A large collection of microorganisms with over 2000 isolates has been established at the Australian Cotton Research Institute for the purpose of identifying potential bio-control agents and developing biological contr

The objective of this study was to examine the distribution of tyre imposed stresses, soil displacements and soil mechanical properties as function of the soil surface geometry.

Supplementary funding was provided by the CRDC allowing three personnel ($1750 each, $5,250 total) from the pesticide chemistry group to attend the 8th International Congress on Pesticide Chemistry, held in Washington

With CRDC permission, the travel award was transferred from Dr Skerritt to Ms A Hill, the diagnostics project leader; there was, however, not a change in itinerary.
