Yellows

yellows

[′yel·ōz] (plant pathology) Any of various fungus diseases of plants characterized by yellowing of the leaves which later turn brown, become brittle, and die; affects cabbage, lettuce, cauliflower, peach, sugarbeet, and other plants.

Yellows

diseases of plants— such as aster, celery, and peach yellows; witches’-broom of delphinium; purple top wilt of potato; and big bud— caused chiefly by mycoplasma-like organisms and by viruses.

Diseased plants are stunted and chlorotic, with many lateral shoots pressed to the main stem. The flowers have elongated sepals, deformed corollas that turn green, and an ovary that germinates into leaflets. Yellows attack many plants (potato, clover, onion, carrot, ornamentals). The reservoirs of the causative agents are weeds such as dandelion and field sow thistle. The disease is transmitted by various species of cicadas after the incubation period of the causative agent in their bodies and also by aphids. Yellows decrease the yields of greens, fruits, and seeds and impair the ornamental qualities of flowering plants. Some yellows (for example, cabbage yellows) are caused by fungi. The symptoms of these yellows are yellowing, wilting of leaves, and premature death of the plant. Control measures include crop rotation, cultivation of resistant varieties, removal of diseased plants, and control of weeds and disease carriers.

yellows

any of a number of plant diseases in which there is significant yellowing of the leaves. Yellows can be caused by a wide range of microorganisms; an example is the virus yellows of sugar beet.

Patient discussion about yellows

Q. My 11 y/o son eyes appear to have a slight yellow in the whites toward the corners. I am assuming he will need blood work, but does anyone have any idea what may be the cause?A. If it's not a spot, but rather a diffuse color, it may be jaundice - high levels in the blood of a substance called bilirubin (http://en.wikipedia.org/wiki/Jaundice).
If your child is generally healthy, and this change appeared without any overt problem (e.g. liver disease or blood problem), or your child had fever or fasted recently, this jaundice may represents Gilbert syndrome. It's a syndrome of slightly elevated levels of bilirubin, and considered not dangerous.

Q. husband has horrible rash bil. below knees to his ankles. it is bright red yellow weeping cracks. On statins He has been on zocor for 15 years and we are so afraid this may have something to do with this drug. He has stopped taking the drug because the pain and weakness, and numbness in his legs is considerable A. i looked up for side effects and i saw only "eczema" as a skin side effect. but it seems odd to me that after 15 years you got this kind of side effect. it should have appeared years ago. you know- it might be a very good idea to go and see a Dr... and not stopping a medication without warning..
