What causes bacterial soft rot?
Bacterial soft rots are caused by several types of bacteria, but most commonly by species of gram-negative bacteria, Erwinia, Pectobacterium, and Pseudomonas. It is a destructive disease of fruits, vegetables, and ornamentals found worldwide, and affects genera from nearly all the plant families.
How is Erwinia treated?
There are no compounds that can rid infected plants of Erwinia; although, bactericides containing copper can help slow the spread of the pathogen. Antibiotics have been recommended, but the bacteria adapt and populations become resistant within a matter of weeks.
How is soft rot transmitted?
Soft rot can be spread by infected seed, with infection in the next generation of tubers being higher as the percent infected of seed potatoes increases. Soft rot should be controlled throughout the life of a crop to reduce its impact on future generations of potatoes.
What are the characteristics of bacterial soft rot?
Symptoms of soft rot include soft, wet, rotted, tan or cream-colored tissues. Rot begins on the tuber surface and progresses inward. Infected tissues are sharply delineated from healthy tissue by dark brown or black margins. Shallow necrotic spots on the tubers result from infections through lenticels.
How do you get rid of soft rot in bacteria?
Tips for Controlling Soft Rot Bacteria
- Avoid wet conditions. Make sure plants are in well-draining soil and properly spaced. ...
- Rotate crops with rot-resistant vegetables. Crop rotation goes a long way in managing or preventing problems in the garden. ...
- Use caution during garden maintenance. ...
- Keep the garden and tools clean.
What is soft rot disease?
Soft rot diseases are caused by pathogens that secrete enzymes capable of decomposing cell wall structures, thereby destroying the texture of plant tissue—i.e., the plant tissue becomes macerated (soft and watery). Soft rots commonly occur on fleshy vegetables such as potato, carrot, eggplant, squash, and…
What is Erwinia used for?
Erwinia asparaginase is used to treat acute lymphocytic leukemia (ALL). It works by starving tumor cells of needed nutrients and slowing tumor cell growth.
Can cactus rot spread to other plants?
Soft rot of cactus plants can be spread to other plants by insects, dirty gardening tools and moving of garden debris. It is important to always keep the garden free of possibly diseased garden debris and to thoroughly sanitize your garden tools between each use.
How do you stop soft rot?
Tips to Prevent Soft Rot
- Do not plant infected seed.
- Control weeds esp. nightshades and buffalo bur.
- Avoid harvesting under wet conditions.
- Harvest mature tubers with set skin.
- Harvest when air and soil temperature is below 70oF.
- Harvest when pulp temperature is below 50oF.
- Avoid bruising.
- Dry tubers quickly.
Can you eat a potato with soft rot?
Since bacterial soft rot thrives in water, avoid heavy watering of newly planted potatoes. ... Severely injured potatoes should be eaten immediately as should all immature tubers.
Why do infected potato tubers become soft and mushy?
Tuber soft rot caused by Dickeya and Pectobacterium on infected potato exhibits small, cream to tan, water-soaked surface spots that progress inward. This decay can expand rapidly, resulting in rotting tissue that is mushy, slimy and water soaked (Figure 1).
