Potatoes & Field Vegetables

The Potato Portfolio focuses on biorational and conventional products for use not only on potatoes but also on sugar beet, onions, carrots, leeks, brassicas and tobacco.

Crop Focus

The most important crop covered in this Portfolio is potatoes as the Certis product range has a very wide range of products that can be applied in potatoes. Other crops managed within the Potato Portfolio are sugar beet with a more limited number of compounds in the portfolio but also onions, garlic, carrots, leeks, brassicas and tobacco – smaller crops and less prominent market segments but where the Certis product portfolio has some significant and very interesting compounds.

Product stewardship

In order to follow potential changes in late blight sensitivity to fungicides we execute an annual monitoring programme of late blight strains across the main growing areas of potatoes. Our advisory services emphasise that Valbon must be used in line with FRAC guidelines in order to ensure the class of chemistry can be safely used for years to come.

Post-harvest applications of products are critical with respect to application technique and formulation characteristics in order to get a uniform distribution of products throughout the stored crop. Certis continually monitors the way applications of its Gro-Stop products are made. In collaboration with other partners in the value chain, Certis develops innovative new solutions and provides training sessions to support its users in making further improvement in product usage.

Certis is involved in various joint industry and other stakeholder stewardship initiatives.

All Biorational products are officially registered under the crop protection guidelines, which means that the quality and safety of all these products is guaranteed and performance has been proven by scientific research and development trials. We know and can prove what we sell.
