Insect pests impose massive costs in food production, in human health and in the wellbeing of our companion animals. Chemical insecticides remain a major weapon in the control of these pests, but the use of insecticides has some downsides. The way in which insecticides kill insects is poorly understood and insecticide usage has negative impacts in the environment – the persistence of chemical residues and the killing of beneficial insects along with the pests. Further, insects become resistant to insecticides, so pest control is lost. This proposed research seeks to identify the ‘achilles heal’ in insect pests and to target them with new generation insecticides to gain safe, effective and sustainable control.Read moreRead less
Porous Mineral Formulations for Controlled-Release Applications. The controlled release of biologically active agents from host materials is a process that is used routinely in pharmaceuticals delivery but has received only limited attention in large-scale, low-cost areas such as the agrochemicals industry.

These little-studied minerals, for which high quality deposits exist in Aus ....Porous Mineral Formulations for Controlled-Release Applications. The controlled release of biologically active agents from host materials is a process that is used routinely in pharmaceuticals delivery but has received only limited attention in large-scale, low-cost areas such as the agrochemicals industry. Here we identify a number of rare tubular mineral phases as having great potential for low-cost controlled release. These little-studied minerals, for which high quality deposits exist in Australia, consist of hollow tubules of nanoscale dimension. This project involves the first ever studies of the kinetics of guest release from these fascinating hosts, and promises to generate important new technologies in agrochemical delivery.Read moreRead less
