What symptom can be caused by the drift of Glyphosate on corn?

The symptom that can be caused by the drift of Glyphosate on corn is leaf cupping. Glyphosate, a non-selective herbicide, can affect non-target plants if it drifts from the intended application area. When corn is exposed to Glyphosate, even at low levels, it can exhibit symptoms consistent with herbicide damage.

Leaf cupping specifically refers to the distortion in leaf shape, where the edges become cupped or rolled, which is a common reaction of plants that have been affected by herbicide applications, particularly those that interfere with growth hormones. This symptom is indicative of the herbicide's impact on the plant's physiological processes, causing an abnormal growth response.

Other symptoms like yellowing in whorl, short twisted leaves, and blistering are less characteristic of Glyphosate exposure specifically, as they may result from various environmental stresses, nutrient deficiencies, or damage from other types of herbicides. Understanding the specific symptomology associated with Glyphosate can aid in identifying potential issues related to herbicide drift and its effects on crops.
