Commonly referred to as spotted lanternfly (SLF), this insect is native to China, India... Read More

Please take a look at this information... Read More

San Jose Scale and Mites Update: San Jose scale has been a little quiet this year…almost too quiet. This heatwave has probably slowed their development down a little bit, so I am anticipating seeing an increase in activity soon. This timing may be particularly important for blocks that have had a history of scale problems. Looking at the degree day timing... Read More

Pecan Insects and Heat: With the very high temperatures this week and last, there is no point in spraying for insects when the temps are in the 95+ range. Extreme heat slows and then stops reproduction in insects like mites and aphids and will shorten the life span (kill) when it gets up near 100. Materials that rely on leaf uptake are affected because the leaf seals... Read More

Folia Sulfur Sprays Under High Temps: Foliar Sulfur sprays applied in June and July have been shown to provide several benefits for pecan production, including suppression of mite populations and an increase in nut size. Sulfur may also aid in the suppression of some minor foliar diseases, and there is some evidence that it may aid in scab suppression on... Read More

Nut Curculio: You may notice some nut drop in your orchards at this time. This can occur for a number of reasons, including rainfall after a long hot, dry period and natural drop on certain varieties. One thing we are seeing at the moment is drop from nut curculio. The damage from nut curculio is very conspicuous. Nuts will have a “tobacco-juice” stain on the outside of the... Read More

Citrus Canker Confirmed in GA: On June 14th, 2022, the Georgia Department of Agriculture (GDA) announced that citrus canker has been confirmed within a commercial citrus grove in Decatur County, Georgia. This bacterial disease, which is subject to USDA-APHIS quarantine regulations, is widespread within Florida, and has also been found... Read More

Cotton Foliar Disease Considerations: Target spot and areolate mildew will not occur in every cotton field in Georgia every year. When they do occur “early enough”, repeated research trials have shown that a) significant yield loss can occur due to these diseases and that b) timely fungicide applications can protect against, but not eliminate, yield… Read More

Stinkbug Mgmt in Cotton:
Southern green and brown stink bugs are the two most common stink bugs infesting Georgia cotton. Based on stink bug populations in corn and reports of early planted cotton, stink bugs are likely to require management in many fields. Stink bugs have sucking mouthparts and prefer to feed on developing seeds in medium sized bolls… Read More

Diuron Update and Weeds in Cotton: For years, we have been discussing how science suggests that goosegrass populations are likely to explode in cotton systems that are heavily dependent on Liberty or dicamba, especially when residual herbicides are not used wisely. This year it seems that science is proving to be correct with goosegrass issues more prevalent across… Read More

Scout for Lesser Cornstalk Borer in Peanut: Regardless of whatever else has to be done on the farm in South Georgia, one thing that needs to happen is scouting peanut fields for lesser cornstalk borer (LCB). This insect is the most damaging pest of peanut in Georgia; it feeds on stems, pegs, and pods, and it will reduce yield and increase the risk of aflatoxin… Read More

It's Japanese Beetle Season: The time is upon us once again. Japanese beetles are showing up in vineyards around the state. In large enough numbers, Japanese beetles can be a severe pest of grapes during the summer, feeding mainly on foliage and (thankfully) rarely on the berries. More problematic is Japanese beetles feeding on new plantings. Older… Read More

Preparations for Grape Root Borer: If you are unfamiliar with grape root borer, GRB is a clearwing moth with larvae that tunnel into the larger roots and crown of grape vines and feed below the soil surface. Symptoms of infested vines include poor growth and fruit set, and potentially complete root girdling and vine death. As such, grape root borer is a significantly… Read More

July Weather & Climate Outlook: In the month of June, drought increased across Georgia significantly, going from just 9% at the end of May to 54% by the end of the month. Many of you have told me you think even that is an underestimate of how bad things are. One of the problems with the Drought Monitor’s depiction of drought is that… Read More

Controlling Poison Ivy in the Landscape
Poison ivy (Rhus radicans) is a common poisonous plant in Georgia. The American Medical Association estimates that in the United States poison ivy and Pacific poison oak (Rhus diversiloba) cause more cases of contact dermatitis than all other plants and household and industrial chemicals combined. Every person who works outdoors with plants or participates in hiking, camping or other outdoor activities should be able to identify poison ivy. Failure to do so can lead to severe allergic reactions. Circular 867-10
