Following the rainfall received over the past 10-14 days soybean diseases have greatly increased. Septoria brown spot, target spot and soybean rust (in isolated geographic locations) have all increased throughout MS.
Over the past week, following the excessive rainfall received through most of the soybean production area, several calls have been received regarding soybean seed sprouting in the pods.
Due in large part to the continued wet weather, cotton diseases have been on the increase over the past two weeks. Boll rot, bacterial blight and target spot have all been observed throughout the MS cotton production system.
Bacterial panicle blight has been a rare disease in MS rice production systems. Over the past several years, bacterial panicle blight has only been observed in years when high temperatures occurred for extended periods of time during flowering. The specific
Over the last couple weeks, we have received numerous calls about multiple caterpillar pests in Bt cotton. By far, the most common and widespread species has been bollworm, but populations of fall armyworm are also high and we have even heard
Over the last few weeks we have been getting more and more calls about redbanded stink bug in soybeans. Redbanded stink bugs (RBSB) are voracious seed feeders, infest fields later, and are more difficult to control than greens, southern greens,
In addition to the current foliar disease situation, root diseases are becoming widely observed throughout the MS soybean production area. Two of the more commonly observed diseases over the past several weeks have been taproot decline (TRD) and root-knot nematode foliar symptoms as a result of galling. Scouting for the presence of root-knot nematodes at this point in the season will aid in decisions for next season’s crop.
Foliar diseases continue to be observed throughout the Mississippi soybean production system. Low levels of frogeye leaf spot, Septoria brown spot and target spot have been frequently observed following the rainfall of the past two weeks. The first soybean rust on soybean was observed on Friday in Rankin County, MS on a single leaf in a field of R4/R5 soybeans.
What has happened with tarnished plant bug this year? That has been the million dollar question this year in cotton. Numerous consultants have told us that tarnished plant bug populations are lower than they have ever seen in their careers
Leaf blast has been observed in the MS rice crop for the better part of the last three weeks. In most cases, lesions were observed in areas of fields where the floodwater was less than four inches.
It looks like 2016 is shaping up to be another big year for fall armyworm in rice. As a reminder, our threshold in rice at this point in the season is 5 per 10 sweeps or when significant damage occurs.
Bollworm: We have had numerous reports of bollworm (soybean podworm corn earworm) moths being flushed and small larvae in cotton and soybeans over the last couple weeks. This past week seemed to be the turning point in soybean. Nearly anyone with
Pheromone trap catches for tobacco budworm this week were at higher levels than normally seen during this time of year in all areas of the state. Bollworms were back down some this week after being quite high in some regions
As the corn crop nears maturity, knowing when you can safely terminate irrigation timing, while optimizing yield potential is likely the most important decision you will face. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Save for the appearance of a few common foliar diseases, the soybean disease situation remains fairly quiet. Septoria brown spot appears to be the most commonly occurring foliar disease. Scout fields for the presence of nematodes as well as stem diseases now to aid in next season’s decisions.
The MSU-DREC Rice Producer Field Day will be held in conjunction with the annual Mississippi Farm Bureau Federation Summer Rice Grower Meeting this year on the morning of July 19 at the Capps Center in Stoneville. The MSU-DREC Rice Field Day will
Over the last couple weeks we have begun to get numerous calls about kudzu bugs infesting soybeans. Call are coming from all over the state. We no longer keep up with county level infestations but its safe to say they
Southwestern corn borer trap counts remained very high in some areas this week. The highest counts reported were in Sunflower, Quitman, and Coahoma counties.
Over the past several years, phytotoxicity has continued to be an important topic of conversation. Phytotoxicity can ultimately result following the application of numerous fungicide products. The specific symptoms associated with phytotoxicity can appear as interveinal chlorosis (either mild, moderate
The North Mississippi Research and Extension Center Field Day is scheduled for August 11, 2016 from 8 am to 1:30 pm with lunch provided.
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 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
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.
