Description

Insecticidal composition containing sulfenamide and tebuconazole amide and application thereof in preventing or controlling animal pests

The application is a divisional application of patent application with application number 201810149394.5 (application date of the original application is 2018, 02, 13 and named as an insecticidal composition).

Technical Field

The invention relates to an insecticidal composition containing sulfenamide and tebuconazole amide. The invention also relates to the use of said insecticidal composition for preventing or controlling animal pests.

Background

Chemical control is an important means of preventing and controlling pests in agriculture. However, at present, effective control may not be possible due to poor efficacy, developed resistance, and the like, caused by the type, living characteristics, living environment, and the like of pests. In particular, for animal pests of the class Insecta, Arachnida and Nematoda, etc., it is becoming increasingly difficult to control using conventional agents. Therefore, it is necessary to find a new means and method for effectively controlling animal pests which are impossible to control or difficult to control.

Thiocarboxamide (Thiitraniloprole) is a thiobenzamide insecticide studied by the university of Qingdao technology, which is disclosed in CN 105153113B. The sulfamide has special effect on beet armyworm and chilo suppressalis, and has the following structural formula:

tetrazoxamide (Tetraniliprole) is a tetrazole-substituted anthranilamide compound developed by Bayer crop science, Inc., which is disclosed in CN 102317279B. The tebuconazole amide has special effect on beet armyworm.

The activity of the individual compounds is good; however, they do not always meet the high requirements which must be met by insecticides, acaricides or nematicides at low application rates or when used against individual pests.

A typical need arising in the field of pest control is to reduce the dosage rate of the control active ingredients and to reduce or avoid adverse environmental or toxicological effects while still allowing effective pest control, and also to have pest control agents which combine knockdown activity and extended control times, i.e. fast-acting and long-acting.

Another difficulty with the use of pesticides is that the repeated and exclusive use of a single pesticidal compound in many cases leads to a rapid selection of pests that either naturally or acclimatize to resistance to the active ingredient. Accordingly, there is a need for pest control agents that help control or overcome resistance to drugs.

There is therefore a continuing need in the field of agricultural pest control to provide pesticidal combinations which often provide improved properties, such as biological properties, synergistic properties.

Disclosure of Invention

The present invention aims to provide a pesticidal composition that solves at least one of the problems described such as improving biological properties, providing synergistic properties, reducing dosage rates, broadening the spectrum of activity, combining knock-down activity with long-lasting action, management of resistance to drugs to delay resistance.

Through a large number of biological test screens, the inventor unexpectedly finds that the combination of the sulfentrazone and the tebuconazole amide can effectively prevent or control pests. Surprisingly, it has been found that the simultaneous (i.e. joint or separate) or continuous application of the active compounds thiamethoxam and tetrazolium amide leads to an enhanced pest control compared to the control rates possible with the individual compounds.

The activity of the combination of the sulfenamide and the tebuconazole amide for controlling pests is greatly higher than the sum of the performances of the individual active compounds. This unexpected effect is a true synergistic effect, not just a summation of activities.

Most of the damage caused by pests to crop plants occurs as early as when the seeds are infested, during storage and after the seeds are sown into the soil and during or after germination of the plants. This stage is particularly critical because the roots and shoots of growing plants are particularly sensitive, and even minor damage can lead to death of the entire plant. Therefore, the protection of seeds and germinating plants by using suitable compositions is of particular interest.

The control of pests by treating plant seeds has long been known and is the subject of constant improvement. However, treating seeds also entails a series of problems that cannot always be solved in a satisfactory manner. Therefore, there is a need to develop methods for protecting seeds and germinating plants which avoid the additional application of crop protection products after planting or after emergence of the plants. In addition, there is a need to optimize the amount of active compound used so that optimum protection is provided to the seed and the germinating plant against attack by pests without the active compound used damaging the plant itself. In particular, the method of treating seeds may also take into account the inherent insecticidal properties of the transgenic plants to achieve optimal protection of the seeds and the germinating plants with minimal crop protection products.

Biological test example:

the combination of different active ingredients to produce crop protection products is an effective and fast way to develop and develop new crop protection products and control resistant pests in agriculture at present. Pesticides of different species, when mixed, typically exhibit three types of action: additive action, synergistic action and antagonistic action. However, the specific action cannot be predicted, and can only be known through a large number of experiments. The compound formula with good synergy obviously improves the actual control effect and reduces the using amount of pesticide, thereby greatly delaying the generation speed of the drug resistance of pests and being an important means for comprehensively controlling the pests.

The co-toxicity coefficient (CTC) of the two medicaments compounded according to a certain proportion is determined, wherein the CTC <80 is antagonistic action, the CTC <80 > and < 120 is additive action, and the CTC > 120 is synergistic action.

The calculation formula is as follows:

death rate (%) - (number of living insects before drug-number of living insects after drug)/number of living insects before drug x 100

Corrected mortality (%) - (treatment-control mortality)/(100-control mortality) × 100

Converting the corrected mortality rate of the tested insects into a probability value (y), converting the treatment concentration (mg/L) into a logarithm value (x), and calculating the lethal middle concentration LC by using a least square method₅₀Then, the cotoxicity coefficient (CTC) was calculated by the Sun Yunpei method. The calculation formula is as follows (taking the thiamethoxam amide as a standard medicament and the virulence index thereof is 100):

measured toxicity index (ATI) ═ standard medicament LC₅₀Test agent LC₅₀)×100

Theoretical virulence index (TTI) ═ A agent ATI × percentage of A in the mixture + B agent ATI × percentage of B in the mixture

Cotoxicity coefficient (CTC) ═ (ATI/TTI) x 100

CTC <80 shows antagonism, CTC <80 > 120 shows additivity, CTC > 120 shows synergy test 1: indoor toxicity determination for cabbage diamondback moth

Soaking leaves which are not contacted with any medicament and have consistent size in prepared liquid medicine for 5s, taking out, naturally drying, placing in an insect breeding box, inoculating tested larvae, breeding at 25 ℃, repeating the treatment for 3 times, wherein the number of the tested insects used in each repetition is 20, simultaneously setting a blank control, checking the number of dead insects in 72h, calculating the death rate and correcting the death rate, solving a toxicity regression equation, and calculating LC₅₀The value is obtained. If the control mortality is greater than 10%, the test is considered invalid.

Table 2 virulence assay results for beet armyworm for the compositions of the invention.

TABLE 2

As can be seen from Table 2, the weight ratio of the thiamethoxam amide to the tetramizole amide is within the range of 10:1-1:25, and the co-toxicity coefficient to the beet armyworm is greater than 120, which indicates that the mixing of the thiamethoxam amide and the tetramizole amide within the range shows a remarkable gain effect.
