What causes cupping in leaves?

Leaf cupping and rolling in vegetables can be caused by virus diseases, aphid infestations, herbicides and growth regulators. However, late spring and early summer is the time of the year that we often see leaf cupping and rolling disorders appear in vegetable crops that are not related to pests or chemicals.

What causes soybean leaves to cup?

The soybean plant must metabolize the herbicides, whether a PPO, ALS or acetamide chemistry. All of this takes energy. Applying herbicides, by nature, results in a certain stress to the plant. This stress can cause a slight, temporary imbalance in hormone levels at the tip of the plant, and we get leaf cupping.

What is leaf puckering?

Some tropical species naturally exude a slight sticky residue (generally termed “exudate”) from their leaves when they are newly expanding/unfurling, which can act as a natural adhesive if it doesn’t dissipate on its own or get rinsed away (as it might in rainfall in nature).

What are Enlist soybeans?

Why are the leaves on my soybeans cupping?

Answer: The following information was provided by Dr. Tom Jordan, Weed Science Specialist. Leaf cupping of soybeans has been wide spread through the Midwestern states this year. If the field does not show a drift pattern which is associated with an application to a near by corn field, then there are two possibilities which may explain the injury.
