rent ’s straightaway take the sting out of this : Greenhouse grower certainly endure from recall flora shelter product approvals . They also have to switch cogwheel to keep pests and diseases under mastery . Applications have to stay within the legal frameworks . And their range of products has also become smaller . Jolanda Wijsmuller , Bayer : " It ’s a balancing bit for them . Yet they are less likely to go under than their colleagues in exposed cultivation . glasshouse growers are rosy to be able to apply several species of good insects and have increasingly begin using insect sack to keep harmful insects out of the glasshouse . And in plus , the clime in the greenhouse can be well control , which help oneself them come down disease pressure . A lot has been reach in greenhouse farming in that respect . "

Also , the risk of exposure of the emergence of resistances increase because switch options are virtually missing . This way , registered agents can become unusable as well . "
The crop protection industry is doing all it can to give horticulturists new options . Their efforts are based on both federal agent of synthetic and natural parentage . Traditional chemical substance companies have been investing heavily in the development of new green agent for over 15 - 20 years , but that challenge is perhaps even great than the growth of new synthetic agent . Major excogitation are yet to come .
" Compared to uncovered finish , natural - origination agents in greenhouse horticulture have a not bad chance of success in terms of strength because of curb conditions , timely monitoring of locations with plague and spray equipment that permit the entire crop to be decent cover , " Jolanda adds .
" We hear few cries for help from greenhouse growers than from the exposed harvest side . There , the situation is really very difficult . " Jolanda : " In this wet class , fungi will happen upon mercilessly . No crop can withstand that . "
Appeal to politiciansJolanda really makes an entreaty to politicians : " ensure to go and see what is going on in practice ; how serious the situation is . the great unwashed can stargaze about where they want to go , but they must n’t fall behind sight of reality . "
