Abstract

The use of quinoline derivatives of the formula ##STR1## against the harmful effects of herbicidally active 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)-phenoxy]-propionic acid derivatives.

Claims

1. A process for selectively controlling Avena ludoviciana, and Lolium perenne in cereal crops, which process comprises treating the cereal crops, parts of the cereal crops or cultivated by for the cereal crops with an effective amount of an antidote of formula I ##STR275## wherein R¹, R², R⁴, R⁵ and R⁶ are hydrogen, R³ is hydrogen or chlorine,

A is --CH₂ --,

Z is COOR¹² and

R¹² is an alkyl group of 4 to 11 carbon atoms and an effective amount of a herbicide of formula II ##STR276## wherein Y is --OR¹⁸ and

R¹⁸ is C₃ -C₉ alkynyl.

2. A process of claim 1 in which process 2-[4-(5-chloro-3-fluoro-pyridin-2-yloxy)-phenoxy]-propionic acid propargylester is used as herbicide.

3. A process of claim 1 in which process there is used 2-(5-chloroquinolin-8-yloxy)-acetic acid (1-methylheptyl) ester as antidote and 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)phenoxy]-propionic acid propargyl ester as herbicide.

4. A process of claim 1 in which process there is used 2-(5-chloroquinolin-8-yloxy)-acetic acid (1-methylhexyl)ester as antidote and 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)-phenoxy]propionic acid propargyl ester as herbicide.

5. A herbicidal composition which contains an effective amount of a herbicide of formula II ##STR277## wherein Y is --OR¹⁸ and

R¹⁸ is C₃ -C₉ alkynyl and and effective amount of an antidote of formula I ##STR278## wherein R¹, R², R⁴, R⁵ and R⁶ are hydrogen, R³ is hydrogen or chlorine,

A is --CH₁ --,

Z is COOR¹² and

R¹² is an alkyl group of 4 to 11 carbon atoms and a carrier therefor.

6. A herbicidal composition of claim 5 which contains as herbicide 2-[4-(5-chloro-3-fluoro-pyridin-2-yl-oxy)-phenoxy]-propionic acid propargylester.

7. A herbicidal composition of claim 5 which contains 2-(5-chloroquinolin-8-yloxy)-acetic acid (1-methylheptyl) ester as antidote and 2-[4-(5-chloro-3-fluoropyridin-2-yl-oxy)phenoxy]-propionic acid propargyl ester as herbicide.

8. A herbicidal composition of claim 5 which contains 2-(5-chloroquinolin-8-yloxy)-acetic acid (1-methylhexyl) ester as antidote and 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)phenoxy]propionic acid propargyl ester as herbicide.
