Soybean loopers are starting to show up in high numbers in many areas of the state. In many cases, soybeans are past the point where yield loss can occur, but there are many later planted soybeans that need to be protected for a while longer. Below are a few tips on when to treat and what to treat with. . . . → Read More: Soybean Loopers Showing up in Late Soybeans:
We have had numerous calls over the last couple weeks about small, 2-5 day old larvae, under bloom tags in Bt cotton that is near, at, or beyond cutout. All of the research done to this point suggests that cotton is safe from bollworm damage when it reaches node above white flower 5 plus 300 heat units. . . . → Read More: When to Terminate Bollworm Sprays in Late Season Bt Cotton
Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower . . . → Read More: Insect Trap Counts, August 29, 2014
This week’s bollworm trap catches were similar to slightly higher than last week, while tobacco budworm trap catches fell slightly for the week. The trap catches are typical for this time of year, so expect moderate worm pressure in all . . . → Read More: Insect Trap Counts, August 22, 2014
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
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
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
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
