Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is to provide a kind of prevention and treatment method of Camellia oleifera sooty disease, to solve the method pesticide currently used for the prevention and treatment of Camellia oleifera sooty disease Problems such as high residual amount and poor control effect, as well as the fact that the natural enemies of pests are killed due to lack of effective protection when chemical control is used, seriously weaken the effect of biological control

Embodiment 1

[0030] The prevention and treatment method of Camellia oleifera sooty disease, comprises the steps:

[0031] (1) pruning the infected branches and leaves of Camellia oleifera in 3-4 months and concentrating treatment to block the source of insects; smearing lime water on the cuts of the pruned branches and leaves as disinfectant for disinfection;

[0032] (2) drop ladybugs on the camellia oleifera tree; the ladybugs thrown in are adults of heterochromia, and the throwing amount of ladybugs is 2 / strain camellia oleifera;

[0033] (3) Spray the imidacloprid medicinal solution to the Camellia oleifera forest in May-June and September-October respectively, drive the ladybugs in the area to be sprayed to the unsprayed area before spraying, and the residual amount of the drug in the area to be sprayed will decrease When it is within the safe value range, drive the ladybugs back to the original spraying area.

[0034] In step (3), the specific way of spraying imidacloprid medicinal ...

Embodiment 2

[0044] The prevention and treatment method of Camellia oleifera sooty disease, main control step is with embodiment 1, and the difference between the two is following 3 points:

[0045] (1) The preparation method of imidacloprid medicinal liquid is: the imidacloprid wettable powder is diluted 3000 times with water, that is, 1g of the imidacloprid wettable powder is mixed with water 3000mL to obtain the imidacloprid medicinal liquid; the content of active ingredients in the imidacloprid wettable powder It is 25wt%; The spraying rate of described imidacloprid liquid medicine is 40L / mu.

[0046] (2) The preparation method of the botanical attractant liquid is as follows: select freshly picked and cleaned wormwood and Vitex, pulverize them to obtain a mixture, put them in a container, add water to the container and seal the container, soak for 6 hours Filtrate, add methyl salicylic acid in the filtrate, promptly obtain the botanical source attractant liquid; the mass ratio of worm...

Abstract

The invention discloses a method for preventing and controlling sooty mould of camellia oleifera, which comprises the following steps: (1) pruning infected branches and leaves of camellia oleifera trees from March to April, and carrying out centralized treatment to block insect sources; and smearing a disinfectant at the pruning openings of the pruned branches and leaves for disinfection treatment; (2) throwing ladybirds on the camellia oleifera trees; and (3) spraying imidacloprid liquid medicine to the camellia oleifera forest in May to June and September to October respectively, driving the ladybirds in to-be-sprayed areas to non-sprayed areas before spraying, and driving the ladybirds back to the original sprayed areas when the chemical residues in the to-be-sprayed areas is reduced to a safety value range. According to the method, biological prevention and control and chemical prevention and control are combined, pests with piercing-sucking mouthparts such as aphids, scabies and whiteflies of the camellia oleifera trees are killed by throwing the ladybirds and spraying the insecticide, and the purpose of preventing and controlling the sooty mould is achieved; and according to the method, the prevention and control rate of the sooty mould of the camellia oleifera can be increased to 99% or above, a large amount of insecticide does not need to be sprayed, natural enemies of the pests cannot be killed when the pests are killed, and high biological safety is achieved.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of Camellia oleifera coal pollution disease. Specifically, it is the prevention and treatment method of camellia oleifera sooty disease. Background technique [0002] The main symptoms of soot pollution are: the affected parts of plant branches, leaves and fruits are covered with black coal dust layers, which will affect the photosynthesis of plants and reduce the yield and economic value of plants. At present, there are many kinds of sooty pathogens known, and different types of plants have different sooty pathogens, and the same plant may also be infected with multiple sooty pathogens. According to the ecological difference of sooty disease, sooty disease can be divided into two types: parasitic and saprophytic. The most typical parasitic sooty diseases are apple soot and pear sooty. The pathogenic bacteria are Deuteromycoides Gloeodes, Gloeodes pomigena (Schw.) Colby, Mycelia...
