Description

This application has been filed under 35 USC 371 as a national stage application of PCT/JP 95/01251, filed Jun. 22, 1995.
TECHNICAL FIELD
The present invention relates to a herbicidal composition containing a fluoropropylthiazoline derivative and a certain type of herbicide as active ingredients.
BACKGROUND ART
Many years of research and development of herbicides brought a great variety of chemicals into practical use, and these herbicides have contributed to labor saving in weed control and the improvement in the productivity of farm and garden crops. Even in these days, development of new chemicals having more excellent herbicidal properties is still demanded. As agricultural and horticultural herbicides, chemicals which selectively control the target weeds at low doses without showing phytotoxicity to crop plants are particularly desired. However, no existing chemicals satisfy all these desired conditions.
The compound represented by the following formula (1) in the present invention �hereinafter referred to as compound (1)!, which was disclosed in International Patent Application PCT/JP95/00011, is a herbicide which shows an excellent herbicidal effect on Graminaceous weeds such as wild oat and blackgrass and broad-leaved weeds such as common lambsquater, common chickweed, kedlock and slender amaranth at low doses in foliage treatment and is fairly safe for sugar beet, but does not have much effect on some broad-leaved weeds. ##STR2##
On the other hand, the compound represented by the following formula (2) �hereinafter referred to as compound (2)!, the compound represented by the formula (3) �hereinafter referred to as compound (3)!, the compound represented by the formula (4) �hereinafter referred to as compound (4)!, the compound represented by the formula (5) �hereinafter referred to as compound (5)! and the compound represented by the formula (6) �hereinafter referred to as compound (6)! are already known and in practical use as herbicides for sugar beet, but have a drawback that they don't have much effect on Graminaceous weeds or some broad-leaved weeds. ##STR3##
DISCLOSURE OF THE INVENTION
The present inventors found combined use of compound (1) and at least one compound selected from the group consisting of compound (2), compound (3), compound (4), compound (5) and compound (6) not only compensates for the drawbacks of the individual compounds used in single formulation but also enables reduction in the application dose and simultaneous control of Graminaceous weeds and broad-leaved weeds. The present invention has been accomplished on the basis of this discovery.
The common name of compound (2) in the present invention is phenmedipham, the common name of compound (3) is ethofumesate, the common name of compound (4) is chloridazon, the common name of compound (5) is metamitron, and the common name of compound (6) is triflusulfuron-methyl (test name DPX-66037).
In addition to compound (2), compound (3), compound (4), compound (5) and compound (6), the following compounds may be mentioned as a herbicide which can be used in combination with compound (1). Examples of such formulations will be given later in Formulation Examples 26 to 39.
It is also possible to add one or two of the following compounds to a mixture of compound (1) and at least one compound selected from the group consisting of compound (2), compound (3), compound (4), compound (5) and compound (6).
Desmedipham (common name), cycloate (common name), diallate (common name), lenacil (common name), TCA, pebulate (common name), endothal (common name), EPTC, fluazifop-P-butyl (common name), sethoxydim (common name), haloxyfop-methyl (common name), quizalofop-ethyl (common name), trifluralin (common name), diethatyl-ethyl (common name) and the like may be mentioned. Examples of such formulations will be given later in Formation Examples 40 to 56.
Addition of such a chemical to compound (1) or to a mixture of compound (1) and one of compounds (2) to (6) is expected to lead to, for instance, a broad weeding spectrum, a reduced application dose and persistent herbicidal effect.
In the present invention, compound (1) and one of compounds (2) to (6) are used in an appropriate ratio selected from such a range that the two chemicals do not impair each other's performance.
For example, one of compounds (2) to (6) is used preferably in an amount of from 0.01 to 500 parts by weight, more preferably from 0.1 to 100 parts by weight per 1 part by weight of compound (1).
When the herbicidal composition of the present invention is used as a herbicide, it is usually mixed with a suitable carrier, for instance, a solid carrier such as clay, talc, bentonite, diatomaceous earth or white carbon, or a liquid carrier such as water, an alcohol (such as isopropanol, butanol, benzyl alcohol or furfuryl alcohol), an aromatic hydrocarbon (such as toluene or xylene), an ether (such as an anisole), a ketone (such as cyclohexanone or isophorone), an ester (such as butyl acetate), an acid amide (such as N-methylpyrrolidone) or a halogenated hydrocarbon (such as chlorobenzene). If desired, a surfactant, an emulsifier, a dispersing agent, a penetrating agent, a spreader, a thickener, an antifreezing agent, an anticaking agent or a stabilizer may be added to prepare an optional formulation such as a liquid formulation, an emulsifiable concentrate, a wettable powder, a dry flowable, a flowable, a dust or a granule.
The herbicidal composition of the present invention is fairly safe for sugar beet and effectively controls Graminaceous weeds and broad-leaved weeds, which are harmful to cultivation of sugar beet.
Now, examples of formulations of the herbicidal composition of the present invention will be given below. However, it should be understood that the present invention is by no means restricted to such specific examples.

Now, the following Text Examples are given to demonstrate that the combination of compound (1) with one of compounds (2) to (6) has a more excellent effect than their single formulations anticipate, namely has a synergic effect.





TEST EXAMPLE 1
Plastic box having a length of 33 cm, a width of 33 cm and a depth of 8 cm were filled with sterilized diluvial soil, and slender amaranth was sown at a depth of about 1.5 cm dep in each box. The plant was grown in a greenhouse at a temperature of from 20.degree. to 25.degree. C. for 14 days and then treated with chemicals. Wettable powders of compound (1), compound (2), compound (3) and their mixtures were suspended and diluted with water to predetermined concentrations, and 10 ml of each suspension was uniformly applied to the foliage. The plant was grown in the plastic boxes placed in a greenhouse. 28 Days after the treatment, the aerial parts of slender amaranth were weighed, and the control rates (Eo) were calculated from the following formula. ##EQU1##
Although individual active compounds usually have drawbacks in their herbicidal activities, the herbicidal effect of a mixture of two active compounds can exceed the simple sum of the effects of the individual compounds (the expected control rate). In such a case, it is called synergy. The expected control rate Ec of a specific combination of two herbicides is calculated as follows (Colby S. R., calculation of synergic and antagonistic effects of herbicide combinations, "Weed", vol. 15, pp. 20-22, 1967).
Ec=.alpha.+.beta.-(.alpha..multidot..beta.)/100
.alpha.: The control rate of herbicide A applied at a rate of (a) kg/ha.
.beta.: The control rate of herbicide B applied at a rate of (b) kg/ha.
Ec: The expected control rate of herbicide A applied at a rate of (a) kg/ha and herbicide B applied at a rate of (b) kg/ha.
Namely, when Eo is larger than Ec, the effect of the herbicide combination is considered as synergy.
The results are shown in Table 1 and Table 2. The symbol in the Tables has the following meaning.
A: Slender amaranth

From the results in Table 2, it is evident that mixtures of compound (1) with compound (2) and compound (3) have effects exceeding the expected values and act synergically on slender amaranth.
TEST EXAMPLE 2
Plastic boxes having a length of 33 cm, a width of 33 cm and a depth of 8 cm were filled with sterilized diluvial soil, and tufted knotweed was sown at a depth of about 1.5 cm. The plant was grown in a greenhouse at a temperature of from 20.degree. to 25.degree. C. and then treated with chemicals. Wettable powders of compound (1), compound (4), compound (5) and their mixtures were suspended and diluted with water to predetermined concentrations, and then 10 ml of each suspension was uniformly applied to the foliage. The plant was grown the plastic box is placed in a greenhouse. 28 Days after the application, the aerial parts of tufted knotweed were weighed, and the control rates (Eo) were calculated in the same manner as in Test Example 1. The results are shown in Table 3 and Table 4. The symbol in the Tables has the following meaning.
