Description

The present invention relates to a phytotoxicity reducing agent. More specifically, the present invention relates to a phytotoxicity reducing agent containing a bactericidal compound as an active ingredient, and a herbicidal composition containing the phytotoxicity reducing agent and a herbicidal compound.

The use of herbicides is indispensable in crop cultivation in order to secure an appropriate yield of the crop and to realize efficient cultivation of the crop. Currently, the herbicides used are endowed with selectivity for the crop, and in principle do not cause damage to the crop except for the plants to be controlled.

However, the crop selectivity of the herbicide is not always sufficient, and depending on the conditions of use of the herbicide, the herbicide causes growth disorders, growth suppression, growth suppression, appearance of brown spots, and cracking suppression in the crop. , Yellowing, leaf withering, withering, wilting, whitening, twisting, browning, inhibition of root growth, etc. may cause known or unknown undesired phytotoxicity.

So far, in order to avoid the phytotoxicity, herbicides having different actions have been used in combination, and a compound (Safener) having a phytotoxicity-reducing effect has been used in combination with a herbicide (Patent Documents 1 to 1). 4. Non-patent document 1).

The compounds selected from the group consisting of hydroxyisoxazole, picalbutrazox, siazophamide, kasugamycin, chlorotalonil, benomyl, thiophanate methyl, isoprothiolane and amysulfrom are known bactericidal compounds, and each compound is described in Table 1 below. As shown in, it is described in the relevant patent document.

In the past, it has been reported that 3-hydroxy-5-isoxazole (hereinafter referred to as "hydroxyisoxazole"), which is a bactericidal compound, has an effect of reducing herbicide damage in rice (Non-Patent Document 2).

Further, it is known that isothiazole carboxamides, which are resistance inducers, have a herbicide phytotoxicity-reducing effect by treating seeds and applying them to a nursery box (Patent Documents 16 to 18).

Further, isoprothiolan having bactericidal activity and insecticidal activity is known to have a phytotoxicity reducing effect on the herbicide tefryltrione (Patent Document 19).

Pesticide Outlook December 2001, pp. 10-15 Study on the growth-regulating effect of 3-hydroxy-5-isoxazole on crops 3rd report on flood damage of rice seedlings and phytotoxicity reduction effect of herbicides Masami Ogawa and Yasuo Ota Journal of the Japanese Crop Society, Vol. 43, pp. 531-537 (1974)

However, these conventional phytotoxicity reducing agents contain a compound having herbicidal activity or a compound having no biological activity (herbicide activity, bactericidal activity, insecticidal activity, etc.) as an active ingredient, and the target is specific. By limiting to cultivated plants, the phytotoxicity caused by the herbicide was reduced only for a specific herbicide. Therefore, the existing phytotoxicity reducing agents have not been universally usable for various cultivated crops (Patent Documents 1 to 4 and Non-Patent Document 1).

Specifically, regarding hydroxyisoxazole, which is a bactericidal compound, herbicides whose phytotoxicity-reducing effect has been confirmed are simethrin and DCPA (propanil; Dimethyl 2,3,5,6-terrachlorophenene-1,4-). It is a mainly photosynthesis-inhibiting herbicide such as dicarboxylate), MCC (swep) and MCP (2-methyl-4-chlorophenoxyacetate ethyl). Therefore, no knowledge has been obtained regarding the phytotoxicity-reducing effect of recently developed herbicides.

Regarding isoprothiolane, although it is known to reduce the phytotoxicity of herbicides against tefryltrione, no knowledge has been obtained regarding the phytotoxicity-reducing effect of other herbicides.

Furthermore, the herbicidal phytotoxicity-reducing effect of bactericidal compounds having bactericidal activity such as picarbutrazox, siazofamide, kasugamycin, chlorotalonil, benomyl, thiophanate-methyl, isoprothiolan and amysulfrom has not been clarified at present.

The subject of the present invention is that it has a biological activity other than the herbicidal effect, shows a phytotoxicity-reducing effect on various herbicides showing different actions, and has a phytotoxicity-reducing effect on cultivated plants superior to existing herbicides. At the same time, it is necessary to find a new phytotoxicity-reducing agent having a wide range of use, which is not limited to cultivated plants.

As a result of various studies to solve the above problems, the present inventors have found that a predetermined bactericidal compound exhibits a herbicide phytotoxicity reducing effect. That is, they have found that a phytotoxicity reducing agent containing a predetermined bactericidal compound as an active ingredient and a herbicidal composition containing the phytotoxicity reducing agent and a herbicidal compound have a good phytotoxicity reducing effect, and completed the present invention.

<Test Example 3>
Hydroxyisoxazole solution (B1) was diluted (500 times) to a concentration of 600 ppm, and then irrigated with seedlings (rice varieties: from Sagabi) grown for 21 days (500 ml / equivalent amount of nursery box). ..

Three seedlings treated with chemicals and transplanted seedlings without chemical treatment were transplanted into a paddy field (inside Agricultural Chemistry Research Institute, Mitsui Chemicals Agro Co., Ltd., Yasu City, Shiga Prefecture). Five days after the transplantation, 20 kg / ha of oxadichromephone 0.8% and tefryltrione 3% granules was treated while maintaining the water depth at 5 cm. In addition, another container was treated with pyrimisulfan 0.67% granules in an amount equivalent to 20 kg / ha. As a control, a complete herbicide plot was set up in which only weeds were removed in order to eliminate the effects of weeds on paddy rice.
Thirty days after the herbicide treatment, plant height, number of stems, and sampling of plants were investigated.
The dry weight was measured by cutting the above-ground part and the root part and drying at 100 ° C. for 1 hour and 80 ° C. for 2 days.

Compared to the complete herbicide plot, oxadichromefone 0.8%, tefryltrione 3% granule double treatment plot, pyrimisulfan 0.67% granule double treatment plot, plant height, number of stems, above-ground dry matter weight, root Chemical damage was confirmed in the dry matter weight. Regarding the groups where phytotoxicity was confirmed, the number of stems, the weight of dry matter above the ground, and the weight of dry matter at the roots increased in the hydroxyisoxazole solution-treated group compared to the hydroxyisoxazole solution-untreated group, and the effect of reducing phytotoxicity was achieved. It was confirmed to have.

According to the present invention, as compared with existing phytotoxicity mitigating agents, phytotoxicity mitigating agents that are universally usable and good for various cultivated crops and phytotoxicity mitigating agents containing the phytotoxicity mitigating agents and herbicides are alleviated. A herbicidal composition can be obtained.

This application claims priority on the basis of Japanese application Japanese Patent Application No. 2018-030986 filed on February 23, 2018 and incorporates all of its disclosures herein.
