Biopesticide compositions comprising plant extracts and phytosanitary use thereof
A biopesticide composition contains a synergistic bioactive core consisting of essential oil, oleoresin, aqueous, alcoholic or hydroalcoholic extract of root or rhizomes of Zingiber officinale Roscoe and cinnamaldehyde or source of cinnamaldehyde. The composition may contain at least one secondary component and/or inert substances. A method is used for obtaining the biopesticide composition. The biopesticide composition is used in agriculture, parks and sports facilities against pests belonging to the whitefly group.
1 . A biopesticide composition consisting essentially of a synergistic bioactive core, consisting essentially of:
a) an essential oil, an oleoresin, an aqueous extract, an alcoholic extract or a hydroalcoholic extract of the root or rhizome of Zingiber officinale Roscoe;
b) cinnamaldehyde or an essential oil or oleoresin of Cinnamomum sp.; and
c) soy lecithin in solid or liquid form, wherein the soy lecithin consists essentially of hydrolyzed lecithin or partially hydrolyzed lecithin.
2 . The biopesticide composition of claim 1 , wherein the essential oil, the oleoresin, the aqueous, the alcoholic or the hydroalcoholic root or rhizome extract from Zingiber officinale Roscoe is present at 0.1%-99.8%, the cinnamaldehyde or the essential oil or the oleoresin of Cinnamomum sp. is present at 0.1%-99.8%, and the soy lecithin is a solid or a liquid hydrolyzed soy lecithin or a partially hydrolyzed lecithin present at 0.1%-99.8%.
3 . The biopesticide composition of claim 1 , wherein the essential oil or oleoresin of Cinnamomum sp. consists essentially of cinnamaldehyde.
4 . The biopesticide composition of claim 3 , wherein the cinnamaldehyde or the essential oil or oleoresin of Cinnamomum sp. is in a free form.
5 . The biopesticide composition of claim 1 , wherein the biopesticide further consists essentially of a second component selected from the group consisting of geranial-citral A-, neral-citral B-, saponins, benzyl alcohol, benzyl benzoate, benzyl acetate, eugenol, 1,8-cineole, thymol, geraniol, geranyl acetate, short-chain fatty acids, long-chain saturated fatty acids, and unsaturated fatty acids.

Salvia sp., Satureja sp., Schoenocaulon sp., Trigonella sp., Thymus sp. and Vitis sp.
7 . The biopesticide composition of claim 5 , wherein the second component is obtained from a plant selected from the group consisting of Cymbopogon sp., Litsea sp., Aloysia sp., Ocimun sp., Melissa sp., Citrus Sp., Cinnamomum sp., Syzygium sp., Curcuma sp., Zingiber sp., Ocimum sp., Cyamopsis sp., Quillaja sp., Trigonella sp., Saponaria sp., Crocus sp., Yucca sp., Beta sp., Hedera sp., Polygala sp., Primula sp,, Jasminum sp., Eucalyptus sp., Salvia sp., Thymus sp., Curcuma sp, Rosmarinus sp, Artemisia sp., Rosa sp., Geranium sp., Pelargonium sp., Persea sp., Glycine sp., Helanthus sp., and Olea sp.
8 . The biopesticide composition of claim 7 , wherein the second component is in a free or an encapsulated form.
9 . The biopesticide composition of claim 1 , further consisting essentially of organosiloxanes.
10 . The biopesticide composition of claim 1 , further consisting essentially of carboxymethylcellulose, sodium carboxymethylcellulose, and microcrystalline cellulose.
11 . The biopesticide composition of claim 1 , further consisting essentially of a component selected from the group consisting of maltodextrins, cyclodextrins, lecithins, vegetable oils, silica gel, colloidal silica and silicon dioxides.
12 . A solution consisting essentially of the biopesticide composition of claim 1 , wherein the essential oil, the oleoresin, the aqueous, the alcoholic or the hydroalcoholic root or rhizome extract from Zingiber officinale Roscoe is present at 0.1%-99.8%, the cinnamaldehyde or the essential oil or the oleoresin of Cinnamomum sp. is present at 0.1%-99.8%, and the soy lecithin is a solid or a liquid hydrolyzed soy lecithin or a partially hydrolyzed lecithin present at 0.1%-99.8%.
