Sean Weith

Field Agronomist

With a Bsc in plant science, a master’s in plant protection and being in the process of completing a PhD on white clover and nitrogen fixation, Sean adds considerable value to Bayer’s portfolio of crop protection products.

Before joining the company full-time in 2020, Sean worked for seven years as a trial assistant for Bayer.

His focus is the Canterbury region where he runs trials in barley, wheat, onions, grapes and potatoes – mainly looking at new insecticide and herbicide formulations.

A key aspect of his role is collecting quality data and entering it into a central database where it can be analysed and used to make informed decisions about potential new product formulations.

The aim is to develop new products under local conditions that benefit farmers.

Sean believes the two biggest threats to farmers is resistance to fungicides and herbicides, as well as the seasonal uncertainties caused by climate change.

To combat these issues, he believes transparency and good communication between growers, merchants, seed and agrichemical companies is essential.
