Abstract
The effect of certain agricultural chemicals, viz. fungicides, herbicides, insecticides, nematicides and plant-growth regulators, is improved by co-administration of them with one or more additives which modify the uptake of the chemical by modifying physico-chemical properties of the leaf or which alter the physical relationship between the agricultural chemical and the leaf surface such that the uptake of the agricultural chemical is altered beneficially including by holding the agricultural chemical in a layer on the leaf surface during a period when it is not needed by the plant (as during the winter months) and then releasing it as a result of increased temperature and/ or light degradation in the spring. The invention provides compositions containing one or more of the said agricultural chemicals and one or more of the said additives, and methods of improving the harvest of a given crop by applying it to one or more of the said agricultural chemicals and one or more of the said additives simultaneously or within up to about 15 days of one another. The compositions may be made up with purgatives e.g. phenolpthalein, or emetics such as apomorphine and ipecahuana although the additives themselves have the ability to reduce the mammalian toxicity of agricultural chemicals with which they are mixed.
Description
ENGINEERING IMPROVED CHEMICAL PERFORMANCE IN
PLANTS
Modification of Chemical Uptake
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. 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 (wetting agents) 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. When the application is simultaneous, the agricultural chemical and 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".
The use of 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. 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.
Although it is beneficial for a surfactant (wetting agent) to be used with 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. Thus 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. On the return of Spring when the plant may beneficially use a growth regulator and/or the action of a fungicide against fungal disease becomes of importance, then with increasing air temperatures and/or increasing solar radiation, the coating agent breaks down to free the trapped agricultural chemical. At this point in the utilisation of the agricultural chemical by the crop the presence of the surfactant (wetting agent) contained also within the coating is especially beneficial.
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.
Although within the patent literature there are reports of encapsulated agricultural chemicals that slowly release their contents, the use of a coating agent to preserve an agricultural chemical in position during what is effectively a dormant period and its subsequent release with the return of growing conditions, is a novel and hitherto unexpected feature of such coating processes. The following experimental data show effects produced by certain compositions and methods in accordance with the present invention and compare such effects with those of the prior art.
