Problems solved by technology

Its disadvantage is that the pests must land on the sticky insect board to be stuck. For pests with weak flying ability or weak tendency, the control effect is not ideal, and the pests without flying ability cannot be controlled. In addition, it should not stick to the leaves of plants, so as not to cause damage
Chinese patents CN2116354U and CN2560207Y have announced a patented technology combining glue and light, which further improves the control effect, but still cannot control pests that cannot fly
International patent WO2003EP00706, U.S. patent US20020047348, Japanese patent JP20020188718, and JP10233920 disclose a variety of trap devices that use the stickiness of glue to catch pests. These devices are relatively large and can only be placed in places where pests are infested, and cannot prevent pests from actively attacking plants. attack
[0004] CN1911012A discloses a kind of glue composed of rosin, castor oil and paraffin that can be applied on the trunk to prevent scale insects on the trunk and to use as a sex trap, but this glue belongs to oily glue. Do not touch plant leaves and young tissues, so as not to cause injury
At present, most of the prevention and control of diseases and insect pests by humans is still in the stage of passive defense, and there is no active defense method for diseases and insect pests. Therefore, it is necessary to use the principle of bionics to improve the defense ability of plants against diseases and insect pests, so as to achieve the purpose of environmental protection and pollution-free

Embodiment 1

[0031] Embodiment 1: After the tomatoes are planted in the greenhouse, when the seedling height grows to 30-40 centimeters, select the sunny morning or evening to start spraying. The spray method is as follows: take 2.5 liters of viscous glue, filter through a 150-mesh filter, put it in a cleaned sprayer medicine box, add 2.5 liters of pure water, stir evenly and set aside. If the control object has obvious phototaxis, the viscous glue can be diluted with pure water at a ratio of 1:1 first, and the fluorescent powder can be added after stirring evenly. For example, yellow fluorescent powder can be added to control whitefly, and blue fluorescent powder can be added to control thrips. Phosphor powder, stir evenly again, filter, and put it in the nebulizer medicine box for use. If the greenhouse vegetables have diseases at the same time, a certain amount of compatible fungicide can be added to the sticky glue. The type of fungicide can be selected according to the type of disease...

Embodiment 2

[0032] Example 2: In the early stage of vegetative growth of field crops or before the occurrence of pests, choose a sunny and windless morning or evening to spray. The spray method is: take 4 liters of viscous glue, filter through a 150-mesh filter, and put it in a cleaned sprayer medicine box for use. If pests occur at the same time as diseases, you can add an appropriate amount of fungicide according to the type of disease and the type of fungicide you choose, stir evenly and filter through 150 mesh for use. Adjust the electrostatic voltage of the sprayer to 40,000 volts, the sprayer fog particles are 80-90 microns, and spray 2-3 meters away from the crop canopy, and the crop straw should be sprayed evenly up and down. In the whole growing season, usually only one spraying can effectively prevent and control small and medium-sized pests and common diseases, and spray again if the diseases and insect pests are serious. The bionic glue used is an environmentally friendly mat...

Embodiment 3

[0033] Embodiment 3: Before the flowering of the field apples after the leaves are fully unfolded, choose a sunny and windless morning or evening to start spraying. The spray method is: take 5 liters of viscous glue, filter through a 150-mesh filter, and put it in a cleaned sprayer medicine box for use. For example, the main purpose of control is to prevent and control pests that already have synthetic pheromones, such as peach borer and golden moth. At this time, a certain amount can be added according to the instructions according to the type of pheromone, stirred evenly, filtered, and placed in a sprayer. box for use. If the fruit tree has diseases at the same time, and the spraying time is before the disease infestation occurs, a small amount of compatible fungicide can be added to the viscous glue according to the type of disease, and the 150-mesh filter can be used in a sprayer medicine box for use. Adjust the electrostatic voltage of the sprayer to 90,000 volts, the sp...

Abstract

The present invention provides a method for controlling plant diseases and pests by utilizing biomimetics principle. It is characterized by that a glue with viscosity can be sprayed on the plant surface, so that the harmful living beings can be adhered on the glue so as to attain the goal of controlling plant diseases and pests. The described atomizer is a kind of electrostatic sprayer optimally, and in the described glue with viscosity the various additive components of trace insect sexual pheromone and fluorescent matter also can be added so as to further raise the effect for controlling plant diseases and pests.

Description

technical field [0001] The invention belongs to the technical field of disease and insect pest control, and in particular relates to a method for controlling plant disease and insect pests by using the principle of bionics. technical background [0002] All kinds of harmful organisms in agricultural production, such as various pests and pathogenic microorganisms, are one of the main obstacles to high-yield and high-efficiency agricultural production. For this reason, human beings have made unremitting efforts. Methods, in the use of toxic natural substances of plants, animals, minerals, has accumulated a lot of experience and handed down, and thus invented various pesticides such as various insecticides, fungicides, acaricides, etc., agricultural production once jumped to the top up a new level. The invention of pesticides has solved the problem of food and clothing for human beings to a certain extent, and is one of the great inventions of the 20th century. However, the w...
