When should I consider replanting cotton?
Replanting is often a difficult decision.In fields with questionable stands, there are several things to consider before making a replant decision. 1) What is the calendar date? 2) What is the population of plants that will survive? 3) What is the health of those plants, especially their roots? 4) Are there large skips and frequent skips? 5) What is the productive capability of the soil, and is the field irrigated?
If plant distribution is fairly uniform in fields on productive soils, good yields can be made with low plant populations in the low 20,000 range, or as low as one per row-foot with no or few skips. If the stand is broken with numerous skips, replanting is in order at populations below 30,000 plants per acre, depending on the size and frequency of skips. Calendar date is significant. A stand you would plow up on May 1 would probably be kept on May 25.
If replanting is necessary, continue to use fungicides as appropriate. If the field has had heavy and/or frequent rains, or was flooded, additional preemergence herbicides will be needed. That decision needs to be made on a field-by-field basis. If replanting is done on the stale row, use a burn-down herbicide to kill the old stand and weeds which may have emerged on the row. This treatment could be mixed with the preemergence materials.
Here is a rule of thumb that seems to work better each year: "If you have enough cotton left to make the decision difficult, you probably have enough to keep."
As most cotton across Mississippi is setting bolls ahead of schedule this year, some fields look fantastic and others are struggling, depending on the weather and irrigation.
Lonnie Fortner has been named the Mississippi winner of the 2018 Swisher Sweets/Sunbelt Expo Southeastern Farmer of the Year award.
STARKVILLE, Miss. -- Growers may be on their way to planting more cotton in Mississippi soil than they have in 11 years, despite a late start.
Darrin Dodds, cotton specialist for the Mississippi State University Extension Service, estimated that growers will plant 700,000 acres of cotton this year. If that much gets harvested, it will be the best total since 2006, when the state produced 1.2 million acres of cotton. Last year, Mississippi cotton producers harvested 625,000 acres.
ELLISVILLE, Miss. -- Mississippi State University representatives met with agricultural clients in Ellisville recently to discuss research and education needs for 2018. More than 115 individuals attended this year's event.
STARKVILLE, Miss. -- Two highly anticipated online training modules are now available for those who plan to purchase or apply dicamba and similar herbicides.
The Mississippi State University Extension Service, in cooperation with the Mississippi Department of Agriculture and Commerce Bureau of Plant Industry, developed these new online training courses related to herbicides labeled for use with dicamba-tolerant cotton and soybeans in response to label changes from the Environmental Protection Agency.
