Meet Annabelle
I have extensive experience with product development in Northern cropping systems including conventional and transgenic cotton and broadacre summer & winter crops.

Personal & Professional History

After growing up on a cattle property north of Mitchell in south west Queensland where my passion for agriculture and rural lifestyle in general was ignited, I attended boarding school in Toowoomba then completed a six month agricultural exchange in Wyoming, USA on a cattle ranch and near Dusseldorf in Germany working on a mixed dairy and cropping farm. 

On my return I completed a degree at the University of Qld St Lucia campus in 1992 majoring in crop and pasture production. My first position after graduating was as a project biologist with Agrisearch Services, a private contract research organisation, in Narrabri in north west NSW.  A career in product development cotton and broad-acre farming was forged.  My main role was conducting small plot trials primarily developing insecticides, herbicides and plant growth regulators.  I was one of the inaugural graduates of the Grad. Cert Rur. Sc (cotton production) offered through UNE in 1996. 

I then worked as a research and development specialist with what is now Bayer CropScience in Narrabri managing the cotton development program and developing broad-acre herbicides.  I met my husband Bryce in 1994 and he began a contract cotton and broad-acre spraying business, Bryce Guest Spray Services, in 1996 to service row crop and dry-land operations in the Lower Namoi and Gwydir regions.

After having two children, I returned to Agrisearch Services in 2002 and worked initially with statistical analysis of trial data and producing APVMA reports and part 8 efficacy submissions then moved into quality assurance auditing for GLP (good laboratory practise)OECD residue projects.  This involved both in process auditing of the application and sampling of the field phase processes as well as study plan and final report audits.  I also produced the client newsletter on a quarterly basis. 

In 2013, i started AGDel – Annabelle Guest Agricultural Development.  This business provides applied research and development for both field and extension projects on a contract basis.

Areas of specialty are APVMA submissions, technical communications, training in chemical risk management and commercial product evaluation which is conducted in conjunction with Bryce Guest Spray Services. 

Commercial product evaluation focuses on fine tuning spray parameters eg nozzles, water volumes, speed of new products once they are registered or as the last step in product development out of commercial ground rig equipment.
