One of the pre-requirements for registering an agrochemical is to be able to produce sufficient evidence that it shows the necessary level of activity. The results of field studies are reported and summarized in a Biological Assessment Dossier (BAD) according to EPPO or other regulatory zones. Besides efficacy trials, studies are also done to show the degree of selectivity, or to determine how the product influences the quantity and quality of the harvest.
An additional, increasingly important aspect is estimating the risk of resistance development to all groups of active substances and demonstrating that measures are available to reduce this risk. An assessment is also made of the suitability of an agrochemical for Integrated Pest Management, which involves combining various different techniques to avoid or control damage to crops.
One of the requirements for the registration of genetically-modified plants (GMOs) is to demonstrate in field trials that they are agronomically equivalent to conventional plants.
