Abstract
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.
Claims9
An insecticidal or acaricidal composition, comprising
- an emulsifiable concentrate comprising more than 50 wt % limonene as an active ingredient,
- between 12-20 wt % of an emulsifying fatty alcohol ethoxylate surfactant having a hydrophilic-lipophilic balance (HLB) between 7 and 12, and no emulsifying surfactant having an HLB of 12 to 16,
- less than 10 wt % solvent,
- between 15-25 wt % of an anionic surfactant wetting agent;
- wherein all weights are based on the total weight of the composition,
- wherein the insecticidal or acaricidal emulsifiable concentrate, upon dilution with water and spraying as a water diluted spray, provides a dose rate of 60 g to 1,800 g limonene per hectare such that the composition is effective in the treatment of Acari or mites, Coccoidea or scales and Aleyrodidae or white flies, and
- wherein the insecticidal or acaricidal emulsifiable concentrate is stable after 14 days at a temperature of 0° C., −5° C., room temperature or 54° C.
