Synergistic Herbicide Strategies: Optimizing Weed Control with Glyphosate and Glufosinate Ammonium




Introduction

Weed resistance presents a persistent challenge in modern agriculture, necessitating innovative herbicidal approaches. This study delves into the combined efficacy of 35% Glufosinate Ammonium·Glyphosate Ammonium saltwater solution, aiming to unravel its potential in weed control. The experiment compares this novel solution with other commonly used herbicides, shedding light on its effectiveness against non-cultivated land weeds.

Materials and Methods

To better illustrate the practical application effects of the co-formulation, we conducted the following study. The research involved the use of a range of herbicides, including 35% Glufosinate Ammonium·Glyphosate Ammonium saltwater solution, 95.5% glufosina Ammonium salt raw material. Control agents such as 200 g/L Glufosinate Ammonium SL and 72% Glyphosate Ammonium soluble granules were also included. Biological activity assessment was carried out using the room temperature potted planting method, followed by spray treatment using a fully automatic spraying tower. Field trials were conducted in non-cultivated land, with a focus on various weed species such as barnyard grass, early-maturing foxtail, and rapeseed. The experimental design included different treatments, comprising varying concentrations of the Glufosinate Ammonium·Glyphosate Ammonium saltwater solution, Glyphosate Ammonium soluble granules, Glufosinate Ammonium SL, and water control. Evaluations were performed at 14 and 28 days post-treatment.

Field Efficacy Trials

Field trials were conducted in non-cultivated land, focusing on various weed species such as barnyard grass, early-maturing foxtail, rapeseed, and others. The experimental design encompassed different treatments, including varying concentrations of the Glufosinate Ammonium·Glyphosate Ammonium solution, Glufosinate Ammonium granules, Glufosinate Ammonium aqueous solution, and water control. Assessments were made 14 and 28 days post-treatment.

Results

Table below details the weed control efficacy of different herbicides, showcasing the superiority of the 35% Glufosinate Ammonium·Glyphosate Ammonium saltwater solution. The solution's efficiency, measured in plant control and fresh weight control, demonstrated significant improvement compared to other tested herbicides. The study emphasizes the statistical significance of these results, enhancing the credibility of the findings.
