Milleadh tràth (Alternaria solani)

Pataigin. Lorgar am fungas tràth-mhilleadh anns a’ mhòr-chuid de dh’ùirean far a bheilear a’ fàs buntàta, agus bidh an galar a’ leasachadh gach ràith. Bidh am fungas a’ geamhrachadh san ùir air duilleagan marbha, fìonaichean no tiùban gabhaltach.
Disease development. In the spring, the fungus produces spores on the infected crop residue. Spores are spread to healthy plants by wind and rain. Usually, older leaves close to the ground are infected first. Early blight is more severe as the potato crop ages or if the crop has been stressed by poor nutrition, drought, hail, insect damage or other stress. Plants infected with Verticillium or expressing common mosaic symptoms are particularly
buailteach do thinneas tràth.
Ma tha a’ chiad ghalair dona, faodar lotan a lorg air gasan is tiùbairean cuideachd. Bidh galar tiùbairean a’ tachairt aig àm buain sa mhòr-chuid tro ghearraidhean, bruidhean no lotan. Tha an seòrsa Nordonna buailteach do ghalar tiùbairean.
