Definitions

  • the present invention concerns the field of agriculture.
  • the present invention relates to the field of weed control.
  • the present in- vention relates to a herbicidal composition for plants, and a method of controlling weeds.
  • the present invention concerns the field of food processing. More specifically, the present invention relates to a novel method of inhib- iting or delaying sprouting of tubers in storage, and a new use of a composition for inhibiting or delaying sprouting of tubers.
  • Crops refer to plants that are harvested by man for food or used for some other purposes, such as clothing, fuel, paper, building material and medicines . Hence, it is desirable to control the growth of certain plants. In particular, it is of the greatest economical and technical interest to control the growth of weeds in the context of crop production and gardening. Weeds compete with the cultured crops for limited re- sources, such as nutrients, water and light. As a result, the crop yield and/or quality is decreased substantially. Conventional methods of controlling weeds can be mechanical, such as with a harrow or a cultivator, physical, such as with fire or hot water, and/or chemical, such as with herbicides.
  • Herbicides may, according to the properties of the active ingredient, be classified as either selective or non-selective. Selective herbicides eliminate some members of a plant population with little or no harm to other plants, whereas non-selective herbicides destroy all vegetation in the treated area. Herbicides may also be further classified by method of application, such as pre-emergence (application to soil before plant emergence) or post-emergence (application to plant foliage) . The mobility of post-emergence herbicides in the treated plant is broadly classified into two types: contact (non- mobile) or translocated (mobile, i.e. killing plants by systemic action) .
  • Glyphosate N-phosphonomethylglycine
  • Glyphosate is a translocated, post-emergent non-selective herbicide. It is known to act on various enzyme systems, interfering with the formation of amino acids and other endogenous chemicals in treated plants. However, many agronomically important weed species require application of relatively high amounts of glyphosate for effective control . High amounts of glyphosate can lead to undesirable increased selection pressure. Accordingly, glyphosate tolerance is a recognized problem in the field. Moreover, even the seemingly biodegradable glyphosate has been found in ground water. It is also known to use aqueous solutions of acetic acid in high concentrations for controlling weeds.
  • said composition is capable of main- taining a pH of less than about 5 at the plant surface.
  • said carrier substance is a polysaccharide or a derivative thereof, preferably of bacterial or plant origin. It is particularly preferred that said polysac- charide is selected from the group consisting of starches, locust bean gum, guar gum, and xanthan gum. In the most preferred embodiment of the method according to the invention, said polysaccharide is starch.
  • said composition is an aqueous solution or an aqueous vapour.
  • said composition is made from a concentrate or a wettable powder.
  • the present invention also provides a herbicidal composition as defined in the method (s) above.
  • weed and weeds refer widely to any undesirable plant growth, at any stage of a plant's life, from seed through any stage of a plant's development. Thus, a certain plant may or may not be a weed depending on the particular location and/or time point.
  • a surface area of the plant, or weed is contacted with a composition contain- ing a volatile pH-lowering compound and a carrier substance for the pH-lowering compound.
  • the composition according to the invention is a herbicide.
  • herbicide refers to any chemical agent, either organic or inorganic, capable of killing a plant and/or destroying, inhibiting or retarding plant growth, especially of weeds or other undesirable vegetation.
  • herbicidal refers to anything possessing this property, including chemical agents as well as methods. It is envisioned that killing of a treated plant may be accomplished through a local lowering of the pH at the plant surface and the surrounding area/volume . Even though the exact mechanism of the inhibition is not known, it may be speculated that the pH-lowering effect has to be below the plant epidermis.
  • the coating will provide a local environment resembling a gas phase containing the volatile pH-lowering compound.
  • the coating is on the one hand considerably slowing down the gas diffusion of the volatile pH-lowering compound to the surrounding atmosphere, on the other hand driving the gas diffusion of the same compound in the direction into the plant .
  • volatile pH-lowering compounds can diffuse in vaporized condition through the epidermis and reach the inside. This diffusion is independent of the osmotic pressure and will continue until the gas pres- sures are equal on both sides of the epidermis.
  • Polysaccharides are preferably selected from plant polysaccharides and bacterial polysaccharides, such as starches and guar gum, locust bean gum, and xanthan gum.
  • Preferred polysaccharides contain more than 10 monosaccharide units, preferably more than 20 monosaccharide units, more preferably more than 50 monosaccharide units.
  • Compositions according to the invention may be applied to the weeds in any conventional way, including pre-e ergence (application to soil before plant emergence) or post-emergence (application to plant foliage) . It is particularly preferred to employ post-emergent application, i.e. application to plant foliage or any plant parts situated above the ground. However post-emergent application is within the scope of the invention, it is not favourable when it is raining.
  • treatment of plants with the method according to the present invention effectively kills them using substantially lower amounts of the pH-lowering compound compared to when using previously known compositions.
  • this may mean acid concentrations lower than 50%, particularly lower than 24%, more particularly lower than 12%, by weight.
  • prout-inhibiting refers in general to anything that inhibits, suppresses, prevents, arrests or slows down the growth of any new or young growth, i.e. shoots, buds, sprouts, and the like.
  • prout-inhibiting compound refers to any compound possessing this property.
  • Weak acids are particularly preferred as pH-lowering compounds, since they provide mild treating conditions.
  • the tubers are exposed to an environment capable of maintaining a pH of less than about 5 at the tuber surface.
  • the pH is maintained below 2,5, preferably below 2.
  • the environment will not maintain the pH below 1.
  • lowering of the pH at the tuber surface is preferably effected by the use of volatile pH-lowering compounds, such as inorganic or organic acids, buffers, or gases, which in contact with water will generate an acidic environment, e.g. C0 2 , S0 2 , S0 3 or nitrous gases.
  • the sprout-inhibiting composition according to the invention may contain a carrier substance, or matrix.
  • the composition may contain a suitable buffer.
  • the sprout-inhibiting composition according to the present invention optionally contains conventional additives, such as colouring agents, complexing agents, preservatives, plasticisers, detergents, softeners, etc. It is also possible to include anti-microbial agents and/or anti-fungal agents in the composition. It is preferred that the sprout-inhibiting composition is an aqueous solution of acetic acid. Sprout- inhibiting compositions according to the invention may be applied to the tubers in any conventional way, including spraying and exposing the tubers to a gaseous atmosphere thereof .
  • the sprout-inhibiting composition according to the invention is preferably used for the treatment of potatoes in storage. After a dormant period of 1-3 months after harvesting, potatoes are inclined to sprout even in cold storage. The sprouting starts with cell divisions below the "eyes", resulting in enzymatic breakdown of the potato starch with formation of reducing sugars. The mechanism initiating the sprouting is largely unknown. Once a sprout has developed, the treatment according to the present invention will not stop the further development of the sprout . Surprisingly, treatment of potatoes with the method according to the present invention effectively stops the sprouting of potatoes for prolonged periods of time. Inhibition of sprouting can be maintained for at least up to 6 months using the present invention.
  • Aqueous solutions of 1.5% (w/v) guar gum containing various concentrations (1-6% (w/v) ) of formic acid and 0.07% of a neutral detergent are prepared.
  • aqueous solutions of formic acid in various concentrations and 0.07% of a neutral detergent are prepared.
  • the solutions are sprinkled on the leaves of the following plant types: dandelion ⁇ Taraxacum vulgare) , goosefoot [ Chenopodium album) , quackgrass [Agropyron repens) , and red clover ( Trifolium pratense) , which are grown at 18°C. The plants are observed 4, 8, 24, and 48 hours following the administration of the solutions.
  • the solutions containing guar gum are considerably more effective in killing the treated plants than the solutions with corresponding acid concentrations lacking guar gum.
