Big vein
Lettuce big vein virus
What is Big vein (Lettuce big vein virus)?
Big vein disease is a soilborne viral disease transmitted by the oomycete (Olpidium virulentus). Symptoms include enlarged leaf veins with clear areas, puckered and mottled leaves, and failure of head formation. The disease is prevalent in wet, cool conditions They have been detected in lettuce, garland chrysanthemum, tomato, eggplant (MLBVV), onion, Welsh onion, and Chinese chive.
How does the Big vein (Lettuce big vein virus) occurs?
Big vein disease occurs through the transmission and reproduction of viruses by the soilborne oomycete, Olpidium virulentus. The oomycete attaches itself to lettuce roots, introducing the viruses. The viruses can survive in the soil for several years within resting sporangia. When uninfected oomycete strains encounter infected plants, they acquire viruses, continuing the cycle of transmission. The disease can also spread through weedy hosts acting as reservoirs for the oomycete and viruses.
Symptoms
1 - Effects on Plants
The disease can cause stunted growth, resulting in reduced yield potential. Big vein disease can affect the overall quality and marketability of lettuce and related crops.
3 - Effects on the Environment
Big vein disease affects various plant species, potentially impacting crop diversity and ecosystem dynamics.
Solutions
1 - Avoid Early Planting in Wet Soil and Long Rotations
• Refrain from planting lettuce and other susceptible plants, early in wet soil or poorly draining fields with a history of the disease. • Wet and cool conditions promote disease spread. • Implement long crop rotations on heavily infested land. • Avoid planting lettuce or susceptible crops in the same field for an extended period.
2 - Residue Management and Disease-Free Land
• Remove and dispose of crop residue instead of incorporating it into the soil. • Prevents pathogen buildup and persistence. • Choose land not previously planted with lettuce, if possible.
3 - Soil Steam Treatment
• In seedbeds or greenhouse settings, steam treatment of the soil can be effective in reducing the population of the vector (Olpidium virulentus) and the associated viruses. • This can help create a healthier planting environment and reduces disease incidence.

FAQ
Do shade growing plants need any Sunlight?
Shade growing plants do need sunlight, although they require less than other plants. They need some direct sunlight each morning to help them photosynthesize and grow properly. Also, indirect sunlight throughout the day helps them stay healthy. Shade growing plants will benefit from the sunshine, but if they get too much or too little, then they can suffer the consequences. It's important to pay attention to the needs of your plants so that you can provide them with the proper light for optimal growth.
How often should you water indoor plants?
Indoor plants should be watered when the soil feels dry to a depth of about two inches, usually about once a week. A helpful technique to determine your plants' watering needs is to feel the soil before and after watering to get a sense of how long it takes to dry out. An important note to remember is that some plants require less water than others, and it's best to research the specific needs of your individual plants. Likewise, if your home is very dry, you might need to water more often as the lack of moisture can stress the plants and lead to problems like brown leaves and wilted stems.
Can my monstera plant get root rot?
Yes, a plant can get root rot. Root rot is a fungal disease that can be caused by over-watering, poor soil drainage, or high humidity levels in the air. Signs of root rot include yellowing leaves, wilting and stunted growth, and damaged or browning root systems. Sometimes it is difficult to detect root rot until the plant is removed from the soil, as the problems are mainly below the soil surface. Treating root rot usually involves removing the affected parts of the plant and replanting the unaffected ones.
Can I put my Monstera outside in summer?
No, you should not put your Monstera outside in summer. Monstera plants need warm, humid air to thrive, and direct sunlight can scorch their leaves. Instead, put your Monstera in a bright, sunny spot with indirect light, making sure the sun never directly hits the leaves. During the summer, keep your Monstera's soil damp and mist it occasionally to keep the leaves hydrated. At nighttime, keep the temperature around 16 - 21°C (60 - 70°F). You can definitely take your Monstera outdoors for short periods of time, just make sure to bring it back in if it starts to get too hot.
What happens if my monstera plant gets too cold?
If your monstera plant gets too cold, it will become vulnerable to pests, disease, or other damage. Cold temperatures can damage the leaves of the plant, causing them to become spotted or limp. The roots of monstera plants may also suffer in cold temperatures, leading to root rot or other diseases. Belonging to the tropical family, monsteras are used to warm environments and do not do well in cold temperatures, so it is important to ensure your plant is kept in conditions that suit their needs.
Is it possible to grow a vegetable garden in a small space?
Yes, it is possible to grow a vegetable garden in a small space. Gardening in a small space can be as simple as growing a few containerized plants in pots and raised beds, or as elaborate as vertically stacking planters, hanging pouches, and hanging baskets on a wall, railing, or fence. Regardless of the size of the space you are working with, some simple techniques such as companion planting, organic fertilizers, and water conservation can help you get the most out of your small vegetable garden.
Is peppermint herb green good for digestion?
Peppermint herb is indeed beneficial for digestion. The flavonoids in the herb support digestion by reducing inflammation in the digestive track, aiding in digestion and relieving indigestion, heartburn, and even the symptoms of irritable bowel syndrome. Additionally, peppermint is naturally rich in menthol, which helps to relax the muscles of the stomach, aiding in the digestion of food. Peppermint herb can be consumed in a variety of forms, such as teas, tinctures and capsules, as well as by adding the herb to food or directly to water or tea.
Should peppermint herb green be consumed daily?
No, peppermint herb green should not be consumed daily. This is because it contains high levels of menthol, which can be toxic if taken in large doses. Additionally, consuming large amounts of peppermint herb green could interfere with the absorption of essential minerals and vitamins, potentially causing vitamin deficiencies. For these reasons, it is best to consult with a doctor before incorporating peppermint herb green into your daily diet.
