Bean Leaf Beetle Numbers Picking Up in Mississippi Soybeans

BLB_pod_feeding

Bean leaf beetle numbers have been increasing steadily over the last couple weeks. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding. Bean leaf beetles were once very easily controlled by very low rates of pyrethroid . . . → Read More: Bean Leaf Beetle Numbers Picking Up in Mississippi Soybeans

Terminating Insect Sprays in Mississippi Soybeans

DSC_0216

We are quickly approaching that time of year where some of the earlier planted fields are turning color and others are approaching R6 vey quickly. Often times many of the insect pest we deal with “pile in” about this time and growers face the tough decision to treat when it may not pay back or try and race them to the end. We have devoted a lot of time and effort in recent years to evaluate and validate thresholds in soybeans under the current growing practices in Mississippi. Through these research efforts we have made several changes to insect thresholds and termination points for insect pest of soybeans in MS. . . . → Read More: Terminating Insect Sprays in Mississippi Soybeans

Bollworms in Dual Gene Bt Cotton: Control and Expectations

DSC_0056

Over the last 7 days we have had numerous reports of high bollworm numbers in some BollGard II, TwinLink, and WideStrike fields in the Mississippi Delta. We have seen fields in the past that reach treatable levels but some reports are much higher than we have seen in recent years. At this time there does not appear to be any specific varieties that are adversely affected more than others. It appears to be a function of high pressure in isolated areas at this time. . . . → Read More: Bollworms in Dual Gene Bt Cotton: Control and Expectations

Transform Section 18 Amendment Allows 3rd Application to Sorghum

WSA5

White sugarcane aphid continues to be a serious problem in grain sorghum fields across Mississippi and the Mid-South. Because this is a brand new pest, there are many questions still unanswered. The Mid-South Entomology Working Group is frantically working on this issue to provide answers. At this time Transform insecticide is the only product providing acceptable . . . → Read More: Transform Section 18 Amendment Allows 3rd Application to Sorghum

White Sugarcane Aphid Update – 8/1/2014

White sugarcane aphid infestations are increasing across the state and more applications are going out to manage this pest. Over the last week to 10 days we have heard about numerous fields that have received a second application. Remember, that the Section 18 label for Transform states that no more than 2 applications can be made in a field. . . . → Read More: White Sugarcane Aphid Update – 8/1/2014

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

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
