Embodiment 1

[0053] The production of embodiment 1 20% AITC oil agent

[0054] Accurate and quantitative weighing content is 94% (note: the contents in the present invention are all percentages by weight) AITC original drug (note: the isothiocyanate original drug and extract in the present invention are from Wuhan Leliji Biotechnology Co., Ltd. Produced by the company) 10.64kg, accurately weighed 0.5kg of ascorbic acid, put into the blending tank and fully mixed again. Then accurately drop 10.125kg of crude rapeseed oil and 28.735kg of ethyl acetate into the blending tank, fully mix, continue to stir for 1 hour, and prepare 50kg of AITC oil product.

[0055] The content of AITC was sampled and analyzed, and the result was 20.02%. The product is divided into aluminum cans coated with barrier material, each 5kg, 10 cans in total. Seal the mouth of the jar and put a label on it to be a 20% AITC oil product.

Embodiment 2

[0056] The production of embodiment 2 15% ethyl isothiocyanate soluble liquid

[0057] Accurately and quantitatively weigh 83.35kg of the original drug with a content of 90% ethyl isothiocyanate, accurately weigh 45kg of emulsifier No. 10, and 25kg of ascorbic acid, and put them into a mixing tank for mixing. Then accurately drop 189.6kg of ethyl acetate and 157.05kg of ethyl formate into the blending tank, fully mix, and continue to stir for 1 hour. Prepare the soluble liquid product of 500kg 15% ethyl isothiocyanate.

[0058] Sampling analysis wherein the content of ethyl isothiocyanate, the result was 15%. The product is divided into aluminum cans coated with barrier material, 5kg per can, 100 cans in total. Sealing the mouth of the tank and affixing a label is a 15% ethyl isothiocyanate soluble liquid product.

Embodiment 3

[0059] The production of embodiment 3 10% phenyl isothiocyanate emulsifiable concentrates

[0060] Accurately weigh 102 kg of 98% phenyl isothiocyanate technical substance, weigh 10 kg of ascorbic acid, put into the blending tank and fully mix again. Add 200kg of ethyl acetate, 200kg of castor oil, 60kg of Well205, 20kg of emulsifier No. 10, and 50kg of OP-1050kg into the blending tank. The remainder is filled with ethyl acetate and fully mixed in the blending tank. Continue stirring for 1 hour to prepare 1 ton of phenyl isothiocyanate emulsifiable concentrate.

[0061] Sampling analysis wherein the content of phenyl isothiocyanate, the result is 9.99%. The product is divided into aluminum cans coated with barrier material, 5kg per can, 200 cans in total. Seal the mouth of the jar and put a label on it to be a phenyl isothiocyanate emulsifiable concentrate product with a content of 10%.

Abstract

The invention provides application of isothiocyanate in preparation of a termite preventing and controlling agent. The isothiocyanate can be a single formulation or a compound agent and can be prepared into a plurality of formulations according to different use sites. The termite preventing and controlling agent of the invention is suitable for different occasions such as ancient architectures, modern houses, storages, embankments, dams, trees and crops, has the bioactivities of smoking, steaming, tagging out and avoiding termites, is capable of smoking, killing and repelling all kinds of termites, is friendly to the environment and safe to people, and also has the advantages of high activity, low dosage, various implementation ways, suitability and practicality, and economy and safety.

Description

technical field [0001] The invention relates to the application of a single agent or compound agent of isothiocyanate derived from Brassicaceae horseradish and Brassica plants in the preparation of termite control agent. Background technique [0002] Termites are one of the world's major pests, and their damage accounts for about 50% of the world's total land area, especially in tropical and subtropical regions. The boundary of the distribution range of termites in my country is inclines from northeast to southwest. The northernmost distribution is bounded by Dandong and Beijing in Liaoning, and the line of Medog, Tibet. 40%. In my country, the annual economic loss caused by termite damage to wooden components of houses is estimated at 1 billion to 1.5 billion yuan, and other economic losses caused by termites reach 1.7 to 2 billion yuan each year. The loss of forest trees caused by termites is also quite a lot. What's more serious is that termites can also cause embankment...
