Red spot disease is a major threat to faba bean crops, causing significant leaf loss and leading to blackened and dried stems. This condition reduces the crusting rate and increases the open space rate, which severely impacts both the yield and quality of the crop. This year, the unusually high temperatures during winter and spring, combined with continuous rainfall after spring, have created ideal conditions for the spread of red spot disease. The disease has appeared earlier than usual and is spreading rapidly.
According to systematic observations conducted on March 7 and 12, the infected plant rate reached 100%, with intercropped fields showing 96.67% and 100% infection rates respectively. The disease index was recorded at 19.33 and 24, while in pure fields, the disease rate also hit 100% with an index of 21.33 and 22. On March 10, 10 different types of faba bean fields were surveyed, and the red spot disease incidence was found to be 100% across all sites. The rate of infected leaves ranged from 89.66% to 100%, averaging 98.02%. This is the highest level of occurrence recorded since 1975.
Considering various environmental and agricultural factors, it is expected that this year’s red spot disease will occur at a moderate level. However, if the flowering period coincides with rainy weather, the disease could become more severe, especially in vulnerable areas.
To manage red spot disease effectively, farmers should focus on improving field drainage by clearing ditches, reducing soil moisture, and enhancing the plant's natural resistance. Infected branches should be promptly removed and properly disposed of to minimize the spread of pathogens. For chemical control, it is important to apply treatments at the right time—starting from the early flowering stage. A recommended application is 70g of 25% prochloraz wettable powder or 80g of 50% triazole wettable powder per mu, mixed with 50-60 kg of water for full coverage. Spraying should be done every 7-10 days, with 2-3 applications recommended for optimal results. Proactive measures are essential to prevent widespread damage and ensure a healthy harvest.
Vitamins
Vitamins are essential organic compounds that bodies need in small amounts to function properly. They play a crucial role in maintaining good health and preventing various diseases. There are 13 essential vitamins that are classified into two categories: water-soluble and fat-soluble.
Water-soluble vitamins include vitamin C and all the B vitamins (thiamin, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, vitamin B12, and folate). These vitamins are not stored in the body and need to be replenished through diet or supplements daily.
Fat-soluble vitamins include vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver and can accumulate to toxic levels if taken in excess. Therefore, it is essential to consume these vitamins in moderation.
Each vitamin has a specific role in the body, and a deficiency in any of them can lead to various health problems. For example, vitamin C is essential for the immune system, wound healing, and collagen synthesis. Vitamin D is necessary for bone health and calcium absorption, while vitamin A is crucial for vision and skin health.
Of course animals need vitamins too, for example vitamins K3,medicine vitamins,Menadione,poultry vitamins,feed vitamins to boost immunity and growth.
