Abstract

Preparations are described which contain DOLLAR A A) one or more pesticides and / or one or more phytohormones, DOLLAR A B) one or more amine oxides and DOLLAR A C) one or more anionic surfactants DOLLAR A.

Description

The Invention relates to improving the effect of biological activity of pesticides or pesticides (e.g. acaricides, bactericides, Fungicides, herbicides, insecticides, molluscides, nematicides and rodenticides) and phytohormones in the presence of a mixture of an amine oxide and an anionic surfactant.

Pesticides or pesticides are chemical or natural substances found in plant cells, - tissue or parasitic Organisms enter or damage the plant or damage it to destroy.

The largest part herbicides are pesticides, followed by insecticides and Fungicides. The main herbicides are chemical substances, the on the transport system of plants, for example by a Inhibition of photosynthesis, fatty acid biosynthesis or amino acid biosynthesis, act and inhibit nucleation and growth until death of the plant.

phytohormones control physiological reactions, such as growth, flowering rhythm, Cell division and seed maturation.

Around to ensure, that pesticides and phytohormones are technically applicable and that biological effectiveness is optimally exploited Preparation of the agents containing these substances mostly surfactants added as emulsifiers, wetting agents or adhesives.

The font US 5,858,921 teaches that by adding water-soluble, long-chain alkyldimethylamine oxides and water-soluble quaternary alkylammonium halides to the formulation, one can reduce the concentration of glyphosate without reducing biological activity. In US 5,750,468 Glyphosate formulations are described which contain tertiary or quaternary ether amines as adjuvant. Organosilicones show good wetting and adsorption capacity, as shown in numerous documents, for example WO 99/56543 and US 5,821,195 , A disadvantage is the sensitivity of the silicones to hydrolysis, both in the acidic medium at pH 2 to 5 and under basic conditions.

It there was the task of new auxiliaries for pesticides and / or phytohormones to develop their activity increase, in a similar way Dimensions like Silicone surfactant the surface tension greatly reduce the aqueous agents containing these substances without decomposing under acidic or alkaline conditions, as well as economical, easy to use and well tolerated by humans and the environment.
