Pesticide formulations based on Pickering emulsions

Solid particles often stabilise emulsions better than surfactants, which results in a longer storage time. Since the turn of the millennium, interest in these, often sustainable, stabilisers has increased significantly. Adjuvants & Formulations explored research and development trends in agrochemistry and beyond.

Rhizosphere microorganisms affect root uptake

Rhizosphere microorganisms increase the root uptake of insecticides in maize seedlings. However, their effects on the plant’s growth and translocation depend on the nature of these microorganisms. Adjuvants & Formulations summarizes briefly the results of this Chinese study.

More news in this issue:

  • Emulsification mechanism of surfactants in different oil phases
  • Effect of glufosinate rate and addition of ammonium sulphate on annual weed control in glyphosate/glufosinate/2,4-D-resistant soybean
  • Potential of bio-sourced amphiphilic xanthan as an emulsifier in O/W dispersions
  • Review about mitigating the effects of poor water quality on herbicide performance
  • An oral dsRNA delivery system based on chitosan for the control of Apolygus lucorum
  • Ester-based surfactants: Are they stable enough?

 

Patents in brief

UPL has applied for a patent on seed treatment products that derive the correct viscosity and particle size from a lignosulphonate salt and an acrylic copolymer and/or a polyalkylene glycol ether.

Adjuvants & Formulations also reports about activities of other companies as well as universities, such as:

  • Granulation aid for low-melting pyrethroid and moisture sensitive actives
  • Carboxylic acid herbicides, chelating agents and cationic surfactants
  • Overview of recent patent publications with brief summary
