Embodiment 1

[0018] Embodiment 1: A kind of blueberry diseased branch cuts and smears the ointment, taking the production of 100L product as example:

[0019] 1) Measure 37.5L of Vaseline and 37.2L of lanolin and melt in a water bath at 40°C;

[0020] 2) Measure 2L of pyraclostrobin suspension concentrate with a mass fraction of 30%, 10L of chitosan aqueous solution with a mass fraction of 0.5%, and 13L of liquid paraffin, and add them to the molten liquid of vaseline and lanolin and stir for 30 minutes;

[0021] 3) Add 0.3 L portion of fatty alcohol polyoxyethylene ether, and continue stirring for 10 minutes;

[0022] 4) Adjust the pH value of the solution to 6-6.5, keep the viscous colloid, and fill it into a bottle.

Embodiment 2

[0023] Embodiment 2: pyraclostrobin toxicity test

[0024] In order to understand the exact toxicity of different fungicides to blueberry branch blight, the present invention screens effective agents for preventing and controlling blueberry branch blight.

[0025] Three kinds of pathogenic bacteria causing blueberry branch blight, Botryosphaeria dothidea, Phomopsis vaccinii and Pestalotiopsis clavispora (isolated from dead branches in blueberry orchards in Qingdao, Shandong), were collected from natural For the diseased plants, the diseased branches were isolated by the conventional tissue separation method. After the isolated strains were purified and cultured, their pathogenicity was verified by Koch's law, and then the single cells were purified and stored on a PDA slope, and stored in a refrigerator at 4°C for later use.

[0026] Test agents: Ⅰ (250g / L pyraclostrobin should be pyraclostrobin emulsifiable concentrate), Ⅱ (24% carbazole suspension), Ⅲ (25g / L fludioxonil susp...

Embodiment 3

[0034] Example 3: Field efficacy test of different fungicides on blueberry grape stalk blight

[0035] Test agents: Ⅰ (250g / L azoxystrobin suspension 1500 times liquid + 0.5% chitosan water 300 times liquid); Ⅱ (25g / L fludioxonil suspension seed coating 3000 times liquid + 0.5% chitin Polysaccharide water 300 times liquid); Ⅲ (250g / L pyraclostrobin EC 1800 times liquid + 0.5% chitosan water 300 times liquid); Chitosan water solution 300 times) and CK (water control).

[0036] Method: The experiment was carried out in the blueberry plots with disease in previous years in Qingdao blueberry base. The experiment was repeated 3 times (plots), and the plots were randomly arranged. There were 3 trees in each plot, a total of 15 plots, and a total of 45 trees. Immediately after the fruit picking, the first spraying was carried out, and the second spraying was carried out at an interval of 10 days.

[0037] Before spraying, each tree had 40 branches in 4 directions from east to west,...

Abstract

The invention discloses an ointment applied to pruning wounds of diseased branches of blueberry plants. The ointment is prepared from the following components: 0.5-3.0 parts of a pyraclostrobin suspending agent with mass fraction of 30%, 5-15 parts of chitosan aqueous agent with mass fraction of 0.5%, 10-20 parts of liquid paraffin, 0.2-0.5 part of fatty alcohol-polyoxyethylene ether, 25-45 parts of Vaseline and 25-45 parts of wool fat. The application also discloses a preparation method and application of the ointment. The ointment is mainly used for promoting healing of pruning wounds, caused by pruning diseased brancheswith shoot blight, of blueberry plants and preventing newly born branches under the pruning wounds from being infected by shoot blight again.

Description

technical field [0001] The invention relates to an ointment for scissors, in particular to an ointment for scissors with blueberry diseased branches. Background technique [0002] With the expansion of blueberry planting area and the increase of years, the problem of disease has become increasingly prominent, especially blueberry deadwood disease has devastating damage to susceptible plants. It often causes the susceptible branches to wilt and die, and the flowers and fruits to dry up and fall off, which can lead to the death of dozens to hundreds of trees. The main pathogens causing blueberry branch blight are Botryosphaeria dothidea, Pestalotiopsis clavispora and Phomopsis vaccinii. Among them, the branch blight caused by Botryosphaeria dothidea is the most common in the field. [0003] According to laboratory toxicology tests, pyraclostrobin is the drug that has a strong antibacterial effect on the above three pathogenic bacteria. Pyraclostrobin, molecular formula: C ...
