Description

A kind of insecticidal composition containing bromotraniliprole

technical field

The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing bromotraniliprole.

Background technique

Imicyafos (AKD-3088) is a cyanamide heterocyclic organic compound, which is composed of asymmetric organophosphorus and cyanoimidazolidine of nicotinic insecticides, and can be used for radish, carrot, strawberry, eggplant, tomato , cucumber, melon, watermelon, sweet potato and potato and other crops, its chemical structure is:

Bromotiliprole mainly activates ryanodine receptors, releases calcium ions stored in smooth muscle and striated muscle cells, causes muscle regulation weakness, paralysis, and finally the death of pests. The active ingredient shows a very significant selectivity difference between mammals and pest ryanodine receptors, greatly improving the safety to mammals and other vertebrates. O-formamidobenzamide insecticides have a good control effect on Lepidoptera Noctuidae, Mothidae, Fruit Mothidae, Leaf Rolleridae, Melydidae, Plutella Plutella, and Thymothidae , It can also control various non-lepidopteran pests such as Coleoptera Weevilidae, Chrysophyte, Diptera Liminidae, and Bemisia tabaci. It has a very outstanding control effect on larvae. The disadvantage is that it has limited control effect on adults, no ovicidal effect, and weak systemic conduction.

After long-term use of bromotraniliprole, the resistance of pests to it has increased year by year, which has led to an increase in the amount of pesticides used, resulting in adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy. Moreover, the use of single-component insecticides is likely to lead to resistance of pests, which is an urgent problem to be solved in the process of using pesticides. However, the creation of new high-efficiency insecticide compounds requires a large investment, a long cycle, and high scientific research capabilities. In line with the current status of my country's pesticide enterprises. The compounding of pesticides can not only solve the problem of high toxicity and poor effect of a single pesticide, but also requires less investment and a short research and development cycle, which is suitable for the current situation of domestic pesticide companies, and the interactive use of different pesticides can delay the drug resistance of agents Therefore, the combination of pesticides with different mechanisms of action is a research hotspot in the field of pesticides.

Indoor bioassay screening and field test:

The present invention adopts the method of combining indoor bioassay and field test. Unless otherwise specified, the ratios (including percentages) mentioned below are all mass ratios.

Examples of activity assays:

(1) Drugs to be tested

95% imicyafos original drug, 93% bromotraniliprole original drug.

(2) Source of tested insects

Plutella xylostella larvae raised for generations indoors, indoor conditions: temperature (26±2)°C, relative humidity 68%±5%, photoperiod 16/8h (L/D).

(3) Single-dose determination method

The two groups of original drugs were dissolved in a small amount of acetone by worm soaking method, and then diluted with 0.1% Tween aqueous solution to form 5 concentrated solutions with equal difference, which were diluted in beakers for later use, and clear water was used as a control.

Plutella xylostella larvae of the same size were immersed in the medicinal solution of the insect cage for 5 seconds, and after absorbing the excess medicinal solution, they were placed in a petri dish with a diameter of 9 cm, and the dish was covered with fresh vegetable leaves. 10 heads were treated at each concentration, repeated 4 times, and a blank control was set. After keeping in the light incubator at (27±1)°C for 24 hours, the mortality was checked, and those who did not respond to the worm body with a needle were considered dead. Mortality was corrected by Abbott's formula, and then according to concentration logarithm-mortality probability value analysis (Bliss) method, the regression equation of toxicity and the value of LC ₅₀ were calculated.

(4) Combined toxicity assay method with different ratios

According to the toxicity test results of a single agent, the ratios of imicyafos to bromotraniliprole were 5:13, 7:11, 9:9, 11:7, and 13:5 according to 18% by weight of active ingredients.

The above-mentioned 1.3 method was used to measure the toxicity, and the _LC50 was calculated, and the co-toxicity coefficient (CTC) was calculated according to Sun Yunpei's method.

Bromotraniliprole Toxicity Index (TI) = LC ₅₀ of imicyafos / LC ₅₀ of Bromotraniliprole × 100

Actual Toxicity Index (ATI) of M = LC ₅₀ of imicyafos / LC ₅₀ of M × 100

M's Theoretical Toxicity Index (TTI) = TI of imicyafos × P imicyafos + TI of bromotraniliprole × P bromotraniliprole

M's co-toxicity coefficient (CTC)=M's ATI/M's TTI×100

In the formula:

M is a mixture of different ratios of bromantraniliprole and imicyafos

P bromotraniliprole is the proportion of bromotraniliprole in the mixture

P imicyafos is the proportion of imicyafos in the mixture

(5) Toxicity test results and analysis

Table 1 imicyafos, bromotraniliprole to Plutella xylostella indoor assay results

As can be seen from the table, in the mixing of different proportions, its co-toxicity coefficient is greater than 120, showing a certain synergistic effect, wherein imicyafos: bromotraniliprole is the most obvious synergistic effect of 11:7, The co-toxicity coefficient was 192.80. The test results show that under indoor conditions, bromotraniliprole and imicyafos have higher activity against diamondback moth. The test results of different ratios show that according to the active ingredient imicyafos: bromotraniliprole is 5: 13, 7:11, 9:9, 11:7, 13:5, all showed a strong synergistic effect, and the synergistic effect was the best when the ratio of imicyafos:bromotraniliprole was 11:7.
