Bean plants

Methyl parathion may also be introduced into the air as a result of its volatilization from plant surfaces, and somewhat from soil, especially in the period just after application. Under simulated field conditions (20° C air velocity 1 meter/second relative air humidity 40-60%), an emulsifiable concentrate formulation of methyl parathion was applied to bare soil and bean plants. After 24 hours, the amounts of methyl parathion that had volatilized from bare soil and bean plants were 5 and 64% of the applied amount, respectively (Rudel 1997).

Delayed-action cytotoxins that inhibits protein synthesis (ribosomal inactivating protein). They are obtained from the seed of the Jequirity beans plant (Abrus precatorius). Typically yellowish-white powders that are insoluble in distilled water but soluble in salt water. They are fairly heat stable. 

CDC Case Definition A clinically compatible case with (1) detection of urinary ricinine, an alkaloid in the castor bean plant or (2) detection of ricin in environmental samples. The case can be confirmed if laboratory testing is not performed because either a predominant amount of clinical and nonspecific laboratory evidence is present or an absolute certainty of the etiology of the agent is known.

Protein quality studies evaluating various edible portions of the winged bean plant and the results of recent International Field Trials are reviewed. Research efforts have been focused upon the mature seed (protein content 20.7-45.9% in 240 accessions), which is occasionally eaten in parts of Indonesia and Papua, New Guinea. Autoclaved seed meal and wet heat treated seed meal provided a corrected PER value of 1.76 and 1.72 respectively, in comparison to casein control of 2.50.

Plot 4 The onions, garlic, and fava beans planted the year before (see Plot 1). Grow salads over winter. Add leaf mold in spring. 

What to do Earlier sowings of fava beans are less susceptible to attack. Pinch out tips of fava bean plants in May or early June, or when pests are seen. Remove heavily infested plants. See also Aphids.

Yonkers et al, have tested the ozone susceptibility of 15 species of annuals common to the Mojave Desert just north and east of the Los Angeles basin (and San Bernardino Mountains). Compared with the susceptible pinto bean plants included in the experiment with ozone at 0.35 ppm, Plantago sp., Cercidium sp., and Prosopsis sp. were also sensitive. Further interpretation of these results is complicated by the influences of plant age and pre-exposure conditions. 

Plant. In plants, mevinphos is hydrolyzed to phosphoric acid dimethyl ester, phosphoric acid, and other less toxic compounds (Hartley and Kidd, 1987). In one day, the compound is almost completely degraded in plants (Cremlyn, 1991). Casida et al. (1956) proposed two degradative pathways of mevinphos in bean plants and cabbage. In the first degradative pathway, cleavage of the vinyl phosphate bond affords methylacetoacetate and acetoacetic acid, which may be precursors to the formation of the end products dimethyl phosphoric acid, methanol, acetone, and carbon dioxide. In the other degradative pathway, direct hydrolysis of the carboxylic ester would yield vinyl phosphates as intermediates. The half-life of mevinphos in bean plants was 0.5 d (Casida et ah, 1956). In alfalfa, the half-life was 17 h (Huddelston and Gyrisco, 1961). 

Parathion degraded on both glass surfaces and on bean plant leaves. Metabolites reported were paraoxon, 4-nitrophenol, and a compound tentatively identified as 5-ethyl parathion (El-Refai and Hopkins, 1966). Upon exposure to high intensity UV light, parathion was altered to the following photoproducts paraoxon, 0,5-diethyl 0-4-nitrophenyl phosphorothioate, 0,0-diethyl 5-4-nitrophenyl phosphorothioate, 0,0-bis(4-nitrophenyl) 0-ethyl phosphorothioate, 0,0-bis(4-nitrophenyl) 0-ethyl phosphate, 0,0-diethyl 0-phenyl phosphorothioate, and 0,0-diethyl 0-phenyl phosphate (Joiner et al., 1971).
