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.
Can plants recover from virus?
Virus-induced diseases cause severe damages to cultivated plants resulting in crop losses. Interestingly, in some cases, the diseased plants are able to re-gain health, further grow and develop normally.
How long does mosaic virus last in soil?
These investigations have shown that the virus may survive in soils for periods of 1 year or more, but that it is subject to relatively rapid inactivation under certain natural conditions.
Can you eat a watermelon with mosaic virus?
Yes, you can eat squash and melons that are infected with mosaic virus. These viruses are not harmful to humans and do not cause the fruit to rot. Often the discoloration is only skin deep. In cases where fruit are severely distorted, the texture of the fruit may be affected and may not be desirable for eating.
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.
Can you save a diseased plant?
To save a plant from root rot, try removing it from the soil and washing the roots clean. Then, cut the roots back to remove the diseased tissue, and repot the plant in fresh soil after cleaning and disinfecting the container.
What is virus tolerance in plants?
Tolerance has been defined as a mitigation of the impact of virus infection irrespective of the pathogen load (Cooper and Jones, 1983). Although a significant virus load is sustained, the plant growth, yield or reproduction attributes are only minimally affected and visible symptoms are either absent or mild.
How quickly does mosaic virus spread?
Comments on the Disease
Cucumber mosaic virus is spread from plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and local.
How long does it take for mosaic virus to appear?
Symptoms of TMV-infection in susceptible plants:
Symptoms will appear in 1-3 weeks, depending on the variety and concentration of virus in the inoculum. These new leaves on infected tomato plants will exhibit a mottle or green and yellow color pattern and may be distorted. The plants also may be stunted (Figure 11).
Which crop is generally affected by mosaic disease?
mosaic, plant disease caused by various strains of several hundred viruses. A number of economically important crops are susceptible to mosaic infections, including tobacco, cassava, beet, cucumber, and alfalfa.
