CN1209025C - Prepn of pesticide synergist - Google Patents

Abstract

The present invention belongs to the technical field of chemical engineering. In order to increase the use efficiency of pesticides (especially low residue pesticides) in agricultural production, the agent uses a method of forcing pests to absorb the pesticides and simultaneously destroying the immunity of the pests, etc. to fully display the effect of the pesticides. The agent has the advantages of high light stability, simple preparation method, no contact toxicity to human and domestic animals, no damage to the growth of crops and low cost, and has strong synergistic effect on the pesticides if mixed with acidic pesticides (especially organic phosphorus pesticides). Since the agent is prepared from pure medical drugs, mass production is easy to form. The agent is favorable for popularization and can be widely used as pesticide deinsectization additives in the production of agriculture, forests, animal husbandry, etc.

Description

A kind of preparation method of pesticide synergistic agent

For the resistance of defeating insect that agricultural chemicals is produced, each state has all dropped into suitable manpower and materials, especially to the research and development of synergist.

In the past, people utilized the interior various insecticide metabolism of pest body to separate the inhibitor of toxenzyme as synergist.But because the photo-labile of synergist itself costs an arm and a leg the existence of problems such as poisoning and health, not seen widespread use all the time.

I adopt the method that insect antiemetic profit is let out through making great efforts for many years, have prepared this synergist.

This agent has changed the normal physiological function of insect, has destroyed the insect power (comprising the resistance day after tomorrow) of exempting from service, and guides agricultural chemicals directly to attack insect target sensitizing range simultaneously, reaches the desinsection purpose.

This agent compounding method:

2 parts of Reclomides

5 parts of carbachols

10000 parts in magnesium sulfate

Make this agent after three doses of mixing.This agent can be made into 150-300 times of liquid with the acid agrichemical aqueous solution, and the land for growing field crops sprays deinsectization.

When experiment, I adopt:

(1) one of the hydrochloric acid metoclopramide parenteral solution (hydrochloric Metoclopramide 10mg) of Hebei province's Handan District second pharmaceutical factory production.

(2) one of the bethanechol chloride parenteral solution (containing methylamine choline 25mg) of Baoding, Hebei province biologics factory production

(3) magnesium sulfate 50g

(4) parathion-methyl (40%) 25g

(5) phoxim (40%) 25g

(6) water 15kg

Mix, spray 3 generation cotton bollworm contain 0.5 mu in phase land for growing field crops.Observe after 24 hours, cotton bollworm one-tenth, larval mortality are greater than 95%.

Only use parathion-methyl 25g simultaneously, phoxim 25g is dissolved in the contrast of 15kg water and sprays 0.5 mu in the close cotton field of insect pest situation.Observe after 24 hours, cotton bollworm one-tenth, larval mortality are less than 30%.

This agent is compared with existing synergist has following advantage:

At first, this agent has good light stability, and cost is low, and constant uses and is difficult for producing poisoning, is difficult for harm people, animal health, and because the magnesium sulfate effect has strengthened medicament adhesive force, has reduced the medicament loss.

Secondly, pure medical use agent preparation is adopted in this agent, its preparation composition has batch process already, thereby links such as experiment production and Performance Detection have been reduced, greatly reduce production cost, and, also can simplify production routine once again again because this agent is not used in medical science, reduce production costs once more, be beneficial on a large scale and apply.

Claims (1)

1. the preparation method of a pesticide synergistic agent is characterized in that Reclomide, Lentivasan and magnesium sulfate are mixed with weight ratio at 2: 5: 10000.
