Identification of "Defense Primers" using OTR – Boosting the innate immune response for agro & pharma applications

The method developed at RWTH Aachen University enables the identification of immune primers using OTR monitoring in a new and very efficient way. Areas of application include plant protection, but also the pharmaceutical industry (preventive medical immune system priming).



Efficient and cost-effective in situ measurement of growth-related soil parameters

To obtain best quality and quantity results for plant growth in soils and substrates, knowledge of the water and ion content of the soil and thus the dosage of irrigation and fertilizer is fundamental. This is particularly true when we want to support sustainability and the preservation of resources, but also wish to increase yield.
At the Institute of Agricultural Engineering of the University of Hohenheim a technology has been developed that measures soil water content, suction tension and salt content simultaneously and on-site. Signal transmission and the evaluation can be performed telemetrically or via cable, on-site or remote. The technology uses laser diodes, no spectroscopy is required.



New process for creating storage-stable, 12-month non-perishable „ESL-H-Milk“

In order to increase the storage stability and shelf life of milk, a new treatment process has been developed at Hohenheim University, one that also requires comparatively low treatment temperatures.
The milk can be kept at room temperature for up to a year and yet impresses with its good sensory properties and low vitamin loss.



Poultry farming: Environmentally friendly method for controlling red mites

Red mites are the most common ectoparasites of poultry and cause substantial economic damage worldwide. Scientists at the University of Hohenheim have developed a method to combat red mites which utilizes the fact that the mites are sensitive to heat and that the parasite only visits the host at night for feeding and then hides in dark spaces near the host. The method presents hollow, perforated perches as appropriate hiding places where mites in all states of development are killed through thermal treatment. Because of the purely mechanical nature of the process there is no health risk for personnel. Since temperature and speed of the heating device are regulated by a PLC (programmable logic controller), farm workers are free to carry out other tasks while the treatment takes place.



Biological Varroose control through interference with reproductive behaviour of Varroa bee mites

Scientists at the University of Hohenheim, Germany, have developed the first biological and bee-friendly Varroose control method. The method exploits the fact, that female mites exude a pheromone which incites the mating behavior of the males.

After isolating the pheromone and identifying its components, followed another breakthrough with the discovery, that single components of the pheromone affect the mating behavior effectively, too. Currently the scientists run successful field tests using oleic acid, a low-priced component, which is unproblematic with regard to food regulations and suitable for application as a spray.
