Insect Trap Counts, July 25, 2014

Bollworm counts remain at fairly high levels again this week for the second week in a row, so vulnerable crops likely have many eggs and small larvae. Tobacco budworm counts remain low, so worms found will generally be bollworms. Southwestern corn borer trap counts  were still fairly high in the most northern counties of the state, but . . . → Read More: Insect Trap Counts, July 25, 2014

Managing Cotton Aphids in 2014

We had a few calls over the last week about poor control of cotton aphid with Transform. In all of those cases, the field was actually sprayed for plant bugs with a 1.5 oz rate of Transform. That rate should be very effective on cotton aphid based on previous experience. As a result, we collected aphids from three different fields this week to test their susceptibility to Transform. . . . → Read More: Managing Cotton Aphids in 2014

White Sugarcane Aphid Update: 7/25/2014

Over the past week we have had numerous opportunities to further observe spread and control of fields infested with white sugarcane aphids. We also have managed to get a couple of replicated small plot test out. Below are a couple bullet points based on recent experiences from walking numerous fields and talking to numerous folks around the state and Mid-South. . . . → Read More: White Sugarcane Aphid Update: 7/25/2014

Rice Stink Bugs in Mississippi Rice

As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations. . . . → Read More: Rice Stink Bugs in Mississippi Rice

Trap Counts, July 18, 2014

Bollworm moth counts were up sharply across the state this week, so higher bollworm larval pressure should be expected over the next 1-2 weeks. Southwestern corn borer counts were high in Quitman, Tallahatchie and Leflore counties, but low elsewhere. Most corn is past the vulnerable window, so only late-planted corn that has not reached dough stage should . . . → Read More: Trap Counts, July 18, 2014

Treating White Sugarcane Aphid: Decision Aid

wsca leaf

White sugarcane aphids (WSCA) have been blowing up quickly to treatable levels in several counties in Mississippi. Over the last few days here have been several field requiring treatments likely with more coming. Because this is a new pests for Mississippi, we have been following the lead of our colleagues in Texas and Louisiana who dealt with this in 2013. Below are some criteria that we put together based on what we know to date that will help in making a decision to treat WSCA. . . . → Read More: Treating White Sugarcane Aphid: Decision Aid

White Sugarcane Aphid Update and Impact on Midge Applications

Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha. . . . → Read More: White Sugarcane Aphid Update and Impact on Midge Applications

Management of Kudzu Bugs in Mississippi Soybeans

kudzu bug nymphs

By now most folks have heard of Kudzu bugs. In fact, we have now confirmed them in 52 counties in Mississippi. Kudzu bugs, Megacopta cribraria, was first found in Georgia in 2009. Since that time it has spread rapidly across the southeast kudzu bug map 7_8and is now moving west in to Mid-southern states. It was first found in Mississippi in 2012 and now covers most of the state. . . . → Read More: Management of Kudzu Bugs in Mississippi Soybeans

Insect Trap Catches, July 3, 2014

Bollworm catches were similar to the previous week while tobacco budworm counts continue to slowly rise. Neither is particularly high for this time of year. Southwestern corn borer counts were up sharply this week, with a few traps in the Delta above treatment thresholds for non-Bt corn. However, no county average was greater than 100 moths/trap, so . . . → Read More: Insect Trap Catches, July 3, 2014

Assessing Control of Tarnished Plant Bug in Prebloom Cotton

Tarnished plant bug numbers have actually started off at low to moderate levels this year in the Delta region but just in the last few days numbers seem to be picking up pretty good in a few locations and square retention is not optimal. I have mentioned on numerous occasions the inability to adequately access product . . . → Read More: Assessing Control of Tarnished Plant Bug in Prebloom Cotton
