How is Sclerotium Rolfsii treated?

Management systems that can reduce the disease severity include the following:

1. Ensure plant residues have decomposed before planting.
2. Deep ploughing soil to bury host debris and sclerotia is a useful measure.
3. Include non-susceptible crops such as maize and small grains in rotations to reduce inoculum levels in soil.

What is the function of sclerotia?

A sclerotium (/skləˈroʊʃəm/), plural sclerotia (/skləˈroʊʃə/), is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return.

How do you get rid of sclerotia?

Soil solarization will significantly reduce viable sclerotia. It will also help control other soilborne diseases, plant parasitic nematodes, and some weeds. To be effective in control of southern blight, solarization must be repeated every year.

How is Southern blight treated?

Soil solarization is an effective method of killing the fungus in the south, but in northern climates, the soil temperatures may not be high enough to eradicate the disease. Cover the soil with a clear plastic tarp and leave it in place while the heat builds up under it.

Where does the fungus Sclerotium rolfsii live?

Sclerotium rolfsii is found in field and orchard crops, ornamental plants, and even turf. It is primarily a disease of herbaceous plants but, occasionally, as in the case of Ficus, can infect woody stemmed plants. The fungus lives in soil and overwinters in dropped plant debris, such as fallen leaves.

Is there a cure for sclerotium blight on trees?

Southern blight on fig trees produces fungal bodies primarily around the trunk. According to fig sclerotium blight info, there is no cure for the disease, but you can prevent it fairly easily. What is Sclerotium Blight?

What causes sclerotium blight on a fig tree?

Figs with southern blight have the fungus Sclerotium rolfsii. It stems from unsanitary conditions around the root base of the tree. Southern blight on fig trees produces fungal bodies primarily around the trunk. According to fig sclerotium blight info, there is no cure for the disease, but you can prevent it fairly easily.

How long can a sclerotia tree survive in soil?

This may seem drastic, but the tree will die anyway and the presence of the fungus means it can continue to produce sclerotia that will infect other plants nearby. The sclerotia can survive in soil for 3 to 4 years, which means it is unwise to plant any susceptible plants in the site for quite some time.
