Embodiment 1

[0020] Embodiment 1: Composite medicament is to indoor toxicity determination of diamondback moth

[0021] For testing pests: cabbage diamondback moth, choose the same size, healthy 3rd instar larvae as test insects;

[0022] Drugs to be tested: bromifranil technical, cyfluthrin technical; purchased from the market;

[0023] Test method: Leaf soaking method is adopted. On the basis of the pre-test, 7 concentration gradients were set for each agent, water was used as the blank control, and 4 repetitions were performed, with 24 3rd instar larvae of Plutella xylostella for each repetition. Punch the clean cabbage leaves into discs with a diameter of about 2 cm, immerse the leaves in the corresponding chemical treatment concentration, take them out after 10 seconds, dry them naturally and place them in a 12-well plate, put one piece in each hole and connect them. Enter 2 test insects that were starved for 4 hours, and cover a layer of paper above the 12-well plate (to prevent th...

Embodiment 2

[0029] Embodiment 2: the formulation of compound medicament

[0030] 12% bromide chlorofluorocyanide suspension concentrate. Contains the following ingredients in weight percentage:

[0031] Bromflubendiamide 2%, Cyfluthrin 10%, Dispersant NNO 3%, Sodium Lignosulfonate 2%, SP-SC 31%, Magnesium Aluminum Silicate 1.5%, Xanthan Gum 1%, Propylene Glycol 1%, Silicone defoamer 2%, deionized water to make up 100%.

[0032] 22% bromide chlorofluorocyanide suspension concentrate. Contains the following ingredients in weight percentage:

[0033] Bromflubendiamide 2%, Cyfluthrin 20%, Dispersant NNO 4%, Sodium Lignosulfonate 1%, SP-SC 32%, Magnesium Aluminum Silicate 2%, Xanthan Gum 0.5%, Propylene Glycol 2%, Silicone defoamer 1%, deionized water make up 100%.

[0034] 33% bromide chlorinated wettable powder. Contains the following ingredients in weight percentage:

[0035] Bromflubendiamide 3%, cyfluthrin 30%, sodium dodecylbenzene sulfonate 4%, sodium lignosulfonate 3%, white car...

Embodiment 3

[0042] Example 3: Field Control Efficiency Test of Compound Agents for Plutella xylostella

[0043] Test method: 6 treatments were set up in the test setting, and clear water was used as the blank control. Each treatment was repeated 3 times, randomly arranged, the area of ​​the plot was about 25m2, the water consumption was 40kg / mu, and the pesticide was applied before the 3rd instar of Plutella xylostella larvae. The five-point sampling method was adopted before spraying and 7 days after spraying, and the number of insect populations of 5 plants was investigated at each point, and the rate of insect population decline and corrected control effect were calculated.

[0044] Result of the test: as can be seen from Table 2, compared with other preparations of the same consumption, 12% bromotilicon · chlorofluorochlorosuspension concentrate prepared by the present invention, 22% bromotilicon · cyanofluorinated chloride suspension concentrate have higher for Plutella xylostella ca...

Abstract

The invention provides an insecticidal composition containing broflanilide and cyfluthrin, wherein the active components of the insecticidal composition comprise broflanilide and cyfluthrin, and a mass ratio of broflanilide to cyfluthrin is (1:20)-(20:1). According to the invention, the insecticidal composition can be used for controlling crop pests, wherein the pests comprise coleoptera, hemiptera, homoptera and lepidoptera pests, and is especially used for preventing and treating plutella xylostella or cabbage caterpillars.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition comprising flubendiamide and cyfluthrin and its application Background technique [0002] Bromflubendiamide is a meta-diamide (m-formamidobenzamide) insecticide jointly developed by Mitsui Chemicals and BASF. Its mechanism of action is obviously different from that of existing phthalides such as chlorantraniliprole, which is an allosteric modulator of gamma-aminobutyric acid (GABA)-gated chloride channels, inhibiting the neurotransmission of target insects, Causing convulsions and ultimately death is the only drug with this mechanism of action at present. [0003] Cyfluthrin has contact and stomach poisoning effects with a long duration of action. It is suitable for killing insects on cotton, fruit trees, vegetables, tea trees, tobacco, soybeans and other plants. It can effectively control the pests of Coleoptera, Hemiptera, Homoptera and Lepidoptera on ce...
