Problems solved by technology

Biological agents that have been discovered so far include 1,2-benzisothiazolin-3-one (BIT), benzothiadiazole (BTH), brassinolides (BRs), etc. Studies have shown that BIT, BTH The application of salicylic acid (SA) can effectively induce the synthesis of salicylic acid (SA), and induce the occurrence of induced resistance (SAR) in plant systems, thereby improving the resistance of plants to bacterial and viral diseases, and BRs have been found to be broad-spectrum Sexual resistance preparations have good effects in adversity stresses such as high temperature and low temperature, but have no obvious effect in fungal diseases, so the research on biologically active factors for fungal diseases is still relatively blank

Embodiment 1

[0038] Weigh 1.53g of decanoyl homoserine lactone (DHL) (DHL is purchased from SIGMA), measure 440.4mL of acetonitrile solution; completely dissolve DHL in the acetonitrile solution, then slowly add 134.4mL of water, and mix the mixed solution Uniform, ensure that no DHL is precipitated; finally add 25.2mL of organosilicon solution to the mixed solution, stir evenly to obtain the preparation.

[0039] Get 60 milliliters of the preparation of the present invention, add 10 liters of clear water and mix evenly, in the early morning and in the evening, spray evenly on the surface of the tomato blades whose seedling age is five leaves and one heart, until the leaves are wet, and continue to spray for 3 days. The tomato leaves were picked, and the spot treatment of the gray mold pathogen was carried out, and the inoculation concentration of the pathogen was 2×10 5 Spores / ml, spot the spore suspension of Botrytis cinerea evenly, and evenly distribute it on the leaves, 5 spots on each...

Embodiment 2

[0041] Weigh 1.59g of decanoyl homoserine lactone (DHL) (DHL is purchased from SIGMA), measure 469.8mL of acetonitrile solution; completely dissolve DHL in the acetonitrile solution, then slowly add 100.2mL of water, and mix the mixed solution Uniform, ensure no DHL precipitation; finally add 30mL of organic silicon solution to the mixed solution, stir evenly to obtain the preparation.

[0042] Take 38.5 milliliters of the preparation of the present invention, add 20 liters of clear water and mix evenly, and spray evenly on the surface of the tomato leaves whose seedling age is three leaves and one heart twice in the early morning and evening until the leaves are wet, and continue spraying for 2 days. The tomato leaves were picked, and the spot treatment of the gray mold pathogen was carried out, and the inoculation concentration of the pathogen was 2×10 5 Spores / mL, the gray mold spore suspension was evenly distributed on the leaves, with 5 spots on each leaf, with a volume o...

Embodiment 3

[0044] Weigh 1.47g of decanoyl homoserine lactone (DHL) (DHL was purchased from SIGMA), and measure 411mL of acetonitrile solution; completely dissolve DHL in the acetonitrile solution, then slowly add 169.2mL of water, and mix the mixed solution evenly , to ensure no DHL precipitation; finally add 19.8mL of organosilicon solution to the mixed solution, stir evenly to obtain the preparation.

[0045] The preparation of the present invention is applied to the roots of tomato plants by means of drip irrigation. Take 416.3 ml of the preparation of the present invention and add it to 200 liters of drip irrigation solution. Apply together in the soil of the plow layer at a depth of 20-25cm around the root of the plant until the soil is completely moist, and drip irrigation is only applied once. The verification method of the application effect of the preparation in this example is the same as that of Examples 1 and 2, and the results are as follows: the leaves of the plants drip-ir...

Abstract

The invention discloses an application of capryl homoserinelactone in the improvement of the botrytis resistance of plants, and an application of the capryl homoserinelactone in the preparation of preparations for improving the botrytis resistance of plants. The invention also discloses a preparation for improving the botrytis resistance of plants. The capryl homoserinelactone in the preparation is a plant-friendly substance, can be degraded in organisms, makes botrytis pathogens have no drug resistance after long term use, has no residuals after use, and has no toxic harms to humans, animals and environment. The preparation can substantially enhance the botrytis resistance of plants, reduces the generation of the botrytis of plants, and reduces the economic loss caused by the botrytis through inducing jasmonic acid (JA) in the plants.

Description

technical field [0001] The invention relates to the field of plant chemical protection, in particular to the application of decanoyl homoserine lactone in improving plant gray mold resistance. Background technique [0002] Vegetables and other crops are often attacked by various diseases in the process of growth and development, and the development of various fungal, bacterial, and viral diseases is very rampant, causing extremely serious economic losses in agricultural production. Among them, fungal diseases are the diseases with the most types among the known disease types, accounting for about 80-90% of the disease types, and the symptom types are also the most, appearing in various parts of plants. Botrytis cinerea is one of the more serious fungal diseases. It is caused by Botrytis cinerea. It is very easy to develop in low temperature and high humidity environment. When it occurs, it can produce lesion on plant tissue and cause tissue change. Soft, so that mycelium sp...
