  • Volatile formulations can be used in apparatus and methods for treating crops after storage to preserve same during shipment to warehouses, grocery stores, and the like, especially in small containers such as cardboard boxes, bags and the like.
  • Tubers especially potatoes, are treated with sprout inhibitors during storage ⁇ See U.S. Patent 6,010,728). These techniques involve placing upon the potato a residue of a sprout inhibitor, especially CIPC, as a dormancy enhancer, 1,4 dimethyl naphthalene (1,4 DMN).
  • CIPC chloroisopropyl carbamate
  • aerosol containers filled with 1,4 DMN are placed in trucks to provide an enveloping vapor of DMN during shipment to a store or other destination.
  • Duncan and Beveridge in about 1978 treated potatoes with vapors of 1,4 DMN at high dosage levels.
  • Liquid chemical crop-preservative compositions suitable for sprout inhibition of ware potatoes in a box, bag or other small shipping containers may comprise 1 ,4 DMN (1,4 dimethyl naphthalene), in conjunction with suitable adjuvants, diluents, solvents, surfactants, lubricants, odorants or deodorants, or the like.
  • suitable volatile chemical preservatives capable of effecting a crop-preservative effect by vapors from such chemicals are useful as well.
  • Other types of preservatives may include volatile fungicides, biocides and pesticides and the like.
  • liquid chemical compositions disclosed and claimed herein may preferably be applied in accordance with the invention disclosed in said co-pending application, but also by alternative techniques.
  • 1 ,4 DMN is especially suitable as a dormancy enhancer for potatoes in storage or during shipment.
  • a pure 1 ,4 DMN product known as 1,4 Sight ® is available from 1 ,4 Group of Meridian, Idaho.
  • An aerosol container, 1 ,4 ShipTM, filled with 1 ,4 DMN and a suitable aerosol propellant is also available from 1 ,4 Group for use in railroad cars, trucks, etc. during shipment of potatoes.
  • 1 ,4 DMN maintains or returns potatoes to a state of dormancy, it is by such an effect, an effective sprout inhibitor and reducer of respiration.
  • Such aerosol containers are occasionally not activated by shipping personnel.
  • Ware potatoes are those potatoes intended for immediate consumption as such by consumers in the form of baked potatoes, boiled potatoes or other potato dishes prepared in homes, restaurants and the like. Ware potatoes desirably are in a non-sprouting condition and contain no CIPC. 1 ,4 DMN is a natural product found in freshly harvested potatoes.
  • Pure 1 ,4 DMN is relatively expensive as a chemical, but it is a very effective sprout inhibitor/dormancy enhancer especially when applied to potatoes when first introduced into a storage unit. See U.S. Patent 6,010,728 of Forsythe, et al. It can readily be applied to storage units as an aerosol, which forms a vapor, which is adsorbed by the stored potatoes. In contrast to CIPC, a well-known sprout inhibitor, which is deposited on bulk potatoes in a storage facility as minute solid particles derived from an aerosol.
  • DMN acts as a hormonal agent, prolonging dormancy, which is in contrast to most chemicals approved for potato sprout inhibition.
  • Treatment of storage facilities typically involves such DMN being introduced at a concentration of about 2.0 micrograms per kg of stored potatoes; i.e., providing a theoretical
  • the total quantity of DMN applied at a similar concentration to that applied to storage units would involve a very small amount.
  • a vapor concentration of 2 micrograms/kg for a 50 lb. box of potatoes (about 22 kg) would require about 50 micrograms.
  • a liter (1000 ml) of DMN similar in density to water, weighs about one kilogram, one milliliter therefore equals approximately one gram.
  • the liquid quantity to treat a 50 lb. box would be about
  • a lubricant also may be
  • a diluent or solvent may be useful in conjunction with a compatible lubricant.
  • Lower alkyl naphthalenes such as 1 ,4 DMN and related isomers, are known solvents.
  • the inclusion of a suitable quantity of lubricant in the liquid treatment composition may be advantageous to preclude frictional wear upon moving parts of the injection devices.
  • DMN may include rollers, stamps, ink jet printers and the like. Such techniques may apply significant quantities of a liquid chemical composition, but relatively accurately apply only a small quantity of DMN, the active ingredient, especially when such active ingredient is a small fraction of the total liquid composition.
  • Suitable diluents include lower alcohols, which have been used as solvents for CIPC, e.g., methanol and isopropyl alcohol. Such alcohols are inexpensive compared with DMN and are relatively odorless. Also, given their volatility, similar to that of DMN, by the time such ware potatoes are consumed, any such adsorbed or absorbed alcohol will have evaporated from the skin of the potatoes.
  • Other useful diluents may include ethanol, hexanol, octanol, nonanol, decanol and dodecanol, and the like. Most alcohols have some sprout inhibition characteristics. Various essential oils may also be included because of their volatility and sprout inhibition character.
  • essential oils have a strong persistent odor, e.g., clove oil, which may be undesirable to consumers.
  • Preferable essential oils include limonene, citronellol, citral and orgenol. Diluents, depending upon their type, and/or aroma characteristics may be used in varying amounts.
  • Deodorized DMN compositions such as those disclosed and claimed in U.S. Patent 6,403,526 may be utilized with DMN alone or in combination with suitable diluents and lubricants as descried herein.
  • Any diluents or aroma-inducing or odor-negating liquid chemicals are preferably volatile so that no substantial residue of any chemical remains on a container when it is to be disposed of or recycled.

  • lubricants may include Castor oil, canola oil, olive oil, alkyl oleate and other food grade oils. Oils, which are less likely to turn rancid are preferred. If rancidity is a concern, small amounts of antioxidants such as vitamin E may be included in the oils.
  • DMN is a very effective dormancy enhancer for tubers
  • mixtures of it with volatile essential oils may be very advantageous from an efficacy and economy standpoint.
  • Many essential oils have good tuber sprout inhibiting properties and are less expensive than DMN, especially 1 ,4 DMN which has proven to be the best substituted naphthalene for treating stored potatoes to minimize sprouting and has been in commercial use for about a decade and is the only methyl naphthalene having an EPA registration
  • Certain volatile essential oils which may be used include clove oil,
  • DMN was shown to be effective on sprouting root and tuber crops, including but not limited to, beet, carrot, cassava, dasheen (taro), ginger, ginseng, horseradish, parsnip, pototato, sweet potato, turnip, and yam.
  • DMN was also shown to be effective on sprouting bulb crops, including but not limited to, garlic, leek, onion, and shallot.
  • DMN was also shown to be effective on sprouting ornamentals, such as flowering bulbs.
  • the various 1 ,4 DMN based formulations disclosed herein may be useful in the preservation of crops such as berries, especially raspberries, blackberries, and strawberries during shipment to market.
  • Treatments of berries with predetermined dosages of 1 ,4 DMN have generally aided in maintenance of hydration, color and general health. Strawberries and other crops as well are often contaminated with a fungus or mold even after washing. Such fungi or mold often blooms after the strawberries reach a consumer, thereby shortening their useful life. Treatment of such crops with the disclosed 1 ,4 DMN formulation tends to kill or diminish the presence of such fungi and molds.
  • 1 ,4 DMN is a principal component of the novel formulations of the instant invention. It is an active chemical, providing sprout inhibition and hydration for potatoes. Besides diluents, etc. other active ingredients may be included in the formulations. For example, 2-nonanone has been identified as a mold retardant for fresh berries (see U.S. Patent 5,334,619). This chemical is relatively volatile so that it could be compatively included in a 1 ,4 formulation used to treat benies, for example, either in a closed room or in containers during shipment to market.
  • Other active chemicals in the unique compositions of the instant invention may include higher alcohols, such as C 6 -C] 0 , aliphatic alcohols, having a volatility similar to that of 1 ,4 DMN.
  • Higher alcohols such as nonanol were shown by Burton, namely, a trimethyl hexanol, to be very effective sprout desiccators for potatoes, i.e., "burner" of nascent sprouts.
  • the C 6 -C io alcohols have a volatility similar to that of 1 ,4 DMN so a mixture thereof may compatibly be effectively fogged or applied to a container as a liquid with the vapors thereof providing an efficacious result.
  • Especially useful are such alcohols as 1 -nonanol, 1 -hexanol, 1 -octanol and 1 -decanol, the latter being solid at room temperatures, but highly soluble in 1 ,4 DMN.
  • Other useful active chemicals may include lower alkyl esters of C 6 -C io aliphatic alcohols, such as methyl, ethyl or propyl esters of 1 -nonanol or 1 -hexanol. Mixtures of these with 1 ,4 DMN have also provided surprisingly good results in achieving sprout inhibition of potatoes, especially ware potatoes, while maintaining a desirable degree of hydration.
  • the above-identified volatile chemicals may also be used separately from 1 ,4 DMN, when as separate active ingredients or in admixtures of such chemicals with solvents, diluents and the like.
  • the unique formulations described herein are uniquely composed to provide a volatile active ingredient upon a packaged commodity, it may be useful to incorporate a dye or pigment in such formulation to enable affixation of a logo or message on said package.
  • the volatile active ingredients described herein such as 1,4 DMN and volatile alcohols are effective solvents, thus, the inclusion of soluble dyes therein provide an ink which has crop-preserving properties.
  • Such inks may be applied to a crop or produce-containing package by ink jet printers, for example, to inscribe text or logos thereon.
  • Various ink formulations which may be incorporated in the unique compositions of the instant invention include those described in U.S. Patent 7,393,400 and 4,168,662.
  • volatile liquid formulations described and claimed herein may be used to treat a wide variety of crops and produce during the filling of various types of packages, boxes, cartons, etc. in preparation for distribution to grocers.
