Does the mosaic virus affect corn?
Does the mosaic virus affect corn?
MDMV is the most serious virus of sweet corn. If corn plants are infected with MDMV, ear formation and development are slowed leading to grain yield loss. The damage from MDMV can cause the halting of ear formation and development, ultimately leading to the production of barren ears and direct yield loss.
What is corns virus?
Description: When corn plants fail to grow well and the soil has been adequately fortified with nitrogen, viruses can be the problem. In addition to slow, stunted growth, Maize Chlorotic Dwarf Virus causes new leaves to emerge tannish-yellow, often with red streaks or margins.
How do you control maize disease?
Follow crop rotation. Avoidance of water stress at flowering time reduced disease incidence. Avoid nutrient stress. Apply potash @ 80 kg/ha in endemic areas.
How do you know if a plant has a mosaic virus?
How to Identify Mosaic Viruses and Damage
- The leaves are mottled with yellow, white, and light and dark green spots, which appear to be elevated.
- Plants are often stunted, or they grow poorly.
- Plants may have other deformities and their leaves may be crinkled or wavy.
What are the symptoms of maize disease?
Symptoms
- – Small oval or elongated water-soaked spots which enlarge up to 15 mm long appear on leaves.
- – Lesions develop a tan center and red-brown or orange border.
- – Lesions may coalesce to form large necrotic(dead) patches.
- – Severely infected leaves on susceptible hybrids may wither and die.
Does maize need spraying?
“Maize weed control demands a long window of herbicide application and variable target zone for sprays, from bare soil to heavy weed infestations. But in difficult spring conditions, or soils where slumping can be a risk, seedbeds may be more cloddy than desired.
Are Corns good for health?
Corn is rich in vitamin C, an antioxidant that helps protect your cells from damage and wards off diseases like cancer and heart disease. Yellow corn is a good source of the carotenoids lutein and zeaxanthin, which are good for eye health and help prevent the lens damage that leads to cataracts.
Is Rice a grain?
Any food made from wheat, rice, oats, cornmeal, barley, or another cereal grain is a grain product. Bread, pasta, breakfast cereals, grits, and tortillas are examples of grain products. Foods such as popcorn, rice, and oatmeal are also included in the Grains Group.
What is the maize dwarf mosaic virus?
Maize dwarf mosaic virus. Maize Dwarf Mosaic Virus (MDMV) is a plant pathogenic virus of the family Potyviridae. Depending on the corn plant’s growth stage, the virus can have severe implications to the corn plant’s development which can also result in economic consequences to the producer of the crop.
What are the symptoms of MDMV in corn?
Symptoms. When looking for symptoms of MDMV in corn, one must also be aware of the plant’s growth stage as symptoms may affect the plant differently at various stages. Young leaves, may experience chlorotic spotting which may eventually turn into a mosaic or mottle pattern (“Maize Dwarf Mosaic Virus,” n.d.).
How do you get mosaic virus from plants?
Transmission. Maize Dwarf Mosaic Virus is spread by seed, by infected leaves rubbing on non-infected leaves and perhaps most commonly, via aphids (Lipps & Mills, n.d.). These aphids become carriers after they feed on plants such as Johnson grass, corn or sorghum, or other grass species that are infected with MDMV.
