Traditionally , whitefly in genus Gerbera is one of the regular but uninvited guest . Much is possible in terms of biologic controller , but the scope of curative that can be grabbed at any metre is find smaller and smaller . In short , it is a challenge , and it is under these consideration that , at the hint of supplier Van Iperen , Eric Kerklaan of HortiPro came for coffee at EveryD Flowers in De Lier .
HortiPro is a company specialise in biological harvest protection and all kinds of adjuvant and pheromone technology . Hortipro R&D was bet for a companionship shin with whitefly and with which they could work together to chance an effective control condition . The program was to develop a unexampled pheromone , which , whizz along out , would be another footstep towards the fullest possibleIntegrated Crop Management .

After a class or so of testing and constant counting and exploratory survey , we can report it worked . At the end of this yr , the pheromone ( PheroDes monitoring scheme for greenhouse whitefly and PheroBem for monitor for Bemisia , or tobacco whitefly ) will be on the market . Great to mention , moreover , is that it was develop here , at this garden , and in close cooperation between Eric Kerklaan and Lennart Simonse of HortiPro on the one handwriting and Hen Groenewegen and Marian van Bergenhenegouwen of EveryD blossom on the other , and of course entirely for the benefit of both parties .
You pipette the pheromone onto a strip of absorbent cloth , which you then put into a dispenser . Inside it is a cakehole through which the pheromone can evaporate . You put the whole thing in a 14 mm jam in a sticky trap , which tempt the adult whiteflies to a yellowish viscous trap . As a lineal answer , a large part of the whitefly population is captured . So , where hoi polloi used to be frightened to death if there were 100 on a pasty ambuscade , they are no longer surprised . Especially for Bemisia tabaci , which is more difficult to control than the ' normal ' greenhouse whitefly , this is a manna from heaven .
" We ’ve learned a lot in recent years , " Hen and Marian , grower and creditworthy for crop protection , respectively , tell us . " We are there before in terms of spot pests , especially because we are scouting more . So we have a good depiction of what is flying around . Therefore , unlike before , we are less behind the times , and that is essential because interpose at a late degree is black for your biological science . Because we catch a mountain of flyaways , we have also exchange the spraying schedule substantially . We use almost no chemical any longer , compensate is done almost solely with green agents . "

Not on holidayIn short , it may be called a achiever tarradiddle , but it does have one downside : you ca n’t go on vacation . Eric : " pheromone can be a solid basis for a healthy crop protection scheme , but you have to stay on top of it . Preferably with regularity , numeration , and scouting should be done . Not once in a while , not just when you have time , but systematically . If you slow down off in this deference and a plague returns , you will straight off fall behind again . Even , or perhaps especially , when you think you are disembarrass of something , it is important not to slack off . "
