Embodiment 1

[0065] A microemulsion mixed with emamectin benzoate and beta-cyfluthrin, consisting of the active ingredients of the following raw materials: 0.25 kg of emamectin benzoate, 2.5 kg of beta-cyfluthrin, industrial 10 kg of ethanol, 5 kg of calcium alkylbenzene sulfonate, 5 kg of nonylphenol polyoxyethylene ether, and 77.25 kg of tap water.

[0066] The preparation method is: mix and stir emamectin benzoate, beta-cyfluthrin, ethanol and surfactant evenly to form a transparent oil phase, slowly add water under stirring to form a water-in-oil emulsion, Stir and heat to 50°C to rapidly invert the phase into an oil-in-water type, and then use a high-speed shearing machine to emulsify for 30 minutes to make a microemulsion.

[0067] Dilute this product 4,000 times with clean water at normal temperature and spray it on the leaves of apple trees, and the control effect on peach borer can reach 99.3%.

Embodiment 2

[0069] A microemulsion mixed with emamectin benzoate and beta-cyfluthrin, composed of the active ingredients of the following raw materials: 0.18 kg of emamectin benzoate, 2.5 kg of beta-cyfluthrin, industrial 9 kg of ethanol, 6 kg of calcium alkylbenzene sulfonate, 3 kg of sodium dodecylbenzene sulfonate, and 79.32 kg of tap water.

[0070] The preparation method is the same as in Example 1.

[0071] Dilute this product 3000 times with clean water at normal temperature and spray it on the leaves of vegetables. The control effect on diamondback moth, beet armyworm and cabbage caterpillar reaches 92.4%.

Embodiment 3

[0073] A microemulsion mixed with emamectin benzoate and beta-cyfluthrin, consisting of the active ingredients of the following raw materials: 0.25 kg of emamectin benzoate, 3.6 kg of beta-cyfluthrin, industrial 12 kg of ethanol, 6 kg of alkylphenol polyoxyethylene ether, 6 kg of sodium dodecylbenzenesulfonate, and 72.15 kg of tap water.

[0074] The preparation method is the same as in Example 1.

[0075] Dilute this product 4,000 times with clean water at normal temperature and spray it on the leaves of apple trees, and the control effect on peach borer can reach 100%.

Abstract

The invention discloses emamectin benzoate and efficient cyfluthrin pesticide mixture preparation which is composed of 0.13-0.28% of emamectin benzoate benzoate, 1.3-3.9% of high-efficient cyfluthrin, 6-15% of surfactant and the balance dispersed medium. The preparation comprises two dosage forms of microemulsion and wettable powder. The preparation is suitable for fruit trees and brassicaceous vegetable, and is suitable for killing apple tree carposina niponensis walsingham, Grapholitha molesta Busck, plutella xylostella, beet armyworm, cabbage caterpillar and the like. The using method is as follows: adopting pure water at normal temperature to dilute for 3000-5000 times for carrying out foliar spraying; field tests prove that the control efficiency on the above pests reaches above 90%, and the control efficiency on the carposina niponensis walsingham reaches above 95%. The invention uses tap water as well as solid supports, such as bentonite, kaolin, kieselguhr and the like to replace dimethyl benzene commonly adopted in the prior art, thus lowering production cost, lightening the environment pollution to poisonous reagent, bringing convenience for improving agricultural product quality and ensuring agricultural product quality safety.

Description

technical field [0001] The invention relates to a high-efficiency, low-toxicity broad-spectrum insecticide emamectin benzoate and high-efficiency cyfluthrin as active ingredients mixed pesticide preparation, which belongs to the field of pesticide formulation processing. Background technique [0002] Chemical pesticides are still one of the indispensable measures to control pests and diseases in agricultural production. However, due to the long-term use of a single dosage form of chemical insecticides, pests are prone to develop resistance. In order to achieve the effect of control, we have to increase the amount of pesticides used and the frequency of application or use more toxic pesticides, which not only increases the cost of planting The economic burden of households has also seriously affected the safety of agricultural products and aggravated the pollution to the environment. Food quality and safety caused by pesticide residues has become the focus and hot issue of w...
