Technical Field

The invention relates to a botanical plant protection preparation for preventing and treating tea plant insect pests and a preparation method thereof.

Background

The tea root rot is a disease with high risk in a tea garden, and pathogenic fungi infect tender tissues of the root of a tea tree to cause the root to rot, so that plants die. The disease has a long process from disease infection to plant death, the nutritional deficiency is easy to confuse in the early stage of disease attack and is not easy to identify, once found, the root damage is serious, and irreparable economic loss is caused.

The tea root rot can be developed in the whole growth period, wherein the full-blown period is 6-9 months. The tea root rot is divided into tea purple vein feather disease, tea white vein feather disease, tea red vein feather disease, tea brown vein feather disease, tea black vein root rot disease and the like, wherein the tea purple vein feather disease and the tea white vein feather disease are in a full-term of attack in 6-7, and the tea red vein feather disease, the tea brown root rot disease and the tea black vein root rot disease are in a full-term of attack in 8-9 months.

Tea root rot easily occurs in plots with moist soil, over-high acidity and poor drainage.

Cinnamomum camphora (with the academic name of Camphorum longipaniticulatum (Gamble) N. Chao ex H.W.Li) is evergreen arbor of Lauraceae, with height of 20 m and diameter at breast height of 50 cm; the bark is gray, the branch is cylindrical, hairless, the young branch is fine, the leaves are intergrowth, oval or elliptical, the tip is suddenly short and gradually sharp to long and gradually sharp, the upper surface is dark green, bright, the lower surface is grey green, dark, the two surfaces are hairless, the leaf stalk is flat and back convex, light green, the cone inflorescence axillary, is fine, the branch is fine and weak, each branch is 3-7 flowers of the polypodium, the shaft is hairless, the flower is light yellow, fragrance is provided, the stalk is fine, the flower quilt is cone-shaped, the flower quilt is oval, the filament is white and soft, the filament is glandless, the anther is long round, the ovary is oval, the young fruit is spherical, the flower is in 5-6 months, and the fruit is yielded in 7-9 months.

Yibin is the primary resource of the cinnamomum camphora, and by the end of 2018, 47 ten thousand mu of cinnamomum camphora forest base in the whole market has the crude cinnamomum camphora oil yield of over 70 percent of the whole country, the yibin crude cinnamomum camphora has high oil yield and good oil quality, and belongs to a non-inspection product in the international market.

At present, the main methods for extracting the crude camphor oil include a CO2 supercritical extraction method, a water vapor steam extraction method, an extraction method and the like, and target products are extracted from the crude camphor oil through the extraction methods, wherein safrole is one of the target products.

The existing safrole is generally used as a spice or used for synthesizing the ocean Lial, and other purposes are not reported.

Detailed Description

The present invention will be further explained below.

The examples provided herein are merely to further illustrate the invention and should not be construed as limiting the invention in any way.

It will be apparent to those skilled in the art that the materials and methods of operation used in the present invention are well known in the art, unless otherwise specified, in the following.

In the present invention, parts by weight means measured in units of weight, such as 1 part by weight means: when the weight is Kg, 1 part by weight means 1 Kg; when the weight is g, 1 part by weight means 1g, and the like, and is not limited to a specific Kg or g.

In the following examples 1-3, mancozeb, calcium lignosulfonate, anionic wetting agent, silica, kaolin, and safrole were all commercially available, wherein the safrole was prepared by extracting crude camphor oil.

Example 1

1.5 parts of Sendzein and 1 part of safrole by weight are replaced, and the components are uniformly mixed.

② adding 0.5 weight part of calcium lignosulfonate, 0.3 weight part of anion wetting agent, 0.5 weight part of silicon dioxide and 0.9 weight part of kaolin into the mixture of the first step, and uniformly mixing for later use.

Example 2

Firstly, 2 parts by weight of seng manganese zinc and 1 part by weight of safrole are replaced, and the components are uniformly mixed.

② adding 0.5 weight part of calcium lignosulfonate, 0.3 weight part of anion wetting agent, 0.5 weight part of silicon dioxide and 0.9 weight part of kaolin into the safrole of the first step, and uniformly mixing for later use.

Example 6

The samples prepared in each of example 2, example 4 and example 5 were subjected to a tea root rot resistance test.

The test was divided into example 2 group, example 4 group, example 5 group and control group.

And (3) selecting plots of areas with moist soil, over-high acidity and poor drainage to plant test tea tree seedlings, and planting the seedlings in spring with the specific date of 3 months and 01 days.

The planting test is divided into 12 small plots with equal area, and each plot has an area of 15 meters by 15 meters. Wherein, the embodiment 2 group corresponds to three small plots, the embodiment 4 group corresponds to three small plots, and the embodiment 5 group corresponds to three small plots; the corresponding group corresponds to three small plots.

The application rate of the plots of example 2 was 1.95 kg/acre as active ingredient, the application rate of the plots of example 4 was 1.95 kg/acre as active ingredient, and the application rate of the plots of example 5 was 1.95 kg/acre as active ingredient. The control group was blank and no tea root rot resistant agent was administered.

The planting distance of the tea trees is 150-166 cm, and the planting distance is 45-50 cm.

The field management such as fertilization before and after planting is the same respectively.

After planting, the tea root rot condition is observed by taking the leaves as the main part and the roots as the auxiliary part. The observation period is 3 months 02 days to 9 months 30 days after planting, the observation frequency is once in 7 days, and the control effect in the two periods is respectively counted after the last observation at the bottom of 7 months (first statistics) and after the observation at the bottom of 9 months (second statistics), wherein the first statistics is that the diseased plant in the period of 3 to 7 months is counted, and the second statistics is that the diseased plant in the period of 8 to 9 months is counted.

Table 1 below is a table of the tea root rot resistance of the samples of example 2, example 4 and example 5 with a blank control.

TABLE 1 tea root rot prevention Table for samples of example 2, example 4 and example 5 with blank control

In table 1, the control effect calculation formula is: control efficacy is 100 × (mean number of diseased plants per group-mean number of diseased plants per control group)/mean number of diseased plants per control group.

Wherein the average number of the diseased plants in the control group is the sum of the number of the diseased plants in the control group/3, and the average number of the diseased plants in each group is the sum of the number of the diseased plants in each group/3.

As can be seen from table 1, there is a synergistic interaction between mancozeb and safrole in the prevention and treatment of tea root rot.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
