Limiting the Spread of Fusarium Wilt Race 4, a New Disease of Cotton in Texas

by Dr. Tom Isakeit, Extension Plant Pathologist and Dr. Gaylon Morgan, Extension Cotton Agronomist During the summer of 2017, a new race of the Fusarium wilt fungus (Fusarium oxysporum f. sp. vasinfectum)  infecting cotton was confirmed in many fields in El Paso and Hudspeth counties.  This particular variant is known as “race 4” (FOV4).  Previously, FOV4 was limited to the San Joaquin Valley of California.  With plant pathogens, a race is defined as the ability to cause, or not cause disease, in particular varieties of the host plant. … Read More →

Managing Volunteer Corn in Cotton

by Jourdan Bell, Assistant Professor and Extension Agronomist, Amarillo, Texas; Peter Dotray, Professor and Extension Weed Specialist, Lubbock Texas Volunteer corn can be a significant problem in corn:cotton rotations under all tillage systems, but especially in no-till and limited tillage systems. Volunteer corn can result from grain loss at harvest due to poorly adjusted combines, late season hail damage, hybrid selection with poor ear retention, and/or lodged corn plants that dropped corn. If ear rots are present during the corn phase of the rotation, producers may opt to… Read More →

Did recent rains come too late for the South Texas cotton crop?

by Josh McGinty and Gaylon Morgan, Texas A&M AgriLife Extension Service The 2018 season in South Texas has been a tough one. In southernmost areas, a dry winter and spring meant planting moisture was scarce, while excessive rainfall was a common problem that delayed field preparation and planting in the Upper Gulf Coast. Since planting, excessive heat, wind, and very limited rainfall has been a common occurrence across South Texas, leading to severe moisture stress and early cutout (5 nodes above white flower) in many fields. Then on… Read More →

Blacklands and River Bottom Insect Pest Update – June 14

by Dr. David L. Kerns, Professor and IPM Coordinator Crops have been suffering from intense heat and lack of moisture over the past 2 weeks but we are hoping for some relief over the next 3 to 4 days.  The high temperatures and lack of moisture have contributed significantly to some severe pest problems, namely cotton fleahoppers and spider mites.  As vegetation in the landscape dries up, these pests are forced to seek other food sources and have moved into cotton throughout much of the Blacklands and the… Read More →

Corn Growth Stages and Post Emergent Herbicide Timing

by Jourdan Bell, Texas A&M AgriLife Assistant Professor and Agronomist – Amarillo Post emergent herbicide applications are necessary for season long weed control. Post emergent corn herbicide labels define the latest growth stage for which herbicide applications can be made without causing crop injury. Herbicide applications past the recommended application stages can result in significant crop injury. For some herbicides, later applications can be made according to the label, but drop nozzles are recommended to prevent herbicides being sprayed in the whorl. Some herbicide labels provide a recommended… Read More →
