Description
The application is a divisional application with the application number of 201810149840.2 (the application date of the original application is 2018, 02 and 13 days, and the invention name is an insecticidal composition).
Technical Field
The invention relates to an insecticidal composition, which contains active compounds of sulfenamide and cyantraniliprole. The invention also relates to the use of said pesticidal 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.
Thioamide (Thiotriiliprole) is a thiobenzamide pesticide studied by the Qingdao university of science and technology, which is disclosed in CN 105153113B. The sulfamide has special effects on asparagus caterpillar and chilo suppressalis, and has the following structural formula:
cyantraniliprole, also called cyantraniliprole (cyantraniliprole), is a second generation of ryanodine receptor inhibitor insecticides successfully developed by DuPont company after chlorantraniliprole, is formed by changing various polar groups on a benzene ring, has higher efficiency, is more widely applicable to crops, and can effectively control lepidoptera, hemiptera and coleopteran pests.
The activity of the single compound 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. Therefore, 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.

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 pesticidal properties of the transgenic plants to achieve optimal protection of seeds and germinating plants using 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 inventor conducts a large number of tests and effectiveness analysis on different mixture ratios of the thiamethoxam amide and the cyantraniliprole through a large number of screening tests, finds that the obtained insecticidal composition has a gain effect within a certain mixture ratio range, is not only a simple addition of two medicaments, and is specifically described in the following embodiment.
And (3) according to the combined action measurement of part 7 of the pesticide mixing according to the agricultural industry standard (NY/T154.7-2009) of the people's republic of China in the pesticide indoor bioassay test rule, calculating the corrected mortality of each treatment according to survey data, and calculating the cotoxicity coefficient (CTC value) of the mixed pesticide according to the Sun cloud Peel method.
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:
mortality (%) = (number of live insects before drug-number of live insects after drug)/number of live insects before drug × 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 method 50 Then, the cotoxicity coefficient (CTC) was calculated by the Sun Yunpei method. The calculation formula is as follows (with sulfamide as a standard medicament, the toxicity index is 100):
measured virulence index (ATI) = (Standard medicament LC) 50 Test agent LC 50 )×100
Theoretical virulence index (TTI) = a medicament ATI x percentage of a in the mixture + B medicament ATI x percentage of B in the mixture
Co-toxicity coefficient (CTC) = (ATI/TTI mixed dose) × 100
CTC <80 shows antagonism, CTC <80 > 120 shows additivity, CTC > 120 shows synergy test 1: indoor toxicity determination for rice stem borer
