Armyworms in Rice Updated

🕔10:39, 23.May 2014

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.

Should You Ever Treat Thrips in Soybeans? Updated

🕔10:10, 21.May 2014

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.

Thrips Management in Cotton

Thrips Management in Cotton Updated

🕔14:44, 16.May 2014

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).

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.

Armyworms Showing Up In Wheat Updated

🕔09:45, 14.May 2014

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.
