A composition containing plant essential oil, its application and its application method

Abstract

The invention discloses a composition containing plant essential oil, an application and an application method thereof, belonging to the field of plant protection. The plant essential oil serving as an active ingredient is one or several of pericarpium zanthoxyli bungeani essential oil, zanthoxylum schinifolium essential oil and melissa essential oil; the essential oil composition is prepared from plant essential oil, a surfactant and water; the composition is used for preventing and treating bacterial vascular diseases on the plants growing in a facility cultivation environment; and when in use, the composition is diluted by water and sprayed to the plant, the spray amount is appropriate when liquid on the plant does not roll down as droplets, and then the cultivation environment is closed before ventilation. The composition can be used as a natural bacterial agent for the plant bacterial vascular diseases and has the characteristics of harmlessness to human and livestock, environment friendliness, remarkable prevention effect, rare drug resistance of pathogens and the like.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to a composition containing plant essential oil, its application and its application method. Background technique [0002] With the enhancement of people's awareness of environmental protection, under the background of increasing attention to the environment, the use of chemical pesticides with high toxicity, high residue, and serious pollution is gradually restricted, while the use of chemical pesticides that are highly effective for harmful organisms, safe for non-target organisms, easy to decompose, Environmentally friendly biopesticides are gradually recognized by the public. Botanical pesticides are plant active substances with insecticidal, bactericidal, weeding and plant growth regulation activities. With the introduction of the concept of green plant protection, research on botanical pesticides has received attention from all aspects, and government departments and scientific...

Problems solved by technology

[0007] Bacterial vascular diseases of plants are highly concealed in the early stage of the disease, and it is not easy to see with the naked eye. Once it is found that it is a bacterial disease, it is often in the middle or late stage. Increased difficulty

Because vascular pathogens live deep inside the host plant, it is extremely difficult to prevent and control vascular pathogens. Currently, there are basically no effective pesticides on the market

Moreover, some vascular pathogens can infect a broad spectrum of host plants, so conventional cultivation measures such as crop rotation are not effective in controlling

Soil exposure and chemical fumigation can be used to treat pathogens in soil, but due to the requirements of public health and environmental protection, the large-scale application of chemical fumigation is limited

Organic soil improvement can also be used to control vascular bundle diseases, but the effect of field application is unstable due to the influence of biotic and abiotic factors

In production practice, it is necessary to solve the problem of high efficiency and long-term effect of existing products, and it is urgent to develop natural fungicides for plant bacterial vascular diseases that are harmless to humans and animals and environmentally friendly
