Description
The present invention relates to an improved process for the control of weeds, and specifically thistles.
It has been found that 2,4-dichloro-6-(o-chloroanilino)-ji-triazine while generally non-phytotoxic, has a high specific action against thistles, e.g. creeping thistle (Cirsium arvense).
Accordingly, the present invention is for a process for the control of thistles in crops which comprises applying to a thistle infested crop the compound 2,4-dichloro-6-(o-chloroanilino)- -triazine.
The 2,4-dichloro-6-(o-chloroanilino)-ji-triazine may be applied to the thistles and the crop in any suitable formulation. 2,4-dichloro-6-(o-chloroanilino)-s-triazine is substantially insoluble in water, and may be formulated in any of the ways commonly adopted for the formulation of v/ater insoluble materials. Thus, for example the 2,4-dichlorc—5-(o-chloroanilino)- -triazine may be incorporated with solid inert media comprising powdered or divided solid materials, for example clays such as china clay, sands, talc, mica, fertilizers and the like; such products either comprising dust or larger particle size materials.
It is preferred however to mix the 2,4-dichloro-6-(o-chloroanilino)-s[-triazine with a wetting agent, with or without the incorporation of powdered or divided solid materials as referred to above, so that a wettable product is obtained which is capable of use as such or as a suspension or dispersion in water.
If desired the 2,4-dichloro-6-(o-chloroanilino)-jj-triazine may be incorporated with an organic solvent, which may be for example a high boiling hydrocarbon, suitably together v/ith a wetting or dispersing agent so as to form an emulsifiable liquid concentrate which may be dispersed in water for spraying purposes .
The wetting agents used may comprise anionic compounds such as for example, soaps, fatty sulphate esters such as dodecyl sodium sulphate, fatty aromatic sulphonates such as alkylbenzene sulphonates or butyl naphthalene sulphate, mora complex fatty sulphonates such as the amide condensation product of oleic acid and N-methyl taurine or the sodium salt, of dioctyl sulphosuccinic acid. The wetting agents may also comprise non-ionic wetting agents such ae for example condensation products of fatty acids, fatty alcohols or fatty substituted phenols with ethylene oxide, or fatty esters and ethers of sugars or polyhydric alcohols, or the products obtained from the latter by condensation with ethylene oxide, or the products known as block copolymers of ethylene oxide and propylene oxide. The v/etting agents may also comprise cationic agents such as for example cetyl trimethylammonium bromide and the like.
The 2,4-dichloro-6-(o-chloroanilino)-s>-triazine is highly specific for thistles, and particularly creeping thistles (Cirsium arvense , and has virtually no effect on other plant species. Thus, this compound may be used for the selective control of thistle in any crop, without adverse effect on the crop.
Crops which nay be mentioned include cereals, soft fruit, such as strawberry and raspberry, vegetables such as cabbage and cauliflower, root crops such a3 carrot and potato, flowers, grass etc.
The treatment of crops for the control of thistles, in accordance with the present invention, may be combined. Thus the 2 4-dichloro-3-(o-chloroanilino)-s-triazine ma be used in association v/ith other selective herbicides (for example MCPA or 2,4.D). to extend the spectrum of selective activity, or with other type3 of pesticides such as insecticides, fungicides or bactericides.
The following examples are given to illustrate the present invention.
Example 1 A plot of strawberries heavily infested with creeping thistle, Cirsium arvense was sprayed with an aqueous suspension of a 50% wettable powder of 2,4-dichloro-3-(o-chloroanilino)-ji-triazine at a rate equivalent to 4 pounds of 2,4-dichloro-G-(o-chloro-anilino)-j3-triazine in 200 gallons per acre. After three days, a large number of the thistles were found to be badly damaged with the leaves and stems dark grey-brown and necrotic. The strawberry plants were unaffected by this treatment.
Example 2 A strip of winter v/heat 2 yards x 15 yards, containing more than 100 thistle shoots v/ere sprayed with an aqueous suspension of a wettable powder of 2,4-dichloro-6-(o-chloroanilino)- -triazine at a rate equivalent to 2 pounds of active ingredient per acre.
After two days, all thistles were found to be severely scorched and after two weeks all the thistle top growth was dead and no new shoots had arisen from roots below the soil. The v/heat was unaffected by this treatment.
Example 3 A newly sown grass ley infested with thistles was sprayed v/ith 2,4-dichlorc—6-(o-chloroonilino)- -triazine at rates equivalent to 2, 1, ¾ and g pound per acre. After four days the number of thistle plants under each treatment which was severely scorched was counted. Results are tabulated below.
The grass was unaffected by this treatment.
The present invention also includes the killing of thistles with 2,4-dichloro-6-(o-chloroanilino)-s-triazine whether or not associated with crops; such use may be related to total weed destruction, as for example on railway line3. For such use, the compound may be used alone, v/here thistles represent the main weed problem, or mixed with other herbicides, e.g. phenoxyaliphatic acid, chloro-benzoic acid, triazine and urea herbicides, whore a mixed weed population requires to be destroyed.
