AGRYPHAR SPRL (Seraing, BE)
Inventors:
Pirotte, Alan (Houffalize, BE)
The current invention concerns a composition, in the form of an emulsifiable concentrate, comprising more than 50% limonene as active ingredient and a surfactant system with an anionic wetting agent and a non-ionic polymeric surfactant and with less than 10 wt % solvent. The composition with high load of nature derived active ingredient remains stable, preferably even when subjected to cold storage. The invention also provides in the use of a limonene comprising composition as acaricide or insecticide, and in a method of treating plants and crops with a limonene comprising composition.

The present invention relates generally to adjuvants for agrochemicals. In particular, the present invention relates to the use of certain terpenic alkoxylates as adjuvants to improve the performance of agrochemicals and to agrochemical compositions containing such adjuvants.
The present invention provides mixtures comprising certain terpenic alkoxylate adjuvants A and an agrochemical component B. Component B is an agrochemical active ingredient. Suitable agrochemical active ingredients include insecticides, acaricides, nematocides, molluscicides, fungicides, herbicides, plant growth regulators as well as fertilizers and micronutrients.
It has now been found, surprisingly, that the agrochemical active ingredient - adjuvant mixture according to the invention can extend the range of action of the agrochemical active ingredient e.g. by achieving a synergistic effect. Thus, the rates of application of the components are lowered whilst the action remains equally good. Secondly, the active ingredient mixture still achieves a high degree of pest or weed control, sometimes even where the two individual components have become totally ineffective in such a low application rate range. This allows increased safety in use or any other advantages familiar to a person skilled in the art.
