Problems solved by technology

[0005] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a kind of pesticide composition containing diazinon and amides: by reacting parathion trichloride with n-butylamine, intermediate 1 is generated, and intermediate 1 is mixed with ammonia gas reaction to generate intermediate 2, then react alkali lignin powder, formaldehyde and sodium sulfite to generate intermediate 3, then use intermediate 3 to react with intermediate 2 to generate a modifier, and then dissolve diazinon in isopropyl After alcohol, the modifying agent is then dissolved in deionized water, and then the diazinon-isopropanol solution is modified by the modifying agent, which solves the poor effect of the existing fibendiyl and diazinon used alone The problem

Embodiment 1

[0023] This example is a method for preparing a diazine phosphate and amide a pesticide composition comprising the steps of:

[0024] Step 1: 0.3 mol of trichloromethosis, 90 g of dichloromethane is added to the four flasks mounted with a stirrer, a guide tube, and a constant pressure drip funnel, and a nitrogen 20min is transferred to the air in the four flasks. The temperature is 0 ° C, the stirring rate is 300r / min, and the n-butylamine is added to 0.5 mol: 30 g of the n-butamide solution formed in 0.5 mol: 30 g, and the control droplet rate is 1 drop / s Then, after 15 ml / min at the access rate of 15 ml / min, the reaction was continued after 2 hours, and the intermediate 1 was allowed to obtain the intermediate 1, then heated to 10 ° C, continued to enter the ammonia gas, and the constant temperature was stirred for 1 h. Then, the reaction was stopped and then stirred after 0.5 h, and the reaction product was vacuum filtered after the reaction was completed, and the filtr...

Embodiment 2

[0028] This example is a method for preparing a diazine phosphate and amide a pesticide composition comprising the steps of:

[0029]Step 1: 0.35 mol of trichloromethane, 100 g of dichloromethane is added to the four flasks mounted with a stirrer, a guide tube, and a constant voltage drop driver. The temperature is 2 ° C, and the stirring rate is 500r / min, stirring is added dropwise to the n-butylamine is dissolved in 0.55 mol: 40 g of the n-butamine solution formed in dichloromethane, and the drip rate is 1 drop / s Then, after 30 min at an entry rate of 18 ml / min, the reaction was continued after 3 hours after the dropwise addition was completed, and the intermediate 1 was allowed to heat up to 15 ° C, and the temperature was continued to enter the ammonia gas, and the constant temperature was stirred for 2h. Then, the reaction was continued after 1 h after the gas was stopped. After the reaction, the reaction product was vacuum filtered, and the filtrate was evaporated to r...

Embodiment 3

[0033] This example is a method for preparing a diazine phosphate and amide a pesticide composition comprising the steps of:

[0034] Step 1: 0.32 mol of trichloromethosis, 95 g of dichloromethane is added to the four flasks mounted with a stirrer, a guide tube, and a constant voltage drip funnel. After the temperature of 1 ° C, the stirring rate is 400 r / min, stirring is added dropwise, and the n-butylamine is dissolved in 0.52 mol: 35 g of the n-butamide solution formed in dichloromethane, and the control droplet increase is 1 drop. After the 17 ml / min passed rate of 25 min, the stirring reaction was continued after 2.5 h after 2.5 h, and the intermediate 1 was allowed to heat up to 13 ° C, and then the ammonia gas, constant temperature agitation After 1.5 h, it was stopped after the gas was transferred to 0.75 h, and the reaction product was evaporated. After the reaction was completed, the filtrate was evaporated to remove the solvent. After drying at 2.5 h, it was added t...

Abstract

The invention discloses a pesticide composition containing diazinon and amides, and relates to the field of insecticides, diazinon is modified through a modifier, amido on molecules of the modifier is protonized and then is subjected to electrostatic attraction with sulfonate radicals to form a microcapsule structure, then glutaraldehyde is added, aldehyde groups at two ends of glutaraldehyde react with amido of the modifier to realize cross-linking and curing of the microcapsule, so that the stability of diazinon is improved, a slow release effect is achieved, the dispersity of diazinon in water is improved, compounding of diazinon and flubendiamide is facilitated, the synergism of diazinon and flubendiamide is improved, the control range is expanded, a good control effect is achieved, meanwhile, amido on molecules of the modifier reacts with urease, the probability that urea reacts with urease is reduced, release of ammonia gas is reduced, the nitrogen utilization rate is increased while the environment is protected, and after the modifier is decomposed, nitrogen and phosphorus in the modifier can be used for plant growth.

Description

Technical field [0001] The present invention relates to the field of insecticides, and more particularly to a diazine phosphorcharophosphate and amide pesticide composition. Background technique [0002] Pyreoamide is a novel phthalamide insecticide, which is currently not much, actually acting on insect cytosinezil receptors, and has spectral for lepidoptera, with existing insecticides. No mutual resistance is generated, and it is very suitable for prevention and treatment of pests that existing insecticides to produce resistance. Almost all lepidoptera-like pests have good activity, and there is excellent activity on adult and larvae, and the speed of action Fast, the ending period, but the ingredient has no mocking effect, and there is no inherent effect, thereby restricting the application of the drug for a tattling or other pest; [0003] Diazine phosphorus is also known as diazine farmers, land farmers, enemy sulfur phosphorus, is an organophosphorus insecticide, pure diazi...
