Embodiment 1

[0055] 15% spirodiclofen·acetamiprid EC

[0056] 5 grams of spirodiclofen, 10 grams of acetamiprid, 15 grams of dimethylformamide (cosolvent), 6 grams of calcium dodecylbenzenesulfonate (emulsifier), and xylene (solvent) to make up to 100 grams.

[0057] The active ingredients, emulsifiers and solubilizers are sequentially added to the mixing kettle according to the formula, and stirred evenly to prepare 15% spirodiclofen·acetamiprid EC.

[0058] The mixed formulation of this embodiment is used for the control of Bemisia tabaci from cotton. 15% spirodiclofen·acetamiprid EC is diluted and sprayed with water at an effective ingredient dosage of 30 g / ha, and the control effect is 94.6% after 3 days. The control agent 15% spirodiclofen EC and 3% acetamiprid EC According to the same dosage and method, the preventive effects of 3 days after the medicine were 70.2% and 83.8%.

Embodiment 2

[0060] 22% Spirodicodifen·acetamiprid suspension

[0061] 20 grams of spirodiclofen, 2 grams of acetamiprid, 5 grams of sodium methyl naphthalene sulfonate formaldehyde condensate (wetting and dispersing agent), 1 gram of xanthan gum (thickener), glycerol (antifreeze) 3 Make up to 100 grams with grams and water.

[0062] The active ingredients, dispersant, wetting agent and water are mixed uniformly according to the formula, and after grinding, 22% spirodiclofen·acetamiprid suspension is obtained.

[0063] The mixed formulation of this example is used to control the diamondback moth. 22% spirodiclofen·acetamiprid suspension is sprayed according to the effective ingredient dosage of 60 g / ha diluted with water, and the control effects are 93.6% and 84.5% respectively on 3 and 15 days after administration; the control agent 15% spirodiclofen The emulsifiable concentrate was used in the same dosage and method, and the control effects were 75.7% and 68.5% at 3 and 15 days after the drug...

Embodiment 3

[0065] 21% Spirodicodifen·Imidacloprid EC

[0066] 20 grams of spirodiclofen, 1 gram of imidacloprid, 10 grams of dimethylformamide (cosolvent), 5 grams of calcium dodecylbenzene sulfonate (emulsifier), and xylene (solvent) make up to 100 grams.

[0067] The active ingredients, emulsifiers and solubilizers are sequentially added to the mixing kettle according to the formula, and stirred evenly to obtain 21% Spirodicodifen·Imidacloprid EC.

[0068] The mixed formulation of this embodiment is used to control cabbage aphids. 21% spirodiclofen·Imidacloprid EC is sprayed according to the active ingredient weekly amount of 30 g / ha diluted with water, and the control effect is 90.6% after 5 days; 15% spirodiclofen and 5% imidacloprid EC are in the same dosage and Using the method, the control effects were 74.5% and 81.2% after 5 days of medicine.

Abstract

The invention discloses a mixed pesticide preparation containing anabasine, which takes spirodiclofen and anabasine as active matters, wherein the anabasine may be imidacloprid, acetamiprid, nitenpyram, thiamethoxam, clothianidin or thiacloprid. The mixed pesticide preparation may be in form of missible oil, microemulsion, water emulsion, water dispersible granules, wettable powder or suspension. After being mixed, the pesticide helps to delay the extension of the resistance to the anabasine active matter and prolong the service life of the medicine; and the antibacterial spectrum of the anabasine active matter is broadened.

Description

Technical field [0001] The invention belongs to pesticide compounding and a preparation method thereof, in particular to a compound pesticide preparation containing neonicotines. Background technique [0002] Neonicotinoids are a class of highly effective insecticides. Their mechanism of action is to act on nicotinic acetylcholine receptors and interfere with the normal conduction of the insect's nervous system, resulting in insect paralysis and death. Common neonicotinoids are: imidacloprid, acetamiprid, nitenpyram, thiamethoxam, clothianidin, thiacloprid, etc. The neonicotinoids have low toxicity to mammals, are safe to the environment, and have high insecticidal activity. However, neonicotinoids also have some shortcomings: the insecticidal spectrum is not broad, and the risk of resistance rises quickly. [0003] Spirodiclofen is a new pesticide modified on the basis of spirodiclofen. The product has a unique mechanism of action. In addition to the characteristics of long last...
