Definitions

  • This invention relates to agricultural chemicals, which term is used herein to mean fungicides, herbicides, insecticides, nematicides and plant growth regulators, and to methods of using them and compositions containing them.
  • the present invention is concerned with altering the performance of such chemicals.
  • Conventional approach to this involves altering the chemical structure to a greater or lesser degree without altering the class or basic chemical type to which the compound belongs, and/or altering the physico-chemical properties of the formulation containing the chemical, e.g. by the addition of chemicals to stick the agricultural chemical to the target organism or to improve the rainfastness of the agricultural chemical.
  • the literature (including patents) is full of examples of how the conventional approach may be carried out, in particular it is known that addition of a wetting agent (surfactant/surface active agent) can enhance the effect of many agricultural chemicals when it is used at rates which lower the surface tension of the spray solution and enable it to spread over leaf surfaces (particularly where these are waxy) with better effectiveness.
  • This invention is based on the discovery that the efficiency of agricultural chemicals can be markedly improved by the use of wetting agents/surfactants at levels far higher than are requiredto reduce surface tension as hereinbefore described.
  • wetting agents/surfactants At high levels (see Appendix I) such compounds may physically modify the structure of the outer walls of plant cells and leaf surfaces and hence physically modify the structure of a plant leaf such that an agricultural chemical may penetrate it better.
  • Suitable surfactants include but are not limited to those defined in Appendix I (page 10). Where this is done then it has been found beneficial to make a further addition of a coating agent as hereinafter defined in Appendix II (page 12). Alternatively such a coating agent may be used beneficially without a surfactant (wetting agent).
  • This invention provides an agricultural formulation comprising an agricultural chemical as hereinbefore described together with a wetting agent (surfactant) and/or a coating agent as hereinafter described. Such formulations may be in concentrate form, needing addition of, for example, water to make them ready for use.
  • This invention also provides a method of applying an agricultural chemical to a target plant, in which a surfactant (wetting agent) and/or coating agent as hereinafter described is also applied either simultaneously with the agricultural chemical or not more than fifteen days (preferably 10 days) before or after.
  • a surfactant wetting agent
  • the surfactant (wetting agent) and/or coating agent may be supplied in a single formulation or may be mixed in situ in a spray or other chemical-applying apparatus.
  • the wetting agents (surfactants) and/or coating agents used in the formulations and methods of the present invention include but are not limited to those listed in Appendix I wetting agents (surfactants) and Appendix II (coating agents). Such chemicals for use in combination with an agricultural chemical are herein referred to as "Additives”.
  • compositions in accordance with the present invention can enhance the effectiveness of chlormequat (B-chloroethyl trimethylammonium chloride or CCC) . They may also be beneficially used with other plant growth regulators including auxins, gibberellins, ethephon and with mixtures of these.
  • CCC chlormequat
  • the use of high level of surfactants (wetting agents) and/or coating agents as described in this invention have a very general property on the uptake of' agricultural chemicals by plant leaves, such that the activity of a wide range of agricultural chemicals may be beneficially enhanced. In the case of surfactants (wetting agents) by a greater amount than would be expected from their use as a method of reducing surface tension alone especially at temperatures below 10oC.
  • a further aspect of this invention is the use of the substances acting as surfactants (wetting agents) forming this invention to produce a further enhancement of activity when used in conjunction with a coating agent as described in Appendix II.
  • the coating agents used in the formulation and methods of the present invention include, but are not limited to, those polymeric coating agents listed with examples in Appendix II (page 12). Two or more such coating agents in the same or different classes may be used together.
  • a surfactant wetting agent
  • a coating agent as described in Appendix II of this invention
  • such coating agents may be used alone to hold an agricultural chemical onto the leaf of a crop plant during a period when there is no growth and/or necessity for the chemical.
  • An example of such a period would be during the months of December and January in the U.K. where there is little plant growth and fungal diseases are not developing.
  • a growth regulator as hereinbefore described and/or a fungicide may be applied in combination with a coating agent as defined hereinafter in Appendix II or the said coating agent may be applied to the plant within fifteen days of the application of the agricultural chemical.
  • Additives as defined in Appendix I (page 10) and Appendix II (page 12) can act as purgative agents and thus reduce the mammalian toxicity of an agricultural chemical with which they are formulated or with which a formulation containing these additives are mixed in the spray tank or before adding to the spray tank. This decrease in mammalian toxicity may be further enhanced by the addition of known purgatives and/or emetics including phenolphthalein, castor oil, ipecachuana and apomorphine.
  • Concentrations are expressed as a % in the final spray solution applied to the plants.
  • Additives are defined as in the numbered examples on page 5.
  • Example 1 + Example 6 have been added, with respect to their ability to shorten the stems of wheat.
  • the application rate is equivalent to 1.6 kg per hectare of chlorocholine chloride applied in 225 litres of water to Maris
  • Example 1 + Example 6 have been added, with respect to their ability to shorten the stems of wheat.
  • Chlormequat 46 94.4 0.7
  • the application rate was 1.6 kg per hectare of chlorocholine chloride applied in 225 litres of water per hectare to Maris Huntsman wheat in late November (during the early tillering period). Results are expressed as an average of 250 measurements.
  • Example 1 + Example 6 have been added, with respect to their ability to strengthen the stems of barley plants .
  • Example 2 + Example 7 have been added, with respect to their abilities to destroy an old sward.
  • Example 7 9 The application rate was 1.1 kg paraquat per hectare in 400 litres of water.
  • the application rate is equivalent to 0.5 kg of glyphosate per hectare applied in 225 litres of water .
  • Suitable surfactants surface active agents or wetting agents, include but are not limited to:
  • Suitable coating agents include but are not limited to the following:
  • Acrylic polymers and copolymers e.g; Plyacrylic acid
  • Hydrocarbon Resins e.g: Petroleum Resins
  • Rubbers e.g: Natural Rubber Polyurethane Butyl Rubber Nitrile Rubber Polychloroprene Rubber/oil Emuline
  • Thermosetting Polymers e.g: Melamine formaldehyde copolymer
  • Vinyl Polymers and Copolymers e.g: Polyvinyl Acetate
  • These coating agents are applied in from 2 - 10 gallons of water per acre using aerial application or controlled droplet application and from 10 - 500 gallons per acre using conventional ground spray equipment.
  • the application rate is from 100 ml - 25 litres of the coating agent per sprayed acre of crop.

Abstract

L'effet de certains produits chimiques agricoles par exemple les fongicides, les herbicides, les insecticides, les nematicides et les regulateurs de la croissance des plantes, est ameliore en les administrant en association avec un ou plusieurs additifs qui modifient la capacite d'absorption du produit chimique en modifiant les proprietes physico-chimiques de la feuille ou qui modifient la relation physique entre le produit chimique agricole et la surface de la feuille de telle sorte que l'absorption du produit chimique agricole est modifiee avantageusement y compris en placant une couche contenant le produit chimique agricole sur la surface d'une feuille pendant une periode durant laquelle la plante n'en n'a pas besoin (par exemple pendant les mois d'hiver) et en l'enlevant apres augmentation de la temperature et/ou degradation de la lumiere pendant le printemps. L'invention fournit des compositions contenant un ou plusieurs de ces produits chimiques agricoles et un ou plusieurs de ces additifs, et des methodes d'amelioration de la moisson d'une recolte donnee en appliquant un ou plusieurs desdits produits chimiques agricoles et un ou plusieurs desdits additifs simultanement ou a l'un apres l'autre a un intervalle de quinze jours environ. Les compositions peuvent comprendre des purgatifs p. ex. de la phenol-phthaleine, ou des emetiques tels que de l'apomorphine et ipecahiana bien que les additifs eux-memes aient la capacite de reduire la toxicite vis a vis des mammiferes des produits chimiques agricoles avec lesquels ils sont melanges.
