Abstract: Extract of the seedless pod of  Gleditsia Amorphoides  and its use as an agricultural adjuvant,  characterised  in that it has a content of soluble solids between 250 - 270 g/kg; of triterpene saponins between 60 - 75 g/kg; a conductivity (5 Brix) of 6 +/- 4mS/cm; an absorbance at 400nm (with 1.1% of the product in water) of < 0.500 AU; a foam production (5 Brix) of 160 ml; a pH (direct) equal to 3 +/- 0.3; whilst its chemical determination in g per 100g of the extract expressed as elements is total Ni = 0.51; available P = 0.28; K = 1.22; S = 0.63; Mg = 0.08 and Fe = 0.0022; whilst available P (expressed as 05P) = 0.64 and K (expressed as KO) = 1.47; moreover, the total quantity of phenols is approximately between 8.5 and 10% and of tannins is between 0.9 and 1.5%. Said adjuvant extract, which is highly soluble in water, gives the following results when subjected to tests: Oral toxicity in rats >4000mg/kg; inhalatory toxicity at a maximum nebulisable concentration of 4.89 mg/l; Primary Dermal Irritation and Ames Test, Cytotoxicity: showing that it lacks toxicity. Its absorbance at 3 Brix is between 1,230 and 1,120, and 1 g/l of Na benzoate can be used as a compatible preservative. It is produced by treating the husk of the seedless pod of  Gleditsia Amorphoides.   
     For its use as a fertiliser, it is made up of two essential components, wherein a first component consists of the natural organic coadjuvant extract consisting of 30/60cc of an aqueous solution of said extract of the fruit of  Gleditsia Amorphoides  containing 250-270 g/kg of total soluble solids; 60-75 g/kg of triterpene saponins, and presenting a conductivity (5 Brix) of 5.6+/-4; an absorbance at 400 nm (with 1.1% of the product in water, v/v) of <0.500 AU; a foam production (5 Brix, ml) of >160ml; a pH (direct) of 3.9 +/-0.3 and a surface tension of 38 to 40 dyn/cm; whilst the second active component consists of 1000cc of a solution in pure water of granulated urea with a low Biuret content, < 0.5%, with a Ni content of 20%. Said solution is made up using pure water with pH 7 and with no hardness in the form of Ca+ and Mg+ ions. 
     For a glyphosate type herbicide at a proportion of 672 g of active substance/ha, 0.06% v/v of the extract is added as an adjuvant. 
     For formulations of herbicides, 1.0 a 1.5% v/v of the extract is added to the final formulation of the product. 
     In a pyrethroid type insecticide used for controlling the citrus leafminer  (Phyllocnistis citrello Staiton),  between 0.25 and 0.50% of the adjuvant is used with 0.15% of avermectin. 
     For a Paraquat type defoliant, the formulation comprises approximately 0.25% v/v of the aqueous extract, an emulsifiable oil at 1% and a 1l/ha concentration of Paraquat. 
     For a nitrogenated fertiliser, the formulation is made up of between 10 and 46 g/100g of organic Ni and between 30 and 60 cc of the aqueous extract, with a pH of 6.9, a Biuret content of 0.15g/100g and a surface tension of 36.6 dyn/cm. 
     For a spray solution, 30 to 60 ml of said aqueous extract is added directly for each 100 litres of solution. 
     Technical specifications: 
     It has a content of soluble solids between 250 - 270 g/kg; of triterpene saponins between 60 - 75 g/kg; a conductivity (5 Brix) of 6 +/- 4mS/cm; an absorbance at 400nm (with 1.1% of the product in water) of < 0.500 AU; a foam production (5 Brix) of 160 ml; a pH (direct) equal to 3 +/- 0.3; whilst its chemical determination in g per 100g of the extract expressed as elements is total Ni = 0.51; available P = 0.28; K = 1.22; S = 0.63; Mg = 0.08 and Fe = 0.0022; whilst available P (expressed as 05P) = 0.64 and K (expressed as KO) = 1.47; moreover, the total quantity of phenols is approximately between 8.5 and 10% and of tannins is between 0.9 and 1.5%.
