Influence of Rainfall on Insecticide Efficacy

Every year at some point during the season we seem to hit a rainy spell where it seems to rain at some point every day and we have showers widely scattered across the state. It started raining last Wednesday and we have had some rain everyday since then and it is currently raining in Stoneville right now (Monday morning). With that, the questions start about how long you need to spray before a rain to get acceptable control. . . . → Read More: Influence of Rainfall on Insecticide Efficacy

Delta Research and Extension Center’s Agronomic Crops Field Day, June 17, 2014

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

Armyworms in Rice

Similar to most years when we have armyworms in wheat, there is the threat of having armyworms in seedling rice. We know of at least one rice field in Mississippi that was sprayed earlier this week. In general, damage from armyworms will not impact rice yields at this time of year unless they are beginning to reduce plant stand. This is especially true in hybrid rice planted at low seeding rates. . . . → Read More: Armyworms in Rice

Should You Ever Treat Thrips in Soybeans?

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?

Slugs – A Persistent Problem in Cool Years

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

Thrips Management in Cotton

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

Bollworms Plentiful in Young Soybeans

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

Insecticide Seed Treatments and Rice Water Weevil Management in Rice

A little rice has started to go to flood in Mississippi this week and that means it is time to start thinking about rice water weevil. Overall, the majority of the crop is behind because of all of the rain that we have had across the Delta over the last several weeks. In general, the rice that is currently being flooded was some of the earliest planted. As a result, the early rice has endured a lot of rainfall and adverse conditions. . . . → Read More: Insecticide Seed Treatments and Rice Water Weevil Management in Rice

New Neonicotinoid Pollinator Protection Labels

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

Start Planning Plant Bug Management Now

Although very little, if any, cotton has been planted in the Delta, it is not too early to start thinking about managing tarnished plant bugs. . . . → Read More: Start Planning Plant Bug Management Now
