Abstract

[Problem] The present invention provides a herbicide composition which can effectively control the growth of a plant that is not desirable for useful plants, is highly safe for useful plants, and can exhibit a high effect at a low dose. [Solution] A herbicide composition characterized by containing, as active ingredients, [a component (A)] selected from the group consisting of a triazine derivative represented by formula [X] (wherein R represents a lower alkyl group having 1 to 6 carbon atoms; and X represents a halogen atom) and a salt of the triazine derivative and [a component (B)] as mentioned in the description.

Description

Herbicidal composition

The present invention relates to a novel herbicidal composition comprising a combination of herbicidal active ingredients suitable for the selective control of weeds in useful plant cultivation.

The present invention also relates to a method for controlling the growth of weeds in the cultivation of useful plants and the use of the novel herbicidal composition therefor.

So far, various herbicides have been developed and contributed to agricultural productivity and labor saving. However, since some herbicides have been used for many years, the number of difficult-to-control weeds to which these herbicides do not work is increasing, the herbicidal spectrum is wide, and the herbicides effective against these difficult-to-control weeds The appearance of is desired. In addition, in order to solve the problem of environmental pollution caused by conventional herbicides, development of herbicides that are highly active and effective at low dosages is also desired. Furthermore, in order to cope with the non-uniform generation of weeds over a long period of time, it is excellent in residual effect and effective even when treated over a wide range of time from the occurrence of weeds to the growing season. The emergence of a broad herbicide is also desired. In addition, in the use of conventional herbicides, weather conditions such as temperature, wind and light, soil conditions such as soil properties and soil organic matter content, cultivation management conditions such as shallow transplantation depth and deep water management, uneven distribution of herbicides and It is known that phytotoxicity may occur in crops due to various factors such as overdose and other chemical application conditions. Even under these conditions, herbicides that are highly safe and do not worry about phytotoxicity in crops. Is also desired.

Specifically, for example, Patent Documents 1 to 4 and Non-Patent Documents 1 to 4 describe many compounds exhibiting herbicidal action. In addition, the microbial pesticide MTB-951 (Tasmart) described in Non-Patent Document 3 is a phytopathogenic imperfect bacterium, Drechslera as monoceras, and is known to exhibit a herbicidal action particularly on the fly. However, these herbicides alone may not provide a wide spectrum as desired, a weed growth control effect over a long period of time, and a sufficient effect for protecting useful plants.

WO2009 / 016841 JP 62-190178 A EP 365484 WO2011 / 071187

The present invention has been made in view of the disadvantages of the prior art as described above, and can effectively control the growth of undesirable plants relative to useful plants, and has high safety against useful plants. In addition, the main object was to provide a herbicidal composition that exhibits a high effect at a low dosage.

As a result of intensive studies to solve the above problems, the present inventors mixed a component selected from the group consisting of a specific triazine derivative and a salt thereof with a component selected from known herbicidal compounds and the like. In addition, it has been found that by using in combination, each herbicidal effect can be obtained not only additively, but also a synergistic herbicidal effect can be expressed, or phytotoxicity can be reduced synergistically. As a result, the herbicidal composition of the present invention can control many kinds of undesirable plants (weeds) generated in field crops, paddy fields, horticulture, turf, etc. over a long period of time, and for useful plants. It was found to have high safety. Further, the herbicidal composition of the present invention can control most of the weeds, particularly those that occur in useful plants, both before and after development, and hardly harms useful plants. As a result, the present invention was completed.

Specifically, two or more kinds of drugs consisting of [Component A] selected from the group consisting of the triazine derivative represented by the formula [I] and salts thereof and [Component B] shown below are mixed or used in combination. By doing so, the herbicidal spectrum is expanded as compared with the range of herbicidal application of each of [Component A] and [Component B], and at the same time, the herbicidal effect is achieved at an early stage and the effect is sustained. In addition to exerting sufficient effects at a lower dose than the amount used in Japan, safety against corn, rice, wheat, barley, grain sorghum, soybeans, cotton, sugar beet, sugarcane, turf, fruit trees, etc. is ensured once. It was found that the treatment exhibited a sufficient herbicidal effect.

That is, the present invention is characterized by having the following gist.

(1) [Component A] selected from the group consisting of triazine derivatives represented by the formula [X] described below and salts thereof, and [Component B] described below as active ingredients A herbicidal composition characterized by that.

<Test Example 22> Herbicidal effect on morning glory during corn growing season treatment in field cropping field, and safety evaluation test for genetically modified maize with herbicide glyphosate tolerance and Lepidoptera pest resistance We evaluated the herbicidal effects of Atrazine alone and mixtures, and the safety of herbicide glyphosate tolerance and Lepidoptera pest resistance genetically modified maize. After plowing, corn was seeded at a depth of about 3 cm, and morning glory was sown on the surface. After sowing, the field was managed according to customary practices. After growing the corn until the plant height is 30 to 35 cm and the morning glory is at the 4th leaf stage, the water of the triazine derivative represented by the above formula [I] prepared according to Example 1 is plotted on a 2 mx 1.5 m plot. A predetermined amount of a Japanese medicine and atrazine liquid (AAtrex 4L <registered trademark>) was diluted with water and sprayed. On the 40th day after the treatment, the herbicidal effect against morning glory and the phytotoxicity against corn were visually evaluated. The index evaluation was 0 (no activity) to 100 (complete death). The results are shown in Table 63. The dose is shown as the amount of active ingredient per hectare.

 

The combination of the triazine derivative represented by the above formula [I] and atrazine (Atrazine, AATrex 4L <registered trademark>) has a synergistic herbicidal effect against morning glory, while high safety against corn It was the same as when the single agent was treated.

The herbicidal composition of the present invention is at least one selected from [Component A] selected from the group consisting of the triazine derivative represented by the formula [X] as an active ingredient and a salt thereof, and the above [Component B]. In combination with two herbicides, or plant growth regulators or safeners, not only can each herbicidal effect be obtained additively, but also a synergistic herbicidal effect can be achieved or It has been shown to have a broad herbicidal spectrum because it is mitigated and effective for many grass species. In addition, it has a wider drug treatment time range than existing herbicides, suppresses the generation of weeds over a long period of time, and safety has been confirmed for both [Component A] and [Component B]. Therefore, it does not cause phytotoxicity to useful plants, and can contribute to labor saving in cultivation and increased production of crops.
