Embodiment 1

[0014] Biological Example 1: Beet Spodoptera

[0015] Beet armyworm collected in the field was used in the experiment, which was used for the experiment after two generations of breeding. The specific method is as follows:

[0016] Leaf disc preparation: select clean bracts, wash and dry them, and use a puncher to make leaf discs for later use.

[0017] Pharmaceutical preparation: The original drug for the test is provided by the manufacturer, and the required preparation is made by our company's product development center. Before the test, different concentration gradients were prepared according to different proportioning schemes, with 6 concentrations for each proportioning.

[0018] Dipping: Use tweezers to pick up the leaf discs and dip them in the liquid medicine for 5 seconds, take them out and dry them on absorbent paper, and put them in a 24-well plate after air-drying naturally, with 2 pieces per well. A total of 3 plates were placed for each concentration treatme...

Embodiment 2

[0032] Biological Example 2: Tetranychus cinnabarinus

[0033] Insect test: Tetranychus cinnabarinus raised on broad bean seedlings indoors all the year round. Before the test, stick double-sided tape on one end of the glass slide, and use a brush to select the multiplied adult mites of the same age and paste them on the tape. About 50 slices are placed in a 9cm petri dish covered with filter paper for moisturizing. After 2 hours, the microscopic examination was carried out, and the dead worms were discarded.

[0034] Pharmaceutical preparation: The original drug for the test is provided by the manufacturer, and the required preparation is made by our company's product development center. Before the test, different concentration gradients were prepared according to different proportioning schemes, with 6 concentrations for each proportioning.

[0035] Immersion: Start with a low concentration, pick up the glass slide with tweezers, immerse the end with the mite in the soluti...

Embodiment 3

[0042] Biological Example 3: Rice leaf roller

[0043] Test insects: Cut the fresh buds of the rice leaf roller collected in the field to about 8 cm in length, put them into disposable plastic cups, and put 30 to 40 buds in each plastic cup.

[0044] Pharmaceutical preparation: The original drug for the test is provided by the manufacturer, and the required preparation is made by our company's product development center. Before the test, different concentration gradients were prepared according to different proportioning schemes, with 6 concentrations for each proportioning.

[0045] Spray: use a POTT spray tower to spray at a pressure of 50PSI, and spray 2ml each time. The spray starts from low concentration, and the blank control sprays the same amount of water. After spraying, cover the roll with paper, tie it with a rubber band, and put it in the insect culture room (25±1°C, 12H / 12H).

[0046] Survey statistics: Check the number of dead insects after 24 hours of treatme...

Abstract

The invention relates to an insecticidal composition containing oxymatrine and benzoylurea components. The mass ratio of the oxymatrine to benzoylurea insecticides is (1-40): (40-1). The benzoylurea insecticides are one or more of hexaflumuron, flufenoxuron, chlorfluazuron, lufenuron, novaluron, chlorbenzuron, diflubenzuron and teflubenzuron. The insecticidal composition can be used for preventing beet armyworms, rice leaf folders, cotton bollworms, plutella xylostellas, cabbage caterpillars, prodenia litura, apple skin worms, whiteflies and red spider mites.

Description

technical field [0001] The invention relates to an insecticidal composition and its use, in particular to a compound composition containing oxymatrine and benzoylurea insecticidal ingredients. The invention can be used for controlling pests such as beet armyworm, rice leaf roller, cotton bollworm, diamondback moth, cabbage caterpillar, Spodoptera litura, apple leaf roller, whitefly, red spider and the like. Background technique [0002] In the past few decades, insecticides such as organophosphorus, carbamate, and pyrethroids have played a very important role in the prevention and control of agricultural production and income. Pests have developed severe resistance to these insecticides; meanwhile, these traditional insecticides have brought serious harm to the natural enemies of pests and polluted the environment. Therefore, developing insecticides with high selectivity, low toxicity and environmental friendliness has become the trend of pesticide development in the future...
