Product evaluation takes place during all stages of the R&D process, from early screening through development and registration work, to demonstration trials. In addition to routine efficacy testing, special trials are conducted, such as: crop tolerance/rotation, variety (including GMO/gene-edited) screens, rain-fastness and pest / weed / disease resistance evaluation and monitoring. Application methods used include sprays, granular application and seed treatments, and products are tested for both pre-and post-harvest usage.

The SynTech Research workforce is unrivalled in terms of its industry and agricultural experience. The company provides a design and management service to assist planning of customer’s programs and to provide intelligent protocol inputs.
