Description
Technical Field
The application relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing Oxazosulfanyl and antifeedant hydrazine.
Background
It is well known that the application of chemical agents is the most effective means for controlling agricultural pests, but the current irregular use of pesticides causes stronger and stronger resistance of pests to pesticides, and causes the annual increase of pesticide usage, thereby causing more and more serious environmental pollution. There is therefore an urgent need to rationally use pesticides and to prepare formulated pesticides to reduce pest resistance.
Rice pests damage rice in the modes of sucking juice, gnawing leaves and the like, so that plants are short, stems are black and odorous, no ears are drawn or seed blighted, and yield reduction and even harvest failure can be caused when the rice pests are serious. The rice pests have large propagation quantity, lay eggs on rice stems and leaves, and the larvae gnaw the stems, so that empty stems and broken stems can be caused. In addition, rice pests can also transmit rice virus diseases, and the diseases of rice are further aggravated.
Oxazosulfanyl is an insecticide developed by Sumitomo chemical Co., ltd., development code S-1587. Oxazosulfanyl has good control effect on lepidoptera, coleoptera and diptera rice pests and also has good control effect on a part of mites. Oxazosulfanyl chemical name is: 2- [3- (ethylsulfonyl) -2-pyridinyl ] -5- [ (trifluoromethyl) sulfonyl ] benzoxazole (2- [3- (ethylsulfonyl) -2-pyridinyl ] -5- [ (trifluormethoyl ] sulfonyl ] benzoxazole }), CAS accession no: 1616678-32-0. The structural formula of Oxazosulfanyl is:
。
the hydrazine inhibitor is an insect growth regulator, and has the functions of inhibiting feeding, accelerating molting, reducing spawning and the like on lepidoptera, coleopteran and dipteran larvae. The hydrazine has the main stomach toxicity effect on pests, takes effect 2-3 days after application, has long lasting period and no residue, is suitable for preventing and controlling various pests on vegetables, cabbage caterpillars, prodenia litura, plutella xylostella and the like, and has good effects on rice leaf rollers and rice armyworms. The structural formula of the food inhibiting hydrazine is as follows:
。

The compositions of the present application may be converted into conventional seed dressing formulations such as solutions, emulsions, suspensions, powders, foams, slurries or other coating materials for seeds, as well as ULV formulations.
Depending on the plant species or plant cultivars, their location and growth conditions (soil, climate, vegetative stage, nutrition), the treatment according to the application may also bring about superadditive ("synergistic") effects. Thus, for example, the following effects can be brought beyond what is actually expected: the compositions comprising oxazosulfanyl and antifeedant hydrazine which can be used according to the application have a reduced application rate and/or a broader spectrum of activity and/or an increased activity, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, larger fruits, higher plant heights, greener leaf colour, earlier flowering, higher quality and/or higher nutritional value of the harvested products, higher sugar concentration in the fruits, better storage stability and/or processability of the harvested products.
The measurement of whether the pesticide composition has synergistic effect can be expressed by the co-toxicity coefficient (CTC) =measured toxicity index (ATI)/Theoretical Toxicity Index (TTI) ×100), and if the co-toxicity coefficient (CTC) is greater than 120, the synergistic effect (synergistic effect) is obtained; co-toxicity coefficients (CTCs) less than 80 are antagonism, and co-toxicity coefficients (CTCs) are additive between 80-120.
Compared with the prior art, the insecticidal composition/preparation has the beneficial effects that: (1) can play a role in synergy; (2) can delay the generation of drug resistance; (3) improving safety to crops; and (4) the two pesticides are compounded, so that the medication cost is reduced, and the labor force is saved.

According to the activity of the medicament, 6 series of mass concentrations are set according to an equal ratio method: 5. 2.5, 1.25, 0.625, 0.3125, 0.15625 mg/L. The liquid medicine amount per mass concentration is not less than 50 and mL. The liquid medicine is injected into the surface of the prepared feed to prepare the feed containing the medicine, the feed containing the medicine is cut into pieces, the pieces are placed in a plastic culture dish with the diameter of 9 cm, 10-20 heads of stem borers are inoculated, each treatment is repeated for 3 times, the test insects are transferred to the normal condition for feeding, and the treatment without the medicine is used as a blank control.
After treatment 72 h, the death of the test insects was checked and the total number of insects and the death were recorded, respectively.
From the survey data, the corrected mortality of each treatment was calculated, and the co-toxicity coefficient (CTC value) of the blends was calculated according to the grand cloud method. Analyzing by statistical analysis software SAS, data processing software DPS, etc., and calculating LC of each agent 50 、LC 90 The b value (standard error) equivalence and the 95% confidence limit.
Mortality (%) = number of dead insects (head)/total number of treated insects (head) ×100
Corrected mortality (%) = (treatment mortality-blank mortality)/(100-blank mortality) ×100
Toxicity index = standard agent LC 50 value/Single dose LC 50 Value x 100
LC of observed virulence index (ATI) =standard agent 50 LC of value/mixture 50 Value x 100
Theoretical Toxicity Index (TTI) =toxicity index of a single dose×proportion of a single dose in mixture+toxicity index of B single dose×proportion of B single dose in mixture
Co-toxicity coefficient (CTC) =measured virulence index (ATI)/theoretical virulence index (TTI) ×100
CTCs greater than 120 exhibit potentiation, CTCs less than 80 exhibit antagonism, CTCs between 80 and 120 exhibit additive effects.
