The present invention relates to a novel compound and a paddy herbicide containing the compound as an active ingredient. For more details However, R represents a cis-type alkenyl group having 4 or 5 carbon atoms; The present invention relates to a rice field herbicide characterized by containing as an active ingredient at least one compound of the present invention (referred to as a compound of the present invention). The purpose of the present invention is to obtain this compound industrially and to provide a paddy herbicide that is extremely effective in rice cultivation compared to related compounds. Many haloacetanilide derivatives having herbicidal activity are already known, and among them, N-alkoxymethyl derivatives are also known in the literature. For example, Special Publication No. 48-4524, No. 48-37820,
US Pat. No. 3,442,945 and US Pat. No. 3,547,620 are known. In particular, in the aforementioned Special Publication No. 48-37820, N.
Test examples of pre-emergence phytotoxic activity are described for more than 100 types of haloacetanilide derivatives, including -alkenoxymethyl derivatives. Among these derivatives, the compounds actually commercially available are 2',6'-diethyl-N-methoxymethyl-2-chloroacetanilide and 2',6'-diethyl-N-butoxymethyl-2-chloroacetanilide. In both cases, R in the above general formula corresponds to an alkyl group, and the former is C 1 and the latter is C 4 . Among the haloacetanilide derivatives mentioned above, 2',6'-diethyl-N-alkoxymethyl-2-chloroacetanilide is thought to have particularly excellent efficacy as a herbicide, but in reality, the same N-alkoxy Even if it is a methyl substituted product, N-
Methoxymethyl-substituted products (R=C 1 ) are mainly used as field herbicides for corn, soybeans, cotton, sugar cane, etc., whereas N-butoxymethyl-substituted products (R=C 4 ) are used for paddy rice and wheat. It is used as a herbicide for radish, and the difference in alkyl groups has an extremely large effect on plants. In fact, according to Table 1 (test table) of Japanese Patent Publication No. 48-37820, N-methoxymethyl substituted products and N-ethoxymethyl substituted products inhibit the growth of rice, whereas N-propoxymethyl substituted products and N-propoxymethyl substituted products Results show that -butoxymethyl substitutions do not inhibit growth (see Compound Nos. 3, 8, 14 and 21). Furthermore, even if the number of carbon atoms in R is the same, whether it is saturated or unsaturated has a large effect; for example, while N-propoxymethyl substituted products do not inhibit the growth of rice,
N-propenyloxymethyl substituted products and N-propynyloxymethyl substituted products have been shown to inhibit growth (Table 1 above, compound numbers 9, 11, and
21). Therefore, according to the knowledge of such prior art,
Among related compounds, compounds in which R has 3 or more carbon atoms and a saturated alkoxy group are effective as paddy herbicides; conversely, in the case of an alkenyloxy group, R has 3 or more carbon atoms and a saturated alkoxy group. It can be seen that it has a growth inhibiting effect on rice. However, as a result of intensive investigation of the properties of these related compounds from the standpoint of their impact on rice, which is required for paddy field herbicides, and their herbicidal properties against grasshoppers, a typical harmful weed, we found that carbon In the case of alkenyloxy groups with 4 to 5 atoms, there is less growth inhibition on rice, and among stereoisomers, compounds with trans-alkenyloxy groups have a lower level of growth inhibition than commercially available compounds with butoxy groups. However, in the case of compounds with cis-alkenyloxy groups, the trans-isomer as well as the commercially available products have a herbicidal effect under paddy field conditions, and are harmful to paddy rice (particularly at high temperatures). ) was found to have a significant improvement effect in terms of fish toxicity. In other words, the compound of the present invention exhibits a strong weed effect against annual and perennial weeds, including the noxious weed, especially when applied to the water surface before the germination of weeds in rice cultivation. At any stage, regardless of the temperature,
It was confirmed that it has a selective herbicidal effect with almost no impact, and is also highly safe for fish. The compounds of the present invention include (1) 2',6'-diethyl-N-[(2-cis-butenoxy)methyl]-2-chloroacetanilide (2) 2',6'-diethyl-N-[( 2-cis-pentenoxy)methyl]-2-chloroacetanilide (3) 2',6'-diethyl-N-[(3-cis-pentenoxy)methyl]-2-chloroacetanilide (4) 2',6'- Diethyl-N-[(1-methyl-2-
cis-butenoxy)methyl]-2-chloroacetanilide. Among them, compounds (1) and (2) are prized. The compounds of the present invention are all characterized by being in the cis form, and therefore are preferably as pure as possible, but as long as they do not essentially impair the effects of the present invention, they may be used as by-products. may contain a trans isomer. However, as the amount of trans isomer increases, the effect of the present invention gradually decreases, so the cis ratio is usually set to 70% or more, preferably 90%.
The above is appropriate. Further, it is essential that the compound of the present invention has 4 to 5 carbon atoms, and compounds having 6 or more carbon atoms are not preferred because their herbicidal activity is extremely poor. Compounds of the invention can be prepared in a variety of ways. Preferably, it can be produced by reacting 2',6'-diethyl-N-chloromethyl-2-chloroacetanilide and cis-alkenol in the presence or absence of an acid binder. All of these raw materials are known substances. The former can be easily obtained by reacting 2,6-diethylaniline with formalin or a formaldehyde low polymer to form an azomethine compound, and then reacting this with chloroacetyl chloride. The latter can also be obtained by partially hydrogenating an alkynol in the presence of a Lindlar catalyst or the like. As another method, first, 2,6-diethylaniline and cis-alkenyl halomethyl ether are reacted to obtain N-(cis-alkenoxy)methyl-2,6-diethylaniline, and then this and chloroacetyl It can also be produced by reacting N-chloroacetyl-2,6-diethylaniline with cis-alkenyl halomethyl ether in the presence of an acid binder. By appropriately combining two or more compounds of the present invention, it is also possible to provide a mixed herbicide that is effective against many grass species. EXAMPLES Next, the present invention will be explained with reference to Examples, but the present invention is not limited to these Examples.

[Table] Test Example 2 Soil treatment test against paddy field weeds A 1/5000 are Wagner pot was filled with paddy soil, and four paddy rice seedlings (variety: Nipponbare) at the two-leaf stage (plant height approximately 10 cm) were transplanted per pot. The soil containing a large amount of seeds of field weeds and major paddy weeds is placed in the surface layer 2.
uniformly inoculated within 3 cm, then submerged in water to 3 cm, and when the wildflowers have grown around the one-leaf stage, dilute the emulsion of the compound of the present invention prepared according to Formulation Example 3 with a predetermined amount of water. It was evenly distributed and stored at an average temperature of 28°C. 25 days after spraying, the herbicidal effect and chemical damage to paddy rice were investigated. The results are shown in Table 2. Evaluation of efficacy and chemical damage to paddy rice was performed in the following six stages. 5: Weed killing rate in the untreated area 80% or more (Rice damage rate in the untreated area) 4: Weed killing rate in the untreated area 60-79% (Rice damage rate in the untreated area) 3: Killing rate in the untreated area Grass rate 40-59% (Rice damage rate compared to untreated area) 2: Weed killing rate 20-39% compared to untreated area (Rice damage rate compared to untreated area) 1: Weed killing rate 20% or less (no treatment) Rice damage rate in treated area) 0: Completely the same as in untreated area
