Embodiment 1

[0055] Embodiment 1 The production of 8% AITC and 2% benzyl isothiocyanate (BITC) composition oil

[0056] Accurately and quantitatively weigh the AITC original drug with a content of 94% (note: the contents in the present invention are all percentages by weight) (note: the isothiocyanate original drug and extract in the present invention are from Wuhan Leliji Biotechnology Co., Ltd. Co., Ltd.) 4.25kg, then weighed 25kg of 4% BITC extraction mother liquor, and fully mixed in a 2M3 blending tank. Add 0.5 kg of accurately weighed ascorbic acid, and mix well again. Then accurately drop 10.125kg of ethyl acetate and 10.125kg of vegetable oil into the blending tank, fully mix, and continue to stir for 1 hour. The oil preparation product of 50kg AITC and BITC composition is formulated.

[0057] Sampling analysis showed that the content of AITC in the product was 8.01%, and the content of BITC was 2.00%. The product is divided into aluminum cans coated with barrier material, each ...

Embodiment 2

[0058] Embodiment 2 Production of 11.7% AITC and 1.3% benzyl isothiocyanate composition aqueous emulsion

[0059] Accurately weigh 249kg of AITC with a content of 94%, 28.9kg of benzyl isothiocyanate with a content of 90%, and 20kg of ascorbic acid, and fully stir them evenly in a blending tank. Then quantitatively add 200kg of agricultural emulsifier TX-10, 366kg of ethyl acetate, 350kg of vegetable oil into the blending tank, add 786.1kg of water, stir while adding, after all materials are added, continue to stir with a mixer for 1 hour, and prepare 2 tons of AITC and BITC composition oil products.

[0060] Sampling test results show that the product contains 11.98% of AITC and 1.30% of benzyl isothiocyanate, and finally obtains a composition product with an effective component content of 13.3%. The product is packed in a 500mL glass bottle and the mouth of the bottle is sealed ,put on label.

Embodiment 3

[0061] Example 3 Production of 1% AITC and 6% 2-phenylethyl isothiocyanate composition oil

[0062] Accurately and quantitatively weigh 50kg of AITC extraction mother liquor with a content of 20%, and then weigh 66.7kg of benzyl isothiocyanate with a content of 90%. 3 Mix thoroughly in the mixing tank. Add 30kg of accurately weighed ascorbic acid, and mix well again. Then accurately drop 450kg of ethyl acetate and 450kg of vegetable oil into the blending tank and mix thoroughly. Stirring was continued for 3 hours. The oil preparation product of 1 ton of AITC and BITC composition was formulated.

[0063] Sampling analysis showed that the content of AITC in the product was 1.00%, and the content of BITC was 5.99%. The product is divided into aluminum cans coated with barrier material, 5kg per can, 200 cans in total. The mouth of the jar is sealed, and a label is attached to be a composition oil product with an effective component content of 7%.

Abstract

The invention provides a composition of aromatic isothiocyanate and allyl isothiocyanate, and the weight ratio of the two is 1:9-9:1. The invention further provides an application of the composition in preparation of pesticide fumigants for controlling soil-borne pathogens and soil nematodes. The composition has the advantages that the composition of the aromatic isothiocyanate and the allyl isothiocyanate takes the allyl isothiocyanate as a main active ingredient and takes the aromatic isothiocyanate as a synergistic ingredient, and can prolong the action time of a medicament, improve the control effect, realize the significant synergy, simultaneously reduce the dosage of the medicament, reduce the environmental pollution, be more environmentally friendly and be safe to people and animals.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a composition of aryl isothiocyanate and allyl isothiocyanate and its application in the preparation of pesticide fumigants. Background technique [0002] Isothiocyanate (ITCs) compounds widely exist in Brassicaceae plants, especially Brassica and Horseradish plants have considerable output. Different types of isothiocyanate compounds are contained in different plants, most of which contain allyl isothiocyanate (AITC), aryl isothiocyanate, propyl isothiocyanate Esters, 4-Prenyl Isothiocyanate, 5-Methylthiopentyl Isothiocyanate, 6-Methylthiohexyl Isothiocyanate, 7-Methylthioheptyl Isothiocyanate Various types of ITCs such as cyanate esters coexist in plant tissues. [0003] The research found that in addition to the seasoning effect, ITCs also have a variety of biological activities, which can effectively kill or inhibit bacteria, such as Vibrio cholerae, Salmonella typhi, Staphylococc...
