Description

CHLOROTOLURON HERBICIDAL MIXTURES
Field of the Invention:
The present invention relates to a herbicidal mixture. More particularly, the present invention relates to a herbicidal mixture comprising an effective amount of chlorotoluron and at least one further co-herbicidal compound and if desired, at least a safener useful for controlling the weeds and grasses.
Background of the Invention:
A persistent issue in agriculture is how to protect crops from weeds and other vegetation that hinder crop growth and negatively affect crop quality and output. Researchers in the field of synthetic chemistry have developed a wide range of chemicals and chemical formulations that are useful in the control of such unwelcome growth to aid in the fight against this issue. There are numerous different kinds of chemical herbicides that have been disclosed in the literatures, and many of them are used commercially.
The types of one or more herbicides used, their application rates, composition, the undesirable hazardous plants to be controlled in each case, climatic and soil conditions, etc., all have a significant impact on the effectiveness of herbicides. Among other things, persistency or the rate of herbicide degradation are other criteria. It may also be necessary to consider how an active ingredient affects the way dangerous plants respond to it over time or in a particular geographic area. Such changes appear as an apparent decrease in activity, and higher herbicide application rates can only partially make up for them.
There is practically no one active ingredient that can have all the needed features for various requirements of this vast number of potential influencing elements, especially with regard to dangerous plant species and climate zones. Additionally, it is always the goal to use as little herbicide treatment as feasible to obtain the desired result. In general, a lower application rate minimises the amount of formulation auxiliaries needed while simultaneously reducing the load of active components needed for the desired purpose. These elements assist in lowering the cost of the herbicide treatment while also enhancing its environmental sustainability.
Chlortoluron, or chlorotoluron, is commonly known as a phenylurea herbicide. It is described in U.S. Patent 2,655,445 by E. I. du Pont de Nemours and Company. It is a contact and residual photosynthesis inhibitor used to control broadleaf and annual grass weeds in cereal crops. Chemically, chlorotoluron is 3-(3-chloro-4-methylphenyl)-l,l-dimethylurea and has the following structure:

Active agent mixtures are described in the literature. However, the control over the weeds does not always satisfy the needs of agricultural practice. Additionally, the efficacy of the control provided by these mixtures is not always satisfactory, or it can create additional toxicological and/or environmental effects. Random herbicidal formulations and mixtures do not exert a satisfactory controlling effect in most of the cases, and therefore, there is an urgent need for the development of new herbicidal mixtures having satisfactory controlling effects with more than one active ingredient.
It is an object of the present invention to provide mixtures and formulations of judiciously selected active ingredients which have improved activity against harmful weeds. It is an object of the present invention to provide mixtures and formulations of an effective amount of chlorotoluron and at least one further co-herbicidal compound and if desired, at least a safener useful for controlling the weeds and grasses in crops of the cultivated plants.
Summary of the Invention:
It is an endeavour of the present invention to find mixtures comprising chlorotoluron and at least one additional co-herbicide and if desired, at least a safener that increases weed control. These improvements in the form of a synergistic efficacy among active ingredients, whether being applied simultaneously, that is jointly or separately, or in succession. Consequently, weeds can be controlled more effectively than is possible with just the individual compounds. Improvements can also overcome at least one of the challenges in the prior art, for instance, by lowering the dosage rate or by enhancing the spectrum of activity or by combining knock-down activity with prolonged control or by simplifying the management of resistance.
Considering the above, it is an object of the present invention to provide mixtures of active ingredients that improve control of weeds. an object of the present invention to provide a synergistic herbicidal mixture comprising: a) an effective amount of Chloro toluron; b) an effective amount of at least one herbicidal compound selected from the group comprising:

The following representative examples illustrate the practice of the present invention in some of its embodiments but should not be construed as limiting the scope of the invention. Other embodiments will be apparent to one skilled in the art from consideration of the specification and examples. EXAMPLES:
A synergistic effect exists whenever the action of an active ingredient combination is greater than the sum of the actions of the individual components.
In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S. R. in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” published in the journal Weeds, 1967, vol. 15, p. 20-22.
Colby’s formula:
The action expected for a given combination of two active components can be calculated as follows:
E = X + Y - XY/100 in which E represents the expected effect, e.g. percentage of pest control, for the combination of the active ingredients at defined doses (for example equal to x and y respectively), X is the effect, e.g. percentage of pest control, observed for compound (I) at a defined dose (equal to x), Y is the effect, e.g. percentage of pest control, observed for compound (II) at a defined dose (equal to y).
The action expected for a given combination of three active components can be calculated as follows:
E = (X + Y + Z) - (XY + XZ + YZ)/100 + XYZ/10000 in which E represents the expected effect, e.g. percentage of pest control, for the combination of the active ingredients at defined doses (for example equal to x, y and z respectively), X is the effect, e.g. percentage of pest control, observed for compound (I) at a defined dose (equal to x), Y is the effect, e.g. percentage of pest control, observed for compound (II) at a defined dose (equal to y) and Z is the effect, e.g. percentage of pest control, observed for compound (III) at a defined dose (equal to z).
Here, efficacy or percent inhibition is determined in %. 0% means efficacy that corresponds to the control, i.e., as if no treatment had been applied. Whereas a percent inhibition of 100% means that complete control is observed. When the percent control observed for the combination is greater than E, there is a synergistic effect. When the percent control observed for the combination is equal to E, there is an additive effect and wherein the percent control observed for the combination is lower than E, there is an antagonistic effect.
