Problems solved by technology

[0005] In addition, Steiner's nematode has a good control effect on the teahorn beetle larvae, but there is no report on its application in production
[0006] In the application of non-chemical control of this insect, Bao Qiang et al. reported in 2017 the trapping effect of different color swatches on Sterna sternum in the field, and provided an idea for the control of Sterna sternum with swatches, but in practical application It is found that only relying on the swatches to prevent and control the effect is not good, and the inventors have only about 40% of the color swatches in practical applications.
Non-chemical control swatches have a single effect, and it is difficult to achieve the effect only by swatches

Embodiment 1

[0035] A method for preventing and treating Bronchia tea horn, which innovatively integrates the technology of "pruning + yellow board + beauveria bassiana", including the following steps:

[0036] (1) Surface digging and ditches mixed with fungal medicines: In the winter management of tea gardens at the end of October, combined with deep plowing and fertilization and mixed with fungal medicines, the trenching position is 20-25cm away from the tea pocket, the depth of the fertilization ditch is 20cm, and 40 billion coccidioides are used for the fungal medicines The dosage of Beauveria bassiana is 100 grams per mu. The fertilization is mainly organic fertilizer. Apply 1200 kg of organic fertilizer per mu and 80 kg of compound fertilizer. The mass ratio of nitrogen, phosphorus and potassium in the compound fertilizer is 1:2:3.

[0037] (2) Heavy pruning: the best pruning height should be 30-40 cm from the ground in the first ten days of May after the end of spring tea selection, ...

Embodiment 2

[0040] Embodiment 2 Comparative Examples

[0041] A kind of method of preventing and treating Bacteria chinensis, simple "color plate" prevention and control technology, its implementation steps are compared with implementation 1, and the difference is that in the present embodiment, only step (1) and step (3) are carried out, and step ( 2) and step (4) processing, wherein step (1) does not have Beauveria bassiana by digging and fertilizing the surface.

Embodiment 3

[0042] Embodiment 3 Comparative Examples

[0043] A method for preventing and treating Bacteria chinensis, which combines "pruning+yellow board" control technology, its implementation steps are compared with implementation 1, the difference is that in this embodiment, only step (1), step (2) and step ( 3), do not carry out step (4) processing, and wherein step (1) does not have Beauveria bassiana coccidioides by digging and fertilizing the surface.

Abstract

The invention discloses a non-chemical prevention method for basilepta melanopus lefevre. The method comprises the following steps of (1) performing surface soil turning and trenching and mixed applying of a bacterium agent, (2) performing heavy pruning, (3) hanging yellow sticky boards, and (4) spraying the bacterium agent to adults, wherein in the step (1), deep ploughing, fertilizer applying, and meanwhile, mixed applying of beauveria bassiana are performed during winter management of a tea garden; in the step (2), by the end of spring tea season in early May, heavy pruning is performed ontea trees before eclosion of adults of basilepta melanopus lefevre; in the step (3), before the middle of May, after heavy pruning, the yellow sticky boards are hung before the peak of eclosion of theadults of basilepta melanopus lefevre, and the yellow sticky boards are hung next to the ground in tea bushes; and in the step (4) in late May, beauveria bassiana is sprayed at the peak of eclosion of the adults of basilepta melanopus lefevre; the beauveria bassiana is sprayed to the ground of the tea garden and branches and trunks of the heavily pruned tea trees; and moisture retention and drought resisting management is performed after spraying of the beauveria bassiana. The prevention method obviously improves the effect of preventing the basilepta melanopus lefevre, completely avoids theuse of chemical agents, meets the concept of green environmental protection, is conducive to promoting tea trade, and has relatively high social and economical benefits.

Description

technical field [0001] The invention relates to the technical field of tea tree pest control, and more particularly relates to a method for non-chemical control of the tea horn beetle. Background technique [0002] Tea horn beetle Basilepta melanopus Lefevre is one of the important pests in the tea region of southern my country. Among them, northern Fujian, northern Guangdong, Jiangxi, and Hunan occurred more severely. The insect has one generation per year, overwinters as larvae in the rhizosphere soil of tea trees, and feeds on young or mature leaves of tea trees as adults, leaving only the epidermis on the leaf surface, forming "window spots" with a diameter of 1.5-3.2mm. Sometimes several "window spots" are connected together, resulting in broken leaves, and can induce soft rot, anthracnose and other diseases, thereby affecting the quality and yield of tea. [0003] Existing control of this pest mainly depends on chemical control or artificial control. The traditional ...
