Description
Technical field
The invention belongs to agricultural technology fields, and in particular to a kind of copper agent is as inducer and in control cotton-plant pest-insects
Application technical field.
Background technique
Cotton is the important industrial crops in China, and China is maximum Cotton Production state in the world, is also the largest cotton
Country of consumption.The large area of cotton is planted, and the suckings pest such as cotten aphid, tetranychid becomes the primary pest in cotton field, to Cotton Production
Harm is serious.Currently, the prevention and treatment of cotten aphid depends on traditional chemical insecticide, due to the generation of pest resistance to insecticide, cause
Control efficiency decline, it has to improve the formulation rate of chemical insecticide, increase prevention and treatment number and be not inconsistent so that control cost rises
Close the principles and policies of current China's pesticide reduction.In recent years, the method based on chemical prevention is gradually replaced other methods.
Summary of the invention
For have not been reported in the prior art use copper agent as inducer control cotton pest the state of the art, the present invention
A kind of copper agent is intended to provide as induction and the application in control cotton field cotten aphid, tetranychid, by using copper agent, in cotton
Before aphid, tetranychid insect pest initial stage occur, the dilute solution containing copper ion is sprayed, so that cotton is generated pest-resistant secondary metabolites, reaches
To the purpose for reducing pest generation.
In order to achieve the above object, the present invention is to be achieved through the following technical solutions.
The present invention specifically provides a kind of copper agent, and the concentration of copper agent is 1 × 10-6mol/L-1×10-8mol/L。
In the present invention, copper agent uses CuCl2·2H2O is diluted with water.
In the present invention, preferably the concentration of copper agent is 1 × 10-7mol/L。
The present invention specifically provides a kind of application of copper agent as inducer in control cotton field cotten aphid, tetranychid, specific to grasp
Make step are as follows: before cotten aphid, tetranychid initial stage occur, spray copper agent, formulation rate per acre is 6 × 10-5mol-6×10-7Mol,
A copper agent is sprayed within 5-8 days again away from spraying time interval for the first time.
In the present invention, formulation rate preferably per acre is 6 × 10-6mol。
In the present invention, a copper agent was sprayed again preferably by 7 days.
By using the technical solution of above-mentioned offer, the present invention obtain it is following the utility model has the advantages that
(1) a kind of copper agent is as inducer and in control cotton field cotten aphid, the application in tetranychid, by using copper agent,
In cotten aphid, tetranychid insect pest early period of origination, certain density copper agent is sprayed as inducer, cotton is made to generate pest-resistant secondary metabolism
Substance, inducing cotton insect resistace achieve the purpose that reduce pest, and simple and easy, at low cost, before having preferable application
Scape.
(2) a kind of copper agent is as inducer and the application in control cotton field cotten aphid, tetranychid, with 1 × 10-7Mol/L's
After concentration is applied 5 days, copper agent is 15.78% to cotten aphid Revision insect recluced rate, Rectifying efficacies 32.64%, is subtracted to cotton leafworm mouthful
The rate of moving back is 14.68%, Rectifying efficacies 23.21%, 1 × 10-7The copper agent of mol/L concentration imitates prevention and treatment cotton field tetranychid and cotten aphid
Fruit is significant.
Detailed description of the invention
Nothing
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Embodiment is closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to solve

It is not limited by this.
For trying place: the Xinjiang farm San Ping Xinjiang Agricultural Univ's cotton test base；Cotton variety is that new land is No. 51 early；It covers
Film sowing.
Main agents: CuCl2·2H2O, analysis is pure, and conven-tional channels are commercially available.
Embodiment one:
The present invention specifically provides a kind of copper agent, and the concentration of copper agent is 1 × 10-6mol/L-1×10-8mol/L。
In the present invention, copper agent uses CuCl2·2H2O is diluted with water.
In the present invention, preferably copper agent concentration is 1 × 10-7mol/L。
Embodiment two:
The present invention specifically provides a kind of application of copper agent as inducer in control cotton field cotten aphid, tetranychid, specific to grasp
Make step are as follows: before cotten aphid, tetranychid initial stage occur, spray copper agent, formulation rate per acre is 6 × 10-5mol-6×10-7Mol,
A copper agent is sprayed within 5-8 days again away from spraying time interval for the first time.
In the present invention, formulation rate preferably per acre is 6 × 10-6mol。
In the present invention, a copper agent was sprayed again preferably by 7 days.
Embodiment three:
1, test method
Copper agent uses CuCl2·2H2O is diluted with water, concentration needed for configuring.
Test sets 4 processing, 3 repetitions, experimental plot random alignment, plot area 10m2, each cell total strain number is big
In 250 plants, minizone stays protection to go.Copper agent dilution is respectively as follows: A group 1 × 10-6Mol/L, B group 1.0 × 10-7Mol/L, C
Group 1 × 10-8Mol/L, D group are clear water control.Formulation rate per acre is 6 × 10-6mol.The prevention and treatment of other cotton pests and locality are big
Field management is identical.
2, investigation method
Field investigation uses diagonal line five point sampling, 5 points of each cell samplings, and every fixed point investigates 20 plants, seedling stage tune
Look into complete stool cotten aphid quantity.And the insect population of cotten aphid, cotton spider mites is investigated before spray.1d, 3d, 5d investigate cotten aphid number after spray
Amount.Revision insect recluced rate and control efficiency are calculated, every plant of cotton investigates the leaf of upper, middle and lower 3, and cotton spider mites investigation method is the same as cotten aphid one
It causes.
Calculate Revision insect recluced rate and control efficiency according to survey data, formula such as:
Software is analyzed using DPS7.05, the significance of difference between each processing is examined with Duncan formula duncan's new multiple range method.
3, test result
(1) the anti-cotten aphid of copper agent inducing cotton
The investigation for carrying out insect population number after medicament to the cotten aphid of plot experiment is sprayed, field efficacy result ginseng is shown in Table 1, makes
With the copper agent of various concentration the Rectifying efficacies of cotten aphid are had differences after 1d, 3d, 5d, processing A group and processing B group, C group
Preventive effect significant difference；It handles between B group, C group without significant difference, with 1 × 10-7After the concentration of mol/L is applied 5 days, copper agent pair
Cotten aphid Revision insect recluced rate is 15.78%, Rectifying efficacies 32.64%.Comprehensively consider, copper agent inducer prevention and control of aphides is suitable for
Concentration is processing B group, and copper agent concentration is 1 × 10-7mol/L。
Table 1: influence of the copper agent to cotton aphid control effect
(2) the anti-cotton spider mites of copper agent inducing cotton
The anti-cotton spider mites of each plot experiment are carried out with the investigation of insect population number after spraying medicament, and calculates efficiency test result ginseng
See side 2, the Rectifying efficacies of tetranychid are had differences after 1d, 3d, 5d using the copper agent of various concentration, processing A group and processing B
The preventive effect significant difference of group, C group；It handles between B group, C group without significant difference, with 1 × 10-7After the concentration of mol/L is applied 5 days,
Copper agent is 14.68% to tetranychid Revision insect recluced rate, Rectifying efficacies 23.21%.As seen from the experiment, copper agent prevents and treats cotton
