Embodiment Construction

[0076] research material

[0077] The studied sophorolipids can be described by general formula 1 and / or 1a.

[0078] On the basis of the substrates glucose, sunflower oil, rapeseed oil or olive oil (comprising mainly oleic acid as acid component), crude products are prepared by fermentation with Candida.

[0079] Growth medium contains the following components:

[0080] -10g / l glucose ((D)+glucose*1H 2 O)

[0081] -7.5g / l YNB (yeast nitrogen source)

[0082] -2g / l yeast extract

[0083] The 1.11 medium was autoclaved in a 21 volume fermenter and inoculated with an exponential phase preculture from the same medium. The temperature was set to 30°C. The pO 2 Maintain at 30% relative saturation, but the stirrer speed is not lower than 200rpm. During the biomass formation phase, the pH dropped to 3.5 and was maintained at this level by adding NaOH. At the end of the biomass formation phase (existing glucose is depleted, characterized by pO 2 rise or pCO 2 drop), the p...

Abstract

The invention relates to the use of sophorolipids as adjuvants in combination with pesticides as a tank mixture additive and / or as a formulation additive for plant protection and the industrial non-crop field.

Description

technical field [0001] The present invention relates to the use of sophorolipids and / or derivatives and compositions thereof as formulation additives and / or tank mixing additives (also known as adjuvants) for pesticides or pesticide mixtures. Background technique [0002] In crop protection, in pest control compositions and also in the industrial non-crop field, the biological activity of such pesticides or pesticide mixtures is generally improved by using so-called adjuvants or auxiliaries or additive substances. The activity is also commonly referred to as potency. Center for Pesticide Safety (PSD, the executive branch of the UK's non-state public organization Health and Safety Committee) defines an adjuvant as a substance other than water that does not have pesticide activity itself, but enhances or supports the efficiency of a pesticide (http: / / www.Pesticides.gov .uk / approvals). These substances are added to aqueous spray solutions immediately prior to delivery and spr...
