Insecticide Seed Treatments in Soybeans Updated

🕔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.

Fall Armyworms in Mississippi Crops Updated

🕔19:17, 3.Aug 2012

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.

Fall Armyworms in Soybeans and Peanuts Updated

🕔05:28, 29.Jun 2012

We have gotten multiple calls over the last week about fall armyworms in soybeans and peanuts. In every case, it has been a situation where people got behind on grass control when we were getting a lot of rain a couple weeks ago. In those situations, they have sprayed the grass during the last two weeks with products such as Select or Roundup that are relatively slow acting. A lot of the grass is infested with grass-strain fall armyworm and big worms start moving over into the crop about a week to ten days after the application when the grass starts to die.

Thrips in Peanuts and Their Impact on Tomato Spotted Wilt Virus (TSWV) Updated

🕔11:14, 4.May 2012

There have been a lot of questions recently about thrips control in peanuts. In general, thrips will not hurt peanut yields except in EXTREME situations.

Foliar insecticide applications, though rarely needed, should be based on plant injury rather than thrips numbers.
