Description

[0001] This application is a divisional application of the Chinese invention patent application. The original application date is November 29, 2022, application number 202211511683.8, the name of the invention: A synergistic binary composition containing two active components and its application, publication number: CN118104660A. Technical Field

[0002] The invention belongs to the field of pesticides and relates to a synergistic binary composition containing two active components and application thereof. Background Art

[0003] In the actual process of agricultural production, the application of chemical agents is one of the most effective means of preventing and controlling plant diseases and insect pests. However, the most common problem caused by chemical pest control is the development of resistance of pests and mites. At the same time, the long-term continuous high-dose application of a single chemical insecticide and acaricide is likely to cause a series of problems such as agent residues and environmental pollution. Reasonable compounding or mixing of chemical insecticides and acaricides has the positive characteristics of expanding the insecticide and acaricide spectrum, improving the control effect, extending the appropriate period of application, reducing the amount of medicine used, reducing drug damage, reducing residues, and delaying the occurrence and development of pest and acaricide resistance. Compounding or mixing of insecticides and acaricides is one of the most effective ways to solve the above problems. The price of developing new pesticides continues to rise. In contrast, the development and research of high-efficiency, low-toxicity, and low-residue compounds and mixtures have low investment and short development cycle, and have attracted attention at home and abroad, and have increased their development efforts.

[0004] Chinese invention patent CN112457288 discloses a piperic acid derivative and its application, wherein compound I-72 has contact and stomach poison activity and good conduction activity, and can be used to control a variety of Lepidoptera, Hemiptera, Thysanoptera, Coleoptera and other pests.

The two active components A and B are compounded within an appropriate ratio range to improve the control effect on pests and mites such as wheat aphids and diamondback moths. DETAILED DESCRIPTION

[0030] The following examples are used to explain the present invention in detail, so as to facilitate further understanding of the present invention. The active component A is selected from compound I-72 (prepared according to the description in the patent document CN112457288, with a content of 97%); the active component B and other raw materials are all commercially available products, and each component is measured by weight percentage.

[0031] Example 1: Indoor synergistic screening test of compound 1-72 mixed with different plant growth regulators against wheat aphids Test target: wheat aphid Sitobion miscanthi (Fabricius).

[0032] Preparation of drug solution: According to different test needs, use an electronic analytical balance to accurately weigh the test samples, dissolve the original drug in acetone, and then use 0.1% Tween 80 water to dilute it into a series of drug solutions with a certain concentration gradient according to the designed experimental dosage.

[0033] Experimental method: Firstly, select wheat seedlings with neat and uniform aphids, with an insect load of about 30-40 heads per pot of wheat. Then, spray evenly from low dose to high dose according to the experimental design, 2.5 mL per pot, and repeat each treatment 3 times. Set up a blank control CK.

[0034] The treated test materials were placed in an observation room where the temperature, humidity and light intensity could be adjusted as needed. The number of dead and live insects was investigated after 48 hours and the corrected mortality rate was calculated using the Abbott formula.

[0035] The Bliss method was used to evaluate the synergistic effect of mixed pesticides. Based on the concept of independent combined effects proposed by Bliss, he believed that the theoretical mortality rate P of mixed pesticides can be calculated by the following formula:

[0036] P=Pm+Pn(1-Pm)

[0037] Pm is the measured mortality rate (%) of the target when the concentration of the first active component is m; Pn is the measured mortality rate (%) of the target when the concentration of the second active component is n.

[0038] If the actual mortality rate of the target after the two active components are mixed at a certain concentration is greater than the theoretical mortality rate P, it is determined that the two active components have a synergistic effect when mixed at the set concentration, otherwise it is an antagonistic effect. The test results are shown in Table 1.

[0040]

[0041]

[0042] Example 2: Indoor synergistic screening test of compound I-72 mixed with different insect attractants and insecticides against Plutella xylostella

[0043] Test target: 2nd instar larvae of diamondback moth (Plutella xylostella).

[0044] Preparation of drug solution: According to different test needs, use an electronic analytical balance to accurately weigh the test samples, dissolve the original drug in acetone, and then use 0.1% Tween 80 water to dilute it into a series of drug solutions with a certain concentration gradient according to the designed experimental dosage.

[0045] Experimental method: First, select cabbage leaves, and immerse them in the prepared solution for 10 seconds in the order from low dose to high dose according to the experimental design. After natural drying, place them in a culture dish with a diameter of 9 cm and filter paper, and inoculate neatly arranged healthy test insects. Each treatment has 10 heads and each treatment is repeated 3 times. A blank control CK is also set up.

[0046] The treated test materials were placed in an observation room where the temperature, humidity and light intensity could be adjusted as needed. The number of dead and live insects was investigated after 72 hours and the corrected mortality rate was calculated using the Abbott formula.

[0047] The synergistic effect of the mixture was evaluated by the Bliss method, which was the same as in Example 1. The test results are shown in Table 2.
