Ornamental growers in Denmark have been among the first ornamental growers to encompass biologic plant trade protection , with many already induce 10 to 20 twelvemonth of experience . The area is driven by a unripe political orientation , and both the manufacture and the government is driving this gullible passage . Growers are cognizant of the advantages , and continuous research and test are being acquit to better and chance new biologic plant tribute solutions and product . This is explained by Lars Stubsgaard , a life scientist who has been work with biocontrols for 28 years in the Danish company Borregaard BioPlant ApS , which is part of the Biobest group since 2016 and operates in Denmark , Norway , and Sweden . Stubsgaard is the product coach and tests new products and advises agriculturist on biocontrols .
Like ' Økologihaven ApS ' ( in the picture ) , most Scandinavian herb agriculturalist have a ' zero pesticide ' policy . This has been a challenge but instruct us how to control plague and diseases using biocontrol products only , Lars Stubsgaard explains .
Biocontrol in ornamentals - How it all startedAccording to Stubsgaard , biocontrol was , for the first time , taken into ornamentals in the late 80 by Steen Borregaard , the founding father of Borregaard BioPlant . " Before , it was only used for the product of vegetables , where cultivator only had the choice between 4 to 5 biologic beneficial insects . Then , we decided to take it into ornamentals . The Danish ornamental growers were probably the first , even before the Dutch raiser started using it . "
You may wonder why the Danish cosmetic grower need to use it , as it was more expensive and , at that time , less good than pesticides . " As working conditions became more in the spotlight , increasingly more employees did not want to spray with pesticides anymore . So , in lodge to keep these good worker , a shift , or fond duty period , to the manipulation of biocontrol was needed . Then , the growers quickly examine the benefit in their craw as the plants did not acquire resistance to a particular pesticide . So when spraying a pesticide , it will be more effective . "
fond use in ornamental productionNearly all Danish cosmetic growers are now using biologic plant aegis in part of the yield physical process as using it in the whole physical process often would be too expensive explains Stubsgaard . " It is often used in the multiplication orbit . The plants are then tightly spaced , and they often use beneficial insects and biofungicides here . In this way , the crop will record the ruined plants output sphere as a ' clean ' plant without having developed any resistance to any pesticide . "
More ornamental grower to use biocontrolOver the years , many biological plant protective covering products entered the market , and according to Stubsgaard , many more will follow in the future , keeping Biobest officious . " In Denmark , but also in Norway and Sweden , we see that increasingly more pesticides are being banned , thrust ornamental agriculturist to search for alternatives . And on top of that , over the last days , agriculturalist have become heavy and bigger and have been applying for certification like GlobalGAP , which also have strict pattern regarding the utilisation of pesticides . "
According to Stubsgaard , growers that are first now turning toward biocontrol will have to discover to think more prophylactically than what they were used to with pesticides . " They will require to infix beneficials prophylactically , supervise pesterer maturation carefully in the crop and act as accordingly before pests develop in magnanimous numbers . Otherwise , the balance will be cant over , and it will be hard to ward off plant wrong and loss . "
Busy for Borregaard BioPlant ApSBesides fend for ornamental and vegetable raiser , Borregaard BioPlant ApS also suffer most Scandinavian herbaceous plant and cannabis growers , which have increased over the last years . These are very challenging crops when it comes to biologic craw protection . " The popularity and , therefore , production of herbs started around 2005 and has grown significantly . Most of the Scandinavian herbaceous plant cultivator have a ' zero pesticide ' policy , and as there are so many unlike herb motley , unlike crop aegis merchandise and methods are required . And the last couple of long time , we are also busy with supporting medical cannabis cultivator . Denmark was the first country that legitimize the yield of medical cannabis on a large scale . And for the production of this crop , no pesticide at all can be used . The principle are even stricter than for herbs and vegetables ; even soap or oils , like in Canada , are not permit . All these developments teach us how to control gadfly and diseases using biocontrol products only . "
Biobest assortment expandingDue to the developments over the last years and the global trend towards less use of pesticides , Biobest expand and is still boom their potpourri with biological harvest protection product . " Besides the innate choice like good dirt ball , Biopesticides are an crucial part of our tool case in Scandinavia . This could be biofungicides contain spores of good micro-organism , like Trichoderma asperellum in the Modern democratic Cartesian product Asperello ® . Asperello is used against land pathogens like Fusarium ; our experience is that Fusarium will be a challenge for growers in the future now that we have few fungicides useable , Lars Stubsgaard explains . "
At theGreentechin Amsterdam , from June 13 - 15 , Biobest will announce novel digital peter that will help cultivator supervise pest development in glasshouse crops .
