Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. [1] Accordingly, many diseases that primarily exhibit this symptom are called blights. Several notable examples are: [citation needed]
The species are mostly herbaceous perennial plants 0.3–1.5 metres (1–5 feet) tall, but some are annual plants and a few are shrubs up to 3 m (10 ft) tall. An exception is the chamis de monte (Lupinus jaimehintonianus) of Oaxaca in Mexico, which is a tree up to 8 m (26 ft) tall.
Lupinus polyphyllus, the large-leaved lupine, big-leaved lupine, many-leaved lupine, [2] blue-pod lupine, [3] or, primarily in cultivation, garden lupin, is a species of lupine (lupin) native to western North America from southern Alaska and British Columbia [4] and western Wyoming, and south to Utah and California. It commonly grows along ...
Members of genus Prunus have also been theorized to be at fault for mare reproductive loss syndrome. [1] Some plants, including yews, are deadly and extremely fast-acting. [2] Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. [3]
Unless treated, death can be expected to occur within 3–5 days; if they have not died by this time, they often recover. [190] Toxicity varies among animal species: 4 seeds will kill a rabbit, 5 a sheep, 6 an ox or horse, 7 a pig, and 11 a dog. Ducks have shown substantial resistance to the seeds: it takes an average of 80 to kill them.
It has green to gray-green palmate leaves, with 5–12 leaflets per leaf. The leaflets are 2–6 centimetres (0.79–2.36 in) long, often sparsely covered with fine silky hairs. In spring it bears many racemes, 30 cm (12 in) long, of fragrant, soft yellow, pea-like flowers. [1] [2] Both yellow and lilac to purple flowering forms are known ...
Lupinus angustifolius - MHNT. Lupinus angustifolius is a species of lupin known by many common names, including narrowleaf lupin, [1] narrow-leaved lupin [2] and blue lupin.It is native to Eurasia and northern Africa and naturalized in parts of Australia and North America.
The leaves are palmately compound with 7–11 leaflets arranged radially. Their stalks are numerous, erect, striated, and slightly pubescent. The leaflets are obovate, with a blunted apex or pointed spear, and sparsely pubescent. [3] Petioles are longer than leaflets; stipules are very small.
