This project aims to inform distribution / extension pathways for a new pest management technology, based on a form of silica known as synthetic amorphous silica (SAS), to small landholders in Tanzania.

The proposed research activity will focus on understanding the range of insect pests for which SAS can demonstrate a level of control. In addition, this data will be collated as a first step towards product registration.

ACIAR has supported an initial assessment of the technology (CIM-2015-009) in which SAS was applied by hand to insect pests in laboratory / enclosed field shed settings in Timor Leste and Tanzania.

Expected outcomes

  • Determining the target range of storage insect pests for which SAS may provide control.
  • Exploring and demonstrating how the principles, present in the current SAS prototype application machines developed by Davren Global, may be re-engineered to be relevant in Tanzania.
  • Undertaking a community consultation process through small landholder focus groups to inform both the development and in-country testing an application device for small landholders and exploring issues around distribution / service delivery models for the new technology.
  • Bringing together the new knowledge and learnings in the form of a draft business plan to inform future distribution, support and financing of the technology.
