Problems solved by technology

[0004] At present, there are many methods and technologies for healthy treatment of watermelon seeds. Chemical treatment is still one of the main measures to prevent seed contamination. However, most of the chemical treatments need to fully clean the seeds. Incomplete cleaning can easily affect the germination rate of seeds and the field. Seedling rate, and many chemicals will cause harm to humans and animals, so it is not suitable for farmers without certain protective facilities

preparation example Construction

[0019] The preparation method of the above-mentioned seed treatment agent is as follows: taking and measuring copper oxychloride, acetic acid, and water according to the above-mentioned proportion, and mixing to obtain the seed treatment agent.

[0020] In a preferred embodiment of the present invention:

[0021] The above-mentioned copper oxychloride comes from king copper wettable powder, preferably 50% king copper wettable powder, wherein the mass percentage of copper oxychloride is 50%; the 50% king copper wettable powder is produced by Jiangxi Heyi Chemical Co., Ltd.; The above-mentioned acetic acid comes from table vinegar, preferably white vinegar, wherein the acetic acid content is 4.0% by volume; the white vinegar is Longmen white vinegar, produced by Beijing Liubiju Food Co., Ltd.

[0022] Above-mentioned seed treatment agent comprises the raw material of following mass-volume-volume ratio:

[0023] 50% king copper wettable powder 2-10, vinegar 5-50, water 500-3000....

Embodiment 1

[0030] The seed treatment agent of the control melon bacterial fruit spot of the present embodiment contains the raw material of following weight ratio:

[0031] 4g of 50% copper king wettable powder (containing 2g of copper oxychloride), 15mL of vinegar (containing 0.6mL of acetic acid), and 1L of water.

[0032] Its preparation method is:

[0033] According to the above proportion, vinegar is added to water to obtain a vinegar dilution; then 50% king copper wettable powder is dissolved in the vinegar dilution and stirred evenly to obtain a seed treatment agent.

Embodiment 2

[0035] The seed treatment agent of the control melon bacterial fruit spot of the present embodiment contains the raw material of following weight ratio:

[0036] 50% king copper wettable powder 2g (containing 1g copper oxychloride), vinegar 15mL (containing acetic acid 0.6mL), water 1L.

[0037] The preparation method of above-mentioned seed treatment agent is:

[0038] According to the above proportion, vinegar is added to water to obtain a vinegar dilution; then 50% king copper wettable powder is dissolved in the vinegar dilution and stirred evenly to obtain a seed treatment agent.

[0039] With reference to the method of operation in the following comparative examples, the seed treatment agent of the present embodiment has an average incidence rate of 1% and a relative control effect of 84.6% in the dry seeds artificially inoculated with Ac bacteria in the control effect of BFB; In terms of the control effect on BFB, the average incidence rate was 2.1%.

Abstract

The invention belongs to the field of crop breeding, and in particular relates to a seed treatment agent for preventing and treating bacterial fruit spot of melons. The treatment agent includes raw materials in the following mass-volume-volume ratio: copper oxychloride 1-5, acetic acid 0.2-2, water 500-3000. The copper oxychloride comes from the wettable powder of copper king, preferably 50% copper king wettable powder; the acetic acid comes from vinegar, preferably white vinegar. The invention adopts copper oxychloride and acetic acid as effective components, and the two act synergistically to increase the sterilization rate, which is suitable for both dry seeds and wet seeds, and can reduce the bacteria-carrying rate of melon seeds.

Description

technical field [0001] The invention belongs to the field of crop breeding, and in particular relates to a seed treatment agent for preventing and treating bacterial fruit spot of melons. Background technique [0002] Bacterial Fruit Blotch (Bacterial Fruit Blotch) of melons is an important disease of cucurbit crops, and it is a worldwide quarantine disease. It was first discovered in Florida, USA by Webb et al. in 1965, and the symptoms were described [1] , the seed carrier is the main source of infection of the disease [2] . [0003] In recent years, with the rapid development of intensive seedling-raising factories, the scale of industrial grafting and seedling cultivation of melon has become larger and larger. Due to the high density of industrial seedling cultivation and the high temperature and humidity in the seedling cultivation environment, bacterial fruit spot The long-term diffusion and large-scale occurrence provide favorable conditions, resulting in heavy loss...
