How do cucumbers control the mosaic virus?
- Purchase virus-free plants.
- Maintain strict aphid control.
- Remove all weeds since these may harbor both CMV and aphids.
- Immediately set aside plants with the above symptoms and obtain a diagnosis.
- Discard virus infected plants.
- Disinfest tools used for vegetative propagation frequently.
How does cucumber mosaic virus affect plant growth?
Cucumber mosaic virus (CMV) is one of the most common plant viruses, causing yellow mottling, distorted leaves and stunted growth in a wide range of garden plants, not just cucumbers.
Is cucumber mosaic virus harmful?
“These viruses are specific to plants and do not harm humans. The presence of mosaic won’t cause fruits to rot prematurely but severely distorted fruit will have a different texture, so use your own judgement.”
What does mosaic virus do?
THE TOBACCO MOSAIC VIRUS
Tobacco mosaic virus causes a mottled browning of tobacco leaves, and accordingly is of major economic importance. It also infects other crops, most notably tomatoes. The virus is spread mechanically from infected plants to scratched or damaged leaves of normal plants.
What are the symptoms of tobacco mosaic virus?
Symptoms associated with TMV infections:
- mosaic pattern of light and dark green (or yellow and green) on the leaves.
- malformation of leaves or growing points.
- yellow streaking of leaves (especially monocots)
- yellow spotting on leaves.
- distinct yellowing only of veins.
How do you treat a virus in plants?
Unfortunately, there are no chemical controls for plant virus diseases. Dig up and dispose of affected plants – to prevent it from spreading to other plants.
Where does cucumber mosaic virus come from?
CMV is mainly transmitted by aphids, but it can also be mechanically spread by humans in some cases. However, the mechanically spreading of this virus is not as common as the case of other virus (such as Tobacco Mosaic Virus, TMV), because CMV is not a very stable virus.
How is papaya mosaic virus treated?
Affected fruits are small in size and malformed. Control : As soon as the disease symptoms are observed dusting Sulphur (30 g/10 litres of water) or spraying Calixin 75 EC (5 ml/10 litres of water) at 15 days interval helps to control the disease.
Does mosaic virus stay in the soil?
Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.
