Bollworm moth catches in pheromone traps were down this week to levels about average for this time of year. Tobacco budworm moth catches were zero in nearly all traps, so all heliothine eggs should be assumed to be bollworm at
Southwestern corn borer trap counts increased again this week in several counties. Traps in Leflore, Carroll, and Tate counties exceeded the current threshold of 100 per trap. As a reminder, corn is considered safe from yield losses from southwestern corn
Bollworm moth trap catches were up this week compared to last week as expected. Moths are emerging from corn now and will be primarily laying their eggs in cotton and soybeans at this time, so be attentive in scouting these
Overall, southwestern corn borer trap numbers are beginning to decline. Only one location in Leflore county exceeded the threshold of 100 per trap this week.
There are several biological insecticide options labelled in soybean; however, the most readily available and widely used product is Heligen. In the last week, many people have asked about the use of Heligen with the low bollworm numbers showing up
Dr. Erick Larson and Corn Verification Program assistant Mr. Nolan Stapleton discuss one of the most important decisions yet to make – which is when can we terminate irrigation in corn.
Bollworm moth trap catches were generally down this week from last week and were fairly average for this time of year. Tobacco budworm catches continued to be low, also about average for this time of year. However, as corn is
The corn agronomy guys are also recording Mississippi Crop Situation Podcasts. We are using this format to share our latest recommendations and issues we are finding in the Corn Verification Program and grower fields throughout the state.
This last week there have been reports of bollworm eggs starting to show up in Mississippi Cotton. Generally speaking, in a normal year the bollworm flight would begin around July 4th, and peak around the 15th. The wet spring pushed
After reporting the first week of catches in the “normal” range last week, bollworm traps were filled with a unusually large number of moths this week, especially in the Northeastern part of Mississippi. Tobacco budworm trap catches remained at average
One of the more difficult messages we must tell farmers: “You know all that money you just spent on fertilizer? Only some of it is going to be used by your crop this year.” With nitrogen (N), up to half
http://extension.msstate.edu/mississippi-crop-situation/audio/2020/rice-insect-update Bobby and Jason sit down with Jeff to discuss insect management in rice and what to look for moving forward into the year
http://extension.msstate.edu/mississippi-crop-situation/audio/2020/prepare-for-the-bollworm-flight Bobby sits down with the entomology team (Angus, Jeff, Don, and Whitney)to discuss the impending bollworm flight, what to look for and how to move forward.
http://extension.msstate.edu/mississippi-crop-situation/audio/2020/rainfall-and-crop-protection-product-efficacy Bobby and Jason sit down with Jeff and Angus to discuss how this year’s consistent wet weather influences Herbicide and insecticide efficacy.
The presence of foliar diseases in the MS corn production system has certainly increased over the past several weeks. In general, the presence of disease increases as the corn crop ages. Questions regarding common and southern rust, Curvularia leaf spot, Diplodia leaf streak, and Physoderma brown spot have been posed over the past several weeks. Information regarding the aforementioned diseases is contained in the current blog post.
Trap count continue to increase in many regions of the state, but few are at threshold. As a note, the 2 traps that captured high numbers of moths in Tate county last week were knocked down this week and are
After two months of bollworm trap catches running higher than normal, this week the catches are similar to long-term averages. Tobacco budworm catches were also about average for this time of year.
With the increase of rain showers this week and tarnished plant bug numbers starting to pick up in some places, now is a good time to revisit the impact of rainfall on insecticide performance. Rainfastness is a complex topic because
Trap counts for southwestern corn borer are highly variable this week. We did have two locations in Tate and Leflore Counties that exceeded the threshold this week. As a reminder, thresholds for southwestern corn borer suggest spraying non-Bt corn 7
Bollworm pheromone trap catches were higher than long-term averages again this week as they have been all year, while tobacco budworm catches were about the same as long-term averages. As most corn is advancing past the green silk stage, more
Corn progresses through six stages as ears develop through reproductive growth stages. Identification of these stages can be helpful for timing development, making prudent management decisions and anticipating crop response to practices and environmental conditions.
Bollworm pheromone trap catches were not extremely high this week, but June overall set a new high average trap catch and it the high catches were distributed among most monitored counties. To give some perspective, the highest previous years of
Bollworm pheromone moth trap catches have continued to be very high again this week in nearly all traps across the state. Tobacco budworm trap catches were also high in a few traps, suggesting that worm pressure from both species could
