The Apple mealybug Phenacoccus aceris was verified as the vector of the Little Cherry Virus-2 (LChV-2) in Baden-Württemberg. However, this does not exclude the participation of even more different vectors. Because the Apple mealybug is more spread than presumed as of yet, this vector should be specifically controlled as well as fought in cherry orchards. If planting new cherry orchards it must be strictly adhered to virus-free, certificated plant matter, so that in areas free from Little cherry an epidemic as in the "Altes Land" can be avoided. © 2011 Springer-Verlag.

Since 2009 the production area of soybeans in Germany is growing, mainly in the South but also in the eastern part and a little bit everywhere, where the climatic conditions are appropriate. With the help of national programs has been established the necessary database for a qualified counselling of farmers about soybean-cultivation. It is brought to the farmers and the transformation industry by a national demonstration and development project. German soybeans will not compete with GMO-Soybeans and not even with the non-GMO soy from overseas but aim at the regional short circuit and organic markets which are even more deficient than the conventional. With just 10 000 ha in 2014, thereof 25% organic, German soybean area is still far away from the climatic potential that is indicated by the area of maize harvested as corn (2008-2014 around 500 000 ha). In practice, the potential area for soybean cultivation would be reduced to 20% of the corn acreage 500 000 ha or 100 000 ha, if prices guarantee a profitability that is sufficient to compete with other field crops. For the non-GMO-programs of the big distributors a bigger production base will be necessary. This is proposed by the certified soybean from Danube-Soya that tends to englobe also other European soybeans (e.g. France). Given the greening of EU-politics as well as the exchange rate of the US-Dollar, the actual perspectives for a further growth of the German and European soybean area are quite well. It will now be necessary to work on the marketing of this growing production on all levels: regional, national and European. © J. Recknagel, published by EDP Sciences, 2015.
