Problems solved by technology

For the prevention and treatment of viral diseases such as rice black-streaked dwarf disease, stripe leaf blight, and corn dwarf disease, there is no effective drug for the treatment of viral diseases at home and abroad. The method of "insect control and disease prevention" is mainly used. The main method is to use chemical pesticides to prevent and control. Its advantage is to kill pests quickly. The disadvantage is that the frequent use of chemical pesticides not only increases the cost of control, pollutes the environment, kills natural enemies, but also causes the resistance of pests, making it difficult to fundamentally control the occurrence of pests.

Embodiment 1

[0012] Sorting 3 large fields with an area of ​​2000 square meters, respectively, planted corn seedlings, and planted bluegrass, bluegrass, and bermudagrass around it.

[0013] Rice seedlings were planted in paddy fields with a contiguous area of ​​2,000 square meters, and bluegrass bluegrass was planted at intervals around them.

[0014] Field surveys revealed that the gray planthopper Laodelpax striutellus The feeding tendency of Falle'a to different host plants is quite different, especially when there are different host plants in the same area, adults of SBPH tend to choose to feed on the plants with strong feeding ability, resulting in different The occurrence of plant pests varies greatly, see Table 1 and Table 2 below for details.

Embodiment 2

[0024] The implementation method for trapping and killing SBPH at the rice seedling stage to control viral diseases is as follows: the experimental area is rice seedling field with an area of ​​more than 300 meters, planting trapping weeds - bluegrass bluegrass around the rice seedling field. Use medicine to kill, no need to use medicine to control rice seedlings. In contrast, the rice seedling fields in the control area were not planted with trapping weeds—Poa annua, and the rice seedling fields were not controlled with pesticides. The survey results showed that the incidence of SBPH in the test area was 82.78%-91.24% lower than that in the control area; the effect of preventing and controlling rice black-streaked dwarf and stripe leaf blight was 63.95%-79.81%, see Table 3 for details.

Embodiment 3

[0029] The implementation method of trapping and killing SBPH at the seedling stage of corn to control viral diseases is as follows: the experimental area is a corn seedbed with an area of ​​more than 100 square meters, planting trapping weeds - bluegrass bluegrass around the corn seedbed, and concentrating after the detection of SBPH pests Use medicine to kill, no need to use medicine to control corn seedlings. In the control area, the trapping plant—Poa crimson bluegrass was not planted around the corn seedbed, and no pesticide was used to control the corn seedling stage. The survey results showed that the incidence of SBPH in the test area was 85.31%~91.69% lower than that in the control area, and the effect of preventing and controlling corn dwarf disease was 66.51%~80.55%. See Table 4 for details.

Abstract

The invention provides a method for killing Laodelphax striatellus by utilizing pest taxis to a plant. The method comprises the following steps: in the seedling stage, through adopting a mode of interval planting in fields and rice seedlings or a mode of planting around the periphery of the rice seedlings, planting white top Poa pratensis so as to induce Laodelphax striatellus to gather on the white top Poa pratensis and realize the centralized killing of Laodelphax striatellus gathering on the white top Poa pratensis. In the overwintering period of white top Poa pratensis in winter and in the over-summering period of white top Poa pratensis in summer, when the total population density of white top Poa pratensis is low, the method can be used for greatly trapping the white top Poa pratensis, thereby reducing the population base number of the white top Poa pratensis in the field; and the method is used for ridges or field borders at the periphery of rice and corn seedbeds, thus a large amount of white top Poa pratensis can be trapped, and the diseases of rice and corn viral and the damage to the rice and corn viral can be prevented and relieved. The method has good total trapping effect, is convenient for operation and saves cost, is an effective method for ecological treatment of rice diseases, and has significance for continuously controlling the generation of rice and corn viral diseases, ensuring the security of food production and product quality and protecting ecological environment.

Description

technical field [0001] The invention relates to a method for preventing and treating gray planthopper by utilizing the tendency of pests to plants. Background technique [0002] SBPH Laodelpax striutellus Falle'a is one of the main pests of rice. It not only feeds on seedlings at the seedling stage of rice, sucks juice from rice ears at the heading stage, but also carries and spreads black-streaked dwarf and stripe leaf blight virus, causing black-streaked dwarf disease of rice and corn. Widespread epidemics of leaf blight and stripe disease have resulted in major losses in rice and maize yields. Therefore, controlling the occurrence of SBPH is of great significance for preventing the occurrence of viral diseases, ensuring safe food production, and increasing farmers' income. For the prevention and treatment of viral diseases such as rice black-streaked dwarf disease, stripe leaf blight, and corn dwarf disease, there is no effective drug for the treatment of viral disease...
