Exosect is granted patents for dust drift reduction and enhanced flowability in sowing seeds

Exosect Ltd, a leading provider of enabling technologies, has been granted a patent in the UK and Canada for improved seed flowability and for improved methods of sowing seeds for dust drift reduction, using its proprietary technology platform, Entostat®.

Entostat is a dry micro-powder, based on natural and/or synthetic waxes and has electrostatic properties. It is used as a delivery platform for a wide range of active ingredients including synthetic chemicals, biopesticides and biostimulants. It significantly improves the delivery of active ingredients via seed treatment application with the benefit of enhanced flowability and reduced dust drift.

This invention brings forward another replacement technology for seed flow lubricants, talc and graphite, which detach easily from the seed creating dust containing insecticide, which some studies have attributed to pollinator decline. In certain markets, such as Canada, talc and graphite are no longer permitted to be used as a seed flow lubricant for corn or soybean seeds treated with neonicotinoid insecticides.

Martin Brown, Exosect’s CEO comments “We have been working on this development for a number of years. This demonstrates yet another significant application for our platform technology, Entostat. Patents covering our technology are filed in all key markets including Canada and we expect them to come to grant imminently. We are in advance discussions with commercial partners”.

Entostat is an electrostatically charged micro-powder. A leading variant of Entostat is based on a carnauba wax blend that is chemically inert.

This variant of Entostat is sustainably harvested from the Brazilian Carnauba palm, Copernica martius (Palmae). Other variants include a range of natural and synthetic waxes and polymers.

Entostat is a non-hygroscopic electrostatic micro-powder that can be produced in a range of sizes and shapes. It can be formulated to microencapsulate synthetic active ingredients offering release retardation and to support biological active ingredients on its surface by electrostatic attraction.

Entostat readily gains an electrostatic charge, consequently it adheres to a range of surfaces including, grains and seeds, insects & animals, building fabrics.

It therefore has the potential to deliver active ingredients at a reduced application rate with equivalent or improved efficacy.
