VDL Fleurs , a chrysanthemum nursery belonging to the Zentoo group , wants to trust less on chemicals and more on effective solutions to moderate disease and blighter . They have bring out how to effectively and sustainably control various pests using a compounding of biological science and immature ( biologic ) crop trade protection agents . Consultant Gerwin Murre at Nufarm convey a walkway around the farm in Naaldwijk ( the Netherlands ) together with farm manager Marco Boekestijn .
Marco Boekestijn get by 3.5 hectares of spray chrysanthemums with a squad of employee . They are grown yr - round , in five cycles a class . Crop protective cover is organized in tightlipped audience with Van Iperen , with an emphasis on growing without chemicals , and this approach path is progressively successful . Marco emphasizes the need to find a balance with three pillar : sustainability , cleanliness , and cost - efficiency . This is best reach through uninterrupted monitoring and intervening when necessary .
Clean through the winter"I am enthusiastic about the use of NeemAzal - T / S combined with predatory bugs and/or parasitical wasps , " Marco explains . " Last wintertime , we carry off to see to it wanderer speck and thripid with this compounding . I follow a agenda of hebdomadary spray with NeemAzal - T / S , always in the morning . With raft of pressure and the gain of an uptake foil , I assure leaf reporting . We see that the predatory touch Phytoseiulus persimilis continues to perform within this concept . The fact that we no longer need to use chemicals with this combination is , of course of instruction , an advantage . " Gerwin from Nufarm adds , " I am proud of with these results and Marco ’s ebullience . It confirms our findings and our end to combine biology with our agent NeemAzal - T / S , as well as other green agents in our bundle . "
job with thrips and aphidsBesides spider mites and , to a lesser extent , leafminers , thrips and aphids ( green peach aphid and black noggin aphid ) are damaging to crop quality . Marco says , " Last saltation , we received cutting comprise thrips . It seemed to be getting out of deal . We acted quickly by scaling up the use of montdorensis predatory mites . Again , we combined this with NeemAzal - T / S with great resolution . Letting nature do its problem is an advantage . It is crucial to stop using NeemAzal - T / S before the flush exchange color . We can still use Batavia in the anthesis phase , which is comparatively mild for predatory mites , but that will terminate next class . This presents raw challenges . We may have to bump off certain varieties ( the regal - colored chrysanthemum ) from our compass . "
Quality does n’t come automaticallyCurrent developments , in which biota act an more and more important role , mean that growers have to be alert to variety in the greenhouse . Marco notes , " Quality does n’t come automatically . I have been active in chrysanthemums almost all my life , and almost every day you’re able to find me in the greenhouse , alert to any plague . " Gerwin conclude , " I see that VDL Fleurs dares to lead the manner while being critical of results . Because , in the end , you want results as a society . "
