Description
EXAMPLES
Preparation Examples
P.1—Preparation of an Abamectin Millbase
(1) In a suitably-sized vessel, polyarylphenol alkoxylate (Soprophor BSU, 28.4 g) and polyarylphenol alkoxylate phosphate (Soprophor 3D33, 18.9 g) were added to potable water (622.5 g) and mixed. Propylene glycol (94.7 g), antifoam (Antifoam 1510, 3.8 g) were further added with mixing, followed by Abamectin (900 g). The pH of the mixture was adjusted to approximately pH 6 using sodium hydroxide (25% in water, 1.2 g). The crude suspension was first passed through a Dyno-Mill (0.6 liter mill chamber volume) to reduce particle size of the suspended particles below 50 micrometers, followed by milling in recirculation mode on Netzsch Lab Mini Zeta IIE mill until the particle size of the suspended particles was below 1.5 micrometers (X.sub.95).
P.2—Preparation of Example 2
(2) In a suitably-sized vessel, propylene glycol (31.3 g), polyarylphenol alkoxylate (Soprophor BSU, 6.2 g), polyarylphenol alkoxylate phosphate (Soprophor 3D33, 22.5 g), polyoxalkylene sorbitan ester (Tween 80, 127.7 g), preservative (Proxel GXL, 0.6 g) and antifoam (Antifoam 1510, 1.3 g) were mixed using a Cowles impeller. Potable water (442.0 g) and Abamectin millbase (P.1, 120.0 g) were added with continued mixing. Thickener (Kelzan, 1.9 g) was added with mixing for one hour to assure satisfactory dispersion.

Active ingredient (D) (2442.3 g) was added until well-mixed. The pH of the crude suspension was adjusted with sodium hydroxide (25% in water, 8.6 g) to approximately 4.6. The suspension was milled with two passes through a Dyno-mill (0.6 liter mill chamber), resulting in particle size of 8.0 micrometers (X.sub.95) to yield a millbase of the active ingredient.
(6) Step 2: Thereafter, in a suitably-sized vessel, potable water (6700.0 g) and polyoxyalkylene sorbitan ester (Tween 80, 1996.0 g) were added with moderate agitation to homogeneity.

Dilution Tests:
(18) Dilution tests were carried out room temperature. Using an Eppendorf pipette, 4 mL of each formulation was diluted into 96 mL of water in a 100 mL glass graduated cylinder. The water having different levels of water hardness, e.g. 50 ppm, 342 ppm and 1000 ppm corresponding to concentrations of divalent ions (namely calcium and magnesium) was used. The time intervals were chosen to simulate diluted product standing over a typical “break” for the applicator (1, 2 or 4 hours) and overnight (24 hours). The dilutions were inverted 20× and allowed to stand. After standing for the desired time, the cylinders were noted for the volume of settled sediment and after the 24 hour reading they were subsequently subjected to cycles of inversions until the bottom of each cylinder was visually free of sediment. Inversions were performed manually (see Table X & Y for the results).

Example B1
Translaminar Test Against Two Spotted Spider Mite Tetranychus urticae on French Beans (Phaseolus vulgaris)
(21) The underside of 2 week old bean plants was infested with a mixed population of T. urticae. The border of the underside of the leaves is surrounded with a gum barrier to prevent the mites to move to the upper side of the leaves. One day after the infestation plants were treated with a track sprayer from the top with 200 L/ha of Example 2 products containing different amounts of Penetrator Plus. Plants were incubated in the greenhouse for 9 days and the evaluation was done on mortality against eggs and mobile stages (see Table A for the results of ABA efficacy).
Example B2
Control of Tetranychus Sp. Adults on Vegetables
(22) In a plot size of 14 m2, two foliar spray applications of each composition were made at a treatment rate of 9 grams/ha (second was 7 days after the first application). Each treatment was done in three replicates. Each adjuvant was added to Example 1 in a tank-mix based on 17 ml product/ha. First application was conducted 71 days after transplanting and the evaluation was done on mortality against mobile stages by taking 20 leaves from each plot at different intervals (see Table B for the results).
Example B3
Control of Colorado Potato Battle on Potatoes
(23) In a plot size of 7.5 m2, one foliar spray application of each composition were made at a treatment rate of 1 grams/ha. Each treatment was done in three replicates. Each adjuvant was added to Example 1 in a tank-mix based on 2 ml product/ha. The application was conducted 53 days after planting and the evaluation was done on mortality against larvae by counting the live larvae present per plot at different intervals and converting the data in % of control (see Table C for the results).
Example B4
Control of Liriomyza trifolii Pupae on Chrysanthemums
(24) CHRYSANTHEMUMS potted plants were infested with a very high population of adult leafminers allowing them to lay eggs. Four days after the initial infestation plants were sprayed using a CO2 compressed backpack sprayer with an application volume of 1800 L/ha. Plants were incubated in the greenhouse for 9 days after the application and the evaluation was done by counting the number of pupae per plant obtained for each treatment (see Table D for the results).
Example B5
Residue Study
(25) In a plot size of 25 ft×5 ft with 2 rows of Romaine lettuce (30″ row spacing, 8″ plant spacing so ˜70 plants/plot), a single application of a treatment listed in Table below was made as a post foliar broadcast spray at a rate of 0.038 lb. a.i. per acre. Each treatment was done in two replicates with a control in each replicate. A minimum of ˜3 lb of lettuce leaves were collected for each sample. Samples were harvested at 0, 0.25 (corresponding to 6 hrs), 3, 7, 14 and 21 days after last application (DALA). The O-DALA samples were harvested as soon as the spray dried. Samples were transported frozen and were prepared by grinding the samples with dry ice using a tabletop mill. The abamectin residue was analysed using a HPLC-Fluorescence Method (see Table E for the results).

Example B6
UV Degradation Study
(27) Photostability was assessed using an Atlas SUNTEST XLS+ unit (Part number 55007820) which utilises a xenon arc-lamp and a Special UV-filter (Part number 56052371) to simulate natural sunlight in both spectrum and intensity.
(28) Treatments were diluted either in ultra-pure water (or in ultra-pure water containing 0.1% Penetrator Plus) to give dilutions that were 125 ppm wrt abamectin. 8×2 ul drops were dispensed using a Hamilton PB600 repeating dispenser fitted with a glass 100 μl Hamilton syringe onto pre-scored glass microscope slides—typically seven or eight for each treatment. These were allowed to dry prior to being covered with clean UV transparent silica slides to minimise volatile loss from the deposit. One slide for each compound was not irradiated and designated as time zero (T0). The other prepared slides were placed in the SUNTEST XLS+ on a water-cooled sample table (attached to a circulating water bath set to 15° C.) and irradiated for time periods ranging from 30 minutes up to 43 hours.
(29) To quantify the amount of compound remaining, one slide was removed for each treatment from the SUNTEST unit, broken in half across the shaft of a small spatula, sandwiched with the clean sides together and placed in a 60 ml wide necked glass screw topped jar. The silica slide was rinsed with 2×2.5 mls of 50:50 (80/20 MeCN/THF): 0.1% H3PO4 into the jar, the lid replaced and the jar sonicated for 30 minutes. All jars were left standing at room temperature in covered boxes prior to analysis by LC with MS detection without further preparation (see Table F for the results).
Example B7
(30) Two golden Delicious apple plants grown outside in a propagation container (1-2 years old) were treated with the products. The treatment areas for new and old leaves were defined and marked before product application. A horizontal band was marked on each leaf (approximately ¾ of the way down from the leaf tip) with a permanent marker pen. All treatments were applied using a hand held pipette to the marked areas on each leaf as 10×0.5 ul droplets (corresponding to 25 ug Al per leaf) with four replicate leaves per treatment, and the plants left outside. The products were AGRIMEK, Example 2, and Example 2 with 0.25% v/v Horticultural spray oil (i.e summer oil). After 1, 3 and 6 days after treatment, abamectin residues were assessed either on the leaf surface or inside the leaf tissue on all four leaves per product treatment. Surface analysis involved washing the leaf with acetone, followed by a chloroform and then LCMS, while inside the leaf tissue analysis involved freezing the leaves, homogenising in 5 ml acetone, centrifuging and 1 ml of the resulting supernatant used for LCMS analysis (see Table G & H for the results).
