Description

Insecticidal composition containing thiobenzamide insecticide

The application is a divisional application of patent application No. 201810149944.3 (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 containing a thiobenzamide insecticide, which contains active compounds of sulfenamide and ivermectin. 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 Insecta, arachnida and Nematoda classes, the control of pests using conventional agents is becoming increasingly difficult. 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 pesticide studied by the Qingdao university of science and technology, which is disclosed in CN 105153113B. The sulfamide has special effect on beet armyworm and chilo suppressalis, and has the following structural formula:

the ivermectin is a novel broad-spectrum, high-efficiency and low-toxicity antibiotic anti-parasitic drug, and has good expelling and killing effects on parasites in vivo and in vitro, particularly nematodes and arthropods.

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 arises in the field of pest control to reduce the dosage rate of control active ingredients and to reduce or avoid adverse environmental or toxicological effects while still allowing effective pest control, and also to have a combination of knock-down activity and extended control times, i.e. fast-acting and long-acting pest control agents.

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 pesticidal compositions that solve at least one of the problems described such as improving biological properties, providing synergistic properties, reducing dose 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 inventors unexpectedly found that combining sulfenamide and ivermectin can effectively prevent or control pests. Surprisingly, it has been found that the simultaneous (i.e. combined or separate) application of the active compounds thiamethoxam and ivermectin or the successive application of the active compounds thiamethoxam and ivermectin gives an enhanced pest control effect compared to the control rates possible with the individual compounds.

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.

Preferably, the seeds are in a sufficiently durable state so as not to be damaged during handling. Generally, the seeds may be seeds harvested from the field, removed from the plant, isolated from any cob, stem, husk and surrounding pulp or other non-seed plant material. The seed may also preferably be biologically stable to the extent that the treatment does not cause biological damage to the seed. The treatment applied to the seed may be between seed harvest and seed sowing or at any time during the sowing process. The seeds may also be pregerminated before or after treatment.

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, synergistic and antagonistic. 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 ratios of the thiamethoxam amide and the ivermectin through a large number of screening tests, and finds that the obtained insecticidal composition has a gain effect within a certain ratio range, and is not only a simple addition of the two agents, but also 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 CTC <80 is antagonistic action, CTC <80 and not more than 120 is additive action, and 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 logarithmic value (x), and calculating the inhibitory concentration LC by the least square method ₅₀ Then, 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, the toxicity index is 100):

actually measured virulence index (ATI) = (standard pharmaceutical 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 result of citrus red spiders
