Definitions

• This invention relates to a method and composition for enhancing the efficacy of herbicides in particular herbicides selected from the group consisting of acifluorfen, its agriculturally acceptable salts, oxyfluorfen, lactofen, imazaquin acid and the agriculturally acceptable salts thereof, N-phosphonomethylglycine and its agriculturally acceptable salts thereof, mixtures thereof and the like.
• This invention also relates to a ready to use composition comprising an enhanced delivery system for herbicides.
• Herbicides may be applied to plants in a variety of methods including different formulations. Of these various methods, use of liquid and dry compositions are quite desirable. The particular formulation desired and resulting efficacy enhancement will greatly depend upon the weed species to be treated, environmental conditions, the geographical area and the climatology of the area at the time of treatment. In many areas of the world, it is highly desirable to apply a herbicide composition having rainfastness quality (adherence to foliage) in areas of high rainfall amounts or under conditions and timing where rainfall is highly likely following application of a herbicide. Further in some areas, it may be particularly desirable to apply herbicide compositions (typically a herbicidal composition) to vegetation which has a thick cuticle and therefore herbicide penetration may be somewhat inhibited.
• herbicide compositions typically a herbicidal composition
• compositions of this invention produced increased herbicide efficacy particularly in applications of a herbicide in accordance with this invention on rhizome johnsongrass, a narrowleaf perennial, and seedling johnsongrass, bamyardgrass and downy brome which are narrlowleaf annuals.
• Glyphosate N-phosphonomethylglycine
• glyphosate has low water solubility, and because of this, commercial formulations contain a water-soluble salt of glyphosate.
• glyphosate is formulated as the isopropylamine salt.
• humectants with certain herbicides is disclosed in "Additives in Herbicide Formulations", Andress G. Kanallopoulos, Sandos, Ltd. Agrochemical Department Switzerland Chemistry and Industry, 7 December 1974, which discloses on page 352 that humectants improve penetration of herbicides into plant leaves by preventing drying of spray deposit, thereby increasing the penetration time.
• This article discloses that glycerol has been used as a humectant with 2,4-D and other herbicides.
• Other glycols disclosed are ethylene and propylene glycol, and polyhdric alcohols in mixtures with free fatty acids and DMSO. Polymeric compounds are reported to be humectants which according to this article includes Carbowax, sucrose, molasses and polypropylenediol.

• silica an organosilicone surfactant, such as Silwet L-77 in tank mixes with commercially purchased Roundup® herbicide at time improves the rainfastness of the resulting formulation of Roundup on some species of weeds.
• Silwet L-77 is antagonistic to Roundup herbicide in such tank mixes with Roundup herbicide when rainfall does not occur after a Roundup composition containing Silwet L-77 (without added humectant) has been applied to many plants, particularly on narrowleaf species.
• Monsanto sells "Pulse” penetrant (which is L-77) for use with Roundup herbicide and discloses on the Pulse label that the addition of Pulse can reduce the rainfree period for Roundup herbicide from 4-6 hours to 2 hours on perennial ryegrass when label recommended rates of Roundup herbicide and Pulse are sprayed on dry foliage.

• a herbicidal method of use of such compositions is also disclosed.
• this published patent application discloses that suitable humectants can be employed to keep a salt of N-phosphonomethylglycine moist over a longer period of time on the foliage of plants, thereby enabling it to be absorbed into the foliage in a greater quantity and at a higher rate than would otherwise be possible.
• herbicide formulations retain a significant degree of activity when plants treated therewith are exposed to rain shortly after application, this being a definition of the degree of "rainfastness.” This is particularly important for water-soluble foliar-applied herbicides, such as glyphosate salts.
