In silico

Protección de cultivos

In silico assessment predicts the potential toxicity of an agrochemical active substance using advanced computation modeling. The reliability and acceptance of in silico techniques is increasing as scientific knowledge and information on active substances grows. Importantly, in silico modeling can provide toxicity predictions rapidly, without animal testing. By working with Covance, you can access expertise in in silico predictions crucial to answering safety questions about your agrochemical and informing the design of in vitro studies.

  • A dedicated team of computational biologists, statisticians, chemists, toxicologists and regulatory experts ensure robust in silico toxicology predictions to support weight-of-evidence arguments for your active substance
  • A comprehensive suite of computational modeling tools employing expert rule-based and statistical-based approaches to maximum effect 
  • In silico predictions are integrated into the wider testing approach for your active substance –optimizing your study spend while still building compelling arguments to regulators

 

Sus necesidades

Without data and with constrained budgets, how do you predict the toxicity of your agrochemical?

Budgets are always constrained and in vitro and in vivo testing can be expensive and takes time. While in silico predictions combined with read-across can build weight-of-evidence arguments for your agrochemical, high levels of experience, skill and insight are needed to use QSARs to build predictions that can withstand regulatory scrutiny.
