Nitricum Acidum

Nitrogenous rich soils and plants. Phosphorus excess. Blotch, black point, mildew, eyespot, purpling of stem and leaves. (3)

Malnutrition, irritation, ulceration, fluid secretion, acts on the skeletal system of the plant and its skin. Cell walls of the vessels that leak easily relaxed to liquid. Septoria spot, stains stagonosphora, helmithosporium sacchari (eye spot) in sac-charrum offinarum, Diplocarpon rosae-fungus (black spot in ro-SAS), mildew generally peronosphora farinosa, microsphaea alni (polvil, white leaves or mildew), chlorosis. (244)

The roots have dark blotches or green (except legumes). They usually have an offensive smell. They are swollen and have an ulcerated appearance. (3)

Swelling in the roots, the roots smell bad. (244)

The stem is either too rigid or too weak, and both are indications of excess nitrogen and phosphorus. (3)

Cracks in the skin and patchy discoloration black, weak stems and bark. (244)

At the 2-4 leaf stage chlorosis may appear. The midriffs turn pink, as well as the petioles. Later the stems turn purple or red. The older leaves turn yellow to orange-red, with red veins. The leaves die and gradually the whole plant becomes affected. As a consequence there is a reduction in branching. Purpling of underside of leaves, pink/red. Yellowing of leaves. (3)

stamen, which either pollinate too early or not at all (3)

Pollination premature or absent. (244)

Fruiting is affected and crop loss may result. (3)

Tree bark cracks, (except on eucalypts where bark sheds as a normal feature). Bark fissures. Fololws Kali carb (3)

Modalities worse with cold or with cold water, by the very hot weather in late afternoon, changes. (244)
