Description

(54) HERBICIDAL COMBINATIONS (71) We, LILLY INDUSTRIES LIMITED, a British company of Henrietta House, Henrietta Place, London, W.1., do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to novel herbicidal combinations, to herbicidal formulations containing the novel combinations and to methods of controlling weeds in areas of sugar cane growth with said combinations and formulations or by treatment of said weeds separately with the components of said com- bination.
According to the present invention there is provided a herbicidal composition which com- prises, as active ingredients, a thiadiazolyl urea of formula Q:
wherein R is trifluoromethyl, t - butyl or ethylsulphonyl; and 2 - chloro - 4 - ethylamino - 6 - isopropylamino - 1,3,5 - triazine.
The thiadiazolyl ureas of formula {I) are known compounds which may, for example, be prepared by processes as described in U.K.
Patent Specification No. 1,266,172. The com- pound 2 - chloro - 4 - ethylamino - 6 - iso propylarnino - 1,3,5 - triazine is also a known compound and has been given the non-proprietary name "Atrazine".
At this point it should be noted that the compound of formula (I) where R is t - butyl, i.e. 1- (5 - tert - butyl - 1,3,4 - thiadiazol 2 - yl) - 1,3 - dimethylurea, is the compound of choice for use in the combinations, formulations and methods of the present invention.
The ratio of the amount of the thiadiazolyl urea to the 2 - chloro - 4 - ethylamino - 6 isopropylamino - 1,3,5 - triazine is not critical; however, it is preferred to combine the com- pounds at weight ratios in the range of from 1:10 to 10:1, more preferably from 1:5 to 5:1 and most preferably from 1:3 to 3:1.
As indicated above, it has surprisingly been found that the combinations of the invention are particularly effective in the control of weeds in land where sugar cane is growing. The thiadiazolyl urea and the triazine are preferably applied simultaneously in the form ot a com- bination but in some cases sequential application of the components of the combination may be effected. Such sequential application should be effected within a short period of time.
Whether sequential or simultaneous application is carried out, from 0.5 to 2.5, preferably 0.75 to 1.5, kg/hectare of the urea and from 0.5 to 5, preferably from 1 to 2, kg/hectare of the triazine are generally applied to the land to be treated.
The compositions of the invention will normally be utilised in the form of a herbicidal formulation, the active ingredients being associated with one or more non-phytotoxic carrivers. Such formulations, as well as methods of preparing the compositions and formulations comprising admixing the ingredients, form further aspects of the invention.
One formulation according to the present invention which may be mentioned is an aqueous suspension which can be sprayed onto the area to be treated. Such a formulation may be prepared by mixing the active ingredients in a spray tank just prior to use or more preferably the two active ingredients are formulated together in the desired proportions and this formulation may then merely be diluted prior to use. Such an aqueous formulation will generally comprise from 0.005 to 2.5%, preferably from 0.1 to 1%, by weight of the urea and from 0.005 to 5, preferably from 0.1 to 2% by weight of the triazine.
As stated above, the diluted formulations of the present invention may be produced by mixing the active ingredients just prior to use or by diluting a ready-prepared co-formulation of the two active ingredients. In the former case, the active ingredients will usually be in the form of concentrate compositions so formulated as to be capable of ready dispersion in water. Generally, any appropriate concentrate compositions may be used and will contain from about 1 to 90% by weight of the individual active ingredients.
In the case where the active ingredients are formulated together in concentrate compositions, the latter are novel and form a part of this invention. Such concentrates will normally contain from 5 to 90% total weight of the active ingredients.
The concentrate compositions of the present invention normally comprise the active ingredients in the above stated amounts, one or more non-phytotoxic carriers and optionally one or more surfactants, thickening agents, antifreezing agents and preservatives. The concentrates may be solids usually known as wettable powders, or liquids which may be aqueous suspensions.
Wettable powders comprise an intimate mixture of the active ingredients, one or more non-phytotoxic carriers and appropriate surfactants. The carrier may be chosen from the attapulgite clays, the montmorillonite clays, The diatomaceous earths, kaolins, micas, talcs and purified silicates. Effective surfactants may be found among the sulfonated lignins, the naphthalene sulfonates and condensed naphthalene sulfonates, the alkyl succinates, the alkylbenzene sulfonates, the alkyl sulfates and nonionic surfactants such as ethylene oxide adducts of phenol. Wettable powder formulations falling within the scope of the invention typically contain: % by weight Thiadiazolyl urea 10160 Atrazine 20--60 Surfactant(s) 1-7 Dispersing agent 1-7 Anti-caking agent 0-10 Solid Carrier to 100 The total amount of active ingredients, i.e.
urea and atrazine, should not exceed 90%.
Aqueous suspensions comprise the active ingredients suspended in water together with any desired surfactants, thickening agents, antifreezing agents or preservatives. Suitable surfactants may be chosen from those mentioned above in connection with wettable powders.
Thickening agents, if used, are normally chosen from appropriate cellulose materials and natural gums whilst glycols will generally be used when an antifreezing agent is required.
Preservatives may be chosen from a wide range of materials such as the various paraben antibacterials, phenol, o-chlorocresol, phenyl mercuric nitrate and formaldehyde. Aqueous suspensions falling within the scope of the invention typically contain: % weight/ volume: Thiadiazoylyl urea 5-30 Atrazine 10-30 Surfactant(s) 1-5 Thickening agent 0-2 Antifreezing agent 0-10 Preservative 0-2 Water (Carrier) to 100 Alternatively, it may be desired to apply the novel combination of the invention in the form of a granular formulation. Such a formulation typically comprises the active ingredients dispersed on a granular carrier such as coarsely ground clay. The particle size of granules usually ranges from about 0.1 to about 3 mm.
The usual formulation process for granules comprises dissolving the compound in an inexpensive solvent and applying the solution to the carrier in an appropriate solids mixer.
Somewhat less economically, the compound may be dispersed in a dough composed of damp clay or other carrier, which is then dried and coarsely ground to produce the desired granular product.
Although of much less importance, the coformulations of the present invention may also take the form of emulsifiable concentrates.
The following non-limitative examples will further illustrate the invention. In each case the urea which was utilised was 1 - (5 - tert butyl - 1,3,4 - thiadiazol - 2 - yl) - ],3 -di- methylurea; however, it will be appreciated that this urea may be replaced by its 5 - trifluoromethyl and 5 - ethylsulphonyl analogues without detriment EXAMPLE 1 This is an example of a wettable powder according to the invention: % by weight Urea 30 Atrazine 45 Sodium lauryl sulphate 5 Sodium lignin sulfonate 3 Silica 8 China clay to 100 The active ingredients were milled and then blended with the other ingredients in conventional mixing equipment. The blend was then milled in a fluid energy mill to a size range of from 1 to 10 microns and finally the mixture reblended and deaerated prior to being packaged.
Similarly, the following wettable powders were prepared: EXAMPLE 2 % by weight Urea 10 Atrazine 20 Sodium lauryl sulfate 4 Sodium lignin sulfonate 2 Kaolin to 100 EXAMPLE 3 % by weight Urea 30 Atrazine 30 Sodium alkyl succinate 6 Mica 5 China clay to 100 EXAMPLE 4 % by weight Urea 30 Atrazine 55 Sodium lignin sulfonate 4 Sodium succinate 2 Silica 2 China clay to 100 EXAMPLE 5 /O by weight Urea 30 Atrazine 40 Sodium lauryl sulfate 7 Silica 8 China clay to 100 EXAMPLE 6 The following is an example of an aqueous suspension according to the invention.
