primary symptoms of manganese toxicity in plants

Manganese toxicity is relatively rare, especially in irrigated rice systems and rarely occurs in lowland rice. Toxicity symptoms, induced by low levels of Mn (0.1 ppm and above), included: small brown necrotic spots and veinal necrosis on primary leaves; necrosis on primary leaf petioles; interveinal chlorosis, with or without brown necrotic spots, on trifoliate leaves; and brown necrotic spots on stipules. Neurologic consequences of manganese toxicity have been recognized since 1837 38 when five workers in a manganese ore grinding plant in France developed a variety of symptoms such as low-volume speech, drooling, and loss of facial expression.
