Morphological changes observed during the growth of wheat plant on 5 th day were 5.75 cm in length
and the color of it was fresh green. On 10 th day it was 11 cm in length and there was no difference in
color. On further days there increased in height with no prominent change in color was observed. The
differences in response to carrier volume for glyphosate may be related to water hardness, surfactant
concentration, and spray droplet dynamics.
Wheat plants that are tolerant to glyphosate application also have very good resistance to leaf rust when
the glyphosate is sprayed on the plants for a period of up to three weeks prior to exposure to leaf rust
infections. The resistance to leaf rust is due to the application of glyphosate, and not due to other
compounds present in Roundup. Glyphosate can have adverse effects on other pathogens, including
other rust fungi, additional investigation (Anderson, J.A., Kolmer 2005) of the fungicidal
properties of glyphosate are warranted, with particular attention to the timing of
glyphosate application relative to fungal infection it directly correlated the literature data.
