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,
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
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
We had an App created that will allow you to review the program and register straight from your Smart Phone for the 2015 Mississippi Row Crop Short Course Nov. 30th – Dec. 2, 2015 at the Cotton Mill District in
Bollworm trap catches remained similar to last week, which is somewhat lower than average for this time of year. Tobacco budworm trap catches were somewhat higher this week. As most crops are now beyond the vulnerable window for damage from
Bollworm moth trap catches were slightly higher in most counties this week but are generally lower than average counts for this time of year. Tobacco budworm moths continued to be caught at relatively low levels. Continue to monitor susceptible fields
Bollworm counts fell some for the second consecutive week, a clear indication that the generation that developed in corn has mostly emerged and we are now in the larval stage of the next generation. Tobacco budworm were similar to the
There has always been a struggle with properly defining the correct cutoff for spider mites in cotton in the Mid-South region. For years we always loosely considered Node Above White Flower 5 (NAWF5 = Cutout) and 650 heat units the
We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.
Bollworm moth catches remained strong for another week as the generation that passed through corn continues to emerge. Continue to monitor for bollworms in all susceptible crops throughout the state. Tobacco budworm catches were a little higher in a few
Over the last week we have been getting a lot of calls about extremely high bean leaf beetle numbers. Most calls have come from the Northwest Delta region of the state. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding
Pheromone trap counts for bollworm were stable this week in the Delta while rising in the Northeastern region of Mississippi. Based on several weeks of fairly high bollworm moth catches, protection is likely needed in many fields against bollworm throughout the
After rising for several weeks, bollworm pheromone trap counts decreased some in the southern Delta region while slightly increasing in the hills and North Delta regions this week. This likely indicates that we are at peak moth flight for this
Bollworm trap numbers in the Delta and Hill regions have continued to increase some over what was reported last week. Southwestern corn borer numbers are still very high in some areas of the Delta and sprays may be needed in
The biggest change for this week is the rise in southwestern corn borer trap counts. High numbers were spotty in the Delta with one Leflore county trap recording 668 moths in a week. Coahoma, Quitman and Sunflower counties were the
Bollworm pheromone trap counts were similar to last week and remain fairly low compared to historical averages. Tobacco budworm counts were slightly higher this week, but are still low fairly low. Southwestern corn borer trap catches have started to increase
It appears that we are beginning to see the next generation of bollworm moths flying this week. Trap catches in most counties were higher this week than last week. Catches are still relatively light compared to long term averages, so
Pheromone trap catches for bollworm, tobacco budworm and southwestern corn borer were very low throughout the state this past week. However, bollworm catches were slightly higher than last week, so we may be seeing the first moths of the next
This is the first week this year I am reporting trap counts but we have had most traps out for at least 2-3 weeks. Overall trap catches have been average to light. This week, the trap catches for corn earworm
Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm.
Although every major field crop we grow in Mississippi is responsive to at planting insect protection; field corn is perhaps the most consistent. Why is this?
There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases.
Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower this week.
This week’s bollworm trap catches were similar to slightly higher than last week, while tobacco budworm trap catches fell slightly for the week. The trap catches are typical for this time of year, so expect moderate worm pressure in all sensitive crops.
Bean leaf beetle numbers have been increasing steadily over the last couple weeks. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by
