example 1

[0054] Biological assay example 1: Toxicity determination of pirimiphos-methyl and dinotefuran compound to German cockroaches

[0055] The purpose of the experiment: taking the male adults of Blattella germanica reared in the laboratory as biological targets, to determine the toxicity of each single dose and the mixture of pirimiphos-methyl and dinotefuran to Blattella germanica, and to calculate the co-toxicity coefficient of the mixture , to determine the strength of the synergistic effect.

[0056] Test method: micro-drop method 1. Drug solution configuration Use 1 / 10,000 electronic balance to accurately weigh the required drug, use acetone as solvent to prepare a certain concentration of mother liquor according to W / V, and then configure 5-7 according to equal ratio or grade difference A concentration is available for use. 2. After anesthetizing the test insects with ether, arrange them in a group of 30 in a supine position, and use acetone as a control, and then use a sm...

[0064] Biological Assay Example 2: Toxicity determination of pirimiphos-methyl and pichridam to larvae of Culex palustris

[0065] The purpose of the experiment: taking the larvae of Culex palustris bred in the laboratory as the bioassay target, to determine the toxicity of each single agent and the mixture of pirimiphos-methyl and pichridam to the larvae of Culex palustris, and to calculate the co-toxicity coefficient of the mixture, Determine the strength of synergy.

[0066] Test method: Liquid immersion method: LC50 is obtained by immersing mosquito larvae in different liquids for 24 hours to obtain LC50, and the larval killing rate of each treatment is measured, and the co-toxicity coefficient of the mixture is calculated. Comprehensively analyze the relevant indicators of each treatment, and select the ratio with strong synergistic effect. For the immersion method, select 4th instar larvae and put them into a small beaker, 20 larvae per cup, and then make up 50mL of wat...

[0079] Example 1: 0.2% pirimiphos-methyl dinotefuran wettable powder WP

[0080]

[0081]

[0082] Technological process: Component I pirimiphos-methyl liquid raw drug is adsorbed with white carbon black to form a mobile powder, then add component II dinotefuran and various auxiliary agents according to the proportion of the formula, fully mix them, and pass through universal crushing After crushing by machine, 0.2% pirimiphos-methyl dinotefuran wettable powder can be obtained. The dinotefuran in the examples can be replaced by chlorothiazoline, piclopyrid, thiamethoxam, clothianidin, and new examples are formed according to the same method and formula ratio.

[0083] Drug efficacy results: the 0.2% pirimiphos-methyl-dinotefuran wettable powder prepared in Example 1 was applied to the control of German cockroaches. Dilute 0.2% pirimiphos-methyl dinotefuran wettable powder on the board surface by 20 times of water dilution, and the control effects on German cockroaches w...

Abstract

The invention provides an insecticide composition containing pirimiphos methyl and a preparation and application thereof. The insecticide composition comprises a component I and a component II, wherein the component I is the pirimiphos methyl, the component II is selected from one of dinotefuran, imidaclothiz, neonicotinoid insecticide, thiamethoxam and clothianidin, and the mass ratio of the component I to the component II is 50:1-1:50. The preparation contains the insecticide composition containing the pirimiphos methyl and an insecticide which is an auxiliary material normally used for pesticide preparations, wherein the mass percent of the insecticide composition is 0.2%-84%. The defect of an insecticide containing a single active component is overcome, the fast-acting and knockout property on sanitary insect pests of the insecticide is improved, the insecticide resistance and tolerance and the like of the sanitary insect pests are reduced, the insecticide composition has excellent preventing effect on blattaria, mosquitoes, flies, termites, flea and the like resistant to the insecticide due to long-term insecticide application, and meanwhile the insecticide application amount, the insecticide cost and environment pollution are reduced.

Description

technical field [0001] The invention relates to a compounded pesticide composition, in particular to the field of sanitation insecticides of compounded insecticidal composition and preparation containing pirimiphos-methyl. Background technique [0002] Sanitation pests refer to all arthropods that can cause direct or indirect harm to human health and affect people's normal life, including two categories: insects and arachnids. Cockroaches (cockroaches), mosquitoes, flies, termites, fleas, and bedbugs all belong to the class Insecta. The main hazards of sanitation pests are blood-sucking harassment and parasitism, and some types of sanitation pests are the vectors of certain infectious diseases in humans, which are very harmful to people's health. Once an outbreak occurs, it is easy to form an epidemic. [0003] Cockroach: Commonly known as cockroach. Belonging to the order Blattata, insects with incomplete metamorphosis, large to medium-sized, broad and flat body. As the ...
