Description

EXAMPLE A

[0198] Production of Fatty Acid Derivative

[0199] A salt derivative of fatty acids can be prepared by the following method. This fatty acid salt derivative is obtained by mixing in a reactor a selection of fatty acids (C14-C18) derived from olive oil following oil hydrolysis whereby the glycerine is separated from the fatty acids and the fatty acids are subjected to fractional distillation in order to achieve the required specification. The fatty acids are made to react in a temperature controlled blending vessel with such quantity of potassium hydroxide and water for the production of the liquid fatty acid salt until solubilization of the components occurs and a liquid is produced that will readily form a true solution when diluted in water at the recommended rates of application for use in the field.

EXAMPLE B

[0200] Myzus persicae—Spray Test

[0201] To produce a suitable spray solution the active compound or active compound composition is diluted with water to the desired concentration. Penetration enhancer (RME=rapeseed oil methyl esters) in a dosage of 1000 ppm is added to the desired concentration if necessary.

[0202] Cabbage leaves (Brassica oleracea) which are heavily infested by the green peach aphid (Myzus persicae) are treated by being sprayed only on the downside of the leaves with the preparation of the active compound of the desired concentration.

[0203] After the specified period of time mortality in % is determined. 100% means all the aphids have been killed; 0% means none of the aphids have been killed.

[0204] According to the present application in this test e.g. the following combination shows an improved onset of efficacy in comparison to the single compounds:

TABLE-US-00002 TABLE B-1 Myzus persicae - spray test Concentration Efficacy in % Compound in ppm after 1 day Movento 240 SC * 20 13 Flipper (EW 479.8 g/l) 5000 7 Movento 240 SC * + 20 + 5000 40 Flipper (1:250) According to the invention

TABLE-US-00003 TABLE B-2 Myzus persicae - spray test Concentration Efficacy in % Compound in ppm after 2 days Movento 240 SC * 20 57 Flipper (EW 479.8 g/l) 5000 33 Movento 240 SC * + 20 + 5000 70 Flipper (1:250) According to the invention

TABLE-US-00004 TABLE B-3 Myzus persicae - spray test Concentration Efficacy in % Compound in ppm after 3 days Movento 240 SC * 20 92 Flipper (EW 479.8 g/l) 5000 33 Movento 240 SC * + 20 + 5000 96 Flipper (1:250) According to the invention

TABLE-US-00005 TABLE B-4 Myzus persicae - spray test Concentration Efficacy in % Compound in ppm after 4 days Movento 240 SC * 20 98 Flipper (EW 479.8 g/l) 5000 33 Movento 240 SC * + 20 + 5000 99 Flipper (1:250) According to the invention * 1000 ppm RME added

[0205] For the examples, the Product Flipper® (AlphaBioControl) was used.

[0206] The product Movento 240 SC is commercially available and comprises compound of the formula (I-4).

[0207] Flipper® (=Flipper): An emulsion in water (EW) insecticide containing 479.8 g/l plant origin Carboxylic Acid Potassium Salts C14-C20.
