Does pH Affect Glyphosate Performance?

CSEF · 2010 Toxicology (Junior Division Only)

Xena L. Senn · Washington Academic Middle School, Sanger, Fresno County

Overview

Objectives/Goals My objective was to determine if lowering the pH of the mix water to a pH of 5 would decrease the performance of Glyphosate on Bermuda grass. Methods/Materials Take a Glyphosate sample mixed with water with a pH value of 5 or pH of 9 and apply both herbicide samples to 10" by 10" squares of Bermuda grass. Each pH value was tested 35 times. After a 2 day and 7 day interval, the Bermuda squares were measured with a measurement grid and performance recorded in percent. Results Glyphosate mixed with water with a pH of 5 did not perform as well as the Glyphosate mixed with water with a pH of 9 when measured at both the 2 day and 7 day intervals. Conclusions/Discussion My conclusion is that pH does affect Glyphosate performance and that Glyphosate mixed with water with a pH of 5 had a decrease in its performance.

Summary statement

Determining if lowering the pH value of the water mixed with Glyphosate would affect its performance.

Help received
