Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention is provided. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
Example 1:
the control of the whitefly is realized by adopting the following steps:
the method comprises the following steps: sterilizing the greenhouse: mixing, atomizing and spraying agricultural streptomycin aqueous solution and potassium permanganate aqueous solution; the ratio of 72% agricultural streptomycin to water in the agricultural streptomycin aqueous solution is 1:2000, and the ratio of potassium permanganate to water in the potassium permanganate aqueous solution is 1: 800; streptomycin aqueous solution and potassium permanganate aqueous solution are used for spraying, so that efficient killing of bacteria and viruses in a greenhouse is realized;
step two: placing yellow plates in the greenhouse: placing the yellow plate 20cm above a plant growing point; the yellow plate with sticky surface is hung by utilizing the yellow tendency of the whiteflies, so that the trapping of the whiteflies can be efficiently completed;
step three: spraying 19% aqueous solution of a deltamethrin suspension agent to crops, wherein the ratio of solute to water in the 19% aqueous solution of the deltamethrin suspension agent is 1:1000 to 1:3000, and the 19% aqueous solution of the deltamethrin suspension agent is sprayed to the leaf surfaces and the back of the plants uniformly after atomization;
step four: spraying a pyriproxyfen aqueous solution to crops, wherein the ratio of 100 g/L pyriproxyfen to water is 1:1000 to 1:3000, and the pyriproxyfen aqueous solution is uniformly sprayed to the leaf surfaces and the back of the plants after atomization; the pyriproxyfen aqueous solution has the advantages of good light stability, small dosage, high activity, high leaf conductivity and systemic property, long duration and low toxicity to human bodies and mammals, and is relatively thorough in killing whiteflies by using the pyriproxyfen aqueous solution and less in harm to workers applying the pesticide.
In addition, the method also comprises the following steps: yellow belt walls 3.5-4 m high are made of yellow belts to clean whiteflies, pushed between plants, and blown to the plants by a blower on the other side. The whiteflies are disturbed to fly up and fall on the yellow belt wall; due to the influence of the liquid medicine proportion, the spraying distance and the spraying time, the pesticide is not ideal for killing the whiteflies, so that an additional physical pest killing method is needed to be used for killing the pests.
In addition, the method also comprises the seventh step: arranging an insect-proof net at a ventilation opening of the greenhouse; the specification of the insect-proof net is 50 meshes to 60 meshes. In addition, the method also comprises the following five steps: spraying a washing powder aqueous solution to crops: the ratio of the washing powder to the water is 1:600 to 1: 800. The washing powder solution can dissolve the waxy layer on the body surface of the whitefly and permeate into the whitefly body, so that the parasitism of ova is avoided.
Multiple experiments prove that the body type of the whitefly imagoes is generally not lower than the specification of the 50-mesh insect-proof net, so that the isolation of the greenhouse whitefly invading from the outside is realized by using the 50-60-mesh insect-proof net.
In addition, the method also comprises the following steps: spraying atomized water to the leaf surface and the back of the plant until the chemical agent on the surface of the plant is completely cleaned. The chemical agent is prevented from remaining on the plant, and although the damage of the chemical agent to the plant is inhibited to a greater extent by the dilution and the proportion of the chemical agent, if the plant is not cleaned after the whitefly is cleaned, the growth and the result of the crop are still greatly influenced.
In addition, the method also comprises the ninth step: monitoring diseases and pests: and (3) carrying out sampling investigation on the plants in a subarea manner, checking whether plants with diseases exist or not, recording information obtained through the sampling investigation and the information of the number of the plants with the diseases obtained through the checking, and completing the monitoring of the plant diseases and insect pests.
In addition, in the second step, when the growth height of the plants is stable, a layer of yellow plate is placed on one side of the middle part of the plants, and the place is 15cm-20cm away from the plants on one side of the plants. The whiteflies are further killed and killed, the height of the yellow plates does not need to be adjusted frequently after the growth of the plants is highly stable, and after the plants are mature, the number of leaves is increased, and the yellow plates need to be increased to ensure the trapping rate of the whiteflies.
In addition, the yellow board in the second step is a yellow board with sticky surface; the yellow plate has a gauge of one of 25cm by 30cm, 25cm by 35cm, and 30cm by 40 cm. The yellow boards with the proper specifications are selected according to the growth height of the plants to complete the trapping and killing of the whiteflies, the yellow boards with the specifications are convenient to place and hang in the greenhouse, and the yellow boards with the uniform specifications are used to facilitate storage and management.
In addition, the insect-proof net adopted in the seventh step is a white insect-proof net made of polyethylene raw materials.
In addition, the method also comprises a step ten of releasing the encarsia formosa and/or chrysopidae in the greenhouse when the density of the whitefly adults on the sampled sample plants reaches 0.5 heads per plant. The natural enemies of the whiteflies are protected and utilized to finish the trapping and killing of the whiteflies, and the single method is used for controlling the whiteflies for a long time, so that the drug resistance of the whiteflies can be caused, therefore, the biological natural enemy control method can be used, when the density of the whiteflies reaches a rated value, the encarsia formosa and/or the chrysopa pallidus are released, and the trapping and killing of the whiteflies is finished.
