The diseases encountered throughout the MS corn crop continue to be the same. Northern corn leaf blight and southern corn rust continue to be the two most talked about diseases. Annually, as the corn crop matures, NCLB appears to increase since lesions reach their most mature expression. Southern corn rust has been observed in 19 MS counties to date (July 11, 2015). Fields where the disease has been observed typically contain a light dusting of rust.
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
Considering the abundant rainfall during the July 4th week and the crop progressing closer to maturity, some are likely wondering whether if the 2015 corn crop is finished. This article discusses how to make that call and determine timing for irrigation termination.
Corn diseases have started to be more commonly observed throughout the MS corn production area. Given the time of year in both calendar date and crop stages (post-tassel) several corn diseases are being observed more often. Northern corn leaf blight, southern corn leaf blight, and Diplodia ear rot have all been observed over the last two weeks. Southern corn rust made an appearance earlier than normal; however, the disease is considered to be at extremely low levels at this time even though five counties (Adams, Claiborne, Coahoma, Forrest, Stone) have been observed to contain infected corn plants.
An agronomic crops turn row talk will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6 on July 9, 2015. The field day will be held in the cotton field
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
Pre-registration is now open for the upcoming Row Crop Technology Showcase events hosted by Mississippi State University. These events will be held at the following locations: Dundee – Douglas and Chris Hood’s farm – July 7 Brooksville – MSU Black Belt
An agronomic crops field day will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6. The field day will be held in the cotton field on the south side of the road. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
For the most part, the corn disease situation has been quiet. Limited occurrences of common rust and northern corn leaf blight have been observed in some Delta fields. With the cooler and wetter conditions encountered early in the season it is possible that some uncommon diseases could be encountered.
The upcoming Row Crop Technology Showcase events hosted by Mississippi State University have been mentioned a couple of times on Mississippi-crops.com; however, we now have a list of topics that will be covered at each event as well as credits
By Keri Collins Lewis MSU Ag Communications STARKVILLE, Miss. — “Just mentioning bees and pesticides in the same sentence is sure to get a buzz,” said Angus Catchot, an entomologist with the Mississippi State University Extension Service. Media skirmishes about
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
Abundant rainfall has soaked corn fields for extended time during April and late May, exposing nitrogen fertilizer to potential loss. This article gives guidelines for estimating potential N loss.
More growers are implementing different “tassel shot” inputs as part of their corn management program. Wet weather and other issues may further complicate application timing of such inputs. This article discusses whether specific timing makes a big difference or not?
As a lot of our corn approaches tassel, issues associated with tire traffic soil compaction are becoming more evident. This article discusses the consequences.
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, weed identification, and
The recent stretch of dry weather has prompted much conversation about the proper time to initiate irrigation for corn. This scenario usually generates a lot more anxiety than necessary because early season wilting is certainly not something we are very accustomed to.
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva.
Abundant spring rainfall can create havoc with corn nitrogen management by delaying fertilizer application and also promote massive nitrogen loss. These strategies should help enhance crop response during challenging conditions.
Calls are starting to come in about stink bugs in heading wheat. It is not uncommon to find numerous stink bugs in wheat after head emergence. Species attacking wheat are typically rice stink bug and brown stink bugs but greens can sometimes be found. While it may seem very alarming, keep in mind it takes extremely high numbers to cause economic damage to heading wheat.
According to the National Agricultural Statistics Service in Mississippi, there were 1.8 days suitable for fieldwork for the week ending Sunday, April 19, 2015. Topsoil moisture supplies were 0 percent very short, 1 percent short, 37 percent adequate, and 62
I have recently received a few call about slugs in corn and soybeans. I suspect this will increase when more crops emerge in the Hill region of the state as well. Slug problems usually start on corn first, then move to soybeans, then cotton in our area. This is only because we typically plant in this order. Slugs have been a sporadic problem in MS row crops over the years with increased occurrence since 2004. This has been exclusively a no-till or reduced till problem, particularly no-till behind a grass crop like corn or grain sorghum. Cool wet years are particularly favorable for slug problems to develop.
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, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all major row crops, and fertilizer characteristics. CEU’s Provided: Nutrient Management = 1.5, Integrated Pest Management = 3, Crop Management = 1
Much like the last 2-years, as rains delay corn planting progress, more concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states new guidelines for late corn plantings based upon recent MSU research.
