Mississippi Kudzu Bug Update: 7/12/2013

Mississippi Kudzu Bug Update: 7/12/2013

🕔13:25, 12.Jul 2013

I have had numerous calls on kudzu bugs in the last couple weeks, mainly from the southwest part of the state. Kudzu bugs were found in 4 counties in 2012 in MS. In 2013 we have now confirmed 10 additional counties, in which 6 were found in soybeans. Since these initial finds in soybeans in Warren, Claiborne, Hinds, Yazoo, Stone, and Rankin Counties, it has become common for consultants to find 4-8 adults per 25 sweeps, in a few cases up to 10-15 in a couple of these areas.

Managing Insect Pest in Mississippi Grain Sorghum

🕔10:06, 9.Jul 2013

Mississippi traditionally does not plant a lot of grain sorghum compared to some states but the acres we plant (42K according to USDA, 2013) have to be scouted and managed for insect pest at least weekly. Grain sorghum in Mississippi can have significant insect issues in some years, especially on late plantings.

Thrips Pressure Heavy Despite a Late Planted Crop

🕔08:37, 1.Jun 2013

No doubt this is a very late planted crop by Mississippi standards, so I was a little surprised when numerous thrips calls started coming in about a week or so ago. Usually thrips issues are much worse on cotton that is growing off slow due to cold weather or any number of issues that may slow growth.

How will rainfall impact seed treatments in soybeans, rice, cotton, and other crops?

How will rainfall impact seed treatments in soybeans, rice, cotton, and other crops?

🕔19:54, 24.May 2013

With all of the rainfall that we have had around most of the state, there have been a lot of questions about the impact on seed treatments. In general, most of the seed treatments that are being used in all crops are water soluble. Typical levels of rainfall should not have a negative impact on the efficacy of seed treatments, but excessive rainfall may.

Aphids in Rice

🕔08:46, 24.May 2013

There have been some reports of aphids in Arkansas rice fields recently. I talked to Gus Lorenz (UofA Extension Entomologist) yesterday and he told me that they are seeing several species of aphids scattered throughout Arkansas. I have not heard of or seen any in Mississippi rice fields to date, but I wanted to make everyone aware of what is being seen in Arkansas.

Will cold and rainy weather impact seed treatments in corn and rice?

🕔16:38, 5.Apr 2013

This is an important question right now with the weather conditions that we have had over the last few weeks. A considerable amount of corn and a little bit of rice has been planted over the last 3 to 4 weeks. In most of those fields, the crop has either just emerged or has not emerged yet.

Insecticide Seed Treatments in Soybeans

Insecticide Seed Treatments in Soybeans

🕔14:53, 13.Mar 2013

What is the importance of a neonicotinoid insecticide seed treatment in soybeans? Basically it is a risk management tool. Soybean seedlings have a tremendous amount of vigor and can tolerate a substantial amount of insect injury. However, early planted soybeans can encounter less than optimal environmental conditions which can stress plants and reduce vigor. Insect injury under these conditions is an additional stress. During 2010, it is estimated that the use of insecticide seed treatments in soybeans resulted in a value of $28.8 million to Mississippi soybean growers.

Terminating Spider Mite Applications in Cotton

Terminating Spider Mite Applications in Cotton

🕔10:23, 11.Aug 2012

When to terminate spider mite treatments can be a very difficult decision this time of year. Spider mites can cause yield loss directly by feeding on small squares and bolls causing them to abort, or indirectly by feeding on leaves which reduces photosynthesis not allowing bolls to fill out correctly. In many ways this indirect damage would be very similar to defoliation.

Fall armyworm can be a challenging pest to find and an even more challenging pest to manage in some crops. The damage that they cause and their management varies greatly from crop to crop. The reason for this is due to their preferred feeding sites on different crops and the presence of host strains.
