Symptoms
- Yellowish patches or green and yellow mottling on leaves.
- Leaves curl downwards and are distorted and reduced in size.
- Plants are stunted due to a shortening of the internodes (lengths of stem between leaves)
- Reduction in yields and distorted fruit.
- In flowers white streaks known as ‘breaks’ appear.
How do you know if a cucumber is diseased?
There are several common viruses that can affect cucurbits, including Cucumber mosaic virus (CMV) and Watermelon mosaic virus (WMV). Infected plants may be stunted or have leaves that are mottled, crinkled, or a light green color. Fruits may be irregular in shape, mottled, or warty.
How do you detect cucumber mosaic virus?
Cucumber mosaic virus (CMV) is a widespread plant virus infecting important vegetables, plantation and flower crops. Currently, CMV is detected by enzyme-linked immunosorbent assays (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) assays.
How do you treat cucumber virus?
There is no known cure for cucumber mosaic. Infected plants should be removed and destroyed to eliminate the plants as potential reservoirs for the virus (which can subsequently be spread to other nearby healthy plants). Infected plants can be burned (where allowed by local ordinance), deep buried or hot composted.
What does a plant virus look like?
Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope.
Can you eat a cucumber from a diseased plant?
Your cucumber plant may be infected by bacterial, viral, and/or fungal pathogens. Diseased plants may not produce as much fruit (if any), and any fruit that is produced may not be palatable or edible.
Is it safe to eat cucumbers from a diseased plant?
Garden produce from a sick plant is generally safe to eat, although it may not be desirable.
Can you eat cucumbers from a plant with mosaic virus?
“Yes,” says Nebraska Food Safety Educator Carol Larvick, citing information from Minnesota Extension. “These viruses are specific to plants and do not harm humans.
How do you identify a virus?
Virus identification is performed either by indirect immunofluorescence of virus-infected cells using group- and type-specific monoclonal antibodies, or RT-PCR on extracts of cell supernatants using specific primers or probes.
How do I know if my plant has viruses?
Symptoms of virus infection include necrotic spots, abnormal dark green and light green mosaic and mottling of leaves, growth distortion, stunting, ring patterns or bumps on plant foliage, and abnormal flower coloration and formation. Plants may also be infected with more than one virus or viral strain.
What are the most common diseases that affect cucumbers?
» Angular leaf spot, bacterial wilt, Phytophthora crown and root rot, and powdery mildew are important diseases on cucumber. » Time of occurrence, severity, and the yield losses resulting from these diseases vary with geographic region.
What helps get rid of a virus?

- Step 1: Download and install a virus scanner.
- Step 2: Disconnect from internet.
- Step 3: Reboot your computer into safe mode.
- Step 4: Delete any temporary files.
- Step 5: Run a virus scan.
- Step 6: Delete or quarantine the virus.
What does mosaic virus look like?
This virus infects more than 150 types of plants, including many fruits, vegetables, and flowers. It is characterized by leaves mottled with yellow, white, and light and dark green spots or streaks.
Can plants recover from viruses?
Once a plant is infected with a virus, it will never recover. Virus-infected plants should be completely removed and composted. Prevent viral diseases by buying healthy plants and removing weeds from the site before planting.
Can plant viruses be cured?
Plant viruses can only be identified by lab testing. There is no cure for plant viruses, management actions should be focused on preventing virus spread.
Can a virus jump from plant to human?
It is currently accepted that a strict separation exists between plant and vertebrate viruses regarding their host range and pathogenicity, and plant viruses are believed to infect only plants. Accordingly, plant viruses are not considered to present potential pathogenicity to humans and other vertebrates.
What happens if you leave cucumbers on the vine too long?
One of the most common reasons for the color change is simply leaving them on the vine too long. Over-ripened cucumbers will turn yellow and become bitter. If yours are also puffy, large, or have sunken areas or wrinkles, this is likely the problem.
How do you remove poison from cucumbers?
Salt Sprinkling Method
Cut the cucumber into two halves lengthwise. Sprinkle some salt on both the halves from where they were cut open and rub them against each other. You will see the white foamy substance appearing on both the halves. Repeat the procedure two-three times before washing it off with water.
Do cucumbers carry bacteria?
Unfortunately, cucumbers have been associated with several outbreaks of foodborne illnesses in recent years. Cucumbers can become contaminated by bacterial pathogens during production, harvest, post-harvest handling, processing, packaging and distribution.
When should you not eat cucumbers?
