] 98% Fenpyran 5.10g

[0056] 94% Indoxacarb Technical 5.31g

[0057] N-Methylpyrrolidone (solvent) 10g

[0058] Dimethylformamide (solvent) 10 grams

[0059] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0060] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0061] Xylene (solvent) was made up to 100 g.

[0062] The active ingredient, emulsifier and solubilizing agent are sequentially added into the mixing kettle according to the formula, and stirred evenly to prepare 10% pyrenpyramid·indoxacarb EC.

[0063] The amount and control effect of this embodiment applied to the control of soybean Spodoptera litura are shown in Table 3. It can be seen from Table 3 that the control effect of the compound agent on Spodoptera litura reached more than 90%, better than the two single agents, indicating that the compound agent has high efficiency and long-lasting effect on Spodoptera litura.

Embodiment 2

[0067] Example 2: 22% Fenpyran·Indoxacarb Suspension Concentrate

[0068] 98% Fenpyran 20.41g

[0069] 94% indoxacarb technical 2.13g

[0070] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5 grams

[0071] Xanthan gum (thickener) 1 g

[0072] Bentonite (thickener) 1g

[0073] Glycerin (antifreeze) 4 grams

[0074] Water to make up to 100g.

[0075] 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% tonfenpyramide·indoxacarb suspension.

[0076] This example is applied to the control of rice leaf roller, and the dosage and control effect are shown in Table 4. It can be seen from Table 4 that the control effect of the compound agent on rice leaf roller is higher than that of the two single agents, and the dosage is less than that of the single agent of pyrenpyramid.

[0077] Table 4, the control effect of the compound agent...

Embodiment 3

[0079] Example 3: 20.4% Fenpyran·Indoxacarb Water Emulsion

[0080] 98% Fenpyran 20.41g

[0081] 94% Indoxacarb Technical 0.43g

[0082] Xylene (solvent) 10 grams

[0083] Tristyrylphenol ethoxylate phosphate (emulsifier) ​​4 g

[0084] Propylene glycol (antifreeze) 4 grams

[0085] Polydimethylsiloxane (defoamer) 0.3g

[0086] water to 100g

[0087] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix antifreeze and defoamer to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain 20.4% azole Anthramid Indoxacarb Water Emulsion.

[0088] This example is applied to the prevention and treatment of bean pod borer, and the dosage and control effect are shown in Table 5. It can be seen from Table 5 that the compound agent has better quick-acting and persistent effect than single agent in controlling pod borer.

[0089] Table 5, the control effect of the present embodiment compound agent ...

Abstract

The invention discloses a synergistic pesticide composition which is characterized in that the effective components thereof are tolfenpyrad and indoxacarb. The pesticide composition has obviously synergistic effect on the agricultural lepidoptera pests, particularly has excellent prevention and treatment effect on plutella xylostella, and can delay the development of pest resistance to drug.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing indoxacarb and its application in controlling crop Lepidoptera pests. Background technique [0002] The vast majority of Lepidoptera pests harm plants with their larvae feeding on leaves, stamens, buds, fruits, and branches of plants. Most of these pests are gluttonous. In addition, they have strong reproductive ability. Once a large-scale outbreak occurs, they will often cause devastating disasters to crops. The diamondback moth Plutella xylostella (Linnaeus) is one of the most important Lepidoptera pests that harm cruciferous vegetables worldwide. . Its reproduction speed is fast, generation overlap is serious, and resistance develops rapidly. It has become one of the most resistant insect pests. Various types of insecticides, such as growth regulators and biological agents Bt, have produced varying degrees of resistance, directly leading to a sig...
