Embodiment 1

[0021] Example 1: Compound toxicity test of metaflumizone, chlorpyrifos and phoxim

[0022] 1. Determination of the toxicity of metaflumizone, chlorpyrifos and different ratios to the rice leaf roller

[0023] The rice leaf roller pupae collected from the field were reared indoors for three generations, and the third instar larvae with uniform growth were selected as the test insects. Using the method of soaking leaves and inoculating insects, the test agent was mixed with acetone and 10% Tuwen-80 to make a certain concentration of mother liquor, and then diluted with clear water to 5 gradient concentrations for use, and clear water was used as a control. Take fresh rice leaves and cut them into leaf segments about 40mm long, soak the cut leaves in the prepared test drug solution for 10 seconds, take them out and let them dry naturally, and put them into a petri dish (φ120mm) with filter paper in advance middle. Then the 3rd instar larvae of Leaf Roller Borer were inserted i...

Embodiment 2

[0058] Example 2: Preparation method of 81% metaflumizone·pyridazinphos EC and field test of medicament

[0059] Metaflumizone 80%

[0060] Pyridazinphos 1%

[0061] Nongru 600# (emulsifier) ​​7%

[0062] Xylene (solvent) balance

[0063] According to the formula requirements, mix and stir metaflumizone, pyridazinphos, emulsifier, and part of the solvent in the preparation kettle. After completely dissolving, add the remaining solvent slowly, and get a uniform oil phase after fully stirring. Promptly make the pesticidal composition emulsifiable concentrate of the present invention.

[0064] The preparation of this example is used to control rice leaf rollers. Control by spraying. When the pesticide was applied, the rice was at the initial heading stage, and the rice leaf rollers in the field were mostly 2nd and 3rd instar larvae, and the weather was fine. A total of 5 treatments were set up in the experiment, and each treatment was repeated 4 times. Investigate the base...

Embodiment 3

[0069] Example 3: Preparation method of 30% metaflumizone·diazinon suspension concentrate and field test of medicament

[0070] Metaflumizone 25%

[0071] Diazinon 5%

[0072] Sodium dodecylbenzenesulfonate (wetting agent) 1%

[0073] Calcium lignosulfonate (dispersant) 2%

[0074] Methylcellulose (viscosity enhancer) 2%

[0075] Bentonite (stabilizer) 3%

[0076] Ethylene glycol (antifreeze) 1%

[0077] Deionized water (solvent) balance

[0078] According to the formula requirements, in the dispersing tank equipped with a high-speed agitator, disperse the original drug and the dispersant in water, and coarsely pulverize the original drug; continuously send the coarsely pulverized solution into the sand mill with a quantitative pump, Carry out fine pulverization; the solution separated from the medium and discharged is sent to the final mixing tank, and the thickener solution prepared in addition is added to the final mixing tank, and mixed evenly with the pulverized sol...

Abstract

The invention discloses an insecticidal composition containing metaflumizone, which comprises effective constituents of a component A and a component B, wherein the component A is the metaflumizone, and the component B is any one of chlorphrifos, phoxim, triazophos, profenofos, diazinon, cidial and pyridaphethione; the component A and the component B have the weight ratio of 80:1-1:80; and the accumulated weight percent of the effective constituents is 1-80 percent. The insecticidal composition has the advantages of synergistic effect and obviously improved pest control effect and can reduce drug amount and delay the development of the drug resistance of pests. The insecticidal composition can control the pests on crops and particularly be applied to control cnaphalocrocis medinalis, riceborer, cotton bollworms, spodoptera litura and spodoptera exigua.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing metaflumizone as an active ingredient and its application in preventing and controlling crop pests. Background technique [0002] Metaflumizone (metaflumizone) belongs to semicarbazone insecticides, is a highly selective insecticide, insecticidal activity is mainly manifested in Lepidoptera pests and some Coleoptera pests. The mode of insecticidal action is mainly stomach poisoning, with small contact action, strong permeability, and good resistance to rain erosion. The mechanism of insecticidal action is unique, acting on the sodium ion channel on the axon membrane of pest neurons. No cross-resistance with organophosphate insecticides. However, the insecticidal spectrum of metaflumizone is not wide enough, and the death of pests is slow. At present, it cannot be manufactured in China, and the cost of use is very high. [0003] Chlorpyrifos,...
