Yields could decrease by as much as 50 to 100 percent due to the major reduction in pesticides allowed for crops such as roses, chrysanthemums, cucumbers, Brussels sprouts, spring-sown onions, tulips and ornamental shrubs. This could make Dutch cultivation unviable and even mean that cultivation stops altogether in the Netherlands.
Wageningen UR studied two scenarios that are currently on the table. Firstly the European Parliament’s position after the first reading of the common position of the European Commission and Council of Ministers (the 'EP-cut-off' scenario) and secondly the common position of Commission and Council of Ministers (the 'EC-CMR/ED' scenario).
The studies show that the EP-cut-off scenario will result in yields being reduced by 50 to 100 percent due to the banning of a large number of pesticides for roses, chrysanthemums, cucumbers, Brussels sprouts, spring-sown onions, tulips and ornamental shrubs. This makes cultivation in the Netherlands unviable and will have enormous consequences for the production of and international trade in these crops. Cultivation may even disappear from the Netherlands altogether, which would have a major economic and social impact.
Despite the fact that the number of pesticides that would be banned in the EC-CMR/ED scenario is much lower, this scenario would also have a considerable impact on most of the abovementioned crops.
In the proposal of the Council of Ministers and the European Committee for a new Crop Protection Regulation, the criteria for the approval of pesticides are no longer based on risk alone. Other criteria involved include the intrinsic carcinogenic, mutagenic, reprotoxic (CMR) and hormone disruptive (ED: Endocrine disruption) characteristics of substances. The European Parliament decided in autumn 2007 that more active substances should be banned from the EU.Research
Yield losses for seed potatoes, table potatoes, winter wheat, tomatoes and apples are estimated at 15 to 32 percent. The profit made from cultivating these crops will be significantly reduced, which will put pressure on viability and make it difficult if not impossible to pay fixed costs. In addition, with so many pesticides being banned in this scenario, other problems are likely to emerge as diseases, pests and/or weeds become resistant to the remaining pesticides and harder to control.
Other long-term effects are hampering weed management, a growing nematode population and an increase in diseases and pests that were also affected (side effects) by the former pesticides. The long-term effects of this study were not formulated into exact figures but are also likely to have a significant impact.EC-CMR/ED Scenario
Ornamental shrubs, spring-sown onions, roses and chrysanthemums will be affected by the lack of pesticides to such a degree that cultivation will result in losses or become economically unviable. Fixed costs will become hard or impossible to pay. There will also be yield losses in the cultivation of seed potatoes, table potatoes, sugar beet, Brussels sprouts, cucumbers, tomatoes and apples and these crops will become less economically viable. Only the cultivation of winter wheat will be relatively unaffected despite the fact that several pesticides will be banned for this crop as well.
This scenario may also lead to long-term effects including increased resistance and a growing nematode population.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
