Seeds can also carry bacteria to cause disease. Pathogenic bacteria mainly penetrate through the epidermis directly or invade from pores and wounds to cause diseases, and conidia generated on diseased plants are spread in the field by airflow, rainwater sputtering and farming operation. The growth and development temperature of pathogenic bacteria is 2-35 ℃, the suitable temperature is 20-22 ℃, conidia are easily generated at the relative humidity of more than 93% and the daily average temperature of 15-30 ℃, the conidia can germinate at the temperature of 5-30 ℃ when the relative humidity of 100% is the most, and the suitable temperature is 15-25 ℃ and requires water drops and nutrition. When the minimum field temperature is above 10 ℃, the relative humidity is higher than 90% for a long time, and the condensation of the leaf surfaces of plants occurs seriously.

from the above table, it can be seen that in example 2, the raw material proportion is moderate, the processing temperature is moderate, and the processing technology is most suitable for preparing the bactericide for preventing and controlling the cladosporium cucumerinum of the xi honey pomelo, the bactericide prepared in this example has the best curative effect, the disease resistance of the xi honey pomelo is obviously improved, the recovery ratio of good fruits of the xi honey pomelo is improved, the bactericide is effective in sterilization and antibiosis, and has no drug resistance, the production cost is reduced, and the income of fruit growers is greatly improved at the same time, in the technical scheme, one of the mixture of lime sulfur, boldo liquid, nitrile bacteria manganese zinc and zineb is adopted as an antibacterial pesticide, the alkaline pesticide is matched with potassium carbonate to adjust the pH value, so that the Cladosporium cucumerinum fungus is inactivated without damaging probiotics and tree tissues, the environment is protected, trace elements of the honey pomelo are further increased, the nutrition is improved, and the chlorophyllin is added as a water soluble fertilizer to be sprayed on, promoting absorption of fruit trees, enhancing the immunity of the fruit trees, having antibacterial effect of chitosan and polydopamine, meanwhile, can be used as a carrier to adsorb and culture pectinase and SOD enzyme, is matched with a plant activator benzothiadiazole, the fruit tree preservative has certain control effect on fruit tree germs, can enhance the resistance of honey pomelo trees, improve the fruit quality, has good fruit surface coloring and storage resistance, can induce the synthesis of lignin in honey pomelo peels, improve the system resistance of the honey pomelo, reduce the damage of fungi of deuteromycete cucurbita scabbing branch sporotrichia to fruits, and the technical scheme also adds a surfactant and a film-spreading oil agent to be matched with an emulsifier for stirring, so that the film-spreading oil agent can be fully mixed in a bactericide and is added with water for spraying when in use, the film-spreading oil agent is retained on the surface of the pomelo fruit and locks a part of antibacterial factors, so that the pomelo fruit has a long-term antibacterial effect, and the germination probability of fungi imperfecti cucurbita scab mycoderma can be greatly reduced under the condition that the pomelo fruit is kept in a dry state.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of the invention, which is defined by the appended claims, and any modifications, equivalents, improvements and the like, which come within the spirit and scope of the invention are intended to be embraced therein.
