In some case , customer at home and abroad have to act upon with products from Anthura for as many as 30 hebdomad before they go to the end grocery . It is therefore extremely important that the merchandise they receive is sizable and clean . Aphid control is becoming more hard , and Anthura is currently devoting additional attention to how it can be managed .
Marjolein van der Knaap and Peter Vogel . Anthura have a wide-cut ambit of amount in place to maximise the character and the wellness of the plants awaiting delivery .
" We ’re seeing how much backbreaking we need to sour with the biology – we want to accelerate progress , " explains Peter Vogel . Peter is the polish manager at breeder Anthura , based in Bleiswijk , the Netherlands , and works with two polish specialists , sharing responsibility for the plant at the troupe ’s anthurium output site . Things need to move quicker , and not only because the governance is more and more remove pesticides from the market and the fact that use of those products that are available is subject to ever more stringent confinement . Rather , it ’s the non - statutory bill imposed by retail chains on their suppliers that are the biggest concern . " And they are n’t necessarily unvarying , " explains Peter . " One does n’t require to see one active pith ; the other prohibits use of another . Through trade and our unmediated customers , these varying requisite finally encounter their way to us . It makes plant life security much more complex . "
Getting take off with Aphiscout early onThose measure are in particular helpful when it comes to aphid control . Working with advisor Marjolein van der Knaap , Anthura is presently investing to a great extent in an access being trace by one of the company ’s departments . In the department in head , a 1.4 - hectare area , pot sizes are larger and flora remain for tenacious than median . Anthura is essay to avoid all employment of pesticides in the department this season and is inaugurate natural enemies much earlier . " We started with Aphiscout in week 5 with a dose of a half parasitic wasp per straight metre and reintroduction every two weeks . The five natural enemies in Aphiscout should be able to keep the aphids under control for as long as potential . Here , we are tackle the green and ruddy peach aphid , cotton aphid , and pitch-dark bean plant aphid . "
An ambitious goalAs soon as a certain mintage of aphid commence to develop more sharply , Anthura will add in a specialist natural enemy . That would usually be Aphiphar or Ervipar . The troupe is also keep Aphidend and Chrysopa on hand to harness and clear up any hotspot . " We require to use this approach to take things as far as we perhaps can , but it is a little tense , " explains Peter . " We go for that it will work out in this section . But will it work in the other departments where we have little plant life material and where we have larger social movement and therefore a greater likeliness of cross - contaminant ? Success is not an automatic guarantee . " Nevertheless , Peter Vogel and Marjolein van der Knaap hope that at the end of 2020 , they will be depend back on a success story . Peter remain , " That would mean that we did n’t have to use any pesticides against the aphid . It ’s sure ambitious , but we postulate to make progress with the biology , thing have to move at a faster stride . "
The greenhouse in which Anthura is investigate aphid ascendance . Aphiscout is the standard natural enemy ; Aphiphar and Ervipar are used to harness specific aphid types .
Serious challengesThe fellowship is constantly looking for way to make anthurium cultivation more sustainable . Intensive exploratory survey is deport out every week , including in the dispatch department , which is effectively a word form of export checkout . " Some of our client have to work with our product for more than 30 weeks so it demand to be clean . industrial plant that appear to be damaged by whatever pest , no matter how modest , are pulled out and put away . " And plants that have left the nursery are not , in principle , returned to the greenhouse so as to prevent contamination from the dispatch area to the greenhouse . The cover department at Anthura uses natural enemies , and breeders depend closely at the pest sensitiveness of miscellany in ontogeny . " By using plant life sap analyses , we attempt to bring out the links between nutrients on the one paw and resilience , growth , plant quality , and infestation in the tailflower on the other . We do everything we can , and we ’re happy to do so . The market is now extremely illiberal and that pose serious challenge to us and our client . It needs to be addressed . "
