Definitions

  • the invention relates broadly to
  • Glyoxylates 12H-dibenzo[d,g] [1,3]dioxocin-6-carboxylic acid and certain derivatives thereof, generally referred to herein as "glyoxylates", and their use as plant growth regulant and/or herbicidal agents and more particularly to their use, usually in combination with appropriate carriers and surfactants, in influencing the growth and development of crops, ornamentals and turf grasses.
  • X and Y are hydrogen or a halogen and R is hydrogen or lower alkyl are disclosed to have utility as hypolipidemic agents for warm blooded animals.
  • pharmaceutically acceptable salts of such acids are disclosed.
  • An improved class of hypolipidemic agents are disclosed by the same inventors in U.S. Patent No. 3,941,173 wherein carboxamides are also contemplated.
  • no utility in the agricultural field is suggested, and on tests of the specific compounds disclosed in U.S. Patent No. 3,553,234 and U.S. Patent No. 3,941,173 no herbicidal activity was found.
  • the present invention is based upon the discovery that a selected group of such compounds possesses unexpected activity when employed as plant growth regulant and/or herbicidal agents at controlled dosages, while other closely related compounds within the genus of U.S. Patent 3,553,234 display no significant agrochemical activity.
  • plant growth regulant means a compound or composition which affects the maturation and metabolism of plants.
  • a plant growth regulant has many effects on plant growth.
  • plant growth regulant active compounds affect plants the same way. For example, they could affect vegetative growth by retarding or stimulating terminal growth, and/or stimulating side branching and could inhibit new growth such as the development of new sprouts of woody plants, the sprouting of tubers and rhizomes and the development of sucker growth.
  • Such regulants could affect flowering plants by eliminating early flowering, by thinning of blossoms or by increasing the number of flowers.
  • Fruit-bearing trees and bushes could be affected by increases in the number, size and quality of the fruit, by producing seedless fruit, by accelerating senescence and fruit ripening. Both flowering and fruit plants could be affected by accelerating plant dormancy and maintaining bud dormancy.
  • a "plant growth regulant" could cause selective postemergent control of weeds by reducing their vigor and competitiveness, and thus prevent their spread and stop normal seeding.
  • plant growth regulants Some specific applications of plant growth regulants include:
  • Plant growth regulant also means the retardation of terminal (i.e. vertical) growth of plants. In grasses and weeds, this regulant activity will retard the grass height and, hence, grass growth. In bushy plants, on the other hand, the resultant retardation of terminal growth by the regulant activity often results in enhancement of lateral growth, an effect desired, e.g. in tomato plants.

  • plant growth regulant or “plant growth regulating effect” refer to the ability of a glyoxylate, when applied to a plant locus, to influence the growth and development of useful crops, ornamentals and turf as for example described by illustration hereinbefore. A variety of effects may be obtained depending upon, among other considerations, the plant in question, the glyoxylate selected and the manner, amount and timing of application.
  • the result obtained by application of a glyoxylate is the desirable promotion, inhibition and/or alteration of a plant's physiological or morphological processes, such as accelerating or retarding leaf, shoot and root growth, reduction in stature, increased branching, tillering, terminal inhibition, inhibition of regrowth after pruning thereby reducing the need for follow-up pruning, increased root growth, delayed budding, increased bud count, yield increases, etc.
  • the glyoxylates of the present invention have been found to be effective growth retardants when applied to turf grasses such as, perennial rye, red and tall fescue and Kentucky bluegrass.
  • a further example of a plant growth regulating effect is the ability of a glyoxylate compound, when timely applied (preferably in the second or third growth stage) to act as a straw shortening agent on wheat, an especially useful effect where high nutrient levels are employed to increase grain yield.
  • herbicide or "herbicidal effect” refers to the application of a glyoxylate compound to kill, or at least substantially inhibit the growth of, an undesired plant.
  • a glyoxylate compound to kill, or at least substantially inhibit the growth of, an undesired plant.
  • one of the glyoxylates to control the growth of weeds, including grassy weeds, in wheat and reduce flowering in bolting weed beets.
  • the glyoxylates have been found to be particularly useful in controlling the growth of the generally hard to control sedges, especially yellow nut sedge, when applied to the soil in which the nut sedge tubers are beginning to germinate.
  • Each of the defined glyoxylate compounds has been found to have a herbicidal and/or plant growth regulating effect.
  • a particular ester or salt form of a glyoxylate will often be chosen for its convenience of handling and application, an example being the choice of the n-butyl ester, which has reduced volatility, over the methyl ester form.
  • volatility is desirable, e.g., for application by fumigation (smoke bombs) in a greenhouse to induce branching of ornamentals
  • compounds such as the nitrile and lower esters (e.g., methyl, ethyl and propyl) which are more volatile, may be preferred.
  • substitution opportunities are particularly limited when placed in the 1, 2, 10 and 11 positions according to the following number system:
  • the glyoxylates will be applied to the plant locus as the active ingredient in a composition also comprising a carrier and a surfactant, that is, a dispersing, emulsifying or wetting agent, although diluents, extenders and other active ingredients having a differing or complementary utility may be present.
  • a surfactant that is, a dispersing, emulsifying or wetting agent, although diluents, extenders and other active ingredients having a differing or complementary utility may be present.
  • the compositions may thus be in the form of finely divided particulate solids, granules, wettable powders, solutions and dispersions.
  • the inert carrier may be solid (e.g., clays, natural or synthetic silicates, talcs) or liquid (e.g., water, alcohols, esters, aromatic hydrocarbons, petroleum fractions).
  • the surface active agents may be anionic, cationic or non-ionic (e.g., salts of lignosulfonic acids, alkyl-aryl sulfonic acids, acetates of alkylamines and condensates of ethylene oxide with fatty alcohols or acids).
  • the compositions may contain thickeners, adhesives, stabilizers, preservatives and other adjuvants known to the art.
  • the glyoxylates may be applied by conventional techniques (e.g., spreading, dusting or spraying or via fumigation smoke bombs in confined areas such as greenhouses) in a variety of forms (e.g., solutions, suspensions, wettable powders or granules).
  • conventional techniques e.g., spreading, dusting or spraying or via fumigation smoke bombs in confined areas such as greenhouses
  • forms e.g., solutions, suspensions, wettable powders or granules.
  • compositions of the present invention generally will contain from 5 to 95 percent by weight of the active glyoxylate compound and will be applied at a rate of from 0.5 to 4 kilograms per hectare, when used as herbicides. While in a plant growth regulating composition the amount of active ingredient may be comparable, the amount employed will vary greatly depending upon the particular glyoxylate chosen and the effect in question, generally ranging from 0.01 gram to 4 kg per hectare. Conveniently, such applications are obtained by spraying a solution containing from 0.1 to 500 ppm active ingredient to run-off, depending on the plant species to be treated.

After 48 hours of total reflux time, the reaction mixture thickens and vigorous stirring is maintained.
  • the condenser is replaced with a distillation head and 200 ml of isopropyl alcohol is distilled off at atmospheric pressure and replaced with 200 ml of H 2 O. This is repeated until the distillation temperature reaches 95-100oC.
  • the reaction mixture becomes much more fluid and eventually a reddish brown homogenous solution is obtained.
  • the reaction mixture is cooled to room temperature. Upon cooling, solids form, therefore it is important to maintain vigorous stirring.
  • the reaction mixture is then made strongly acidic by the careful addition of concentrated HCl (800 ml) over a period of 1-2 hours.

  • the organic solution is then washed with 200 ml of brine, dried over MgSO 4 and concentrated under reduced pressure to afford a thick light reddish-yellow liquid (130 grams).
  • This liquid is then subjected to vacuum distillation, using a Claisen adapter as the distillation head and an oil bath for heating. Care is taken during the course of the distillation to avoid solidification of the product in the distillation condenser.
  • a forerun (11 grams) is collected having a b.p. 70oC to 170oC at 0.25 mm. Pure n-butyl ester, 84.3 grams (62 percent), is then collected from 171oC to 180oC at 0.25 mm as a thick clear liquid which readily solidifies on cooling to afford a white solid: mp 63-66°C (softening at 60oC); greater than 99 percent purity as determined by L.C.

  • the herbicide screening test is designed to identify compounds that exhibit pre-emergence (Pre) and/or post-emergence (Post) herbicidal activity. Plantings of the indicated test species are seeded in separate fiber pans (8" X 10" X 3" deep) containing pasteurized soil. The Post pans are seeded two weeks prior to treatment. The Pre pans are seeded one day prior to application of the test compounds. One Pre and one Post pan is employed for each compound, unless otherwise indicated. Prior to application of the test formulation, the Pre pans are mist watered to stabilize the soil surface.
  • the standard laboratory formulation at the 8 kg/ha treatment rate is prepared by weighing 73.6 mg of the test compound into a 125 ml flask to which is then added 40 ml of acetone followed by 40 ml of 0.1% Ortho X-77 surfactant. If the test compound appears insoluble in the formulation, it is treated for 1-2 minutes with an ultrasonic probe. If still insoluble, the particle size is reduced by grinding to a size sufficient to allow it to pass through the spray nozzle. Following preparation of the test formulations, each is then sprayed equally and completely on the Pre and Post pans employing a handheld spray gun with an air atomizing nozzle. Acetone is employed to rinse the spray gun between application of each formulation.
  • the treated pans are then moved to a growth room, or greenhouse, where they are maintained and appropriately watered for 13 days following treatment. At this time, the pans are then evaluated to determine the percent kill/inhibition/suppression relative to an untreated control.
  • the rating numbers range from 0, indicating no injury, to 100, indicating complete kill or control. Compounds that show 80% control Post and 50% control Pre against any 3 species are considered for further testing. Results are shown in the following Table.

  • the acid form of the glyoxylate prepared in Example 1 was evaluated as a turf growth retardant on four grass species at varying rates as indicated in Table 2.
  • Turf species were planted in 8 by 8 cm fiber pots using steam pasteurized soil, and allowed to grow until well established, i.e., roots extended to the bottom of the fiber pot.
  • the turf was clipped periodically to keep the thatch at a manageable level and fertilizer was applied on a regular basis. Prior to application of the compound to the turf, the grass was cut to one cm.
  • the compound was formulated in 15 X 125 mm disposable test tubes and foliar applications were made in a hood using a DeVilbliss Model EGA-502 hand held sprayer.
  • Example 99 Using the turf species set forth and grown as in Example 99, the effect of the method of application of the compounds of Examples 16 and 2 is evaluated, with results set forth in Table 3. Weight measurements are taken by cutting each turf pot, after two weeks, to a uniform height, combining the clippings from all species and oven drying prior to weighing.
  • Granular application is found to result in the lowest degree of phytotoxicity to the grass species.
  • Wheat testing is done in 13 cm round plastic pots.
  • the wheat is planted in a mixture of 75 percent soil and 25 percent sand which has been steam pasteurized to control indigenous weed seed and pathogens. Seeds are planted and then covered with approximately 1 cm soil/sand mix and placed on fiber matting in the greenhouse. The pots are both mist watered and bottom watered until seedlings emerged. After emergence, only bottom watering is done.
  • the growth stage is recorded, and pots are removed to a spray hood for treatment.
  • the compound to be applied is placed in a 15 by 125 mm test tube and dissolved in 12 ml of acetone and water. The compound is sprayed onto the foliage using a hand held Devilbiss spray gun (Model EGA-502). This sprayer emits an extremely fine spray particle and results in maximum coverage of the foliage. Operating air pressure is 840 gm/cm 2 .
  • Applications are made at four different rates at each of six growth stages. The growth stages are as follows:
  • Acer palmatum Japanese cutleaf maple
  • ATRINALTM a commercial formulation by MAAG of dikegulac
  • Rooted single-stem cuttings of azaleas (Rhododendron sp., cv 'Elsi Lee') are transplanted to artificial potting medium in 4 inch round plastic pots. These cuttings are pinched as they were moved. After growth resumes, these plants are sprayed to run-off using a hand held spray unit. Treatments employ the K salt of Example 15 and dikegulac, a commercial plant growth regulator which is used to induce branching and to prevent regrowth after pruning. Treatments, based on five replicates of each are listed in Table 9.
  • Non-sprayed control plants in which the terminal bud was pinched grew 18.3 cm while non-sprayed non-pinched plants grew 11 cm.
  • pinched control plants sprayed with the solvent increased in height 15 cm and non-pinched, non-sprayed plants grew 8.5 cm.
  • all compounds tested essentially eliminated terminal bud elongation, regardless of concentration of the applied solution. Thus, these compounds appear to have excellent utility when used to reduce vertical growth of this tree species.
