Description

[0001] This application is a divisional application with application number 202210247896.8, application date March 14, 2022, and invention name “A composition containing pyrethroid insecticides and its application”. Technical Field

[0002] The present invention belongs to the technical field of pesticide compounding, and specifically relates to a composition containing a biologically effective amount of Compound I and at least one pyrethroid insecticide, and methods for using the composition to control insect pests in agricultural and non-agricultural environments. Background Art

[0003] In recent years, the incidence of various crop pests has been increasing year by year, with the affected areas expanding year by year. This has caused significant damage to crops, leading to reduced crop yields and increased agricultural production costs. To improve pest control effectiveness, farmers have increased pesticide dosages or arbitrarily mixed pesticides. This unscientific use of pesticides not only fails to achieve synergistic effects, but also leads to pesticide waste, excessive residues, environmental pollution, and the development of pesticide resistance in pests. Therefore, there is an urgent need to develop a composition for pest control that can expand the scope of pest control, reduce pesticide dosage, and delay the development of pesticide resistance.

[0004] In the real world of agricultural production, the long-term, continuous use of a single pesticide quickly leads to pest resistance, resulting in reduced control effectiveness, increased pesticide usage, and exacerbated pesticide residues in agricultural products and ecological damage. Combining pesticides with completely different mechanisms of action is an effective way to delay the development of pest resistance, expand the insecticide spectrum, extend the lifespan, and reduce pesticide usage. However, a major challenge is how to formulate a combination that creates synergy rather than antagonism between the various pesticides.

[0005] Patent document CN 111909143 A discloses Compound I, which has broad-spectrum insecticidal activity, particularly effective against Lepidoptera, Hemiptera, Coleoptera, Thysanoptera, Diptera, and mites. However, it does not disclose how to combine Compound I with other drugs to achieve enhanced efficacy.

[0006] The structural formula of compound I is shown below:

[0007]

[0008] Pyrethroids are a class of synthetic insecticides that mimic the chemical structure of natural pyrethrins. They are sodium channel modulators, and their insecticidal effects are mainly contact and stomach poisoning. Pyrethroids have the following advantages: (1) High efficiency: The insecticidal activity is 2 to 10 times that of general organophosphorus insecticides; (2) Broad spectrum: They have good control effects on various fruit tree pests, such as apple and pear borers, cutworms, stink bugs, flat boat moths, geometrids, and pests with chewing and piercing mouthparts; (3) Low toxicity: The toxicity to humans and animals is lower than that of organophosphorus and carbamate pesticides, and the dosage is small and safe to use; (4) Low residue: They have less pollution to crops and the environment, are easily decomposed in the natural environment, and have low residue. Currently, there are nearly 80 pyrethroid insecticides developed worldwide, of which 24 are used for agricultural pest control.

[0009] However, the above two compounds still have the problem of drug resistance and insecticidal activity needs to be improved. Summary of the Invention

[0088] 2. Indoor Toxicity Determination Example

[0089] (1) Test pests: cotton aphid (Aphis gossypii Glover), tomato whitefly (Bemisia tabaci), cabbage diamondback moth (Plutella xylostella), corn armyworm (Mythimna separata Walker).

[0090] (2) Determination method:

[0091] Pest toxicity determination method

[0092] Pest toxicity assay Cotton aphids were used as test materials, and the toxicity of compound I, pyrethroid insecticides and their mixed preparations were determined by the insect immersion method.

[0093] With reference to the Pesticide Part 6: Insecticide Activity Test - Immersion Method in the Agricultural Industry Standard of the People's Republic of China NY / T 1154.6-2006 "Guidelines for Indoor Bioassays of Pesticides", the test agents (including Compound I and pyrethroid insecticides) were first prepared into 5 concentration gradients (based on the LC values ​​of the compounds on different pests) using a suitable solvent (the type of solvent is such as acetone, methanol, N,N-dimethylformamide and dimethyl sulfoxide, etc., and is selected based on its solubility for the sample). 50 value, setting the concentration gradient according to geometric ratio or arithmetic difference), the compound I and the pyrethroid insecticides for mixing were respectively adjusted according to their LC 50 The values ​​were set to a series of ratios according to mass ratio, and the final mass concentration (the total mass of compound I and pyrethroid insecticide) was prepared according to different ratios.

[0094] After the target insects have been immersed in the solution for 5-10 seconds, remove excess solution with filter paper and transfer the insects to normal conditions for rearing. Each treatment consists of four replicates, with 10-20 insects immersed in each replicate. A control treatment containing the corresponding organic solvent without the pesticide is also included.

[0095] Pest toxicity assay The toxicity of compound I, pyrethroid insecticides and their mixed preparations were determined using cabbage diamondback moth, corn armyworm, tomato whitefly and other pests as test materials using the leaf dip method.

[0096] Referring to the Pesticide Indoor Bioassay Test Guidelines of the Agricultural Industry Standard of the People's Republic of China NY / T 1154.14-2008, Part 14: Leaf Dipping Method, the test agents (including Compound I and pyrethroid insecticides) were first prepared into 5 concentration gradients (based on the LC / MS / MS of the compounds for different pests) with a suitable solvent (the type of solvent is acetone, methanol, N, N-dimethylformamide and dimethyl sulfoxide, etc., and is selected based on its solubility for the sample). 50 value, setting the concentration gradient according to geometric ratio or arithmetic difference), the compound I and the pyrethroid insecticides for mixing were respectively adjusted according to their LC 50 The values ​​are set in a series of proportions according to mass ratio, and the final mass concentration (referring to the total mass of compound I and pyrethroid insecticide) is prepared according to different ratios.

[0097] Immerse leaf discs or segments in the test agent solution for 10 seconds (the immersion time can be extended or shortened depending on the agent's characteristics). Remove and air dry, then place in a Petri dish containing 1% water agar or moisturizing filter paper. Inoculate the dish with at least 10 test insects per replicate. Each treatment should be replicated at least four times, and a treatment without the agent (including all organic solvents and emulsifiers) should serve as a blank control.

[0098] According to Sun Yunpei's method, the co-toxicity coefficient (CTC value) of two drugs in different ratios is calculated. A CTC of ≥120 indicates a synergistic effect, a CTC ≤80 indicates an antagonistic effect, and a CTC of 80 < CTC <120 indicates an additive effect. The CTC of the mixture is calculated according to formula (1), formula (2), and formula (3):

[0099]

[0100] Where:

[0101] ATI - measured toxicity index of mixture;

[0102] S——LC of standard pesticide 50 , the unit is milligrams per liter (mg / L);

[0103] M——LC of the mixture 50 , in milligrams per liter (mg / L)

[0104] TTI=TI A ×P A +TI B ×P B (2)

[0105] Where:

[0106] TTI – Theoretical Toxicity Index of Mixtures;

[0107] TI A ——Agent toxicity index;

[0108] P A ——The percentage of agent A in the mixture, in percentage (%);

[0109] TI B ——Toxicity index of agent B;

[0110] P B ——The percentage of agent B in the mixture, in percentage (%).

[0111]

[0112] Where:

[0113] CTC – Co-toxicity coefficient;

[0114] ATI – Actual Toxicity Index of Mixture;

[0115] TTI - Theoretical Toxicity Index of Mixture.

[0116] Mixtures of different pesticides typically exhibit three types of effects: additive, synergistic, and antagonistic. However, the specific effects are unpredictable. The compositions described herein contain Compound I and a pyrethroid insecticide as the active ingredients, and are illustrated using bioassay examples.

[0117] Indoor test on the activity of pesticides against Plutella brassicae

[0118] In this test, the indoor activity test of the compounds against Plutella brassicae was carried out using the leaf dipping method to determine the activity of the insecticidal compositions of Examples 1 to 4 against Plutella brassicae.

[0119] Example 1: To verify the effects of different ratios of Compound I and cypermethrin on Plutella brassicae, indoor toxicity tests on Plutella brassicae were conducted using different ratios of Compound I and cypermethrin. The concentrations were prepared according to the mass ratios in the table, and indoor insecticidal tests were conducted. The test results are as follows:
