Monosodium methyl arsenate (MSMA) is an arsenic-based herbicide.It is an organo-arsenate; less toxic than the inorganic form of arsenates. It is one of the most common and cost effective herbicides used against weeds in agriculture.MSMA products are unique in that they combine selectivity, low weed-resistance, and cost-efficiency.MSMA is an herbicide used to control a wide spectrum of hard to control grass and broad-leaf weeds including some weeds that are resistant to the herbicide Glyphosate.t is an organo-arsenate; less toxic than the inorganic form of arsenates.

Methylsulfonylmethane (MSM) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including DMSO2, methyl sulfone, and dimethyl sulfone. This colorless solid features the sulfonyl functional group and is considered relatively inert chemically.SM and the corresponding sulfoxide dimethyl sulfoxide ((CH 3) 2 SO, DMSO) have different physical properties. MSM is a white crystalline solid at STP (m.p.
