Fusarium wilt
Fusarium oxysporum
What is Fusarium wilt (Fusarium oxysporum)?
Fusarium wilt is a plant disease caused by various forms of the fungus Fusarium oxysporum. It infects a wide range of plants, including carnations, gladiolus, China aster, pea, cyclamen, and others. Symptoms include yellowing, stunting, and death of seedlings, as well as yellowing, wilting, and death of mature plants. In some cases, the symptoms may initially appear on one side of the plant. The disease is characterized by the fungus entering the xylem tissue, plugging it, and producing toxins that cause foliage to turn yellow.
How does Fusarium wilt (Fusarium oxysporum) occur?
Fusarium wilt is primarily reproduced through the production and dissemination of spores. The fungus Fusarium oxysporum produces chlamydospores and conidia. Chlamydospores, with their thick walls, allow the fungus to survive in the soil for extended periods. Conidia, thin-walled spores, are spread through contaminated soil, splashing water, and contaminated tools. When in contact with susceptible plant roots, these spores germinate, penetrate the plants, and establish infection, leading to the occurrence and spread of the disease.
Symptoms
1 - Plant Health
The disease caused by Fusarium oxysporum leads to wilting, yellowing, stunted growth, and ultimately, death of infected plants. This can result in reduced crop yields and economic losses for farmers.
2 - Soil Health
Fusarium oxysporum can persist in the soil, even in the absence of a host plant. As a soilborne pathogen, it can build up over time and cause long-term damage to the soil ecosystem. This can affect the availability of nutrients, soil structure, and overall soil health.
5 - Crop Rotation and Diversity
The presence of Fusarium wilt can limit the choice of susceptible plant species in affected areas. This can disrupt crop rotation patterns and reduce the diversity of cultivated plants, affecting agricultural sustainability and resilience.
Solutions
1 - Resistant Varieties
Use plant varieties that are resistant to Fusarium wilt. Resistant varieties have genetic traits that make them less susceptible to the disease.
2 - Soil Management
Maintain well-drained soil conditions to minimize the risk of infection. Excessively wet or waterlogged soil can create favorable conditions for Fusarium wilt development.
3 - Crop Rotation
Avoid planting susceptible crops in the same area for consecutive seasons. Rotating crops helps break the disease cycle by reducing the buildup of the fungus in the soil.
4 - Sanitation and Hygiene
Practice good plant hygiene by removing and destroying infected plant debris. This reduces the source of inoculum and prevents the spread of the fungus.
5 - Seed Treatment
Treat seeds with fungicides or hot water treatments before planting to reduce the presence of Fusarium oxysporum on the seed surface.
6 - Biological Controls
Some beneficial microorganisms can suppress the growth and activity of Fusarium oxysporum. Consider using biocontrol agents, such as Trichoderma species, which are commercially available.
7 - Fungicide Applications
In severe cases or high-risk situations, fungicides labelled for Fusarium wilt control can be used. Common fungicides include thiophanate-methyl, benomyl, metalaxyl, propiconazole, azoxystrobin, and others. It's important to note that the efficacy and availability of specific fungicides may vary depending on your region, crop, and local regulations.
8 - Soil solarization
Before planting, expose the soil to the sun by covering it with clear plastic. This method helps raise soil temperatures, reducing the survival of Fusarium oxysporum and other soil-borne pathogens.

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.
