Rice koji disease is a fungal rice disease caused by Sclerotinia oryzae, also known as rice blast, and its pathogen is a fungus of the genus Rice blast, which can survive in the soil for many years and is transmitted through seeds and soil. The occurrence and development of the disease is affected by a variety of factors, including climate, soil, rice varieties, cultivation measures, etc., this disease will lead to different degrees of disease spots and death in the leaves, stems and ears of rice plants, mainly occurring in the late stage of rice growth, especially in the rice maturity period, the disease has a great impact on rice yield and quality, and has brought great losses to agricultural production.
First of all, rice koji disease will lead to a decrease in rice yield, after the occurrence of the disease, rice leaves will appear brown spots and dryness, the growth of the plant is inhibited, resulting in a decrease in the number and weight of grains, in addition, the disease will also lead to a decline in rice quality, such as rice hardening, brittleness, color blackening, etc., so that the quality of rice does not meet the national standards, thereby affecting market sales.
Secondly, rice koji disease will affect the rice planting environment, after the occurrence of the disease will make the air humidity in the field increase, which is more conducive to the spread and infection of pathogens, so that the spread of the disease will expand, at the same time, the disease will also lead to the increase of weeds in the field, increasing the difficulty and cost of weeding.
Finally, rice koji disease will also pose a potential threat to human health, if the rice infected with rice koji fungus is accidentally eaten, it may cause vomiting, diarrhea and other symptoms, causing harm to human health.
In conclusion, rice koji disease is a common rice disease, which will lead to the reduction of rice yield and quality, and also has potential threats to the rice planting environment and human health. Therefore, it is of great significance to strengthen the prevention and control of rice koji disease, improve farmers' awareness of prevention and control, and adopt scientific prevention and control methods to ensure rice production and people's health
Choose disease-resistant varieties and breed healthy seedlings.
Strengthen field management, keep the field dry and ventilated, and avoid water accumulation in the field.
Adopt reasonable fertilization methods and avoid over-fertilization.
Chemical pesticides are used for disease control, but attention should be paid to the amount and method of use of pesticides to avoid impacts on the environment and human health.
Measures such as crop rotation and fallow should be adopted to reduce the incidence of diseases.
Electrolyzed water can also be used as one of the methods to prevent rice koji disease, and the following are the steps to use electrolyzed water to prevent rice koji disease::
Prepare electrolyzed water: A certain amount of water is injected into the electrolyzed water generator, and then energized for electrolysis, and the amount and concentration of electrolyzed water can be adjusted as needed.
Spraying electrolyzed water: At different stages of rice growth, electrolyzed water can be used for spraying, generally speaking, spraying at the rice heading stage and grain filling stage, with a dosage of 500-1000 liters per mu.
Pay attention to the spraying method: when using electrolyzed water spraying, you should pay attention to the spraying method and skills: it should be sprayed evenly to avoid missing spraying or overspraying.
Pay attention to the spraying time: When spraying with electrolyzed water, you should avoid hot and windy weather conditions, and it is best to choose the morning or evening when the temperature is low.
It should be noted that the effect of electrolyzed water in preventing rice koji disease may vary depending on the region and climatic conditions, and the use of electrolyzed water for prevention and control should be adjusted and optimized in combination with the actual local situation, and at the same time, attention should also be paid to protecting the environment and personal safety, so as to avoid adverse effects on the surrounding ecological environment and human health.
