Description

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

[0001]

The present invention relates to a herbicidal composition containing tolpyralate and thiaphenacyl as active ingredients. The present invention also relates to a method for controlling unwanted plants, which includes applying herbicidal effective amounts of tolpyralate and thiaphenacyl to the unwanted plants or to the area where they are growing. The present invention also relates to a mixture containing tolpyralate and thiaphenacyl as active ingredients. The present invention also relates to a combination of tolpyralate and thiaphenacyl as active ingredients.

BACKGROUND OF THE ART

[0002]

Patent Document 1 discloses a herbicidal composition that contains benzoylpyrazole and another herbicidal compound as active ingredients, and Patent Document 2 discloses a herbicidal composition that contains uracil and another herbicidal compound as active ingredients. However, these documents do not specifically describe the combination of tolpyralate and thiaphenacyl proposed in the present invention and its effects.

[0003]

Currently, many herbicidal compositions have been developed and used, however, there are many types of unwanted plants, such as weeds, that are controlled, and, for example, due to the acquisition of resistance to herbicides, it is difficult to control many of the unwanted plants. For example, it is reported that in the USA Amaranthus palmeri S. Watson, white pigweed (Chenopodium album L.), Canadian small-petalled (Conyza canadensis (L.) Cron.), ivy-shaped morning glory (Ipomoea hederacea Jacq.), pitted morning glory (Ipomoea lacunosa L. .), morning glory (Ipomoea purpurea L.), amaranthus tuberculatus (Moq.) J.D. Sauer) and ragweed (Ambrosia elatior L.) have acquired resistance to herbicides and they are noted as difficult to control weeds in cultivation broadleaf crops, fruits and vegetables (Non-Patent Document 1). In addition, although non-patent document 1 does not specifically mention herbicide resistance, it discloses cornflower (Cyperus esculentus L.), kochia scoparia L., black nightshade (Solanum nigrum L.), etc., as weeds, which are difficult to control when growing broad-leaved crops, fruits and vegetables, and additionally hidden Abutilon theophrasti MEDIC., Faber's bristle grass (Setaria faberi Herrm.), millet (Echinochloa crus-galli L.), etc., as common weeds when growing broad-leaved crops, fruits and vegetables.

DISCLOSURE OF INVENTION

TECHNICAL PROBLEM

[0006]

Accordingly, it has been desirable to develop a herbicidal composition having a broader herbicidal spectrum and high activity and therefore capable of controlling a variety of undesirable plants. In addition, in recent years, a technique for reducing the dose of the active ingredient has become desirable to reduce the environmental burden at or around the site to which the herbicide is applied.

THE SOLUTION OF THE PROBLEM

[0007]

The inventors of the present invention have conducted extensive research to solve the above problem and as a result have discovered a combination of herbicidal active ingredients with good suitability. Thus, the present invention relates to a herbicidal composition containing as active ingredients (a) tolpyralate and (b) thiaphenacyl. The present invention also relates to a method for controlling unwanted plants, which includes applying herbicidally effective amounts of (a) tolpyralate and (b) thiaphenacyl to the unwanted plants or to the area where they are growing. The present invention also relates to a mixture containing as active ingredients (a) tolpyralate and (b) thiaphenacyl. The present invention also provides a combination of (a) tolpyralate and (b) thiaphenacyl as active ingredients. As used herein, the herbicidal composition, mixture and combination may sometimes simply be referred to as a herbicidal composition.

USEFUL EFFECTS OF THE INVENTION

[0008]

The herbicidal composition of the present invention is capable of controlling a wide range of unwanted plants growing in non-agricultural fields or agricultural fields, and is capable of controlling unwanted plants that are considered difficult to control. In addition, the herbicidal composition of the present invention is capable of exerting a greater effect than when the respective active ingredients are applied separately. As a result, the dose of (a) tolpyralate and (b) thiaphenacyl can be reduced and therefore the present invention is very useful for practical application.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009]

In fig. Table 1 shows the degree of inhibition of the growth of Canadian small petal on days 19, 27 and 42 after treatment with only tolpyralate (10 g/ha), only thiaphenacyl (50 g/ha) and tolpyralate (10 g/ha) and thiaphenacyl (50 g/ha) in combinations.

DESCRIPTION OF IMPLEMENTATION OPTIONS

[0010]

The herbicidal composition proposed in the present invention contains as active ingredients (a) tolpiralate and (b) thiaphenacyl.

[0011]

(a) The tolpyralate and (b) thiaphenacyl of the present invention may form salts, alkyl esters, hydrates, different crystalline forms, different structural isomers, etc., and these are, of course, all included in the present invention.

[0012]

In the present invention, the mass ratio when mixing (a) tolpyralate with (b) thiaphenacyl usually cannot be determined because it varies depending on various conditions, such as the types of preparations of the active ingredients being mixed, weather conditions and the type and growth stage of the unwanted plants being treated. struggle, but usually it is from 1:0.001 to 1:100, preferably from 1:0.01 to 1:80, more preferably from 1:0.025 to 1:50, even more preferably from 1:0.05 to 1: 30, especially preferably from 1:0.1 to 1:20.

[0013]

In the present invention, the dosages of (a) tolpyralate and (b) thiaphenacyl generally cannot be determined because they vary depending on various conditions, such as the types of preparations of the active ingredients being mixed, weather conditions and the type and growth stage of the unwanted plants being controlled. Dose (a) is usually 0.01 to 300 g/ha, preferably 0.05 to 200 g/ha, more preferably 0.1 to 150 g/ha, even more preferably 0.5 to 100 g/ha ha, especially preferably from 1 to 50 g/ha. Dose (b) is usually 0.01 to 400 g/ha, preferably 0.05 to 300 g/ha, more preferably 0.1 to 200 g/ha, even more preferably 0.5 to 100 g/ha ha, especially preferably from 1 to 100 g/ha.

[0014]

The herbicidal composition of the present invention has excellent herbicidal effect. Application areas range from non-agricultural fields such as forested areas, farm roads, playgrounds and business sites to agricultural fields such as rice fields, crop fields, orchards and mulberry fields. The application method of the herbicidal composition of the present invention may preferably be selected from the group consisting of soil application, foliar application, drench application, and the like, and is particularly suitable for foliar application. In addition, the timing of application may not necessarily be selected from a wide range from post-harvest application to pre-planting application.

EXAMPLE 1

The soil from the upland areas was placed in a pot with an area of 1/1000000 ha and the seeds of Conyza canadensis (L.) Cron. were sown. On the 73rd day after sowing, the SC preparation containing tolpyralate as the active ingredient and the SC preparation containing thiaphenacyl as the active ingredient were diluted with water (in an amount corresponding to 200 l/ha) and 1 vol.% of the excipient (commercial name: Destiny HC, manufactured by Winfield Solutions, LLC.), then foliar treatment of Canadian small petal (diameter: 12 to 15 cm) was carried out with an automatic boom sprayer. On the 21st day after foliar treatment, the growth status of Canadian petal was assessed visually and the degree of growth inhibition (measured value) was determined in accordance with the evaluation criteria (Table 1).

When tolpyralate or thiaphenacyl were used alone, sufficient growth inhibition was not achieved even at day 19 after foliar application. On the other hand, when tolpyralate and thiaphenacyl were used in combination, new leaves were severely discolored and growth was inhibited up to 42 days after foliar treatment at any dose. It has been established that the growth of canada canadensis can be suppressed for a longer period of time than when using tolpyralate or thiaphenacyl alone.
