A stored grain insect repellent and antifungal agent containing cinnamon oil

technical field

The invention belongs to the field of grain storage, and in particular relates to an insect repellent and antifungal agent for stored grain containing cinnamon oil.

Background technique

Grain is the food with the largest output in the world. my country is a large grain-producing country. In 2007, it exceeded 500 million tons. With the continuous increase of grain production, the number of grains that are moldy due to drying and drying in time and improper storage in the country every year One billion kilograms, accounting for about 1.5%-3% of the country's total grain output. Grain mildew will not only cause huge economic losses, but also produce toxins due to mold, posing a threat to human and livestock health. The process of grain mildew is also a process of producing toxins. Mycotoxins have serious harm to humans, which is manifested in that it can have long-term effects on the human body, especially causing immune damage and cancer. However, because its harm to the human body is not as obvious as virus and microbial contamination, the public still does not pay enough attention to the impact of mycotoxins. It has been found that there are more than 200 kinds of mycotoxins in the natural world, and they are arranged in order of importance and harm of mycotoxins into aflatoxin (Aflatoxin, AF), storage aspergillus toxin (0chratoxinA, 0A), and single-terminal mycotoxins. Toxins (Trichothecenes), Zearalenone (Zearalenone, ZEA). Mycotoxins have two types of toxicity, one is to cause damage, and the other is to cause cancer. The second is cytotoxicity, which has the effect of destroying plasma membrane and cellular enzymes. The effect of fungicide application on toxins is an important indicator of our fungicide screening work.

The food loss in the world is about 10% of the total output, of which the mildew loss due to microbial hazards accounts for 2% to 3%, which is only a quantitative estimate, and the quality damage is difficult to summarize . Therefore, while ensuring the quantity of stored grains is real, it is of great significance to ensure the quality of stored grains to prevent grain mildew. In order to prevent the grain from growing moldy during storage, the most effective way is to add anti-fungal agent. At present, the antifungal agents commonly used in grain storage mainly include sodium diacetate, propionic acid and its salts, sorbic acid and its salts, fumaric acid and its phenolics, and compound antifungal agents. However, a single-component antifungal agent cannot inhibit all molds. The compound antifungal agent is composed of several antifungal agents with synergistic effects in a certain proportion. Its synergistic and synergistic effects can Overcome the limitations of single-component antifungal agents in antifungal efficacy, thereby expanding the efficacy and scope of antifungal agents to achieve the purpose of antifungal. However, at present, compound antifungal agents are mainly composed of chemical agents. Although the antifungal effect is good, there are safety problems. An ideal bactericide and antifungal agent should meet the following conditions: high efficiency, broad spectrum, low toxicity, long-acting, stable, low price, easy to use, good compatibility with other additives, no pollution, and easy biodegradation. Therefore, safe, environment-friendly, non-polluting and effective mildew-proof grain anti-fungal agents are people's constant pursuit.
