Problems solved by technology

Following this line of thought, the R&D personnel of our company have conducted long-term research in the field of pesticide compounding, and found that the new pesticide thiofluoroxime ether can effectively make up for the disadvantages of carbamate pesticides, and compounding the two can produce good synergy It can greatly reduce the dosage of pesticides, and further expand the insecticidal spectrum. It has good quick-acting and long-lasting effects, and is easy to decompose with low residues, which is environmentally friendly and efficient. So far, no combination of thiofluoroxime and carbamate pesticides Mixed related reports

example 1

[0050] (1) Test drug

[0051] 94% of thiofluoroxime technical material and 98% of isoprocarb technical material were provided by Qingdao Hailier Pharmaceutical Co., Ltd.

[0052] (2) Source of tested insects

[0053] The tea leafhopper was collected from Chashan, Jiangxi. During the experiment, the larvae of the tea leafhopper with the same individual size were selected for testing.

[0054] (3) single-dose determination method

[0055] The two groups of original drugs were dissolved in a small amount of acetone by worm soaking method, and then diluted with 0.1% Tween aqueous solution to form 5 concentrated solutions with equal difference, which were diluted in beakers for later use, and clear water was used as a control.

[0056] Soak green leafhopper larvae of the same size in the medicinal solution of the insect cage for 5 seconds, absorb the excess medicinal solution and place it in a petri dish with a diameter of 9 cm. The dish is covered with fresh tea tree leaves. 10...

[0073] (1) Experimental test agent

[0074] 94% of thiofluoroxime ether and 98% of methomyl are provided by Qingdao Hailier Pharmaceutical Group.

[0075] (2) Test target

[0076] The third-instar larvae of the cabbage cabbage caterpillar were raised continuously for 10 generations indoors with radish seedlings, the temperature was (25±2)°C, the relative humidity was 50%±4%, and the photoperiod was 14 / 10h (L / D).

[0077] Experimental method is the same as activity determination example 1

[0084] (1) Test drug

[0085] 94% thiofluoroxime technical, 95% thiodicarb technical, all of which are provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0086] (2) Test target

[0087] Beet armyworm raised for generations indoors, indoor conditions: temperature (28±2)°C. The relative humidity is 70%±5%, and the photoperiod is 16 / 8h (L / D).

[0088] Experimental method is the same as activity determination example 1

[0091]

[0092] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, among which the synergistic effect of thiofluoroxime ether: thiodicarb at 7:11 is the most obvious , and the co-toxicity coefficient was 158.68. The test results show that under indoor conditions, both thioflu...

Abstract

The invention relates to an insecticidal composition, which belongs to the pesticide complex field. The effective components are sufluoxime and carbamates pesticides, wherein the weight ratio of two effective components is 1 - 80: 80 - 1, preferably the weight ratio is 3 - 50: 60 - 5; the total mass percentage content of the active ingredient in the insecticidal composition is 1% to 90%, preferably the total mass percentage content is 5% to 60%, and the balance is other pesticides acceptable auxiliary materials, aqueous emulsions, micron emulsions, missible oil, pulvis, suspending agents, water dispersible powder and water dispersion granules can be prepared by a known method; sufluoxime and carbamates pesticides are taken as active ingredients for preventing and controlling tea pests, citrus moths and vegetable insects.

Description

technical field [0001] The invention relates to the field of compounding of pesticides and insecticides, in particular to an insecticidal composition and a preparation method thereof for dual compounding with thiofluoroxime ether and carbamate compounds as active ingredients. Background technique [0002] Thiofluoroxime ether is a new non-ester pyrethroid insecticide with independent intellectual property rights independently designed and synthesized by Hunan Research Institute of Chemical Industry in Hunan Base of National Southern Pesticide Innovation Center in 2002.
