Description

A kind of insecticidal composition containing fenfenozide and organophosphorus

technical field

The invention belongs to the technical field of pesticides, and relates to an insecticidal composition containing fenfenozide and organic phosphorus

Background technique

Chromafenozide chemical name: 2′-tert-butyl-5-methyl-2′-(3,5-dimethylbenzoyl)chromane-6-carbohydrazide, molecular formula: C ₂₄ H ₃₀ N ₂ O ₃ is a new type of insecticide jointly developed and put into practical use by Nippon Kayaku Co., Ltd. and Sankyo Co., Ltd. (now Sankyo Agricultural Co., Ltd.). Cyclofenozide is a dihydrazide insecticide, which inhibits the feeding of pests within a few hours after feeding, and at the same time causes the pests to molt early and cause death. Cyclofenozide not only has low toxicity to mammals, birds, and aquatic organisms, but also has no effect on arthropods, predatory acarids, spiders, Hemiptera, Coleoptera (beetles), parasites, and the environment. Therefore, it is an ideal agent in the integrated pest management system.

Chlorpyrifos (chlorpyrifos) chemical name: O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) phosphorothioate, molecular formula: C ₉ H ₁₁ Cl ₃ NO ₃ PS, chlorpyrifos It is an acetylcholinesterase inhibitor and belongs to the class of phosphorothioate insecticides. It inhibits the activity of acetylcholinesterase AChE or cholinesterase ChE in the nerves in the body and destroys the normal nerve impulse conduction, causing a series of poisoning symptoms: abnormal excitement, convulsions, paralysis, death; it has stomach poisoning, contact killing, fumigation Triple action, good control effect on various chewing and sucking mouthparts pests on rice, wheat, cotton, fruit trees, vegetables, tea trees; good mixing compatibility, can be mixed with a variety of insecticides and increase The effect is obvious. Compared with conventional pesticides, it has low toxicity and is safe to natural enemies. It is the first choice to replace highly toxic organophosphorus pesticides (such as 1605, methamidophos, omethoate, etc.); it has a wide insecticidal spectrum and is easy to combine with organic matter in the soil. Special effects on pests, lasting for more than 30 days.

Dichlorvos (dimethyl-dichloro-vinyl-phosphate) chemical name: O, O-dimethyl-O-(2,2-dichlorovinyl) phosphate, molecular formula: C ₄ H ₇ Cl ₂ O ₄ P, Dichlorvos belongs to A fast-acting broad-spectrum phosphate insecticide and acaricide. It is moderately toxic to higher animals, highly volatile, and easily enters the body of higher animals through the respiratory tract or skin. Toxic to fish and bees. It has a strong fumigation effect, stomach poisoning and contact killing effect on pests and spider mites. It has the characteristics of high efficiency, quick effect, short duration and no residue.

Malathion chemical name: O, O-dimethyl-S-[1,2-bis(ethoxycarbonyl)ethyl] phosphorodithioate, molecular formula: C ₁₀ H ₁₉ O ₆ PS _2. Malathion has good contact and certain fumigation effects, but no systemic effect. After entering the insect body, it is oxidized into malaoxon, so that it can play a more poisonous role. When entering warm-blooded animals, it is hydrolyzed by carboxylesterase that does not exist in the insect body, thus losing its toxicity. Malathion has low toxicity, short residual period, and is effective against pests with both piercing and chewing mouthparts.

Profenofos chemical name: O-(4-bromo-2-chlorophenyl)-O-ethyl-S-propyl-phosphorothioate, molecular formula: C ₁₁ H ₁₅ BrClO ₃ PS, propyl bromide Phosphorus is a moderately toxic insecticide. Non-chronic toxicity, non-carcinogenic, teratogenic, mutagenic, non-irritating to the skin, toxic to fish, birds, and bees, with contact and stomach poisoning, rapid action, and resistant to other organophosphates and pyrethroids Cotton pests are still effective, and it is an effective agent for controlling resistant cotton bollworms. In areas where resistance occurs, it can be used in combination with other pyrethroid or organophosphorus insecticides to maximize the efficacy of profenofos.

However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The compounding of ingredients from different varieties is a very common way to control resistant pests. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effect of pesticides is an additive effect, and there are very few compoundings that really have a synergistic effect, especially those with a very obvious synergistic effect and a high co-toxicity coefficient. After research by the inventor, it was found that compounding chlorpyrifos, chlorpyrifos, dichlorvos, malathion, and profenofos can produce a good synergistic effect, and about chlorpyrifos, chlorpyrifos, dichlorvos, and malathion The relevant reports on the combination of phosphorus and profenofos have not been made public yet.

The embodiment of the present invention adopts the method combining indoor virulence determination and field test. The co-toxicity coefficient (CTC) of the two agents after compounding in a certain proportion is clarified first through the indoor toxicity test. CTC<80 is an antagonistic effect, 80≤CTC≤120 is an additive effect, and CTC>120 is a synergistic effect. On this basis, field experiments were carried out.

Test method: During the test, the mother liquor of each compounding agent was diluted into five series of concentrations, and placed in beakers for later use. Using the method of soaking the leaves first and then inoculating them, the leaves of the same size that have not been exposed to any chemical agent are soaked in the prepared medicinal solution for 5 seconds, then taken out, dried naturally, put into the insect breeding box, and then connected with the larvae for testing. Breeding under the condition of 25°C, each treatment was repeated three times, and the number of test insects used in each repetition was 50. At the same time, a blank control was set up, the number of dead insects was checked at 72 hours, the mortality rate and the corrected mortality rate were calculated, and the regression equation of virulence was obtained and calculated. Calculate _LC50 values. If the control mortality rate was greater than 10%, the experiment was considered invalid. Calculated as follows:

The pest-corrected mortality rate was converted into a probability value (y), the treatment concentration (μg/m1) was converted into a logarithmic value (x), and the toxicity regression equation was obtained by the least square method, and the value of each pesticide was calculated accordingly. The co-toxicity coefficient CTC was calculated according to Sun Yunpei's formula. The calculation formula is as follows (taking chlorfenozide as the standard drug, and its toxicity index is 100):

M's Theoretical Toxicity Index (TTI) = TI of Centrafenozide × P _{of Cenfenozide} + TI of Active Active Ingredient B × P _{Active Active Ingredient B}

In the formula: M is a mixture of different proportions

P The _{effective active ingredient B} is the proportion of the effective active ingredient B in the composition

P _{ringbufenozide} is the proportion of ringbufenozide in the composition

A is selected from cyclofenozide;

B is selected from any one of the following compounds: one of chlorpyrifos, dichlorvos, malathion and profenofos.
