Embodiment 1

[0040] Get stearyl ethanolamine (SEA) 0.69g (purchased from SIGMA company), SEA is completely dissolved in the ethanol solution of 137.6mL, guarantees that no SEA is separated out; Slowly add the water of 154.9mL again, and mixed solution is mixed, finally Add 7.5mL of organosilicon solution to the mixed solution, stir evenly to obtain the preparation.

[0041] Get 100 milliliters of the preparation of the present invention, add 10 liters of clear water and mix evenly, evenly spray on the surface of tomato blades whose seedling age is five leaves and one heart in the evening, until the leaves are wet, continue to spray for 2 days, use the tomato plants sprayed with clear water as control. Randomly take tomato leaf samples sprayed with formulations and controls, use Trizol and SuperscriptII kits produced by Invitrogen, USA to extract, purify, and reverse-transcribe cDNA, and then use the Step ONE Plus Real-TimePCR System produced by Applied Biosystems, USA The instrument and t...

Embodiment 2

[0045] Weigh stearyl ethanolamine (SEA) 0.197g (SEA is purchased from SIGMA company), measure ethanol solution 39.3mL; SEA is completely dissolved in the ethanol solution, then slowly add 254.7mL of water, and the mixed solution is mixed evenly, Ensure that no SEA is precipitated; finally add 6.0 mL of organosilicon solution to the mixed solution, stir evenly to obtain the preparation.

[0046] Get 100 milliliters of the preparation of the present invention, add 10 liters of clear water and mix evenly, evenly spray on the surface of tomato blades whose seedling age is three leaves and one heart in the evening, until the leaves are wet, continue to spray for 2 days, use the tomato plants sprayed with clear water as control. The Botrytis cinerea pathogen was sprayed and inoculated on the plants treated with the preparation and the control, so that the suspension of the pathogen was evenly distributed on the leaves, and the inoculation concentration of the Botrytis cinerea pathog...

Embodiment 3

[0049] Get stearyl ethanolamine (SEA) 0.98g (purchased from SIGMA company), SEA is dissolved in the ethanol solution of 196.5% fully, guarantees that no SEA is separated out; Slowly add the water of 94.5mL again, and mixed solution is mixed, finally to Add 9.0 mL of organosilicon solution to the mixed solution, stir evenly to obtain the preparation.

[0050] Choose two adjacent plastic greenhouses with completely consistent cultivation technology and management, use the preparation of the present invention for the treatment shed in the rainy season at the end of spring, take 200 milliliters of the preparation of the present invention, add 20 liters of clear water and mix evenly, divide the preparation in the morning and evening Spray evenly twice on the surface of tomato leaves with a seedling age of seven leaves and one heart until the leaves are wet, and continue spraying for 2 days. The control booths were only sprayed with the same volume of water. Ten days later, the dis...

Abstract

The invention discloses application of stearoyl ethanolamine in plant botrytis resistance improvement and application of the stearoyl ethanolamine in preparing a preparation for improving plant botrytis resistance. According to the preparation taking the stearoyl ethanolamine as a main active ingredient, resistance of plants to botrytis can be enhanced remarkably through induction of signal paths of jasmonic acid and ethylene in plant bodies, and economic losses of the plants due to the botrytis can be reduced. By the preparation, simplicity and easiness in plant botrytis prevention and treatment are achieved, cost is low, growth of botrytis cinerea pathogenic bacteria on leaves and spread of diseases can be delayed and inhibited remarkably, and resistance of the plants to the botrytis can be improved greatly.

Description

technical field [0001] The invention relates to the field of phytochemical protection, in particular to the application of stearyl ethanolamine in improving plant gray mold resistance. Background technique [0002] Botrytis cinerea caused by Botrytis cinerea is a worldwide disease. Under suitable conditions such as low temperature and high humidity, the germinated conidia spread with airflow, irrigation water and agricultural tools. and infects from host wounds or dead tissue. Botrytis cinerea is a typical epidemic disease, with a short incubation period, rapid prevalence and intermittent outbreaks, and a wide range of hosts, especially on tomatoes. Botrytis cinerea can infect tomato leaves, stems, flowers, fruits and other tissues, resulting in severe reduction in yield and income, or even no harvest. It has also become a restrictive obstacle to tomato production in my country and even in the world. In addition to tomatoes, Botrytis cinerea can also infect more than 200 c...
