Embodiment 1

[0043] 1. Preparation of preparations

[0044] Take 2.54g of sulfopeptine-α (PSKα) (purchased from French NeoMPS company); slowly add 294.0mL of water, and mix the mixed solution evenly, and finally add 6.0mL of organosilicon solution to the mixed solution, stir evenly , to obtain the preparation.

[0045] 2. Application and testing of preparations

[0046] Take 100 ml of the above preparation, add 10 liters of water, mix well, and spray evenly on the surface of tomato leaves with four leaves and one heart at the seedling age in the evening until the leaves are wet, and continue spraying for 2 days. control.

[0047] Botrytis cinerea was sprayed and inoculated on the plants treated with the above preparation and the control plants, so that the suspension of the pathogen was evenly distributed on the leaves, and the inoculation concentration of the gray mold pathogen was 2×10 5 Spores / ml. All the plants treated above were placed at 25°C, 95% humidity, 12h light / 12h dark, an...

Embodiment 2

[0051] 1. Preparation of preparations

[0052] Take 2.03g of sulfopeptine-α (PSKα) (purchased from NeoMPS, France); slowly add 292.5mL of water, and mix the mixed solution evenly, and finally add 7.5mL of organosilicon solution to the mixed solution, stir evenly , to obtain the preparation.

[0053] 2. Application and testing of preparations

[0054] Take 100 ml of the above preparation, add 10 liters of water, mix well, and spray evenly on the surface of tomato leaves with four leaves and one heart at the seedling age in the evening until the leaves are wet, and continue spraying for 2 days. control.

[0055] Botrytis cinerea was sprayed and inoculated on the plants treated with the above preparation and the control plants, so that the suspension of the pathogen was evenly distributed on the leaves, and the inoculation concentration of the gray mold pathogen was 2×10 5 Spores / ml. All the plants treated above were placed at 25°C, 95% humidity, 12h light / 12h dark, and the l...

Embodiment 3

[0059] 1. Preparation of preparations

[0060] Take 3.05g of sulfopeptine-α (PSKα) (purchased from French NeoMPS company); slowly add 291.0mL of water, and mix the mixed solution evenly, and finally add 9.0mL of organosilicon solution to the mixed solution, stir evenly , to obtain the preparation.

[0061] 2. Application and testing of preparations

[0062] Select two adjacent plastic greenhouses with exactly the same cultivation technology and management, and use the above preparation for the treatment shed, take 200 ml of the preparation, add 20 liters of water, mix well, and spray evenly on the seedlings twice in the morning and evening The leaf surface of the tomato with seven leaves and one heart was continuously sprayed for 2 days until the leaves were wet; while the control shed was only sprayed with the same volume of water.

[0063] After 7 days, the disease incidence of 60 tomato plants in the treatment shed and the control shed were randomly counted, and the healt...

Abstract

The invention discloses application of phytosulfokine-alpha to improvement on plant resistance to botrytis cinerea and application of the phytosulfokine-alpha to preparation of a preparation for improving the plant resistance to the botrytis cinerea. The preparation prepared by using the phytosulfokine-alpha as a main active component can significantly enhance the plant resistance to the botrytis cinerea through induction of a calcium signal path in a plant so as to reduce the economic losses caused by botrytis cinerea infection. Application of the preparation provided by the invention to control plant botrytis cinerea is simple and easy and relatively low in cost; growth of botrytis cinerea on leaves and disease spread can be significantly delayed and inhibited, so that the plant resistance to the botrytis cinerea is greatly improved.

Description

technical field [0001] The invention relates to the technical field of phytochemical protection, in particular to the application of phytosulfopeptin-α in improving plant gray mold resistance. Background technique [0002] The cultivated area and total output of tomato in my country rank first in the world, and the demand and planted area are increasing year by year. The development of various bacterial, viral and fungal diseases is also more rampant, causing extremely serious economic losses in tomato production. Fungal diseases are the diseases with the largest number of known disease types, accounting for about 80-90% of the disease types, and have the most symptom types, appearing in various parts of plants. Botrytis cinerea is one of the most important fungal diseases. It is caused by Botrytis cinerea of ​​the subphylum Deuteromycota. Irrigation water and agricultural tools spread, and infect from host wounds or dead tissues, leading to crop yield reduction or even fai...
