Embodiment approach

[0013] The simple embodiment of the pesticide dosage form that composition of the present invention can be made is as follows:

[0014] In one of the technical solutions of the present invention, the insecticidal composition is an aqueous solution, and the weight percentage of the components is:

[0015]

[0016]

[0017] The specific production steps of the water preparation are as follows: first, add the original drug matrine, nitenpyram, emulsifier, penetrant, and antifreeze, fill in the remaining water, and start stirring at a temperature of 30°C Ultrasonic dispersion for 30 minutes, all dissolved, can be made into the water agent of the composition of the present invention, and the product is a transparent liquid.

[0018] In the second technical solution of the present invention, the insecticidal composition is an emulsifiable concentrate preparation, and the mass percentage of the components is:

[0019]

[0020] The specific production steps of the emulsifiab...

[0045] (1) Test drug

[0046] 10% matrine technical, Chifeng Zhongnongda Biochemical Technology Co., Ltd.; 95% nitenpyram technical, Jiangsu Nantong Jiangshan Pesticide Chemical Co., Ltd.

[0047] Dissolve the original drug with acetone first, and mix the appropriate amount of the two original drugs into 5 different ratios according to the results of the preliminary experiment, and then use acetone to dilute each treatment into 5 series of concentration gradients for use.

[0048] (2) Test target

[0049] Rice planthopper. The brown planthopper was used as the test object. The insect species were taken from the paddy fields of Dalu Village, Zhaodian Town, Gaoqing County. They were artificially raised for multiple generations in the insect culture room, and the healthy and consistent 4-5 instar nymphs were selected for future use.

[0050] (3) Test method

[0051] The spot method recommended by NY / T1154.1-2006 was used for determination. Clean the micro-dropper with solvent...

[0071] (2) Test target

[0072] Plutella xylostella reared for generations indoors, indoor conditions: temperature (26±2)°C, relative humidity 70%±5%, photoperiod 16 / 8h (L / D).

[0073] Experimental method is the same as activity determination example 1

[0074] (3) Toxicity test results and analysis:

[0075] Table 2 Indoor determination results of matrine and nitenpyram on diamondback moth

[0076]

[0077] 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 matrine: nitenpyram 0.3:12 is the most obvious , and the co-toxicity coefficient was 195.51. The test results showed that matrine and nitenpyram both had higher ...

Abstract

The invention relates to an insecticidal composition in the field of pesticide formulation. The insecticidal composition comprises active ingredients consisting of matrine and nitenpyram. The ratio of the percentage by weight of the two active ingredients is (0.01-15):(80-1), preferably (5-0.1):(5-50). The total mass percentage content of the active ingredients in the insecticidal composition is 1-90%, preferably 5-50%; and others are allowable and acceptable auxiliary ingredients in pesticide. The insecticidal composition can be prepared into aqueous solution agents, missible oil, suspending agents, soluble agents, wettable powder and water-dispersible granules. The insecticidal composition by taking the matrine and the nitenpyram as the active ingredients is mainly used for preventing and controlling pests on rice, cotton, wheat and cruciferous vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a dual compound insecticidal composition with matrine and nitenpyram as active ingredients. Background technique [0002] Matrine is extracted from the roots, stems, leaves, and fruits of the Chinese herbal medicine Sophora flavescens by ethanol and other organic solvents. It is an alkaloid, usually total alkaloids of matrine. Various alkaloids such as sophocarpine, oxysophocarpine, and sophoridine, among which matrine and oxymatrine have the highest content. Matrine is a natural plant pesticide with stomach toxicity and contact killing effect. Matrine has low toxicity to humans and animals. It is a broad-spectrum insecticide and can be used to control rice planthoppers, rice stem borers, stem borers, and cruciferous vegetables. Aphids, cabbage caterpillars, diamondback moths, chive maggots, tea tree caterpillars, tea inchworms, tobacco budworms, aphids and other h...
