Embodiment 1

[0177] A herbicidal suspoemulsion composition containing glyphosate, acetochlor and atrazine as active ingredients together with the safener clofenfur was prepared by the following procedure. "Surfactant M" is an activator containing 70% polyoxyethylene (15) tallow amine (HLB = 14), with the balance being polyethylene glycol for most formulations.

[0178] In a container with a stirring tool, 193 g of Monsanto's MON0139 (62% aqueous solution (by weight) of glyphosate isopropylamine salt), 134 g of Surfactant M, 15 g of propylene glycol, 4 g of sodium sulfite and 1.5 g of BASF's Mazu TM DF 100S (organosiloxane defoamer) was added to 389 g of water to make an aqueous premix. To this aqueous premix was added 247 g of atrazine (97% purity) powder with an average particle size of about 10 μm, 1.5 g of calcium carbonate and 15 g of Floridin's Minugel TM 400 (colloidal attapulgite). Stirring was continued for 10 minutes.

Embodiment 2

[0183] Herbicidal suspoemulsions having the compositions shown in Table 2 below were prepared by a procedure similar to that described in Example 1. The stabilization system contains an anionic surfactant, Toximul from Stepan TM TANS-5 (alkylphenol ether sulfate / tallow amine ethoxylate of HLB=8) and two nonionic surfactants, Toximul of Stepan Company TM 8320 (butyl polyoxyalkylene block copolymer of HLB=12) and Toximul of Stepan Company TM SEE-340 (polyoxyethylene (20) sorbitan trioleate with HLB=11) mixture.

Embodiment 3

[0188] A herbicidal suspoemulsion composition containing the active ingredients glyphosate, acetochlor and atrazine together with the safener clofenfur was prepared by the following procedure.

[0189] In the first mixing bucket, combine 364.9g water, 131.5g MON 0139, 13.3g 50% aqueous sodium hydroxide solution, 10.0g propylene glycol, 1.0g sodium sulfite and 3.0g Henkel's Agnique TM DF 6889 (organosiloxane defoamer) was added together to make an aqueous premix. Preferably the water is added first and the MON 0139 last, but the order of addition is not critical.

[0190] In the second mixing tank, add 7.3g of clofenfur to 227.4g of acetochlor (93% purity), and stir thoroughly to ensure that clofenfur is completely dissolved in acetochlor, thus preparing an organic pre mixture. Then add the anionic surfactant Stepfac of 27.0g Stepan company under continuing to stir TM 8171 (polyoxyethylene (6) nonylphenol phosphate), then add 3.3g Toximul TM 8320 with Toximul TM Nonionic ...

Abstract

The present invention is a herbicidal composition containing glyphosate or glufosinate-ammonium, a chloroacetamide, and a triazine, wherein the composition has an aqueous phase, an oil phase, and is dispersed in the aqueous phase and/or particles in the oil phase and are stabilized by a stabilizing amount of one or more emulsifiers.

Description

field of invention [0001] The present invention relates to liquid concentrated herbicidal compositions which exhibit acceptable chemical and physical stability under normal storage conditions and are suitable as broad spectrum herbicides for application to plants and soil when diluted with an appropriate amount of water. More particularly, the present invention relates to liquid concentrated herbicidal compositions comprising at least three herbicidally active ingredients. background of the invention [0002] When crops are grown in a field, it is important to kill or control unwanted vegetation (weeds) growing in the field. If not controlled, weeds compete with crops for basic resources such as soil nutrients, water and sunlight. By removing some of these resources or reducing their availability to the crop, weeds can limit crop growth, resulting in reduced yields. [0003] Weeds that are used to control may also have other detrimental effects; for example, during importa...
