Southwestern Corn Borer Trap Counts: July 2, 2016
Southwestern corn borer trap catches appear to be peaking this week. Several counties had individual traps with numbers at or near the current threshold and a couple well above threshold. As a reminder, the current threshold is 50 per trap
Southwestern Corn Borer Trap Counts: June 25, 2016
Southwestern corn borer numbers increased significantly in some areas this week. The highest numbers were 377 caught in Leflore County and 450 caught in Coahoma County. The current threshold in the 2016 Insect Control Guide suggests spraying when 50 moths are caught
Heliothine Trap Catches, June 22, 2016
In the Delta, trap catches of corn earworm and tobacco budworm were similar to last week, which is lower than average for this time of year. However, in the Northeastern Hills, tobacco budworm catches were higher while bollworm catches were
Caterpillars Infesting Field Corn
Much of the corn has reached the reproductive stages, while some is still in the vegetative stages. Several caterpillars, including fall armyworm and corn earworm, can infest corn, especially non-Bt corn, during both stages of development.
Southwestern Corn Borer Trap Counts: June 18, 2016
Overall, southwestern corn borer traps remained low throughout the state. However, one trap in Leflore county captured 178 moths over a 7 day period. Although they do not appear to be widespread, this indicates that there may be pockets with
Pheromone Trap Counts, June 15, 2016
This week’s trap counts were similar to slightly higher than last week and last year for both bollworm and tobacco budworm. However, they are simlar to lower than long term average trap counts for this time of year. Corn is
Southwestern Corn Borer Trap Counts: June 11, 2016
All southwestern corn borer trapping locations did not report this week, but numbers were very low across the state. The highest numbers were in the south Delta, but still well below threshold with the highest number being 22 in one trap
Insect Trap Counts, June 8, 2016
Bollworm trap counts were somewhat lower this week in all counties except Lowndes. Tobacco budworm counts were slightly higher than last week, especially in the northeastern Hills region, but still not very high. Most corn is at or approaching pollination,
Transform Section 18 Approved for Use in Mississippi Cotton
The Environmental Protection Agency has now authorized the use of Transform WG (sulfoxaflor) in Mississippi for control of tarnished plant bugs in cotton. For specific details see below.
Pheromone Trap Counts, June 1, 2016
It is once again time to start posting pheromone trap results to assist you in making insect management decisions. This year we have 3-4 bollworm and 3-4 tobacco budworm pheromone traps in 5 Delta counties and 3 Northeastern Hill counties
Spider Mites Showing up in Small Cotton in MS
Spider mites have been becoming more widespread over the last two weeks. Currently we have quite a few acres requiring treatment for spider mites and several that have already received an application. The hot dry weather we have been dealing with
Thrips Pressure Starting off Heavy in MS Cotton
Calls about thrips treatments in seedling cotton have been picking up substantially this week. As ryegrass and other ditchbank hosts begin to dry down, thrips numbers will likely increase in the next couple weeks. The 100% chance of rain today (5/20) now
Thrips in Peanut: When to Spray
There are questions every year about spraying thrips in peanut. In general, we have recommended using an at-planting insecticide to manage thrips and that is adequate in most situations. However, we did a study two years ago where we sprayed peanuts
Comment Period is Open for Transform Section 18
In March, the Mississippi Bureau of Plant Industries and other states in the Mid-South submitted Emergency Exemption (Section 18) requests to use Transform for tarnished plant bug control in cotton. The reason for this request is that the original registration
Rice Seed Treatments and Cool Wet Soil Conditions
Every year we have a point in the planting season where we start getting questions about how heavy rainfall and cool temperatures affect seed treatments in rice. The one thing to remember is that the clock starts ticking on the
Cutworms Showing Up in Mississippi Crops
We have had several calls over the last week about cutworms reducing plant densities in cotton, soybean, and non-Bt corn. Based on the number of calls, it appears that cutworm populations are much higher than they have been the last several
2016 Scout Schools
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
Seed Treatments and Thrips 2016: Expectations
Although commodity prices have not been exciting for any crop we grow, Mississippi is expected to see cotton acres increase as much as 40% this year. As we have been traveling the meeting circuit, the common denominator has been, “What inputs can we cut in an off year?” This has been asked of all crops lately, not just cotton. It seems that seed treatments are the first thing that comes up during this conversation in every crop; however, this is not a viable option in cotton.
Tarnished Plant Bug IPM and Impact of the Transform Label Cancellation
We posted an article last spring about utilizing several best management practices in an overall IPM program to manage tarnished plant bug in cotton. We included a pdf that highlights all of the research we have conducted over the last
2016 Insect Control Guide Now Available
The 2016 Insect Control Guide for Agronomic Crops is now available online. Hard copies will be available in January. Notable changes this year include the removal of pyrethroid insecticides for bollworm control in all crops due to resistance and poor
