Severe brown spot infection usually results in smaller seed size. The disease is most severe when soybean is grown continuously in the identical area, particularly in fields where tillage is lowered, since this can be a residue-borne illness. The best approach to handle this is to remove the infected leaves and apply a fungicide.

It becomes less common within the fall and winter as the climate is less conducive to sporulation. The Septoria genus of fungi is type of giant, with over a thousand fungal species. And as can be expected from such a large genus, other forms of this fungal disease exist too. Immediately remove all affected leaves to do away with as many spores as potential.

A copper primarily based fungicide or Biofungicide may be effective at stopping the fungus from spreading though they are greatest used as a preventative.

More than one thousand totally different species of pathogens have been found within the Septoria genus, and every of them infects a unique host. Fungi belonging to the Septoria genus produce pycnidia and ascomycete. These compounds are identified to infect many plant species, including Cucurbitaceae and Solanaceae . Finally, the whole leaf turns into covered by the fungus and ultimately dies.
With these spots, as with tomato or different solanaceous plants, leaves will start to yellow and drop. The solely significant difference is the preliminary shade of the spotting. Usually this process begins close to the bottom with the lowest leaves of a plant. If not treated, the fungi can unfold up larger although the plant.
