What does PSND mean in DISEASES
Peanut Stem Necrosis Disease (PSND) is a serious fungal disease that affects peanut plants. It is caused by the fungus Sclerotium rolfsii, which attacks the stems of the plants, causing them to rot and collapse. PSND can lead to significant yield losses in peanut crops, making it a major concern for farmers.
PSND meaning in Diseases in Medical
PSND mostly used in an acronym Diseases in Category Medical that means Peanut Stem Necrosis Disease
Shorthand: PSND,
Full Form: Peanut Stem Necrosis Disease
For more information of "Peanut Stem Necrosis Disease", see the section below.
Symptoms
- Stem rot: The most common symptom is the rotting of the stems at the soil line. The stems become soft and mushy, and they may collapse under the weight of the plant.
- Leaf wilt: The leaves of infected plants wilt and turn yellow.
- Stunting: Infected plants may be stunted and produce fewer pods.
- Pod rot: In severe cases, the pods may also rot.
Spread
PSND is spread through the soil. The fungus can survive in the soil for several years, even in the absence of peanut plants. It can be spread by wind, water, or equipment that has come into contact with infected soil.
Management
There are several management strategies for PSND, including:
- Crop rotation: Planting peanuts in rotation with other crops that are not susceptible to PSND can help to reduce the amount of the fungus in the soil.
- Sanitation: Removing infected plants from the field and destroying them can help to prevent the spread of the disease.
- Fungicides: There are several fungicides that can be used to control PSND. However, they should be used according to the manufacturer's instructions.
Essential Questions and Answers on Peanut Stem Necrosis Disease in "MEDICAL»DISEASES"
What is Peanut Stem Necrosis Disease (PSND)?
PSND is a soilborne fungal disease that affects peanut plants, causing severe damage to stems, roots, and pods. It is caused by the fungus Sclerotium rolfsii and can significantly reduce peanut yield and quality.
How is PSND spread?
PSND is primarily spread through infected soil, water, and plant debris. The fungus can survive in the soil for several years and can be transported to new fields through contaminated equipment, seed, or transplants.
What are the symptoms of PSND?
Symptoms of PSND include:
- Stem cankers with brown or black lesions at the soil line
- Wilting and yellowing of leaves
- Reduced plant growth
- Sunken and discolored pods
- White mold on the base of stems, roots, and pods
How can PSND be managed?
Management of PSND involves a combination of cultural practices, chemical controls, and resistant varieties:
- Crop rotation with non-host crops
- Use of disease-free seed and transplants
- Proper field sanitation
- Soil solarization or fumigation
- Application of fungicides
What are the economic impacts of PSND?
PSND can cause significant economic losses in peanut production. Yield reductions of up to 50% are possible in severe infections. Additionally, affected pods may be unmarketable due to discoloration and decay.
Is PSND a threat to human health?
No, PSND is not a threat to human health. The fungus that causes PSND does not produce toxins that are harmful to humans or animals.
Final Words: PSND is a serious disease that can cause significant yield losses in peanut crops. By understanding the symptoms, spread, and management of PSND, farmers can take steps to protect their crops from this disease.
