Dutch to English Other Agriculture

Hi all

I am translating a marketing text about a fungicide for plants. The section in question includes testimonials from satisfied customers. One of the customers is describing how this product helps combat diseases in chicory. The above term appears in the following sentence:

'In witloof wordt het middel toegepast bij het inschuren van de wortels en bij het overgieten van de kragen in het begin van de forcerie. Hierdoor vrijwaart [product] het gewas van Sclerotinia.'

I think it's another kind of product used to protect plants, as shown on this website: http://www.bol.com/nl/p/luxan-koolkraag/9200000011849227/ but am not sure how it should be translated. I would be grateful for any advice!
