A corn, cotton, peanut, and soybean field day is scheduled for June 17th at the Delta Research and Extension Center in Stoneville, MS. The general theme of the field day will include pertinent information for mid-season row crop issues. . . . → Read More: Delta Research and Extension Center’s Agronomic Crops Field Day, June 17, 2014
We have been getting a lot of questions the last 7 to 10 days about potential injury or problems associated with mixing thrips insecticides with POST herbicides over cotton. This will no doubt be controversial, but we are going to lay it out like we would if you called. . . . → Read More: Mixing Thrips Insecticides With Post Herbicides: Yes or No?
I have had several folks asking if there is a time when thrips should be treated in soybeans. Ordinarily thrips are not a problem in soybeans. Cotton and soybeans are completely different when it comes to how the plant can tolerate thrips. Soybeans are not nearly as sensitive to thrips as cotton and therefore can tolerate high numbers of thrips without yield loss. . . . → Read More: Should You Ever Treat Thrips in Soybeans?
I have gotten numerous calls about slugs this year in all crops but lately in cotton and soybean. Slug problems usually start on corn then soybeans then cotton in our area. This is only because we typically plant in this order. We have had isolated problems with slugs since 2004, some years worse than others. . . . → Read More: Slugs – A Persistent Problem in Cool Years
Many of you have heard us talk about the declining efficacy of seed treatments against thrips throughout the winter meeting circuit. We started seeing the first signs of inadequate control about 4 years ago and the problem has seemed to get worse every year. Last year, most of the cotton in Mississippi was sprayed for thrips at least one time and many fields were sprayed multiple times, even behind a seed treatment. Until now, thiamethoxam (Cruiser, Avicta, or Acceleron N) has been impacted more than imidacloprid (Gaucho, Aeris, or Acceleron FI). . . . → Read More: Thrips Management in Cotton
The soybean crop ranges from still in the bag to around V5 stage on average across Mississippi. Over the last 10 days I have received numerous calls (mostly from Delta region) about bollworms attacking vegetative stage soybeans. Arkansas has also reported high numbers of bollworms in soybeans. In fact, AR has some fields where bollworms are infesting emerging soybeans in the crook stage and eating them to the ground where vegetation was present during planting. . . . → Read More: Bollworms Plentiful in Young Soybeans
Over the last few days I have had several reports of true armyworms showing up in wheat. Most of the calls I have received so far have been numerous worms at the ground level starting to defoliate up the plant but head clipping has been very minimal. Once wheat reaches the dough stage it is very difficult to show any yield benefits from treating armyworms in the absence of head clipping simply from defoliation. However, we have numerous fields that are still in the milk stage and susceptible. . . . → Read More: Armyworms Showing Up In Wheat
The dates for the 2014 Scout Schools have now been set. We will be providing detailed information on identification, biology, thresholds, and management of the major insect and disease pest of Mississippi row crops. These trainings can also be used to renew your insect and disease consultants license and CEU’s for Certified Crop Advisors will be provided at each. The meetings will also serve as In-Service training opportunities for MSU-ES agents as well. These trainings are great for the experienced and the inexperienced. . . . → Read More: 2014 Insect and Disease Scout School Dates Set
Our pheromone traps were monitored for the first time this week. Bollworm catches were high for this time of year with an average of 46 moths/trap caught in Noxubee county, 40 moths/trap in Lowndes county and 13 moths/trap in Oktibbeha county. Given that Angus Catchot is already receiving calls about bollworms in corn, it looks like we may . . . → Read More: Pheromone Trap Counts, May 8, 2014
We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met. . . . → Read More: New Neonicotinoid Pollinator Protection Labels
