Welcome to the first Organic Field Days 

On  21 and 22 June 2017, more than 200 companies, associations and organisations will be presenting what they have to offer in the organic agriculture arena at the first ever nationwide Organic Field Days. Most exhibitors come from the sectors of agricultural engineering, inputs and seeds/vegetative propagation material. Eleven additional categories ranging from consultancy to research and certification all the way to animal husbandry and marketing will be represented, reflecting the rich spectrum of participants. The Organic Field Days will inform across a wide range how organic farms can further develop. Central themes will be, for example, organic breeding, nutrient management and conservation tillage, as well as, agriculture and nature conservation.

The multicopter was tested after the winter and a training course took place.

First observation of the european corn borer

Currently the nature is about two weeks ahead. This advance won’t be hold, but today we have already done the first survey of the overwintering corn borer. At a location near Walldorf in Germany, we found very quickly corn stubbles with larvae. The larvae are all healthy and mobile, but a few of them are already in hook-position. On a location near Mannheim, we have also found easily healthy larvae.

Spring is back… And the moths too!

The winter was relatively cold compared to the previous year, but it did not affect the moths in storage. Both, clothes moths and food moths, fly now more intensively in households and in heated storages. In a few weeks moth will fly in the unheated storages too... therefore all storages should be equipped with active pheromone traps and a visual check should be done regularly. If possible, the infested product should be removed and the last instar larvae, which is leaving the food source to find a place to pupate, should be catched as far as possible in order to minimize the infestation.

Top 3

The trials to optimize the control of tomato leafminer Tuta absoluta and the tomato looper Chrysodeixis chalcites are coming to an end. Both are by now important pests in the culture of vegetables in greenhouses and cause enormous damage. Only a consequent control secures the harvest. In addition to a few Trichogramma-species, the use of the braconids was also tested.

We use the results for the improvement of beneficial application. Chrysodeixis chalcites, the tomato looper is a common harmful moth in greenhouses. The larvae are polyphagous and cause serious damage to the plants such as geraniums, herbs and tomatoes. Under warm conditions a continuously development is possible, but they do not tolerate frost. Tuta absoluta is found in tomato cultures, but it also damages peppers, aubergines and other vegetable crops. In the worst case, the damage can mean the total loss of the harvest. No. 3 is a customer order to optimize the control in corn.

GBOL-Project: Current Trichogramma season comes to an End

Autumn peak is over and so we are going to stop the luring activities at the end of October. Round about 1300 samples were prepared for the gen based species identification (Barcoding). 130 Strains were still alive and were so available for further tests for selecting new candidates for biocontrol.  Baiting of Trichogramma was more complicated than in the years before. Less Trichogramma were detected although in places with high Trichogramma activity in 2014/15.

Maize: a green bridge 

How is life in a maize field? Which animals can be found and where do they come from? Follow us into the maize field and be inspired by the diversity of life.

A video from the Deutsches Maiskomitee e.V. (DMK) in Bonn about the biodiversity in a corn field: maize - the green bridge

Also the latest Movie of the DMK is now online: Biological plant protection for corn. Trichogramma - little helper with big effect

What are the options for the control of the European corn borer (ECB), which is the main pest species in corn? You can find the answer in the latest movie of the German corn committee: The application of Trichogramma-wasps - small helper with a big effect.

The usage and application of chemicals pesticides by farmers is part of a controvers public discussion. But are there options for those who decided to reduce the application of chemical pesticides in the control of the ECB? The answer is yes. Trichogramma wasps, a natural enemy of the ECB attacks and kill the eggs of the ECB. The application of the 0.5 mm small wasp is an established technique of biocontrol. Now a new application technique with drones allows the treatment of 1ha within 5 minutes.

The new Movie gives you an overview about the life cycle of the ECB and Trichogramma with insights and detailed film sequences of the usage and activity of Trichogramma-wasps in the field. One highlight is the operation of the drone under working/field conditions.
