Description

[0001] HERBICIDAL COMPOSITION [0002]

The present invention relates to a novel herbicidal composition comprising a combination of herbicidally active ingredients suitable for the selective control of weeds on useful plants.

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

So far, various herbicides have been developed, contributing to agricultural productivity and labor saving (labor saving). However, since any kind of herbicide has been used for many years, there is an increase in heating weeds that these herbicides do not listen to, and it is demanded that the herbicidal spectrum is broad and the herbicide effective also for these heating herbicides is desired. In order to solve the environmental pollution problem caused by the conventional herbicide, development of a herbicide which is highly active and effective at a low dose has also been desired. In addition, in order to cope with inconsistent occurrence of weeds over a long period of time, the emergence of a herbicide having an excellent residual effect and a wide treatment effective width even after treatment for a wide range of time from before the generation of weeds to the growing stage is also desired. In addition, in the conventional herbicide use, it is preferable to use the herbicide composition in such a manner that the temperature, weather conditions such as wind and light, soil conditions such as soil (soil) and soil organic matter content, cultivation management conditions such as depth of shallow transplantation, It is known that there is a possibility that a crop may be vulnerable to various factors such as conditions of application of a chemical such as excessive dispersing. Under these conditions, however, a herbicide having high safety without fear of chemical attack is also desired.

Specifically, for example, non-patent documents 1 to 5 disclose compounds showing a large herbicidal action. In addition, the microbial pesticide MTB-951 (Tac smart) described in the non-patent document 6 is a plant pathogenic incomplete Drechslera monoceras, and it is known that the microbial pesticide MTB-951 However, there is a case in which a broad spectrum as desired by these herbicides alone, an effect of controlling the growth of weeds over a long period of time, and a sufficient effect for protecting useful plants may not be obtained.

DISCLOSURE OF THE INVENTION The present inventors have intensively studied in order to solve the above-mentioned problems. As a result, they have found that by using a combination of a component selected from the group consisting of specific oxopyrazine derivatives and salts thereof and a component selected from known herbicidal compounds, It was found that not only is it obtained merely as additive but also a synergistic herbicidal effect is manifested and synergistic is weakly reduced. Thus, the herbicidal composition of the present invention can control various kinds of undesirable plants (weeds) which occur in the field of aquaculture, field farming, gardening, lawn, etc. over a long period of time, I found out. Further, it is clarified that the herbicidal composition of the present invention can prevent occurrence of most of the weeds, especially, useful plants, both before germination and after germination, giving little harm to useful plants, Finished.

Concretely, the combination of [Component A] selected from the group consisting of oxopyrazine derivatives represented by the formula [X] and salts thereof and two or more agents comprising the following Component [B] And [Component B], the herbicidal spectrum is expanded and the herbicidal effect is achieved early, and the effect is sustained, and the effect of the herbicidal effect is exhibited at a lower level than that of each of the herbicides In addition, it has been found that the safety of rice, wheat, barley, corn, sorghum, sorghum, soybean, cotton, sugar beet, grass and fruit juice is secured and a sufficient herbicidal effect is obtained by one treatment.

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