Grain Sorghum – Sugarcane Aphid found in Southeast Missouri
White sugarcane aphid (Melananphis sacchari) have been found in Southeast Missouri.
Suggestions by Scott Stewart, IPM Extension Specialist University of Tennessee – Jackson:
- Just because aphids are present, does not mean you are at threshold.
- Make sure you know how to tell white sugarcane aphids from the corn leaf aphid and the yellow sugarcane aphid. (Links below have pictures to help identify aphids).
- Start looking and scout frequently once aphid are found in your grain sorghum field.
- Make an insecticide application when 30-50% of plants have aphids present AND there are multiple spots in a field where 100 ore mere aphids are present on a leaf.
The two products available under section 18 label are Sivanto (Bayer Crop Protection) and Transform (Dow Agro Services).
