Southern Corn rust is EARLY this year and has been found in Seminole, Wayne and Pierce Counties. Protecting corn approaching or beyond tassel with a fungicide is an important consideration. Once corn reaches the dough stage it is safe. Most likely, Southern Rust is in other area counties and possibly already in fields in Appling County. <\/span><\/p>\n For corn with good yield potential it is advised to apply a fungicide at the tassel stage. Southern Rust can significantly reduce yields if left untreated. Triazole fungicides (tebuconazole) and strobilurin fungicides (pyraclostrobin, azoxystrobin, and others) all have good activity against southern corn rust. Triazoles will have greater systemic activity and strobilurins will have a longer protective window. <\/span><\/p>\n Asian Soybean Rust<\/strong><\/p>\n Asian soybean rust is in Florida and Alabama. That’s close enough proximity to Georgia that there is no doubt that our soybean crop will be affected this year. A fungicide is recommended between flowering and early pod development which is about the same time that Boron and Dimilin applications will be made.<\/p>\n Propiconazole and Phosphorous Acid\u00a0Fungicides in Peanut<\/strong><\/p>\n It’s getting about time for fungicide sprays to begin in peanut fields. Some earlier planted fields have already reached the starting date. You probably have heard by now that the European Union has questioned residue studies on propiconazole (active ingredient in products like Tilt and also a component of Artisan) specifically on peanut.\u00a0 This lead Syngenta Crop Protection to announce it will not sell Tilt\/Bravo for the peanut market in 2016.\u00a0 Companies like Golden Peanut and Birdsong have notified growers not to use products containing propiconazole that will be sold to them. The European Union has also raised questions about residues with phosphite fungicides.\u00a0 Phosphite\/phosphorous acid fungicides (like K-PHITE and ProPhyt) have been used in Georgia recently for management of Pythium pod rot, a disease that can be especially difficulty to control.\u00a0 Like peanuts treated with propiconazole, peanuts treated with phosphite-fungicides may also be rejected by the European Union. This may or may not affect you, but if it does here are recommendations from Dr. Kemerait:<\/p>\n Don’t slack on weed control!<\/b><\/p>\n One thing we’ve constantly preached is NEVER PLANT INTO EMERGED PIGWEED. NEVER is pretty clear. That means NEVER. It doesn’t matter what variety or what herbicide you can use…..NEVER plant into pigweed. If you do, you will already be starting off behind and guaranteeing\u00a0that you will have to hand pull weeds.<\/p>\n Where I see the most problems is on ripped and bedded land. The land is prepared and then left with no pre herbicide. Pigweed germinate between land prep and planting time. When the tractor and planter get to the field it knocks the top of the bed off, plants the seed and buries the pigweed. That doesn’t kill the pigweed.<\/span><\/p>\n Don’t start off behind. Whether you are strip tilling\u00a0or bedding land, you must start clean in a field BEFORE planting.<\/p>\n Liberty herbicide will be the backbone of our cotton herbicide program even with 2,4-D and Dicamba. We must protect Liberty. Spraying pigweed that are too large, not being timely and\/or reducing rates will build resistance over time. This is what caused the resistance to glyphosate.\u00a0Never reduce the labeled rate of Liberty and be timely when applying the herbicide. Remember: Yes, Liberty may kill a much larger pigweed than labeled, but at one time, so did glyphosate.<\/p>\n Peanut Germination<\/strong><\/p>\n I’ve seen a few peanut\u00a0fields with some strange germination happening. The field in the below pictures was planted May 25. The pictures were taken on June 14. Nearly 3 weeks after planting there’s still peanuts cracking and some that died before cracking. There’s a couple of possibilities for this. The most likely cause is\u00a0weather related. Having enough moisture to get the seed to germinate at planting, followed by hot dry weather, followed by rain and then more\u00a0hot dry weather\u00a0can\u00a0cause shock on the young seedling plants. Sometimes herbicides\u00a0or seedling disease can also be an issue, but most likely we’re dealing with environmental stress.<\/p>\n Tomato Spotted Wilt Virus<\/b><\/p>\n This has been one of the worst years we’ve seen in a while for TSWV. Thrips pressure was really high mainly due to our warm winter. Thrips had plenty of weeds to feed on during the winter and the population continued to increase as spring and summer arrived. In my tobacco TSWV trial the worst time for infection was May 12-25. Tomatoes, peppers and in some fields peanuts have been hit hard with TSWV.<\/p>\n Upcoming Dates:<\/strong><\/p>\n The GA\/FL Tobacco Tour<\/strong> will make a stop in Appling County Wednesday June 15 at Jared and Danny Turner’s field off Hwy 121 at 11:45 am. We will be looking at a released variety research trial.<\/p>\n Soil Health Workshop June 21, 2016 8:30 am<\/strong><\/p>\n The Georgia Conservation Tillage Alliance\u00a0will be partnering with the Coastal Georgia RC&D Council on a soil health workshop and conservation tillage field day.\u00a0\u00a0 This event will be held at the farm of Joey Norman at Glenville, Georgia. The afternoon session will be at\u00a0the farm of Clayton Anderson, located\u00a0in Register, Georgia. To sign up\u00a0call Dianne Beasley at 912-459-2070<\/p>\n Southeast Georgia\u00a0Pecan Field Day will be August 17<\/strong><\/p>\n A New Tool<\/strong><\/p>\n You can go to https:\/\/www.eddmaps.org\/ipm\/<\/a> and view what other Extension Agents and Specialists\u00a0are reporting across Georgia. The EDDMapS IPM helps coordinate information from different sources to provide a clearer picture of current pest and disease activity, distribute that information and\u00a0to help people make better pest management decisions.<\/p>\n Research Trials<\/b><\/p>\n Over the past couple of months I’ve been getting a lot of research trials planted. The last row crop trial\u00a0was planted Friday June 3rd. If you would like to visit any of these trials please give me a call and I’ll be glad to show you.<\/p>\n 2016 Research Trials:<\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Southern Corn Rust Southern Corn rust is EARLY this year and has been found in Seminole, Wayne and Pierce Counties.
