US9307758B2 - Polyacrylamide based agricultural
A polyacrylamide based agricultural composition as a microemulsion is provided in form of a water-in-oil microemulsion with polyacrylamide dissolved in the water phase where the polyacrylamide solids content is from about two up to about 15 percent by weight, which is then further diluted in water at the time of use to impart the desired characteristics of the polymer to the water phase or to the material to which the water phase is applied.

Polyacrylamide in Agriculture and Environmental Land
The word polyacrylamide and the acronym “PAM” are generic chemistry terms, referring to a broad class of compounds.There are hundreds of specific PAM formulations. They vary in polymer chain length and number and kinds of functional group substitutions as well as molecular conformation, the most important conformation variation being linear or cross‐linked conformation.

Information on acrylamide and dangerous chemicals in foods
Exposure to acrylamide from other sources is likely to be significantly less than that from food or smoking, although scientists do not yet have a complete understanding of all the sources. There are some industrial and agricultural uses of acrylamide and polyacrylamide. However, regulations are in place to limit exposure in those settings.

Advanced Turbulent Drag Reducing and Flocculating
Synthetic Polyacrylamide based polymers and polysaccharides such as guar gum, xanthan gum carboxymethylcellulose and starch have been used for long. The Polyacrylamides are easily amenable to shear degradation although they are very efficient drag reducing and flocculating agents even at low ppm concentrations.

Using Surfactants, Wetting Agents, and Adjuvants
Many pesticides require the addition of an adjuvant, and some do not. When applying fungicides, insecticides or herbicides without a recommended adjuvant, 30 percent to 50 percent reduction in pest control can be expected. Adjuvants may cause damage to a plant if the wrong adjuvant is used or if it is used at too high a concentration. Using the correct adjuvant on a greenhouse crop is a
