Celery diseased

Oils may contain toxic compounds. For example, Myristicin is the compound that flavors nutmeg and mace it is also found in black pepper and carrot, parsley, and celery seeds. Used in culinary quantities, myristicin is only a flavoring. In massive doses, it causes hallucination. Thujone, the anise-flavored oil in wormwood, caused an epidemic of brain disease in drinkers addicted to the now-banned liquor absinthe. Sassafras contains a toxic oil similar to thujone, which is why it is no longer used to make root beer. Very high doses of menthol, from peppermint, may cause dangerous irregularities in the heart s rhythm (Weiss, 1997)... [Pg.632]

The triorganotin species have been used as industrial biocides for over 30 years [117, 118]. Examples are triphenyltin hydroxide (structure 5) for fungal diseases on celery, rice, sugar beets, and coffee tricyclohexylstannyl-1,2,4-triazole (structure 6) as an acaricide for apple, pear, and citrus fruit trees bistributyltin oxide (structure 7) as a wood preservative and tributyltin-methylacrylate monomers (structure 8) polymerized with other acrylates to yield a marine antifoulant polymer that prevents the build of up barnacles, algae, and other marine animals on ships. [Pg.330]

Leaves yellow and mottled stalks twisted plant dwarfed. Cause Celery mosaic. Destroy infected plants. Control aphids because they can spread viral diseases as they feed. Prevent problems by planting resistant cultivars such as Florida 683 and Utah-52-70R Improved . [Pg.63]

Extreme cases were first reported in celery strains bred specifically for their resistance to fungus (pink-rot disease). The compounds produced trigger fatal phototoxicity in pest species, as well as severe photodermatitis in field workers [41]. It has also been well documented that celery plants stressed by fungal invasion produce elevated levels of these compounds (3 to 30 times higher than normal) [42]. Cases of photodermatitis triggered in humans by ingestion of celery (e.g., [36]) and other plants [43] are also occasionally reported. [Pg.225]

Mancozeb is a fungicide used to control many fungal diseases such as blight, leaf spot, rust, downy mildew, and scab in field crops, fruits, nuts, vegetables, ornamentals, etc. In particular, it is used to control the following early and late blights of potatoes and tomatoes leaf spot diseases on celery, cucurbits, beets. [Pg.368]

Linear Furanocoumarins in Diseased Celery. There are a number of reports of linear furanocoumarins (12,13) in diseased celery, and the effects of diseased celery (10,30,31) on celery... [Pg.298]

Unfortunately, there are no quantitative data on the amounts of psoralens in diseased celery. [Pg.298]

The actual role of linear furanocoumarins in the disease resistance of celery is unknown however, it has been concluded that the phytoalexins studied to date play an important role in resistance (47). [Pg.307]

Types of dark-brown or black granular muck have produced large quantities of vegetable crops and are often used for grain production and stock farming. Fertilizers, especially potash, can be used profitably. Rotations with oats and rye are common when the principal crops, such as onions, celery, and cabbage are threatened with insects and plant diseases. The production of reed and sedge peat and muck for soil improvement is of commercial importance in this area. [Pg.599]

The most Important use of body odors in disease diagnosis relates to the infant diseases involving errors in amino acid metabolism. Strong and unusual odors are manifest in the breath, sweat, and urine of these individuals. Table II summarizes several known acidurias, the amino acids that are not properly metabolized, and the odors associated with the compounds which accumulate and can be detected in the urine ( ). In the case of the Maple Syrup Urine and Oasthouse syndrome, the keto- and hydroxy- acids which have been identified may not be responsible for the observed maple and celery/yeast odors (.9). Alternatively, these odors could be the result of conversion of 2-keto-butyrlc acid to methyl-ethyl-tetronlc acid (Slusser s lactone) which is used as an extender in maple and celery flavors and has a maple syrup-like odor (R. Soukup, personal communication). With these acidurias it is imperative that an immediate diagnosis is made, since corrective diet can prevent the brain damage that results from these diseases. This is readily done on an olfactory basis which can subsequently be supported by gas chromatographic... [Pg.196]
