Description

Technical Field

[0001] The invention belongs to the technical field of pesticides, and particularly relates to application of an insecticidal composition containing high-efficiency cyhalothrin to dipteran pests. Background Art

[0002] Pyrethroids (PY) pesticides have gradually replaced organochlorine and other highly toxic and long-residue insecticides due to their high efficiency, wide range of action, strong stability and relatively low toxicity, and are widely used in agriculture, forestry and residential pest control. Pyrethroids have the fastest growth among the four major types of insecticides. While pyrethroids are widely used, they also have problems such as easy resistance, high fish toxicity and low systemicity.

[0003] High-efficiency cyhalothrin is a sodium channel regulator that acts on the insect nervous system. It can keep sodium channels unobstructed, causing insects to become overexcited. In some cases, it can also cause nerve conduction blockade (sodium channels participate in the conduction of action potentials along nerve axons).

[0004] Flupyroxystrobin is a methoxyacrylate insecticide with a CAS number of 114077-75-7 and a chemical structure of:

[0005]

[0100] Twenty newly emerged male and female adults (female:male=1:1) were inoculated into each test tube and sealed with white gauze. Acetone treatment was used as a control, and each treatment was repeated 4 times.

[0101] Data investigation: Check the number of deaths after 4 hours, calculate the toxicity regression equation and LC 50 .

[0102] Data statistics and analysis: If the blank control mortality rate is less than 5%, no correction is required; if the blank control mortality rate is 5% to 10%, correction mortality rate is required; if the blank control mortality rate is more than 10%, the test needs to be repeated.

[0103] The calculation formula is as follows:

[0104]

[0105]

[0106] Theoretical toxicity index of mixture TTI = TI A ×P A +TI B ×P B

[0107] Co-toxicity coefficient

[0108] Where: P A , P B are the proportions of active ingredients A and B in the composition, respectively.

[0109] Co-toxicity coefficient (CTC):

[0110] CTC < 80 indicates antagonistic effect, CTC > 120 indicates synergistic effect, and 80 < CTC < 120 indicates additive effect.

[0111] IBM SPSS Statistics 20 statistical analysis system was used to calculate the LC of the toxicity regression line. 50 Values ​​and their 95% confidence limits and correlation coefficients R 2 , evaluate the activity of the test agent on biological test materials.

[0112] The results show:

[0113] The results in Table 1 show that the combination of Flupyroxystrobin and highly effective cyhalothrin in the range of 1:20 to 18:1 showed an additive or synergistic effect in the control of Bradya fungus gnat on chives; among them, Flupyroxystrobin and highly effective cyhalothrin had a synergistic effect in the range of 1:16 to 18:1, and the LC of Flupyroxystrobin and highly effective cyhalothrin against Bradya fungus gnat on chives was 2:3. 50 7.276 mg·L -1 The co-toxicity coefficient was 218.902, showing an obvious synergistic effect.

[0117] Field efficacy examples

[0118] Field test on the efficacy of different pesticides in controlling chive maggots

[0119] Test reference standard: GB / T 17980.67-2004 "Guidelines for field efficacy tests of pesticides (II) Part 67: Insecticides for the control of leek maggots and root maggots"

[0120] Test time and location: May 2021, leek planting base in Jiangshan Town, Laixi City, Shandong Province;

[0121] Test crops: Chinese chives (Allium tuberosum Rottler), variety: Snow Allium 791;

[0122] Target of control: Bradyphis chinensis;

[0123] Plot setting: Each treatment plot has an area of ​​20m 2 , set 4 times of replication, and the cultivation conditions of all experimental plots were uniform;

[0124] Test method: Use ground spraying to control adult insects;

[0125] Application period: Add water to the pesticide (45kg / 667m 2 ) dilute and use a backpack sprayer to spray the pesticide evenly.

[0126] Investigation: Investigate the insect population and damage to leeks 3 and 7 days after application.

[0127] Treatment:

[0135]

[0136] Note: The above data are the average of 4 repetitions, the values ​​are rounded to two decimal places, and letters indicate significant differences (0.05 / DMRT method).

[0137] Field efficacy tests showed that, as described in Table 3, a mixture of Flupyroxystrobin and highly effective chlorfenapyr had a good control effect on Bradysia chinensis.

[0138] The mixture of Flupyroxystrobin and highly effective chlorflucythrinate has good seedling protection and control effects on leeks, and has a long lasting effect.

[0139] The insecticide composition or the preparation obtained by compounding the present invention has significant control effect, and is superior to a single agent in delaying the generation of drug resistance and prolonging drug retention. In addition, no compound agent was found to cause phytotoxicity to crops in the test, indicating that the insecticide composition or preparation obtained can reduce production costs and use costs and is safe for crops when the insecticide synergistic synergy is improved.

[0140] Although the present invention has been described in detail above with general instructions and specific implementation schemes, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
