Embodiment 1
[0014] Example 1: Determination of the combined effect of glufosinate-ammonium and saflufenacil on purslane and goosegrass.
[0015] 1. Test agents: 96.5% glufosinate-ammonium technical; 97.4% saflufenacil technical.
[0016] 2. Test materials: purslane and goosegrass, which are weeds in the experimental field of Zhaoqing Zhenge Biotechnology Co., Ltd.
[0017] 3. Test drug preparation
[0018] Preparation of glufosinate-ammonium agent: Weigh 0.7772 g of 96.5% glufosinate-ammonium technical product, and dilute it to 500 mL with 1% acetone and 0.1% Tween-80 aqueous solution to obtain glufosinate-ammonium mother solution with a concentration of 1500 mg / L. In the determination, glufosinate-ammonium single agent or mixed agent was prepared with this mother liquor.

Embodiment 1
[0059] Preparation Method Example 1: Preparation of 20% saflufenacil·glufosinate-ammonium aqueous solution
[0060] The herbicide composition containing glufosinate-ammonium and saflufenacil consists of the following components by weight percentage: saflufenacil 4%, glufosinate-ammonium 16%, emulsifier 5%, cosolvent 10% %, warning color 5%, stabilizer 4%, antifreeze 5%, water to make up the balance. After the original medicine, solvent and auxiliary agent are mixed uniformly, the saflufenacil·glufosinate-ammonium aqueous solution of the present invention can be prepared by standing to remove impurities.
