“…These results suggest the carbon–arsenic bond remains intact in turfgrasses with different levels of susceptibility to MSMA. Similarly, researchers have reported that MSMA was not metabolized in cotton, wheat, or common cocklebur (Keeley and Thullen, 1971; Nimbal et al, 1995; Domir et al, 1976). Duble et al (1969) noted that 14 C‐disodium methanearsonate molecule remained largely intact in coastal bermudagrass, suggesting the role of metabolism is not attributed to MSMA injury.…”

“…The researchers found minimal radioactivity translocation from treated leaves with <5% recovered in roots. In wheat ( Triticum aestivum L.), the majority of radioactivity from foliar absorbed 14 C‐MSMA was recovered in treated leaves after 2 wk (Domir et al, 1976). Similar results were noted in broomsedge ( Andropogon virginicus L.), as plants translocated <10% of the absorbed radioactivity from 14 C‐MSMA at 48 HAT (McCullough et al, 2015).…”

Centipedegrass [Eremochloa ophiuroides (Munro) Hack.] and seashore paspalum (Paspalum vaginatum Sw.) can be weedy species with other turfgrasses. Monosodium methylarsenate (MSMA) selectively controls these grasses in polyculture with tolerant species such as bermudagrass [Cynodon dactylon (L.) Pers.], but the mechanisms of selectivity are not well understood. The objectives of this research were to investigate the efficacy and behavior of MSMA in bermudagrass, centipedegrass, and seashore paspalum. In greenhouse experiments, the hierarchical rank of injury ranges for species from high to low was centipedegrass > seashore paspalum > bermudagrass. Monosodium methylarsenate reduced dry shoot biomass of centipedegrass and seashore paspalum six and three times greater than bermudagrass after 4 wk, respectively. The hierarchical rank of lipid peroxidation after MSMA treatments, as measured by malondialdehyde (MDA) content, from high to low was centipedegrass > seashore paspalum > bermudagrass. Grasses reached peak foliar absorption of 14C‐MSMA at 1 d after treatment (DAT), but differences among species were not detected. There was no metabolism of 14C‐MSMA in any species at 1, 3, or 7 DAT, suggesting MSMA could remain bioavailable in clippings of tolerant and susceptible grasses. Overall, the selectivity of MSMA in warm‐season turfgrasses is associated with differential levels of lipid peroxidation.

“…Similarly, application of MSMA at high rates (9 kg/ha) for several years led to increased residues in crops, for example, 2 to 4 ppm of As in corn, cottonseed, soybeans and sorghum (10). In addition, the ability of foliar-applied MSMA to translocate, both acropetally and basipetally, is well established (3,7). Indeed, basipetal movement of MSMA into rhizomes and tubers is a desirable characteristic of this compound for controlling perennial grasses and broadleaf weeds (8,11,13).…”

Arsenic Levels in Crops Irrigated with Water Containing MSMA

1978

Mature plants of tomato(Lycopersicon esculentumMill. ‘Super Sioux’), cucumber(Cucumis sativasL. ‘Early pickling’), and pinto bean(Phaseolus vulgarisL.), in small field plots, were exposed once to sprinkler or furrow irrigation water containing 0.11 kg/ha or 1.12 kg/ha MSMA (monosodium methanearsonate). Concentrations of MSMA in water were about 0.22 ppmw and 2.2 ppmw for the two rates, respectively. Samples of crops and soil were subsequently analyzed for elemental arsenic content by colorimetric and atomic absorption methods. Arsenic residues were higher, compared to controls, only in crops exposed to MSMA applied in sprinkler irrigation. Average arsenic levels were highest in tomatoes exposed to 2.2 ppmw MSMA by sprinkler irrigation, and after 30 and 45 days were 0.26 ppm and 0.35 ppm, respectively. Average arsenic levels in sprinkler-irrigated crops ranged from double to triple the arsenic levels in control (untreated) crops. Atomic absorption was more sensitive than the colorimetric method and could detect smaller differences in arsenic content of samples. The average arsenic residues in soil varied from 1 to 3 ppm, but the differences could not be attributed to treatment with MSMA.

“…Chickpea (Cicer arientium) is the Wfth major important legume in the world on the basis of total grain product. Chickpea has one of the highest nutritional composition of daily edible legumes, on an average chickpea contain 23% of protein, 64% of total carbohydrates, 6% fats and some amounts of minerals such as calcium, magnesium, phosphorus, zinc and iron [3,6]. Chickpea is mainly used for human consumption and small amount for animal feed, and is also used as herbal medicine, cosmetics.…”

The treatment of chickpea milk was carried out in batch, repeated batch and continuous reaction by soluble and polyvinyl alcohol (PVA) immobilized Aspergillus oryzae alpha-galactosidase for the removal of raffinose family oligosaccharides (RFOs). In the batch mode of treatment 96 and 92% of RFOs hydrolysis was observed by soluble and immobilized enzyme, respectively. In repeated batch experiments, immobilized enzyme showed 70% RFOs hydrolysis up to sixth cycle. Polyvinyl alcohol immobilized alpha-galactosidase in fluidized bed reactor showed highest reduction of 94% at a flow rate of 30 ml/h. The results obtained from the present study are very interesting for industrial use of PVA-immobilized enzyme.
