Is an example of the seed-borne disease?

Seedling blight (Fusarium SP. Source of infection: Infected seed, soil and crop debris. Symptoms: Loss of plants, poor establishment, stem based browning, foot rots and ear blights.

What are seed diseases?

Seed diseases are caused by fungi which may be on the seed at planting or by fungi in the soil. They are often responsible for poor emergence and thin stands. Seedling diseases occur after germination until shortly after emergence.

How are seed-borne diseases?

Seed-borne diseases are diseases of plants that are transmitted by seed. In some cases the seed transmission is insignificant as compared to the population density of the pathogen that exists in soil or on weed species. In other instances, the disease spreads primarily through seed.

How do you control seed-borne disease?

Fungicides have been used routinely to control seedborne pathogens and are often the cheapest and most effective means for control. Fungicides are used to kill or to inhibit growth of seedborne fungi and can be systemic or nonsystemic in their action.

Which of the following is a seed borne disease?

Solution : Bacterial blight of rice is a seed borne disease which is transmitted to paddy. Seedlings when raised under high humid conditions. This disease is caused by Xanthomonas oryzae.

What is meant by seed borne?

seedborne (not comparable) (of a plant disease, bacteria or virus) Transmitted with seeds.

What does seed borne mean?

What are seed borne fungi?

Seed- borne diseases are pathogens such as bacteria, fungus, or viruses, which live on the surface or interior of seed and have the potential to spread disease to the subsequent crop.

Can seeds carry disease?

Seed-borne diseases are pathogens such as bacteria, fungus, or viruses that can live on the surface or interior of the seed and have the potential to spread the disease to the next season’s crop. Seed-borne disease infection varies widely by crop, disease, and location.

Which of the following is made to prevent seed borne diseases?

Phenylmercuric acetate is most commonly used as a fungicide. It is also used as a seed dressing for the prevention of seed-borne diseases of vegetables, soybeans, cotton, peanuts, beets, and ornamental plants.

Is Alternaria seed-borne?

Alternaria brassicicola is a necrotrophic fungus causing black spot disease and is an economically important seed-borne pathogen of cultivated brassicas. Seed transmission is a crucial component of its parasitic cycle as it promotes long-term survival and dispersal.

What are disease resistant seeds?

Resistant Varieties may be: Completely/fully resistant – plants do not develop any noticeable symptoms of disease. In some cases, the pathogen may still infect the disease resistant variety and reproduce in the plant without causing disease (i.e. Vertillium and Fusarium wilt resistant tomatoes).

Do you know about the seed-borne diseases of pulses?

The chapter includes major pulses and their seed-borne diseases. Damages caused by the seed-borne diseases are considerably high in some pulses; hence it is need of hour to care about the seed health. Seed is the richest source to be attracted by pests and diseases resulting into several seed-borne diseases.

What are the diseases of pulses?

Among the diseases of pulses, seed-borne/seed-transmitted diseases play a crucial role in the reduction of achievable crop yields. The major seed-borne diseases of pulses are Ascochyta blight, Botrytis (grey) mould, Stemphylium blight, anthracnose, Alternaria leaf spots, bacterial blight, mosaic, etc.

What is the quality of pulse seed?

If the seed is for planting, “quality” refers to seed that has a high germination, is intact, free from foreign materials and weed seeds and has zero or low levels of seed-borne diseases. This article will focus on the importance of seed-borne diseases in quality pulse seed.

What is seed-borne/seed-transmitted disease?

Seed is the first source of inoculum of pathogens and its transmission. ‘Pathogen-free’ or ‘disease-free’ or ‘zero-tolerance’ concept becomes practically an unrealistic and impossible goal under these conditions. Among the diseases of pulses, seed-borne/seed-transmitted diseases play a crucial role in the reduction of achievable crop yields.
