Entostat delivers microbial control agents

Entostat delivers microbial control agents directly to the target organism. This may be the body of an insect or a plants’ rhizosphere.

Using microbials to control insect and plant pathogens is becoming increasingly important in the Agriculture, Public Health and Animal Health sectors to combat insect resistance, reduce environmental impact and meet tightening regulations.

The effectiveness of microbial control agents is well documented, few products have been successfully commercialised due to a number of key technological challenges, including fermentation, formulation and delivery systems.

Beauveria bassiana (Bb)

Exosect has developed the use of Entostat to efficiently deliver the entomopathogenic fungi, Beauveria bassiana, to crawling insects which infest and spoil stored grain and other commodities.

The dry Entostat formulation delivers Bb to the fabric of the grain silo and in admixture where target insects pick up the Entostat particles and Bb spores via electrostatic attraction.

Further application methods are in development.

The grain industry is currently relying on limited pesticides due to regulatory withdrawals. This will be the first biological formulation developed for stored grain with future extension in to other commodity storage sectors.

  • This technology is due to be submitted for EU registration in 2014
  • It is currently being evaluated by the Queensland University of Technology with the Grains Research and Development Corporation
  • It is being evaluated for small holder farmers in Sub Saharan Africa with Bill & Melinda Gates Foundation

Entostat delivers the mycorrhizal fungi, (Trichoderma) to a plants’ rhizosphere as a seed treatment. In crop protection, trichoderma is commonly supplied as a wettable powder and applied to the soil as a drench which has economic and technical drawbacks.

Entostat delivers trichoderma as a dry formulation via a seed treatment. Entostat adheres strongly to the seed coating, significantly reducing dust drift compared to other dry carriers and also reduces clumping. This delivers sufficient conidia directly to the soil surrounding the seed.

This formulation has the potential for enabling the application of the seed treatment at various stages of the supply chain.
