The aim of the "MartA (Smart Spraying)" project is to identify diseased plants immediately after infestation and treat them with pesticides at the ideal time. Together with the industry partners Bosch and Cubert, the researchers are developing sensors and algorithms that make this possible. The project has already been successful for the sugar beet disease cercospora, and promising progress has also been made against three wheat diseases.
The German life science company Bayer and the U.S. developer of biopharmaceuticals Arvinas are planning to adapt molecules of the cell's own system and use them to remove foreign or no longer needed proteins in order to protect agricultural plants from pathogens, insect pests and wild herbs. To this end, both companies have now announced the foundation of the joint venture Oerth Bio (pronounced "Earth").
Nitrogen deficiency restricts the growth and yield of plants. That is why the addition of nitrogen is a common part of agricultural practice. However, researchers from the Zuse-Gemeinschaft report that the effect is reversed and the yield when as little as 135 kilograms are used per year and hectare. They also present new applications for field beans and a device that analyzes the ingredients and shelf life of food.
Scientists from Potsdam, Berlin and Grenoble were able to use ultra-fast 3D neutron imaging to visualize the transport of water in the soil and the subsequent absorption by the roots of lupines.
That insect decline and species extinction are a fact has been shown by numerous national and international studies. Now German scientists are once again drawing attention to the loss of species with a large-scale biodiversity study. A research team led by the Technical University of Munich (TUM) has come to the conclusion that the decline of insects in Germany is even more extensive than previously assumed. "Previous studies [...] either focused exclusively on biomass, i.e. the total weight of all insects, or on individual species or species groups.
For many pollutants such as pesticides, the legislator has set threshold values. Below these limits, exposure is considered harmless. However, this does not seem to apply to many living organisms, including humans, as ecotoxicologists at the Helmholtz Centre for Environmental Research (UFZ) have now been able to show.
The genetic engineering ruling of the European Court of Justice in the summer of 2018 has political repercussions: the European Council, the EU's leading political body, has asked the EU Commission to clarify how "novel genomic techniques" are to be legally classified and regulated in the future. The results of this study are to be presented by April 2021 - including proposals and an impact assessment.
Peppermint, lemon balm, wolf’s bane or chamomile are popular medicinal plants. They are used to soothe the symptoms of diseases in teas, but also in pharmaceuticals. But their cultivation is difficult. Even the smallest contamination by weeds can impair the effect of the medicinal plants. In the joint project Optimech, a team led by the University of Bonn is now investigating how medicinal plants can be cultivated in a way that is as soil-friendly as possible without having to use herbicides.
There are many environmental factors like drought and overfertilization that put plants under stress. In such cases, a complex signalling cascade is triggered inside the plant. This stress management apparatus works the same for all land plants - in moss just as in rye. An international research team led by the Hebrew University of Jerusalem, in which the University of Göttingen participated, wanted to know exactly how stress management works. The scientists therefore focused on a specific gene for the receptor in this signalling cascade.
The industry is relying more and more on natural substances and, with this, satisfying consumer demand for more biobased and sustainably produced products. Plant-based products and ingredients are particularly in demand in the cosmetics industry. Through a new strategic partnership with the French company Plant Advanced Technologies (PAT), the Swiss chemical group Clariant intends to expand its involvement in this business field.
