Problems solved by technology

Organophosphorus have a short duration of action, nicotine chloride has a poor lethal effect on adults, and pyrethroids have very low actual activity on flea beetle
Foliar application cannot take into account the larvae in the soil. Once the effective period of the drug expires, the adults will continue to emerge from the soil and continue to endanger crops.
Therefore, in order to prevent flea beetle, farmers have to frequently apply pesticides, which increases the cost, increases the residue, and increases the burden on the environment. However, the control effect is still not satisfactory.

Embodiment 1

[0053] Example 1: 11% Fenpyran·Butene Fipronil EC

[0054] 98% Fenpyran 10.20g

[0055] 96% Butene Fipronil Technical 1.04g

[0056] N-Methylpyrrolidone (solvent) 10g

[0057] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0058] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0059] Xylene (solvent) was made up to 100 g.

[0060] The active ingredient, emulsifier and solubilizing agent are sequentially added into the mixing tank according to the formula, and stirred evenly to prepare 11% pyrenpyrrole-butene fipronil emulsifiable concentrate.

[0061] See Table 3 for the amount and control effect of this example for the spraying and control of black-leaf cabbage flea beetle adults, and see Table 4 for the combined control effect on aphids. It can be seen from Table 3 that the control effect of the compound agent on the flea beetle is significantly higher than that of a single agent, and the control effect can still reach more than 80% 7 day...

Embodiment 2

[0066] Example 2: 30% Fenpyran-Butene Fipronil Microcapsule Suspension

[0067] 98% Fenpyran 5.10g

[0068] 96% butene fipronil technical 26.04g

[0069] Xylene (solvent) 10 grams

[0070] Urea (film former) 2 grams

[0071] Formaldehyde (film former) 3 grams

[0072] Tween-80 (emulsifier) ​​2g

[0073] Sodium polyacrylate (thickener) 2g

[0074] Sodium hydroxide (PH regulator) 0.5 g

[0075] water to make up to 100g

[0076] Add 2g of urea, 3g of formaldehyde and 25g of water into a three-necked flask equipped with a thermometer and a stirring device, raise the temperature to 80°C, and stir at a low speed for 1 hour to obtain an aqueous solution of urea-formaldehyde resin prepolymer. Dissolve the active ingredient in the solvent xylene at room temperature, stir evenly, add it to the aqueous solution of urea-formaldehyde resin prepolymer, and add 2g Tween-80, stir at high speed to form a stable O / W emulsion; reduce the speed to 600r / min, Polycondensation reaction; afte...

Embodiment 3

[0082] Example 3: 11% Fenpyran·Etpronil EC

[0083] 98% Fenpyran 10.20g

[0084] 94% ethiprole technical 1.06g

[0085] N-Methylpyrrolidone (solvent) 10g

[0086] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0087] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0088] Xylene (solvent) was made up to 100 g.

[0089] The active ingredient, emulsifier and solubilizing agent are sequentially added into the mixing tank according to the formula, and stirred evenly to obtain 11% pyrenpyrrole·ethiprole emulsifiable concentrate.

[0090] See Table 7 for the dosage and control effect of spraying and controlling adults of black-leaf cabbage flea beetle in this example. It can be seen from Table 7 that the control effect of the compound agent on flea beetle is significantly higher than that of the single agent, and the control effect can still reach 89.6% after 7 days.

[0091] Table 7, the control effect of the present embodiment compound agent fl...

Abstract

The invention relates to a pesticide composition which is characterized by comprising the effective components of tolfenpyrad and butene-fipronil or ethiprole. The pesticide composition has excellent control effect on flea beetles which are harmful to Cruciferae plants and also has good control effect on other injurious insects, such as aphids, diamond back moths, cabbage caterpillars, and the like on the Cruciferae plants.

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. Background technique [0002] Phyllotreta striolata (Fabricius): Phyllotreta striolata (Fabricius) mainly damages cruciferous vegetables such as cabbage, cauliflower, Chinese cabbage, Shanghai green, radish, turnip, and rapeseed. Cause harm and seriously affect the economic value of crops. The adult flea beetle is active and has a long life span of 50 days on average. The generations overlap, making it difficult to control, and the damage is increasing year by year. The control of flea beetle has always relied on chemical control, and the control of adult insects is the main method. At present, the agents registered for the control of flea beetle adults mainly include organophosphate dichlorvos, chlorpyrifos, malathion, nicotinoid thiamethoxam, acetamiprid, pyrethroid cypermethrin, and their compou...
