Tarnished Plant Bug Nymphs Showing Up in Pre-Bloom Cotton

Tarnished Plant Bug Nymphs Showing Up in Pre-Bloom Cotton

🕔08:29, 11.Jun 2014

The tarnished plant bug calls have started to come in on small cotton already. In some cases, consultants and growers are finding nymphs on very young cotton with only 1-2 squares. Similarly, some are reporting plant bug flagged terminals in pre-square cotton. We rarely have to spray pre-square cotton for plant bugs, but our threshold is 1 flagged plant per 10 row feet with bugs present. Although tarnished plant bugs are our most important and most consistent pest of cotton in the Delta, we usually don’t start finding nymphs until closer to first flower.

Influence of Rainfall on Insecticide Efficacy

🕔13:29, 2.Jun 2014

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.

Mixing Thrips Insecticides With Post Herbicides: Yes or No?

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.

Slugs – A Persistent Problem in Cool Years

🕔09:05, 21.May 2014

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.

Thrips Management in Cotton

Thrips Management in Cotton

🕔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).

Bollworms Plentiful in Young Soybeans

Bollworms Plentiful in Young Soybeans

🕔11:48, 16.May 2014

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.

Armyworms Showing Up In Wheat

🕔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.

New Neonicotinoid Pollinator Protection Labels

🕔17:03, 1.May 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.

Calibrating Insecticides in Row Crops

🕔12:00, 20.Mar 2014

I have gotten numerous question about calibration of in-furrow rigs this year, so I am republishing an article I put up in the past that breaks calibrating pesticides down to a very easy understandable level. Proper calibration can mean the difference in control or failure of a product against the targeted pests and potentially thousands of dollars of savings to the grower.
