Orange rust
Arthuriomyces peckianus
What is Orange Rust (Arthuriomyces peckianus) and (Gymnoconia nitens)?
Orange rust is a fungal disease that affects blackberries and black raspberries. It is caused by two different fungi: Arthuriomyces peckianus on black raspberries and Gymnoconia nitens on blackberries. The disease is found in various regions, including the Northeastern United States. Symptoms include stunted and deformed leaves, yellowing, orange growths on the undersides of leaves, and later, black spots on leaves. Infected plants may have weak shoots, fewer blossoms, and fruit. While orange rust weakens plants, it typically doesn't kill them.
How does Orange Rust (Arthuriomyces peckianus) and (Gymnoconia nitens) occur?
Orange rust occurs through the reproduction of the fungal pathogens A. peckianus and G. nitens. The disease spreads through spores produced by the fungi. These spores are released from the orange growths (aecia) on the undersides of infected leaves. The spores can be carried by wind, water, or contact with contaminated materials, allowing them to infect healthy plants. Once the spores land on susceptible host plants, they germinate and establish infection, leading to the development of new orange rust lesions. This cycle continues as infected plants produce more spores, perpetuating the disease's spread.
Symptoms
1 - Impact on Plants
• Orange rust primarily affects the health and productivity of blackberries and black raspberries. Infected plants may exhibit stunted growth, deformities, reduced blossoms, and weak shoots. The disease weakens the plants, leading to decreased fruit production. • However, orange rust itself is not known to directly harm soil or have significant environmental impacts.
Solutions
1 - Cultural Practices
1. Source Planting Material Carefully: Purchase from reputable sources, avoiding infected plants. 2. Choose an Ideal Planting Location: Select a sunny spot away from woodlots or riverbanks. 3. Early Spring Scouting and Removal: Scout for infected plants and dig them out, including the roots. 4. Prevent Spore Spread: Remove and destroy infected plants before spores are released. 5. Maintain Air Circulation: Prune old canes, thin healthy canes, and keep the area weed-free.
3 - Chemical Control
• Chemical control options for orange rust in blackberries and black raspberries include Abound, Quadris, QuiltXcel, Rally 40 WSP, and Spectracide Immunox Multi-Purpose Fungicide Spray Concentrate for Gardens. These fungicides can prevent new infections but won't cure existing ones. • Follow label instructions, avoid silicone-based surfactants, and consider pre-harvest intervals and reentry periods. • Spot treatment with herbicides can be used to kill infected plants. Consult local regulations, and always read and follow the product labels for proper and safe use.

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.
