Storage stable glufosinate formulation
The present invention relates to a glufosinate-containing formulation having good cold stability, to the use of 1-methoxy-2-propanol to improve the cold stability of a formulation comprising glufosinate, and to a method for selectively controlling weeds in an area comprising applying an effective amount of the inventive formulation.
1 . A formulation comprising 12.0 to 28.0 wt.-% of L-glufosinate ammonium, 20.0 to 30.0 wt.-% of sodium lauryl ether sulfate, 4.0 to 8.0 wt.-% of 1-methoxy-2-propanol, 7.0 to 11.0 wt.-% of dipropylene glycol, 6.0 to 15.0 wt.-% of an alkyl polysaccharide, and 20.0 to 50.0 wt.-% of water, each based on the total weight of the formulation.
2 . The formulation of claim 1 ,
wherein the L-glufosinate ammonium is present in the formulation in an amount of 16.0 to 20.0 wt.-%, based on the total weight of the formulation.
3 . The formulation of claim 1 ,
wherein the sodium lauryl ether sulfate is present in the formulation in an amount of 22.0 to 28.0 wt.-%, based on the total weight of the formulation.
4 . The formulation of claim 1 ,
wherein the 1-methoxy-2-propanol is present in the formulation in an amount of 5.0 to 6.0 wt.-%, based on the total weight of the formulation.
5 . The formulation of claim 1 ,
wherein the dipropylene glycol is present in the formulation in an amount of 7.0 to 9.5 wt.-%, based on the total weight of the formulation.
6 . The formulation of claim 1 ,
wherein the alkyl polysaccharide is expressed by the general formula (II)
wherein R 2 is saturated or unsaturated C4-C24-alkyl, G is a glucose moiety, and g is an average number of 1 to 50.
7 . A method for selectively controlling weeds in an area comprising applying an effective amount of the formulation according to claim 1 to the area.
