Embodiment 1

[0043] Formula (parts by weight): 27 parts of dichlorvos, 30 parts of ammonium nitrate, 32 parts of corn cob, 3 parts of bentonite

[0044] Preparation Process:

[0045] 1. Sieve each combustion aid, fuel, and auxiliary raw material separately to remove the impurities;

[0046] 2. Adopt airflow crushing and supporting mixing equipment to crush various raw materials respectively;

[0047] 3. Dry the crushed raw materials in a special fire-proof drying room until moisture is removed;

[0048] 4. After measuring various raw materials separately, put them into a high-efficiency mixer and mix them evenly;

[0049] 5. After the product passes the inspection, put it into a paper bag, then put it into a polyethylene film packaging bag, and seal it.

[0050] 6. When using, mix dichlorvos emulsifiable concentrate with the above products evenly.

Embodiment 2

[0052] Formula (parts by weight): 25 parts of dichlorvos, 25 parts of potassium nitrate, 30 parts of corn cob, 2 parts of kaolin

[0053] The preparation process is the same as in Example 1.

Embodiment 3

[0055] Formula (parts by weight): 20 parts of dichlorvos, 15 parts of ammonium nitrate, 15 parts of potassium nitrate, 35 parts of straw powder, 5 parts of bentonite

Abstract

The saef dichlorvos smoke agent consists of dichlorovos 20-27 weight portions, combustion promoter 25-35 weight portions and fuel 30-35 weight portions. The combustion promoter is one or several selected from ammonium nitrate, potassium nitrate, sodium nitrate, potassium perchlorate and potassium permanganate; and the fuel is one or several selected from corn cob, cow manure powder, straw and bagasse. The said agent is bagged, and thus safe without self combustion, low in cost and favorable to environment protection, and its package isolates moisture effectively.

Description

Technical field: [0001] The invention relates to a novel pesticide smoke agent, in particular to a pesticide-safe dichlorvos smoke agent. Background technique: [0002] Since the 1980s, with the development of agricultural protected areas, my country has begun to study special smoke agents for protected areas, and tablet and granule smoke agents have appeared. [0003] In the smoke agent of the prior art, stronger oxidizers (such as potassium chlorate used in Chinese patent 1337155A) are often used, which are prone to "spontaneous combustion" fire accidents. According to incomplete statistics in Beijing, Henan and other places, there were as many as seven accidents of spontaneous combustion of smoke agents between 1984 and 1986, and three of them caused large economic losses, which brought great economic losses to the production, storage, transportation and application of smoke agents. great difficulties and obstacles. [0004] The fuel in the smoke agent of the prior art ...
