Method for preventing and treating wheat fungal diseases using biological preparation, plant stress-resistance chemical inducer

Abstract

The present invention discloses a method for preventing fungal wheat diseases by using biological agent and chemical resistance inducer. The method is capable to overcome the defects of other methods. The method includes the following steps, step 1:during plowing before sowing, 300g soil activator Medina for each mu of soil is mixed with proper amount of water and sprayed into the plowed soil; proper amount of plant chemical resistance inducer Isolane regulator is used for seed dressing; step 2: during the tillering stage of the wheat, 20ml Isolane regulator is used for one mu of leaf sprinkling or root irrigating during the tillering stage of the wheat; step 3: during the greening stage, 20ml Isolane regulator is used to sprinkle one mu of foliages once; step 4: during the grouting stage, another 20ml Isolane regulator is used to sprinkle the foliages once; according to the practice, the diseases seldom take place during the fully growing stage, and the average yield increases by about 30 percent.

Description

1. Technical field: [0001] The invention relates to a method for preventing wheat diseases, in particular to a method for preventing and treating fungal diseases of wheat by using biological agents and plant stress-resistant chemical inducers. 2. Background technology: [0002] At present, the main diseases that threaten the growth of wheat most are; root rot, rust, sheath blight, total erosion, scab, etc. are all fungal diseases. Due to the large amount of inorganic chemical fertilizers used by farmers, the soil is compacted, the permeability is poor, and the beneficial microbial community in the soil is very weak. Soil-borne diseases of crops are serious year by year. The above-mentioned diseases are not effective with a single chemical control measure. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a kind of easy and simple operation, the method that utilizes biological agent, plant anti-adversity chemical inducer to prevent an...
