Boron Deficiency

Boron deficiency is perhaps wrongly accused of more problems than any other nutrient. Boron is very water soluble and deficiency is related to soil type, soil resource regions, organic matter content and timing of lime materials (pH). Symptoms are generally distinct, and descriptions of this disorder are quite similar across a larger range of environments. Petioles of younger leaves will be short and thick, with dark concentric bands along their length. It appears that the gossypol glands line up and arrange themselves in a "coon tail" arrangement. Flowers may also be distorted in shape. With severe boron deficiency, the terminal may be aborted or become deformed. The pith inside petioles of leaves or bolls may turn brown. Boron is required for normal flower development. Flower and boll shedding may increase as the level of deficiency increases.

Local University and Extension recommendations for boron applications should be followed closely. Some states recommend larger quantities of boron than others. In Misssissippi boron is recommended on hill area soils, recently limed soils and low organic matter sandy soils of the Delta. Generally the Delta region does not respond to boron. Sometimes irrigation water will contain sufficient levels of boron. Not all square, flower or boll shedding is due to boron deficiency problems. Follow your local recommendations with this micronutrient.

STARKVILLE, Miss. -- Cotton leafroll dwarf virus is capable of causing significant yield loss and was reported for the first time in Mississippi earlier this year.

The implications of this disease will be a major focus of the 2019 Mississippi State University Row Crop Short Course Dec. 2-4 at the Cotton Mill Conference Center in Starkville. This course is hosted by the MSU Extension Service and Mississippi Agricultural and Forestry Experiment Station.

Parts of Mississippi’s landscape are turning white, but unlike some northern areas, this coloration is caused by cotton bolls opening for harvest, not snow accumulation.

All of Mississippi’s 2019 cotton crop has emerged, but it’s off to a slow start.

Of approximately 700,000 acres of cotton planted statewide this year, 57% is rated fair or worse by the U.S. Department of Agriculture as of July 8.

Although numbers on paper look about right for Mississippi row crops, the reality is actually quite grim in places.

HAMILTON, Miss. -- Determining the extent of tornado damage to farms in Monroe County will take weeks, but video shot from flying drones will speed up the process.

Mississippi State University Extension Service personnel have been assisting in relief efforts since the morning after an EF-2 tornado on April 13 damaged more than 140 homes in Hamilton, claiming one life and injuring 19 others.
