Embodiment 1

[0017] Embodiment 1 fumigation toxicity assay

[0018] Preparation of allyl isothiocyanate and allicin compound: the mass ratio of AITc, allicin and acetone is 9:1:30, 7:1:30, 5:1:30, 3:1 :30, 1:1:30, 1:3:30, 1:5:30, 1:7:30, 1:9:30 for preparation.

[0019] Jar-mouth fumigation: hang a 3cm×11cm piece of filter paper in the center of a 1000mL jar, insert 30 test insects first, and drop a certain concentration of the compound solution on the filter paper with a pipette gun, and then quickly Cover the bottle cap to seal the mouth of the bottle. Each treatment was repeated 3 times, and solvent control and blank control were set at the same time. Five fumigation concentrations were set for each proportion of the mixed solution, and each treatment was placed in a constant temperature and humidity chamber (temperature: 28°C ± 1°C, humidity: 75% ± 5%) for testing. Investigate the number of knocked-down insects after 72 hours, open the bottle cap after 72 hours, pour the test insect...

Embodiment 2

[0038] Embodiment 2 allyl isothiocyanate and allicin compound agent is used for empty warehouse fumigant

[0039] Place the container of the fumigant containing allyl isothiocyanate and allicin compounding agent in the empty chamber, said compounding agent is composed of allyl isothiocyanate, allicin, ethyl acetate by 1 : The ratio of 2:10, the sum of the mass of allyl isothiocyanate and allicin in the compound agent used for each cubic meter of storage capacity is 2-8g for fumigation, which can effectively carry out empty warehouse disinfection. The control effect of corn beetle, corn beetle, corn beetle, corn beetle, and rusty red flat beetle on stored grain pests can reach more than 95%.

Embodiment 3

[0040] Embodiment 3 allyl isothiocyanate and allicin composite agent are used for antibacterial fumigant

[0041] Allyl isothiocyanate and allicin compound (the compound is composed of allyl isothiocyanate, allicin, and ethyl formate in a ratio of 1:3:60), calculated on the basis of each ton of grain When the sum of the mass of allyl isothiocyanate and allicin is 8-20g, it can effectively inhibit a variety of stored grain molds, and is effective against various molds such as Aspergillus oryzae, Aspergillus flavus, Penicillium, and Aspergillus niger. The antibacterial rate reaches more than 95%.

Abstract

The invention discloses an allyl isothiocyanate and allicin compound and an application thereof. The compound is prepared from allyl isothiocyanate (AITc), allicin and an organic solvent, and can be applied in food storage as a fumigation agent for food storage. The allyl isothiocyanate and allicin compound disclosed by the invention has an obvious synergistic effect; the insecticidal toxicity is obviously higher than that of any single dosage; the insecticidal bacteriostatic spectrum is obviously expanded; the control effect on pests, such as tribolium castaneum, oryzae philus surinamensis, sitophilus zeamais, grain moth and cryptolestes ferrugineus, in stored grain reaches over 95%; the bacteriostasis rate on a plurality of stored grain mildews such as aspergillus oryzae, aspergillus flavus, blue mould and aspergillus niger reaches over 95%; and the allyl isothiocyanate and allicin compound has relatively high cost advantages, economic benefits and relatively good control effect.

Description

technical field [0001] The invention belongs to the technical field of grain storage, and in particular relates to a compound agent of allyl isothiocyanate and allicin and its application. Background technique [0002] Food is the most basic means of subsistence needed by human beings to survive. The food issue is a top priority related to a country's national economy and people's livelihood, and is of great significance to a country's security and stability. At present, under the situation that the world's cultivated land resources are limited and the demand for grain consumption continues to increase, strengthening the safe storage of grain is an important measure to ensure national food security. In the process of grain storage, due to the influence of many factors, both the quantity and quality of grain can cause the loss of stored grain. Among them, insect damage and mildew are one of the important factors causing serious loss of grain during storage. [0003] Stored ...
