Description

I
Изобретение относитс  к химическим средствам дл  борьбы с сорной и нежелательной растительностью,. а именно к гербицидному средству, содержащему действуюшее ве1тество из. числа производных-арилоксиалканкарбоновых кислот и вспомогательные компоненты из группы жидких или твердых носителей, поверхностно-активных веществ и т.д.
Известны гербицидные средства на основе производных арилоксиалканкарбоновых кислот. К ним относитс , например, средство на основе -(пиридилокси)-фенокси -алканкарбоновых кислот и их производных I, а также на основе (4-трифторметилфенокси )-фенокси -пропионовой кислоты и ее производных 2. Однако известные средства данного типа недостаточно эффективны в отношении отдельных видов сорных растений.
Целью изобретени   вл етс  новое гербицидное средство на основе производного арилоксиалканкарбоновой кислоты, обладающее повышенной гербицидной активностью и избирательностью действи .
Указанна  цель достигаетс  тем, что в качестве действующего вещества
гербицидного средства используют производное арилоксиалканкарртоновой кислоты общей формулы I

D R
водород., хлор, бром, метил; водород, С -Сз-алкил или катион органического или неорганического основани .
Содержание действующего вещества в гербицидном средстве находитс  в пределах 1-80 вес.%.
Формы применени  действующих веществ обычные: растворы, эмульсии , суспензии, пасты, порошки и т.д. Их готов т известными приема-ми ,
Спос.об получени  соединений общей формулы I основан на реакции соответствующих 2-галогенпиридинов с производными 2-(4-оксифенокси)-пропионовой кислоты в присутствии основани . Их получают также взаимодействием 4- (2 гшрйдилокси)-фенолов с 2-галогеипропиоиовой кислотой и-ее производнылда в присутствии основани .
Ниже представлены соединени  общей формулы I, изученные в качестве действующих веществ гербицидного средства , и примеры, иллюстрирующие эффективность последнего. 5 Т а б л и ц а 1

формами действующих веществ и через 15 дней после обработки оценивали гербицидныйэффект по указанной шкале. Доза действующих веществ 4.кг/га. Результаты опыта представлены в табл.3. Поспевсходова  обработка
Пример 3.
Послевсходова  обработка.
Опыт проводили в услови х полимера 2 при достижении развити  растений 2-4 листа. (Окала оценки та же, Дл  сравнений- использовали известные герВицидные вещества:
