Abstract

The invention relates to a weeding composition and application thereof, in particular to a microemulsion containing glufosinate-ammonium, benzofluorfen and bentazone. The microemulsion is characterized by being prepared from, by weight, 1-20% of glufosinate-ammonium, 0.1-10% of benzofluorfen, 10-20% of bentazone, 10-15% of solvent, 5-10% of cosolvent, 1-33% of surface active agent, and the balance soft water. The microemulsion is especially suitable for preventing and killing off the weeds which are difficult to control, such as Cyperus rotundus L. and Cyperus difformis L.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a microemulsion containing glufosinate-ammonium, aciflufen and bentazone. Background technique [0002] Microemulsion (microemulsion, ME) is a transparent single-phase liquid with water as the base, no or only a small amount of organic solvent, and an appropriate amount of surfactant and other additives. The microemulsion uses water as the main solvent, which not only saves a lot of organic solvents, but also greatly reduces the pressure on the environment after the application of the agent, which is of great significance for maintaining the agricultural ecological environment and is conducive to the sustainable development of agriculture. [0003] In the prior art, there are already compositions containing glufosinate-ammonium and acifluorfen. For example, patents CN1169099A, CN1312683A, CN102763676A, and CN105613572A all disclose compositions containing glufosinate-ammoniu...
