Description
Изобретение относитс к химическим способам борьбы с сорной и нежелательной растительностью.This invention relates to chemical methods for controlling weeds and unwanted vegetation.
Целью изобретени вл етс усиление гербицидного действи и улучшение избирательности способа борьбы с сорн ками, основанного на использовании производного сульфонилмочевины.The aim of the invention is to enhance the herbicidal action and improve the selectivity of the weed control method based on the use of a sulfonylurea derivative.
II р и м е р 1. Получение Н-(3-ди- метиламинокарбонил-пиридин-2-ил-суль- фонил)-(4,6-диметоксипиримидин-2- ил)-мочевины (соединение А).II p. Example 1. Preparation of H- (3-Dimethylaminocarbonyl-pyridin-2-yl-sulfonyl) - (4,6-dimethoxypyrimidin-2-yl) -urea (compound A).
К суспензии 0,5 г (2,2 ммоль) 3- Н,М-диметиламинокарбонил-2-аминосуль- фонилпиридина и 0,6 г (2,2-ммоль) 4,6- диметоксипиримидин-2-ил-фенилкарбама- та в 3 мл ацетонитрила добавл ют , 0,32 мл (2,2 ммоль) 1,8-диаэабицикло- (5,4,0)ундец-7-ена. Полученный раствор перемешивают при комнатной температуре в течение 7 мин, добавл ют 6 мл воды и 10%-ную сол ную кислоту (по капл м ) , выпавший осадок отфильтровывают и получают 0,75 г целевого продукта с т.пл. 142-159°С.To a suspension of 0.5 g (2.2 mmol) of 3-H, M-dimethylaminocarbonyl-2-aminosulfonylpyridine and 0.6 g (2.2 mmol) of 4,6-dimethoxypyrimidin-2-yl-phenyl carbamate in 3 ml of acetonitrile, 0.32 ml (2.2 mmol) of 1,8-diaebicyclo-(5.4,4) undec-7-ene is added. The resulting solution was stirred at room temperature for 7 minutes, 6 ml of water and 10% hydrochloric acid (dropwise) were added, the precipitated precipitate was filtered off and 0.75 g of the title product was obtained with mp. 142-159 ° C.
П р и м е р 2. Определение гербицидного действи .EXAMPLE 2: Determination of herbicidal action.
Специальные сосуды заполн ют пес- чано-нзвестковой почвой и высевают в нее семена опытных растений. Почву с семенами обрабатывают раствором активного вещества в нефитотоксичном растворителе до по влени всходов. Контролем служат необработанные растени . Оценку гербицидного действи провод т через 24 дн после обработки по шкале от 0 до 100 (0 - отсутствие эффекта, 100 - полна гибель растений ).Special vessels fill the sandy-sandy soil and sow seeds of experimental plants in it. The seed soil is treated with a solution of the active substance in a non-phytotoxic solvent until germination. The controls are untreated plants. Evaluation of the herbicidal action was carried out 24 days after treatment on a scale of from 0 to 100 (0 - no effect, 100 - complete death of plants).
Опытные растени , выращенные в услови х теплицы до стадии 14 дней, обрабатывают растворами активного вещеслExperimental plants grown under greenhouse conditions up to the 14-day stage are treated with solutions of the active compound.

Дл сравнени используют известное , гербицидно-активное вещество: N-(3- метил-пиридин-2-ил-сульфонил)-N1-(4,6- диметоксипиримидин-2-ил)мочевину (соединение В).A known herbicidally active substance is used for comparison: N- (3-methyl-pyridin-2-yl-sulfonyl) -N1- (4,6-dimethoxypyrimidin-2-yl) urea (compound B).
Результаты довсходовой обработки jg растений приведены в табл. 1 , а после- всходовой обработки - в табл. 2.The results of pre-emergence treatment jg plants are given in table. 1, and after-germination treatment - in table. 2
