example 1

[0023] Example 1. Preparation of magnesium ethylene bisdithiocarbamate

[0024] First react and dissolve 900 grams of prepared ethylenediamine solution and 800 grams of potassium hydroxide in the reactor, then slowly add carbon disulfide in the reactor, drop carbon disulfide until the reaction of the organic amine is complete, then add 800 Cu(NO 3 ) 2 , stirred for 30 minutes to obtain 3700 grams of ethylene bisdithiocarbamate copper aqueous product.

[0025] Grind the above-mentioned 3700 grams of raw drug water medium product with a ball mill into particles below 300 microns, add 600 grams of superfine kaolin, 600 grams of Tween-80, 250 grams of xanthan gum, 500 grams of propyl gallate, and 150 grams of sodium benzoate gram, 250 grams of glycerin, add water to 10000 grams, strengthen the stirring, and with high-speed shearing emulsifier, shear emulsification, obtain the uniformly dispersed water-emulsion suspension product of 20% copper ethylene bisdithiocarbamate .

example 2

[0026] The preparation of example 2 propenyl bisdithiocarbamate copper

[0027] First react and dissolve 900 grams of prepared isopropyldiamine solution and 800 grams of potassium hydroxide in the reactor, then slowly add carbon disulfide dropwise in the reactor, add carbon disulfide dropwise until the reaction of the organic amine is complete, then add 725 grams of Cu ( NO 3 ) 2 , reacted to obtain the aqueous medium product of the original drug of copper propenyl bis-dithiocarbamate. Thereafter, the operating procedure for preparing the dispersed aqueous emulsion suspension is the same as in Example 1.

Abstract

The present invention is new type of copper salt for killing pests and bacteria in water area, and belongs to the field of agricultural chemicals. The copper salt for killing pests and bacteria in water area is one kind of suspension and has the outstanding advantages of environment friendship, high effect of killing pests and bacteria, low toxicity and green preparation process.

Description

technical field [0001] The invention discloses a novel copper salt for insecticidal, sterilizing and disinfecting water areas, which belongs to the field of pesticides. Background technique [0002] Dithiocarbamate is a known technology as an insecticide and fungicide in agriculture, such as N, N-dimethyldithiocarbamate and ethylene bisdithiocarbamate commodity pesticides on the market There are also sales. But up to now, the above-mentioned pesticides are mainly used for crops to prevent various pests and diseases. There is no report about copper dithiocarbamate for insecticide, sterilization and disinfection of waters including pond waters, ornamental waters and aquaculture waters. [0003] The Ministry of Agriculture has issued the Ministry Order No. 31 "Aquaculture Quality and Safety Management Regulations" in August 2003. Pollution-free aquaculture in the "Regulations" has become the minimum standard in the regulations, and aquatic drugs are...
