Effect test

Embodiment 1

[0035] The inventors tested the indoor activity of the insecticide composition of the diphenoxyfen derivative.

[0036] Experimental effect calculation method:

[0037]

[0038]

[0039] The control effect was converted into a probability value (y), the concentration of the drug solution (μg / ml) was converted into a logarithmic value (x), and the toxicity equation and the inhibitory intermediate concentration EC50 (half maximum effect concentration) were calculated by the least square method.

[0040] Calculate the toxicity index and co-toxicity coefficient (CTC) of the drug by calculating the co-toxicity coefficient of the compound according to the toxicity index.

[0041]

[0042]

[0043]

[0044] Experimental judgment basis:

[0045] When CTC≤80, the composition exhibits antagonistic effect; when 80

[0046] Mix 4-p-phenoxyphenoxymethyl-2-n-propyl-...

Embodiment 2

[0050] The inventors tested the indoor activity of the insecticide composition of the diphenoxyfen derivative.

[0051] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0052] Mix 4-p-phenoxyphenoxymethyl-2-isopropyl-1,3-dioxolane and ethiprole at a weight ratio of 60:1 to 1:60 to obtain a variety of compositions, select one of Compositions corresponding to several specific weight ratios measure its toxicity to Spodoptera litura, and the test results are shown in Table 2:

[0054]

Embodiment 3

[0056] The inventors tested the indoor activity of the insecticide composition of the diphenoxyfen derivative.

[0057] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0058] Mix 4-p-phenoxyphenoxymethyl-2-n-butyl-1,3-dioxolane and ethiprole at a weight ratio of 80:1 to 1:80 to obtain a variety of compositions, among which Compositions corresponding to several specific weight ratios measure its toxic effect on thrips, and the test results are shown in Table 3:

[0059] Table 3 compares the toxicity test results to thrips

Abstract

The invention provides a difenolan derivative insecticide composition and application thereof to prevention and control of pests. The effective component of the difenolan derivative insecticide composition is formed by compounding a 1,3-dioxolane compound containing a 4-p-phenoxy phenoxy methyl structure and any one of ethiprole, pyridalyl, dinotefuran, flupyradifurone, thiacloprid, clothianidin,piperidine, imidaclothiz, sulfoxaflor and flonicamid; furthermore, through experimental detection, the medicine effect of the insecticide composition is obviously higher than the preventing effect ofsingle insecticide product / component, so that the use dose (the total insecticide application quantity) of the composition is reduced, the disease-resistant risk of the pests is effectively reduced, the use efficiency of the composition is improved, and environmental pollution is obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of insecticide compositions, and in particular relates to an insecticide composition of a diphenoxyfen derivative and its application in pest control. Background technique [0002] On March 17, 2015, the Ministry of Agriculture stated that my country's agricultural production started to implement the "double action" of zero growth in chemical fertilizer use by 2020 and zero growth in pesticide use by 2020. For many years, the use of chemical fertilizers and pesticides in my country has shown a double growth trend; from 2012 to 2014, the average annual use of pesticides for crop disease and insect pest control was 311,000 tons, an increase of 9.2% over 2009 to 2011. The "Double Action" aims to promote the reduction of chemical fertilizers to improve efficiency, the reduction of pesticides to control damage, and actively explore the path of modern agricultural development with high output, product safety, reso...
