Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

🕔18:28, 31.Aug 2014

Phytotoxicity, associated with the application of some specific foliar fungicide products, has been observed in numerous commercial soybean fields again this season. Keep in mind that the symptoms associated with fungicide phytotoxicity will appear quite similar to sudden death syndrome (SDS). However, SDS only occurs in light soil classes. When scouting fields, keep in mind that an entire field with SDS-like symptoms might be the result of fungicide phytotoxicity, thus not a disease after all.

When to Terminate Bollworm Sprays in Late Season Bt Cotton

🕔16:00, 29.Aug 2014

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.

Diseases of soybean continue to be observed throughout the MS production system. At present, soybean rust has not been detected within MS; however, we continue to scout for the presence of rust, as well as additional diseases of economic importance throughout sentinel plots as well as commercial soybean fields. Frogeye leaf spot, sudden death syndrome, stem canker, and aerial blight continue to be hot topics for most soybean farmers.

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.

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.
