Embodiment 1

[0053] 1. Separation and extraction of yeast cell extract

[0054] 1) Dissolve the yeast cells in 1mol / L NaOH (W:V=1:2), react at 75°C for 6 hours, repeat once, wash with water until neutral, and obtain a brown viscous extract;

[0055] 2) The extract was dissolved in 1 mol / L HCl (W:V=1:1), reacted at 30°C for 2 hours, washed with water until neutral to obtain light brown crude extract, decolorized and degreased with ethanol, dehydrated and dried with ether to obtain The white powder is the yeast cell extract required for the preparation of the plant disease resistance inducer containing the yeast cell extract.

[0056] 2. The prepared yeast cell extract is prepared into a water suspension containing 40% yeast cell extract-plant disease resistance inducer according to the following ratio:

[0057] Yeast Cell Extract 40%

[0058] Farm Milk 0204 3.6%

[0059] Sodium lignosulfonate (or calcium lignosulfonate) 3%

[0060] Xanthan Gum 0.15%

[0061] White clay 2.4-3.6%

[006...

Embodiment 2

[0066] 1. The separation and extraction of yeast cell extract is the same as [Example 1]

[0067] 2. The prepared yeast cell extract is prepared into a water suspension containing 50% yeast cell extract-plant disease resistance inducer according to the following ratio:

[0068] Yeast Cell Extract 50%

[0069] Farm Milk 0204 3%

[0070] Sodium lignosulfonate (or calcium lignosulfonate) 2.5%

[0071] Xanthan Gum 0.10%

[0072] White clay 2-3%

[0073] Isoamyl Alcohol 0.5%

[0074] Glycerol 2-3%

[0075] Water 37.90-39.90%

Embodiment 3

[0077] 1. The separation and extraction of yeast cell extract is the same as [Example 1]

[0078] 2. The prepared yeast cell extract is prepared into a water suspension containing 60% yeast cell extract-plant disease resistance inducer according to the following ratio:

[0079] Yeast Cell Extract 60%

[0080] Farm Milk 0204 2.4%

[0081] Sodium lignosulfonate (or calcium lignosulfonate) 2%

[0082] Xanthan Gum 0.05%

[0083] White clay 1.6-2.4%

[0084] Isoamyl Alcohol 0.4%

[0085] Glycerol 1.6-2.4%

[0086] Water 30.35-31.95%

[0087] The present invention will be further illustrated below by test examples.

Abstract

A disease resistant inducing agent for plants contains beta-1,3 glocosan, extract of yeast cell, wetting agent and disperser.

Description

technical field [0001] The invention relates to a yeast cell extract, more precisely a plant disease resistance inducer containing fungal polysaccharides and its preparation and application. Background technique [0002] The occurrence of various diseases can reduce the yield of crops by 30-40%. At present, the main method of plant disease prevention and control is the use of chemical pesticides and disease-resistant varieties. Although chemical pesticides can quickly and effectively kill pathogens, there are a series of problems such as environmental pollution, pesticide residues, pathogen resistance, and destruction of ecological balance. question. Disease-resistant varieties are an effective measure to prevent and control diseases, especially with the rapid development of genetic engineering, the means of breeding disease-resistant varieties has been increased, but this method has a long cycle and high cost, and many diseases cannot be solved by disease-resistant varieti...
