专利摘要:
A herbicidal composition containing as an active ingredient the compound of the formula wherein Ro represents a hydrogen atom or a lower alkyl group, and R1, R2 and R3 each represent a hydrogen or halogen atom, or a lower alkyl, lower alkoxy or lower alkenyloxy group, which is especially useful for application to aquatic rice paddies, and novel compounds of formula (I) wherein Ro, R1, R2 and R3 have the same meanings as defined above, provided that R1, R2 and R3 do not represent hydrogen atom at the same time.

专利说明:

the purpose of enhancing the herbicidal activity, it contains as an active substance a phenyl acetate-nilide derivative of the general formula
/ 3
(oVc-C - T4; cps
where R is hydrogen or C, gC (-alkyl;
3
R is hydrogen, chlorine, bromine, fluorine, C, C-alkyl, C, -Cj-anKOKCH or allyloxy; R is hydrogen, chlorine, methyl, ethyl
or methoxy;
xylene is used as a solvent, and polyoxyethyl alkyl aryl ether as a surfactant at a mass ratio of 30:60: jlO, respectively.
The invention relates to hickshackles for controlling weeds and undesirable vegetation, namely, herbicidal compositions for killing weeds in rice crops. Herbicidal compositions recommended for controlling weeds during rice cultivation are known, for example, the herbicidal composition based on molinata, i.e. N-hexamethylene-8-ethylthiocarbamate 1.
However, this herbicide is used in relatively high doses of the active substance, which often causes significant damage to rice plants. In addition, it is used only by embedding in the soil.
Herbicides recommended for rice cultivation containing c. as active substances annpida carboxylic acids. Such herbicides include, for example, substituted meta-trifluoro methylphenipucetic acid anilides 2.
However, in optimal doses, they are not sufficiently effective for some types of weeds grown in rice crops.
The purpose of the invention is to increase the herbicidal activity of the composition based on feil-acetanilide derivatives.
This goal is achieved by using the following as a herbal composition.
A wettable powder containing the active substance is a phenylacetanilide derivative of the general formula
R is hydrogen or C, -C-alksh1; R is hydrogen, chlorine, bromine, fluorine, C, -C4-alkyl, C-C-alkoxy or allyloxy; R ® ° DOR ° D chlorine, methyl, ethyl
or methoxy;
as a filler, diatomaceous earth; and surfactants, polyvinyl alcohol and sodium dodecylbenzenesulfonate at a weight ratio of 50: 45: 2: 3, respectively.
The granules containing the active substance is a phenylacetanilide derivative of the indicated general formula, the fillers are bentonite and talc, the surfactants are sodium ligninsulfonate, sodium alkyl benzene sulfonate and sodium bicarbonate with mass
5: 23.75: 68.11: 1.9:: O, 475: 0.765, respectively.
An emulsifiable concentrate containing the active substance - a phenylacetanilide derivative of the indicated general formula, / solvent - xylene and surfactant - polyoxyethylalkyl ether and a weight ratio of 30:60:10, respectively.
The herbaceous composition according to the invention differs from the known irrigates by intraspecific selectivity. This makes it possible to successfully fight against various grassland sorinas in rice crops, not damaging the latter.
(molinat)
These formulations of the germicidal composition (wettable powder, emulsifiable concentrate) are prepared by known methods — by thoroughly grinding and mixing all the ingredients

Example 1. The soil from rice fields is laid in special pots. Seeds of chicken millet and long sows are sown on the surface layer and tubers of water sowing round are planted. The pots are filled with water to ensure a depth of 3 cm. Before these weeds germinate, the moistened soil is treated with pre-

The results of the experiment are presented in. . tab. 3
Example 3. The soil, taken from paddy rice plantation, is placed in special pots and seedlings or tubers of chicken millet, corn, dpinna, corn round and kamppa are planted. Then, the emulsifiable concentrate prepared according to embodiment 3 is diluted with water and the soil with seeds and tubers is treated with it. Two days after treatment, young rice plants are placed in pots at the two-leaf stage.
the amount of wettable powder obtained in accordance with option 1. Herbicidal efficacy is observed 3 weeks after treatment. Herbicidal effect is assessed on a scale from 0 to 5 points. The results of the experiment are presented in table. 2

Example 2. Special pots fill the soil from the paddy rice fields and sow the seeds of chicken millet, and grow long and lake reeds. Water round tubers are planted at the same time. The pots are filled with water to ensure a depth of 3 cm. 5 days after emergence, the weeds are moistened with a pre-determined amount of granules obtained in accordance with option 2. 3 weeks after the treatment, the degree of phytotoxicity is observed with respect to rice plants transplanted into the soil and herbicidal effect (assessed according to the scale given in example 1). The degree of phytotoxicity in relation to rice is estimated by
following standards:,,
: slight damage
Each active ingredient is tested in two, areas at different concentrations. Three weeks after treatment, the herbicidal effect and phytotoxicity of OTHomeHtno for rice are determined according to the standard method. The results of the experiment are presented in table. four.
