Soybean scouting continues throughout MS for foliar diseases. Over the past week to ten days, aerial web blight has been identified in several fields in eastern and northeastern MS. However, aerial blight has not been identified in the Delta and seems
As of now, I have had numerous reports of pyrethroid failures in soybeans targeting bollworms. Nearly everyone with soybeans at R1-R4 has bollworms at some level in the delta region of the state. So what is going on?
Irrigated Corn Verification Fields are nearly mature, but did require a final irrigation this week to provide ample moisture to sustain the crop to physiological maturity. Some slight root lodging also recently occurred, but otherwise harvest progress should commence soon. Late-planted dryland fields still have a long way to go and are under drought stress.
Over the past 7 days, numerous cotton fields have been determined to be infected with bacterial blight, caused by Xanthomonas axonopodis pv. malvacearum (formerly Xanthomonas campestris pv. malvacearum). In addition to the growing number of acres in MS having been
The soybean crop is advancing regardless of the extreme environmental conditions encountered throughout MS. At present, there are no foliar diseases of much consequence to report from either soybean sentinel plots or commercial fields. A little frogeye leaf spot has
Several fields of cotton in the Delta, as well as one field in Monroe County exhibiting symptoms of bacterial blight have been detected over the past 5 days. In addition, a significant acreage of cotton in Arkansas has been determined
Bollworm, tobacco budworm and beet armyworm pheromone trap captures remained similar to last week. Southwestern corn borer trap counts were lower this week, indicating that the second generation peak has past. One field in Leflore County had SWCB trap captures of
Regulations will go into effect after August 16, 2011 which will affect retailers, commercial applicators, custom blenders, re-fillers, and registrants of refillable pesticide containers. Essentially, these new regulations will affect those who use and handle mini-bulk pesticide containers, including growers.
Last week we started getting calls about flushing bollworm moths in soybean fields and a few fields were at or above threshold on larvae. This week was the turning point. As of today (7/15/11) we have started treating many fields.
Although many are aware of the issues that have been created by the appearance of four bract squares over the past few weeks, the magnitude of this issue warrants a final few words. First and foremost, four bract squares typically
This week we are starting to get some calls of the first soybean fields reaching threshold for bollworms. Bollworms (Corn Earworms) can be extremely devastating to soybeans because they feed directly on all fruiting structures. Many folks are also reporting
Over the last 10 days I have started getting calls about fall armyworms showing up in late planted soybeans. We see some of this every year, and it is primarily related to larvae moving off of a grass host after
There have been very few changes in the quarantine situation over the past few weeks. Litter can be hauled in Mississippi: with permits only. Within Wayne, Jones, Jasper, Perry, and Forrest counties, it may only be hauled from place to
Insect pheromone trap counts for the last week were steady to slightly lower for all species as a whole. Bollworm catches remained fairly high in some delta counties. Typically this week would have been the peak catch for second generation southwestern corn
Southern corn rust was detected in Coahoma County yesterday at VERY LOW LEVELS. This does NOT mean that a fungicide application is necessary especially since most corn has reached the dent stage throughout the general area. To date this has been the only southern rust detected in MS.
Overall not much change in insect trap counts from last week. Bollworm counts were somewhat higher in the Delta and Central MS regions, tobacco budworm counts were lower in all regions, especially in the Delta were no budworms were caught this week.
The incidence of foliar disease in cotton across MS have been on the rise over the past 5 years. In addition, fungicide applications have been suggested as a means of managing the leaf spots and increasing yield. Research trials conducted at MSU and elsewhere suggest that fungicides aren’t beneficial when it comes to enhancing cotton yield.
Preliminary yield data from the 2011 MSU Wheat Variety Trials are now available.
Much of our late March planted irrigated corn is now reaching dent stage and will continue to fill kernels for another 20 days, if we help it do so. Therefore, you do not want to forgo any practices which may mitigate stress or pest issues yet. This article highlights irrigation needs and termination during the final growth stages.
Every year when afternoon thunderstorms start popping up, the phone starts ringing about rainfastness. Rainfastness simply means the amount of time needed after application before a rainfall event for the product to still be effective. One thing I have figured
Nearly everyone who has read this blog, one of many popular press articles, or any of several periodical publications over the past year or two is aware of the problems many growers in Mississippi have with glyphosate-resistant (GR) Palmer amaranth.
At present there is still little to no foliar disease in the majority of the corn crop. Many of the calls I’ve received over the past 7 to 10 days have dealt with sun scald, herbicide injury or urea burn
Pheromone trap counts for bollworm, tobacco budwrom and beet armyworm were all similar to last week in all regions. Counts of tobacco budworm and beet armyworm are high compared to historical data, especially in the central part of the state.
Despite Mississippi generally receiving abundant yearly rainfall, we often experience substantial drought stress growing corn. The timing of rainfall and the ability of our soils to store moisture are critical to corn productivity. This article explains how drought stress and irrigation management may influence corn productivity during the early grain filling stages.
One of the biggest questions I receive each year has to do with whether or not a specific disease is present on soybean at a particular time. Most and I say most since this is a statement that can differ
