Abstract
A novel formulation which comprises a thiadiazolyl urea of formula (I) : (I) wherein R is trifluoromethyl, t-butyl or ethylsulphonyl, 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine and a non-phytotoxic carrier which formulation is particularly useful in treating weeds growing in areas of sugar cane.
Description
The present fnvf-nlion relates to novel herbicidal combinations, to herbicidal formulations containing the novel combine tions and to method.-s of controlling weeds in areas of sugar cane growth with co::bh a; ί.,· ., and formulations or by treatment of said weeds separately with the co-mpnaonts of said combination.
According to the present invention there is provided a herbicidal ccticoaition which comprises, as active ingredients, a thiadiazolyl urea of formula (I;:
K
wherein R. is trifluoromethyl, _t-butyl or ethyl sulphonyl;
and 2-chloro-4-ethylamino-6-isopropylarnino-l,3,5-triazine.
The thiadiazolyl ureas of formula (I) are known compounds which may for example, be prepared by processes as described in
Patent Specification
No. 33830. The compound 2-chloro-4-ethylamlno-6-isopropylamino-l,3,5triazine is also a known compound and has been given tha non-proprietary name Atrazine.
At this point it should he noted that the compound of formula (T.J where R is ji-butyl, i.e. l-(5-tert-butyl-l,3,4-thiadiazol-2-yl)-l,3-di:aethylurea, 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-4ethylamino-6-isopropylamino-l,3,5-triazine is not critical; however, it is preferred to combine the compounds at weight ratios in the range of from 1:10 to 10:1, more preferably frem 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
- 2 44S47 of tlie invention ate particularly effective in the control of weeds in land where sugar cane is growing, 'i’he tliladiazolyl urea and the Iriazim· are preler.ibly applied simultaneously in the form of a combination 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 carpositions of the invention will normally be utilised in the form of a herbicidal formulation, the active ingredients being associated with one or more ncai-phytotoxic carriers. 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 OJ3O5 to 2.57., preferably from 0.1 to 17., by weight of the urea and from 0.005 to 5, preferably from 0.1 to 27. 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.
- 3 Generally, any appropriate concentrate compositions may be used and will contain from about 1 to 90% by weight of the individual active ingredient.·:.
In the case where the active ingredients arc formulated together in concentrate compositions, the latter are novel and form a part of this invention. Such concentrates will normally contain from 5 to 907, 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-phytouoxt. carriers and optionally one or more surfactants, thickening agents, anti10 freezing agents and preservatives. The concentrates may he 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 appreciate 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 :
7, by weights
Thiadiazolyl urea 10 - 60 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 907..

Aqueous suspensions comprise the active ingrcdienl .·· suspended tn 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, oychlorocresol, phenyl mercuric nitrate and formaldehyde.

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 co-formulations of the present invention may also take the form of emulsifiable concentrates.
invention. In each case the urea which was utilised was 1-(5-tert-b;it> tl,3,4-thiadiazol-2-yl)-l,3-dimethylurea; however, it will he appreciated that this urea may be replaced by its 5-trifluorometnyl and 5-ethylsulphonyl analogues without detriment.
