At present, low levels of foliar disease continue to be reported from some corn fields throughout the Delta. Over the past week more common rust has been identified throughout the corn canopy. I’ve received several telephone calls questioning whether or
2011 is shaping up to be one of the more challenging years we have faced in some time. While no year can be considered normal, difficult weather conditions have tested the mettle of many this year. Flooding, delaying planting, and
On Thursday the United States Department of Agriculture released its monthly World Agricultural Supply and Demand report (WASDE). The June report was the second that revealed projections regarding the current growing season for crops. The report continued the ongoing theme
Pheromone trap counts for the week ending on 6-9-2011 show higher tobacco budworm and beet armyworm counts from the previous week. Corn earworm counts were similar to last week. All three of these insects are at levels where treatable larval populations
MSU Extension Service and MAFES researchers have compiled the following suggestions and information regarding replanting and managing row crops after the flood. Also included is post-flood crop insurance information.
At present, and generally due to the hot and dry conditions, little if any foliar disease is present in the Mississippi corn crop. On Friday (June 3) I scouted fields in the Tchula/Thornton area. The particular fields were dryland corn
Variability between people using sweep nets can be huge. Assume four people go to the field and take 100 sweeps each. I would almost guarantee you that each will come back with 4 different counts even if the insects are perfectly uniform.
Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working.
Pythium seedling diseases and fungicide seed treatments Little if any information seems to exist regarding the specific fungicide seed treatment suggestions that would follow extended periods of soil flooding. In the past, most of the published research has been conducted
Funding has been secured to monitor for soybean rust from the United Soybean Board and to conduct a general soybean disease monitoring program through funding from the Mississippi Soybean Promotion Board. As in the past, soybean sentinel plots were planted
Corn earworm (bollworm) pheromone trap counts were higher this week, so larvae should be expected in vulnerable crops shortly. Tobacco budworm counts were also higher except in the Delta where none were caught this week. Southwestern corn borer counts are
Litter can be hauled in Mississippi: with permits only! However in Wayne, Jones, Jasper, Perry, and Forrest counties, it may only be hauled from place to place within the county. Litter may be moved out from other production counties. Permits
False chinch bugs can be a major problem in cotton and soybean when they reach outbreak levels. Every few years in MS we see some fields with extremely high numbers. They are commonly found in dry years and seem to
In an effort to aid Mississippi producers in their decision making process a statewide survey was conducted to determine where glyphosate and/or ALS-resistant Palmer amaranth was present in the state.
While we have quite a few corn fields beginning to tassel, many more are have a little ways to go. There is a period of about 10-14 days when ears shoots become visible or begin to bulge on the side
Based on calls I have received over the last week and what I am seeing in my own research plots, this is shaping up to be a big year for threecornered alfalfa hoppers
Over the past 4 updates I’ve attempted to present data that suggests the best time to apply a fungicide is in response to a foliar disease that could potentially reduce yield. In many situations particular fungicide products are being touted
Much has been made of the ability of strobilurin fungicides to prevent corn from lodging, typically towards the end of the season. Since 2007 I have received countless calls that have gone something like “we sprayed a field with fungicide
Since 2007, fungicide products containing a strobilurin active ingredient have been suggested to increase plant “greenness†or allow the plants to stay greener longer in the field following a tassel (VT) application. Increased green plant tissue has been stated to
The quarantine on poultry litter movement in Mississippi continues, however there are new, very specific guidelines for various locations in the poultry production area. Call the Mississippi Board of Animal Health at 601-359-1170 or 888-646-8731 to determine the guidelines for
Many producers have utilized paraquat, sold under the trade name Gramoxone Inteon®, to control emerged weeds at planting. Often times a chemical manufacturer will modify a herbicide formulation to create a safer, more stable, and/or effective herbicide. However, a recent formulation change in Gramoxone Inteon has resulted in some mixing issues in some parts of Mississippi.
From 2007 through 2009 Mississippi State University extension and research personnel were involved in a large corn fungicide research effort funded by the Mississippi Corn Promotion Board. Except for situations where corn was planted on experiment stations (Brooksville, Pontotoc, Raymond,
Weekly pheromone trap captures from Northeast, Central and Delta regions of Mississippi are reported. Catches indicate moderate bollworm pressure with very few tobacco budworms and beet armyworms caught during the week of May 19-26. Southwestern corn borer pressure is generally light
This year there will be three insect scout schools provided. Each insect scout school will cover insect pests of cotton, soybeans, and corn. Scout schools are free of charge and open to everyone. Detailed descriptions of pest biology, sampling, and
By now everyone is fully aware that we have been and still are experiencing extremely high levels of thrips in cotton. To date, many fields have been treated with foliar insecticides and several have required repeat applications due to extremely high numbers and frequent re-infestations.
