Terminating Insect Sprays in Mississippi Soybeans

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

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 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.
