Description

Insecticidal composition for preventing and controlling peach fruit borer
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to an insecticidal composition for preventing and controlling peach fruit borer.
Background
Chlorantraniliprole acts on the ryanodine receptor of insects to cause excessive release of calcium ions stored in smooth muscle and striated muscle cells, thereby causing weak muscle regulation function of the insects, affecting the behaviors of the insects, stopping feeding rapidly and finally killing the insects. The drug has stronger permeability and systemic conductivity, and the drug entering the plant is conducted to other parts without drug application along xylem, thereby being beneficial to protecting the new tissue; stomach toxicity is the main ingredient, and the contact killing effect is secondary; long lasting period and rain wash resistance. The product is mainly used for preventing and controlling rice pests at present, and has more special effects on pests with resistance to other rice pesticides, such as cnaphalocrocis medinalis, chilo suppressalis, tryporyza incertulas and borer, and has good prevention and control on gall midge, rice weevil and rice weevil.
Chlorbenzuron, the English name of chlorbenzuron, belongs to a benzoyl urea insect chitin synthesis inhibitor, and is an insect hormone pesticide. By inhibiting the activities of insect cuticle chitin synthase and uridine coenzyme, insect chitin synthesis is inhibited, resulting in death of insects without normal molting. Affecting the respiratory metabolism of eggs and the DNA and protein metabolism in the embryo development process, so that the larvae in the eggs lack chitin and cannot hatch or die immediately after hatching; the application in larval stage can prevent the formation of new epidermis of pest, delay development, or lack hardness, and can not normally molt to cause death or formation of malformed pupa death. Exhibits excellent insecticidal activity against metamorphosis insects, particularly lepidopteran larvae.
Peach fruit borer (Carposina niponensis Walsingham) commonly known as peach fruit moth, peach fruit jelly, and belongs to the family Lepidoptera fruit moth. The peach fruit borer is one of the common pests on peach trees, and the mature larvae overwintere in winter cocoons in soil. Most of the soil is distributed in the surface soil with the depth of 5-10 cm within the range of 1 meter around the trunk. The small insects are particularly annoying, especially in the mature period of the peach, almost have the same smell and identification capacity, the peach is specially picked to eat sweet and juicy, a hole is drilled on the fruit, the fruit pulp is eaten after being hidden inside, the generation of the peach small insects is replaced, so to speak, the peach is not killed, the peach is endangered for two generations in one year, and the young fruit period of 5 and 6 months is endangered once, so that the yield of the peach is reduced; 7. the peach is endangered once again in 8 months, so that the quality of the peach is greatly reduced.

3.3 pharmaceutical treatment
Apples with basically consistent undeployed size and maturity (fruit chest diameter 7-8cm, weight 200 g) are selected, cleaned and dried, immersed in the fruit in real time, and the control is firstly treated and then sequentially carried out from low concentration to high concentration. Soaking in the measured liquid medicine for 10s, taking out, and naturally airing. Then putting apples into a beaker, inoculating 15 apples into 15 peach-shaped heartworm larvae with the age of 3, sealing each apple by using gauze, and placing the apples in an artificial constant-temperature insect-raising room with the temperature of 25+/-1 ℃ and the relative humidity of 60-70% and the photoperiod of 14:10 (L: D).
4 data investigation and statistical analysis
4.1 investigation time and method
After 48 hours of chlorantraniliprole treatment, the number of dead and alive insects in each treatment is checked; after chlorbenzuron treatment for 96 hours, checking the death and alive number of each treatment; after 96h of the mixture, the number of dead and alive insects (fruits cut with drill) was checked for each treatment. Larval death criteria: the tip of the nipper with the tip is used for lightly touching the insect body of the test insects, and the death is the death of the people who have obvious poisoning symptoms and can not normally crawl.
4.2 method for evaluating synergy
The mortality rate of the blank control is less than 5% without correction; the death rate of the blank control is 5% -10%, and the corrected death rate of each treatment is calculated by using an Abott formula; the mortality rate of the blank control is more than 10%, and the test needs to be reworked. Calculating test results by adopting DPS data processing software, and respectively solving virulence regression equations and LC of two single doses and five proportions of test agents 50 、LC 90 And 95% confidence limits, and record raw data for each treatment all replicates. According to Sun&Johnson (1960) co-toxicity coefficient method (CTC) found the co-toxicity coefficient (CTC) of each compounding combination. Namely CTC is less than or equal to 80 and is antagonistic, 80<CTC<120 is additive, and CTC is greater than or equal to 120 is synergistic. The calculation formula of the co-toxicity coefficient is as follows
Drug combination Theory Toxicity Index (TTI) =toxicity index of agent a×percent (%) of agent a in the combination+toxicity index of agent b×percent (%)

6 experimental results
TABLE 5 example 3 results of field efficacy test for controlling peach fruit borer
As can be seen from table 5, the specific analysis is: the average control effect of 300 g/L chlorantraniliprole/chlorbenzuron suspending agent of test object example 3 in treatment 1 (3000 times of the dosage of the preparation), treatment 2 (2500 times of the dosage of the preparation) and treatment 3 times of 2000 times of the dosage of the preparation is as follows: 93.07%, 95.05% and 97.03%, the average control effect of 35% chlorantraniliprole water dispersible granule treatment 4 (7000 times the dosage of the preparation) of the control is 95.05%, the average control effect of 25% chlorbenzuron suspending agent treatment 5 (1500 times the dosage of the preparation) of the control is 82.18%, wherein the average control effect of treatment 3 is the highest. The differences between the treatment 1, the treatment 3 and the treatment 5 are remarkable, the average differences between the treatment 5 and the rest 4 treatments are remarkable, and the rest treatments have no remarkable differences (0.05 level).
10 days after application, the average control effects of 300 g/L chlorantraniliprole/chlorbenzuron suspending agent of test object example 3 in treatment 1, treatment 2 and treatment 3 are as follows: 90.32%, 93.55% and 95.48%, the average control effect of 35% chlorantraniliprole water dispersible granule treatment 4 of the control is 92.26%, the average control effect of 25% chlorbenzuron suspending agent treatment 5 of the control is 89.39%, wherein the average control effect of treatment 3 is the highest. No significant differences were found between treatment 2, treatment 3, and treatment 4, no significant differences were found between treatment 1 and treatment 5, and significant differences were found between the remaining treatments (0.05 level).
15 days after the application, the average control effects of 300 g/L chlorantraniliprole and chlorbenzuron suspending agent treatment 1, treatment 2 and treatment 3 of the tested object are as follows: 88.24%, 90.34% and 92.02%, the average control of 35% chlorantraniliprole water dispersible granule treatment 4 of control was 88.24%, and the average control of 25% chlorantraniliprole suspension treatment 5 of control was 84.03%, wherein the average control with treatment 3 was highest. There was no significant difference between treatment 1 and treatment 4, and the difference between treatments was significant (0.05 level).
In a word, the chlorantraniliprole chlorbenzuron suspending agent has a good control effect, and 300 g/L of the test agent has a good control effect on peach fruit borers, and is safe to peach trees within the range of the agent supply amount.
