What percentage of my crop should I plant in B.t.?
This depends on a number of factors centered around a producer's assessment of the threat of potential insect pest damage, especially by tobacco budworm, and the agronomic performance of selected B.t. varieties. The average has been between one-third and one-half of cotton acres on Mississippi farms to be B.t. acres. Unfortunately, tobacco budworm populations can not be predicted in advance, and many growers in Mississippi remember the devastation caused by this pest in 1995. Also, remember that other products for controlling tobacco budworm are available, such as Tracer.
Cotton and corn acreage in Mississippi are more than 30% below March projections, while growers of soybeans and peanuts planted much more than initially forecasted.
STARKVILLE, Miss. -- Row crop growers in Mississippi used a relatively dry May to make up for planting time lost earlier in the spring due to wet weather and soggy fields.
As of May 24, planting progress for the state’s four major row crops was slightly behind their five-year averages but ahead of where it was at that time in 2019.
The Mississippi State University Extension Service has a new cotton specialist.
Brian Pieralisi was appointed to that role on April 1. He replaced Darrin Dodds, who took the helm of the university’s Department of Plant and Soil Sciences.
STARKVILLE, Miss. -- Weather always plays a role in the spring planting decisions of Mississippi row-crop producers, but the market impact of the ongoing COVID-19 pandemic is another variable they will have to consider in 2020.
STONEVILLE, Miss. -- Pathologists with Mississippi State University will be monitoring a relatively new plant disease in state cotton fields once the growing season is in full swing.
Cotton leafroll dwarf virus, or CLRDV, was first reported in Alabama in 2017. It is closely related to a cotton virus known to occur in South America. Historically, that virus has caused up to 80 percent yield losses in Brazilian cotton fields.
