The present invention relates to a herbicidal composition comprising (α) {a compound of the after-mentioned formula (I) or its salt} and (β) at least one compound selected from the group consisting of {after-mentioned compounds (B), (C) and (D)} as active ingredients. Further, it relates to a method to reduce unfavorable effects of (α) {a compound of the after-mentioned formula (I) or its salt} against useful crop plants.
In recent years, so-called selective herbicides having both safety for useful crop plants and herbicidal effects against undesired plants are actively used, but even a highly selective herbicide has phytotoxicity depending upon various conditions such as weather conditions, soil conditions, varieties of the crop plants, and the timing for the application of the herbicide in some cases. To cope with such an unanticipated situation, use of various safener has been studied, but the selection of the safener varies depending upon the type of the herbicide with which the safener is used in combination and depends on trial and error studies. Further, it is more desired to apply a herbicide with broad herbicidal spectrum to crop plants at a dosage as low as possible, thus reducing the load to the ecosystem such as rivers, the soil and the ocean. Heretofore, search for compounds to be novel herbicidally active ingredients has been conducted, but the search is not easy and takes long, and accordingly it has been attempted to combine existing herbicides to develop synergistic herbicidal effects. However, this attempt also depends on trial and error studies in the same manner as above.
WO02/30921 or WO92/14728 discloses a compound of the after-mentioned formula (I), and the latter exemplifies known herbicidal ingredients which may be mixed with the compound of the after-mentioned formula (I) wherein substituent R is a hydrogen atom. In such exemplification, some compounds among the after-mentioned compound group (β) are disclosed. However, they are simply listed as known herbicidal ingredients and not specifically described as specified in the after-mentioned herbicidal composition of the present invention. Further, these publications fail to disclose any technique to reduce unfavorable effects of the after-mentioned compound of the formula (I) or its salt against crop plants.

Patent Document 2: WO92/14728
At present, many herbicidal compositions have been developed and used. However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect. Further, (α) {a compound of the after-mentioned formula (I) or its salt} brings about unfavorable effects against crop plants in some cases depending upon various conditions at the actual application site, and accordingly it is preferred to take steps to reduce possibility of such problems as far as possible, so as to improve usefulness.
The present inventors have conducted extensive studies to achieve the above object and as a result, they have found that a highly useful herbicidal composition can be obtained by using (α) {a compound of the after-mentioned formula (I) or its salt} and (β) at least one compound selected from {after-mentioned compounds (B), (C) and (D)} in combination. In addition, they have further found that a herbicidal composition which reduces unfavorable effects of (α) {a compound of the after-mentioned formula (I) or its salt} against crop plants which may possibly be brought about depending upon various conditions, can be obtained by combination with the after-mentioned compound (D). The present invention has been accomplished based on these discoveries.
Namely, the present invention relates to a herbicidal composition comprising (α): {a compound of the formula (I) or its salt (hereinafter referred to simply as the compound (α)):
wherein R is a hydrogen atom or —COCH2OCH3} and
(β): at least one compound selected from the group consisting of [(B): {at least one sulfonylurea compound selected from (B1.1) bensulfuron-methyl, (B1.2) azimsulfuron, (B1.3) pyrazosulfuron-ethyl, (B1.4) imazosulfuron, (B1.5) ethoxysulfuron and (B1.6) halosulfuron-methyl;
at least one pyrimidinyl salicylic acid compound selected from (B2.1) pyriminobac-methyl and (B2.2) KUH-021;

(C): {a compound of the formula (II), its salt or its ester:
wherein W is a hydrogen atom or a methyl group, X is a chlorine atom or a methyl group, Y is a hydrogen atom or a methyl group, n is 0, 1 or 2, Z is —OH, —SH or —NT1T2, and each of T1 and T2 is a hydrogen atom, an alkyl group or a phenyl group which may be substituted} (hereinafter referred to simply as the compound (C)), and
(D): {(D1.1) 1-(1-methyl-1-phenylethyl)-3-p-tolylurea (common name: daimuron), (D2.1) S-1-methyl-1-phenylethyl piperidine-1-carbothioate (common name: dimepiperate), (D2.2) S-ethyl azepane-1-carbothioate (common name: molinate), (D2.3) O-3-tert-butylphenyl 6-methoxy-2-pyridyl(methyl)thiocarbamate (common name: pyributicarb) and their salts} (hereinafter referred to simply as the compound (D))] (hereinafter referred to simply as the compound (β)) as active ingredients, a method for controlling undesired plants or inhibiting their growth by applying a herbicidally effective amount of such a herbicidal composition, and a method for controlling undesired plants or inhibiting their growth by applying a herbicidally effective amount of the above compound (α) and a herbicidally effective amount of the compound (β).
Further, the present invention relates to a method for reducing unfavorable effects of the compound (α) against crop plants by the compound (D).
The herbicidal composition of the present invention, i.e. the herbicidal composition comprising the compound (α) and the compound (β) as active ingredients, is capable of controlling a wide range of weeds emerging in cropland or non-cropland, and it surprisingly presents a synergistic herbicidal effect i.e. a herbicidal effect higher than the mere addition of the respective herbicidal effects of the active ingredients. With such a herbicidal composition of the present invention, not only it can be applied at a low dose as compared with a case where the respective active ingredients are applied individually, but also the herbicidal spectrum will be enlarged, and further the herbicidal effects will last over a long period of time.
When the herbicidal activity in a case where two active ingredients are combined, is larger than the simple sum of the respective herbicidal activities of the two active ingredients (the expected activity), it is called a synergistic effect. The activity expected by the combination of two active ingredients can be calculated as follows (Colby S. R., “Weed”, vol. 15, p. 20-22, 1967).
E=p+q−(p×q÷100)
where p: growth inhibition rate when treated with x (g/a) of herbicide X,
q: growth inhibition rate when treated with y (g/a) of herbicide Y,
E: growth inhibition rate expected when treated with x (g/a) of herbicide X and y (g/a) of herbicide Y.
Namely, when the actual growth inhibition rate (observed value) is larger than the growth inhibition rate by the above calculation (expected value), the activity by the combination can be regarded as showing a synergistic effect. The herbicidal composition of the present invention shows a synergistic effect when calculated by the above formula.

The herbicidal composition of the present invention is capable of controlling a wide range of weeds emerging in cropland or non-cropland, since not only it can be applied at a low dose as compared with a case where the respective active ingredients are applied individually, but also the herbicidal spectrum will be enlarged, and further the herbicidal effect will last over a long period of time.
