Abstract

Inventia se refera la o compozitie erbicida lichida constituita din 20 ... 70 % compus erbicid cu formula generala I : (vezi formula în pag.1) în care R reprezinta alchil cu 1 ... 4 atomi de carbon, eventual substituit cu halogen; R&lt;sub&gt;1&lt;/sub&gt; reprezinta un halogen sau un alchil cu 1 ... 4 atomi de carbon; R&lt;sub&gt;2&lt;/sub&gt; reprezinta hidrogen alchil cu 1 ... 4 atomi de carbon sau (vezi formula în apg.1) în care R&lt;sub&gt;a&lt;/sub&gt; reprezinta un radical alchil cu 1 ... 4 atomi de carbon sau R&lt;sub&gt;1&lt;/sub&gt; si R&lt;sub&gt;2&lt;/sub&gt;, luati împreuna, reprezinta alchilen cu 3 ... 6 atomi de carbon ; R&lt;sub&gt;3&lt;/sub&gt; reprezinta hidrogen sau alchil cu 1 .. 4 atomi de carbon; R&lt;sub&gt;4&lt;/sub&gt; reprezinta hidrogen sau un radical alchil cu 1 ... 4 atomi de carbon; R&lt;sub&gt;3&lt;/sub&gt; reprezinta hidrogen sau un radical alchil cu 1 ... 4 atomi de carbon; R&lt;sub&gt;6&lt;/sub&gt; reprezinta hidrogen sau alchil cu 1 ... 4 atomi de carbon; R&lt;sub&gt;7&lt;/sub&gt; si R&lt;sub&gt;3&lt;/sub&gt; sunt, independent, hidrogen, halogen - alchil cu 1 ... 4 atomi de carbon, alcoxi cu 1 ... 4 atomi de carbon, OCF&lt;sub&gt;3&lt;/sub&gt;, cian, nitro, halogen-alchil cu 1 ... 4 atomi de carbon, R&lt;sub&gt;b&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt;, în care n este un numar întreg, zero sau 1 sau 2 si R&lt;sub&gt;b&lt;/sub&gt; reprezinta alchil cu 1 ... 4 atomi de carbon; -NR&lt;sub&gt;c&lt;/sub&gt;R&lt;sub&gt;d&lt;/sub&gt; în care R&lt;sub&gt;c&lt;/sub&gt; si R&lt;sub&gt;d&lt;/sub&gt;sunt fiecare, independent, hidrogen sau alchil cu 1 ... 4 atomi de carbon, cu conditia ca R&lt;sub&gt;7&lt;/sub&gt; nu The invention relates to a liquid herbicidal composition consisting of 20 ... 70% of a herbicidal compound of the general formula I (wherein R is alkyl of 1 to 4 carbon atoms optionally substituted by halogen ; R &lt; sub &gt; 1 &lt; / sub &gt; represents a halogen or an alkyl of 1-4 carbon atoms; R &lt; sub &gt; 2 &lt; / sub &gt; represents hydrogen alkyl of 1-4 carbon atoms or (see the formula in app. 1) wherein R &lt; a &gt; a &lt; represents an alkyl radical of 1 to 4 carbon atoms or R <1> <1> <sub> and R &lt; 2 &gt; taken together represent a C3-6 alkylene; R &lt; sub &gt; 3 &lt; / sub &gt; represents hydrogen or alkyl of 1-4 carbon atoms; R &lt; sub &gt; 4 &lt; / sub &gt; represents hydrogen or an alkyl radical of 1-4 carbon atoms; R &lt; sub &gt; 3 &lt; / sub &gt; represents hydrogen or an alkyl radical of 1-4 carbon atoms; R &lt; sub &gt; 6 &lt; / sub &gt; represents hydrogen or alkyl of 1-4 carbon atoms; R &lt; sub &gt; 7 &lt; / sub &gt; and R &lt; sub &gt; 3 &lt; / sub &gt; are independently hydrogen, halo-alkyl of 1-4 carbon atoms, alkoxy of 1-4 carbon atoms, OCF3-> 3-cyano, nitro, halo-C1-6alkyl. 4 carbon atoms, where R is a whole number, zero or 1 or 2, and R <sub> b> </ sub> SO < represents alkyl of 1-4 carbon atoms; -NR &lt; sub &gt; C &lt; / sub &gt; R &lt; sub &gt; d &lt; / sub &gt; in which R &lt; sub &gt; c &lt; and R &lt; a &gt; are independently each independently hydrogen or alkyl of 1-4 carbon atoms, provided R &lt; 7 &gt; not
