Problems solved by technology

However, with the extensive abuse of chemical sterilants, the control effect is getting worse; in addition, some researchers have used genetic engineering to study disease-resistant plants, but due to various reasons, the popularization or practical application effect is not ideal, resulting in cotton wilt It has become one of the hidden dangers of my country's cotton planting industry. When a local outbreak occurs, it will cause great losses to the growers in the area

Embodiment 1

[0034] A method for preventing and controlling cotton verticillium wilt, comprising the following steps:

[0035] (1) Seed pretreatment: the seeds are sterilized, germination-promoting and antibacterial treatments in sequence;

[0036] (2) Intervention at the flowering stage: After the seeds germinate to the flowering stage, add a mixture of trace elements and microbial agents to the soil;

[0037] (3) Eliminate weeds and insects, and clean up diseased plants in time.

[0038] Step (1) pretreatment is as follows: the cotton seeds are placed in 500-fold diluted mass ratio of 50% fenflum, soaked for 5 minutes, rinsed with pure water, placed in a final concentration of 0.05mg / ml6-BA solution, soaked 6h; finally, the seeds were soaked in traditional Chinese medicine control agents for 6h, and then dried for later use.

[0039] In order to further optimize the technical scheme: the raw materials of the traditional Chinese medicine control agent are composed of the following compo...

Embodiment 2

[0048] A method for preventing and controlling cotton verticillium wilt, comprising the following steps:

[0049] (1) Seed pretreatment: the seeds are sterilized, germination-promoting and antibacterial treatments in sequence;

[0050] (2) Intervention at the flowering stage: After the seeds germinate to the flowering stage, add a mixture of trace elements and microbial agents to the soil;

[0051] (3) Eliminate weeds and insects, and clean up diseased plants in time.

[0052] For further optimizing the technical scheme: step (1) pretreatment is followed successively: the cotton seed is placed in 500 times of dilute mass ratio 50% fenzam, after soaking for 6min, place final concentration 0.04mg / ml after rinsing with pure water6 -BA solution, soaked for 7 hours; finally soaked in traditional Chinese medicine control agent for 8 hours, and dried for later use.

[0053] In order to further optimize the technical solution: the raw materials of the traditional Chinese medicine cont...

Embodiment 3

[0062] A method for preventing and controlling cotton verticillium wilt, comprising the following steps:

[0063] (1) Seed pretreatment: the seeds are sterilized, germination-promoting and antibacterial treatments in sequence;

[0064] (2) Intervention at the flowering stage: After the seeds germinate to the flowering stage, add a mixture of trace elements and microbial agents to the soil;

[0065] (3) Eliminate weeds and insects, and clean up diseased plants in time.

[0066] Step (1) pretreatment is as follows: the cotton seeds are placed in 500-fold diluted mass ratio of 50% fenflum, soaked for 5 minutes, rinsed with pure water, placed in a final concentration of 0.045mg / ml6-BA solution, soaked 6.5h; finally, the seeds were soaked in traditional Chinese medicine control agents for 7h, and then dried for later use.

[0067] In order to further optimize the technical solution: the raw materials of the traditional Chinese medicine control agent are composed of the following ...

Abstract

The invention discloses a cotton verticillium wilt prevention and treatment method, and belongs to the technical field of crop disease prevention and treatment. The method comprises the following steps of: carrying out seed pretreatment, namely sequentially carrying out sterilization, germination promotion and antibacterial treatment on seeds; intervening in the flowering phase: after the seeds germinate to the flowering phase, adding a trace element mixture and a microbial agent into the soil; and conducting weeding and deinsectization, and clearing diseased plants in time. Through seed pretreatment, the disease resistance of the seeds is improved, and nutrient absorption of plants is further guaranteed. Rooting, nitrogen fixation and strengthening promotion effects are achieved with theassistance of the microbial agent, the pathogenic bacterium infection capacity can be jointly inhibited, and the morbidity is reduced.

Description

technical field [0001] The invention relates to the technical field of crop disease prevention and control, in particular to a cotton verticillium wilt control method. Background technique [0002] Cotton wilt is a common disease in cotton planting period. The pathogen is a fungus named Fusarium oxysporum (wilting type), which mainly damages the vascular bundles and other parts of cotton, causing the leaves to die or fall off. Depending on the location of their hazards, different specific names can also be used to refer to them. [0003] The disease can be controlled by spraying pesticides or planting management. However, with the extensive abuse of chemical sterilants, the control effect is getting worse; in addition, some researchers have studied disease-resistant plants through genetic engineering, but due to various reasons, the popularization or practical application effect is not ideal, resulting in cotton wilt It has become one of the hidden dangers of my country's ...
