Benefits of technology

[0007]In an embodiment, a pesticide composition includes a super high load mixed salt glyphosate soluble liquid formulation. An embodiment of a pe...

Problems solved by technology

Drawbacks to such pesticide compositions include retention of the spray drops on the target surface and incomplete incorporation into the target pest.
Further drawbacks include the limited time the active ingredient has to move into the pest due to the spray solution solidifying.

Formulations Including an Alkylamine Alkoxylate Phosphate Ester Surfactant Adjuvant

[0025]During a project to investigate the maximum loading possible for a soluble liquid glyphosate formulation, a composition was discovered that exhibited streaming birefringence. A mixed K:IPA salt of glyphosate with a high ratio of K was used with a surfactant blend of two surfactants. The first surfactant in the blend was a phosphate ester of a tallow amine ethoxylate. The surfactant chemistry for phosphate esters of tallow amine is disclosed in WO 01 / 11958A1, which is incorporated by reference herein in its entirety. The second surfactant in the blend was an alkylpolysaccharide.

[0026]Referring to Table 1, below, several pesticide formulations are listed in which the active ingredient was potassium glyphosate 58.0 wt. % active ingredient (ai), or potassium glyphosate manufacturer use concentrate, which corresponds to 47.5 wt. % glyphosate acid equivalent (ae), together with isopropylamine glyphosa...

Field Trials with Formulations No. 3 and 9

[0033]Field trials were run on Formulations No. 3 and 9 of Table 1, above, and Roundup® Original (RU Orig.) herbicide (which was applied at half label rates) to test for phytotoxicity and glyphosate efficacy. Roundup® Original is obtainable from Monsanto, St. Louis, Mo. Generally, plants were grown on test plots that were thirty feet long by ten feet wide and that included four thirty-inch width rows of plants. Three replicate test plots were used for each herbicide tested. The crop chosen for testing was a Roundup Ready® soybean (Monsanto, St. Louis, Mo.), which were at the trifoliate stage, approximately 12 inches tall. The weeds in the test plots were 6-12 inches tall. The weeds studied included Tall Waterhemp (AMATU), Velvetleaf (ABUTH), Ivyleaf Morningglory (IPOHE), Common Cocklebur (XANST), and Dent Corn (ZEAMD). One set of test plots was left unsprayed to act as a control—to monitor prevailing weed growth. Formulations were applied u...

Additional Pesticide Formulations

[0036]Pesticide compositions that exhibit streaming birefringence are not limited to a particular surfactant chemistry or active ingredient. For example, the surfactant compositions and / or the active ingredient compositions of Formulations 10-12 of Table 4, below, differ from that of Formulations 1-9.

[0037]Referring to Table 4, the active ingredient of Formulation 10 is potassium glyphosate 58.0 wt. % ai, which corresponds to 47.5 wt. % glyphosate ae. Generally, Formulation 10 was made by adding 15 grams of a lard DMAPA N-oxide surfactant to 85 grams of a 58% solution of potassium glyphosate in water. The blend was gently warmed to about 50° C. and it was stirred until uniform. The active ingredients of Formulations 11 and 12 were Metolachlor (98.7% ai, liquid technical) and Tebuconazole (96.5% ai, solid powder technical) respectively. Generally, Formulations 11 and 12 were made by mixing 0.05 grams of the respective active ingredient with 19.95 gram...

Abstract

A pesticide composition exhibiting streaming birefringence and methods for making the pesticide composition are disclosed. In one embodiment, the pesticide composition comprises an active ingredient and a surfactant adjuvant.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 826,717, which was filed on Sep. 22, 2006.FIELD OF THE INVENTION[0002]This invention relates to the field of pesticide formulations and more specifically to pesticide formulations that exhibit streaming birefringence.BACKGROUND OF THE INVENTION[0003]Pesticide compositions have been used in agrochemical and related applications. Pesticide compositions typically include an active ingredient as well as an adjuvant. Active ingredients include herbicides such as glyphosate. An example of a typical adjuvant is a surfactant. Pesticide compositions are disclosed in U.S. Pat. No. 6,365,551; U.S. Pat. No. 6,881,707; U.S. Pat. No. 6,544,930; U.S. Pat. No. 5,468,718; and WO 2006 / 023431, which are each incorporated by reference herein in its entirety.[0004]Drawbacks to such pesticide compositions include retention of the spray drops on the target surface and incomplete incorpor...
