Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases. . . . → Read More: Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

Not all Boll Rots are caused by Bacterial Blight

Boll rot as a result of Fusarium (as indicated by the pink growth of fungal structures on the boll).

Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders. . . . → Read More: Not all Boll Rots are caused by Bacterial Blight

Soybean Loopers Showing up in Late Soybeans:

loopdef3

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:

When to Terminate Bollworm Sprays in Late Season Bt Cotton

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

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
