The Georgia Dept. of Agriculture will host a Pesticide Waste Collection (Clean Day) event on September 30, 2106 at the Cordele State Farmers Market in Crisp County from 9:00am to 3:00pm. The Georgia Department of Agriculture is excited to have the funding to support this excellent program as a benefit to all Georgia citizens and the environment. The collection day is open to all who would like to participate. Due to collection limits, pre-registration is required and must be completed by September 26, 2016. Additional information and registration forms can be found online at http://agr.georgia.gov/georgia-clean-day.aspx
Don’t leave pesticide waste sitting around in storage waiting for an accident or spill to happen, take advantage of this rare opportunity to dispose of pesticide waste safely and responsibly.
They are indeed back. You have probably already seen Japanese Beetles (Popillia japonica) in your landscape. They enjoy munching the leaves of roses, maple trees, cherry trees, peaches and grapes. They actually are a pest to over 300 plant species. A single beetle doesn’t do much damage. Unfortunately once a beetle finds a food source other beetles soon follow. It is the groups of beetles that do real damage.
Japanese beetles first arrived in the United States around 1917. As with many non-native species, in their home country of Japan they are not a major problem. This pest causes damage in the adult beetle stage as well as the larval stage. The larvae, or grubs, live in the soil and can do damage to plant roots.
We often get questions from gardeners about these pests and thought it might be helpful to share them with you:
Do you need to worry about this pest?
The Japanese Beetle season lasts 4-6 weeks, so realize they won’t be around for very long. They are not a major pest of vegetable gardens and generally eat the leave margins leaving a lacy-type leaf. They sometimes also eat petals and can damage fruit.
Do the Beetle Traps Work?
Yes, the beetle traps do work by attracting beetles from all over your area and bringing them to your yard! The traps contain a pheromone, a sex attractant, that can attract beetles that may not have visited your garden on their own.
If you decide to use traps, do not put them in the middle of your garden as you would just be bringing in additional numbers of the pests. Also, the traps will need to be emptied often. The dead beetles give off an ammonia scent that will repel other beetles.
Wouldn’t it be nice if your neighbors put out traps to attract your beetles to their yards?
Is Their a Non-Chemical Control?
Most home or community gardeners can control Japanese Beetles by simply picking the insects off the plants and dropping them in a container of soapy water. By regularly scouting for these insects and removing them, you will prevent any real damage. This is a great job for kids.
What if I Decide I Need an Insecticide?
There are insecticides available to kill Japanese Beetles but realize that the chemicals don’t affect just those beetles but possibly beneficial insects as well. Contact your local UGA Extension Agent for a specific chemical recommendation. As with all pesticides you will want to follow the label directions to the letter.
Following a late winter or early spring pruning of Maple, Birch, Elm, or Grapevines it is common to observe “bleeding” from the pruning wounds. This phenomenon usually occurs just before and during leaf emergence in the spring, especially during years of abundant soil moisture. The temporary bleeding is generally not detrimental to the health of the plant and primarily consists of a watery sap solution. The bleeding usually ceases once the leaves have fully emerged and water begins to evaporate through the leaf stomata, creating transpirational pull that overshadows the root pressure.
The upward flow of water is caused by osmotic pressure in the root system that begins with the imbalance of water molecules between the soil and the root system. A high concentration of minerals and carbohydrates in the root system generally translates to a lower concentration of water molecules when compared to the surrounding soil. Water molecules enter the root cells to equalize distribution, causing root cells to become turgid and force water upwards in the vascular system. (Incidentally, the reverse is true when too much fertilizer is applied and a higher concentration of minerals in the soil prevents the osmotic absorption of water into the root system.)
Occasionally, bleeding can be a nuisance where these plants drip on parked cars and pedestrian spaces. In such cases, delay pruning of these species until late spring-early summer to help to reduce the issue.
If prolonged bleeding occurs and you observe any unusual signs or symptoms of pests or disease, report the information to your local extension agent for further assessment.
The Urban Ag Council, a professional organization representing the Georgia landscape industry, reports that members are experiencing an uptick in equipment theft at worksites, offices, and storage facilities. To address the issue, the UAC is summoning a “call to action” from all landscape companies and compiling data from those who have experienced recent or past theft (2014-2016). Armed with this data, the UAC hopes to meet with law enforcement agencies, equipment manufacturers and suppliers to determine a course of action to reduce these losses.
Here are some general equipment theft prevention strategies to consider:
1. Train employees on company procedures to deter equipment theft. In addition, discuss what to do in the event of a theft or robbery.
2. Take Inventory: Establish a routine of equipment inventory. Keep documentation and photo records of serial numbers, makes, and models of equipment.
3. Parking strategy: Be strategic about where you park your vehicle on each jobsite or lunch destination. Park in well lighted locations visible to the work crew and avoid leaving equipment unattended in back lots or hidden areas that are conducive to theft. Position trailers so they aren’t easily accessed or swapped to another vehicle.
4. Deterrents: Lock vehicles, trailers, trailer tongues, and secure equipment when unattended. Don’t leave keys in trucks or commercial mowers.
5. Tracking Devices: Install tracking devices on large equipment.
6. Be Alert: Pay attention to suspicious activity.
7. Insurance: Review your policy and ask your insurance provider about theft prevention.
Blueberries are a perennial shrub that is relatively easy to grow. Rabbiteye types are popular statewide and their fruit is delicious! You may have read in agricultural science articles about “chill hours.” What are they? Why do they matter? To answer those questions we are going to turn to science so, please pardon the charts!
According to UGA scientists Gerard Krewer and D. Scott NeSmith (Blueberry Cultivars of Georgia) blueberries require a certain number of chill hours each winter to produce the optimum fruit harvest. Chill hours are the number of hours of winter temperatures 45 degrees F and below. If blueberry plants do not receive the adequate amount of chilling, bloom and leaf development can be late and erratic. This can result in a lackluster harvest. To sum it up – blueberries have to have some cold winter weather.
400 to 450 hours
350 to 400 hours
600 to 700 hours
550 to 650 hours
500 to 550 hours
How do we know how many chill hours we have had in our area? The weather stations of georgiaweather.net have chilling hours calculators. As of February 22nd:
Number of Chill Hours between Oct 1, 2015 and February 22, 2016
So what does this all mean? As noncommercial blueberry growers, it can give us some scientific information about our blueberry harvest and it gives us some insight into plant biology. It also gives us another reason to watch the weather forecast and welcome cold winter weather.
If you don’t grow blueberries yet, give it a try! See Home Garden Blueberries for more information. Also contact your local UGA Extension office. Many of them have plant sales this time of year and blueberries are often for sale.

Because of real concerns about our pollinator population the Environmental Protection Agency (EPA) asked each state to develop a customized pollinator protection plan with recommendations on improving pollinator health. This is not a regulatory document but just guidelines to help our pollinators.
Georgia’s plan is finished! Protecting Georgia’s Pollinators (PGP) was developed as a joint effort between UGA’s Department of Entomology and the Georgia Department of Agriculture. The author committee is made up of Jennifer Berry, Kris Braman, Keith Delaplane, Mike Evans, Philip Roberts, and Alton Sparks. Those of you who are beekeepers may recognize several of these names as people heavily involved in pollinator research.
The draft of the plan was sent to over 35 groups across the state for their input – Georgia Beekeepers Association, Georgia Fruit and Vegetable Growers Association, the Peach Commission, the Blueberry Commission to name a few. The result is a plan that has a role for all of Georgia’s citizens.
As community and school gardeners we have a vested interest in pollinator health. More pollinators means more food from our gardens. Not to mention the beauty of enjoying the insects at work.
Guidelines from the pollinator plan that we can garden by include:
If possible leave areas of your property permanently undisturbed for soil-nesting bees. Sun-drenched patches of bare soil, roadsides, ditch banks, and woodland edges are prime bee habitats.
Dedicate pollinator habitat spaces in your garden.UGA’s Pollinator Spaces Project has many resources to help with this. Bees need a season-long unbroken succession of bloom. Many plant species bloom in the spring. Remember to plant plants to bloom in mid- to late-summer including Vitex, sages, and sunflowers. Your local UGA Extension office will have information on what pollinator plants grow well in your area.
Know the beekeepers in your area. If your garden has a bee hive you want to be very careful about pesticide application and you will want to review in detail the section on pesticide users in the plan.
Consider increasing bee nesting sites by providing bee homes. These consist of solid wood pre-drilled with 1/4 to 1/2 inch holes that are at least 3-inches deep. It is important that the tunnels terminate in dead-ends. These are easy to create and a nice addition to any garden.
Educate your gardeners about insect behavior. For example, the flight and nesting behavior of certain solitary bees happens in bursts of extreme activity. In the spring or summer you may see a large number of bees flying out of tunnels in the grass over your garden all at once. These are solitary bees and they are gentle, and their sting risk is extremely low! Enjoy watching them!
If you think insects are a problem in your garden take steps to correctly identify the insects and determine, with the help of your UGA Cooperative Extension Agent, if remedial action is necessary.
If your garden is located in a park or other public space that is maintained by local landscape crews, make sure that if they need to apply insecticide for turf pests that they mow the grass immediately before applying the pesticide. The mowing will get rid of weed flowers that may attract bees.
Follow all pesticide label directions and precautionary statements. THIS IS THE LAW. EPA is now requiring a “Protection of Pollinators” advisory box on certain pesticides labels. Look for the bee hazard icon and instructions for protecting bees and other pollinators.
Take some time to look at Protecting Georgia’s Pollinators and you will see we all have a role to play. If you need any information about the plan or protecting pollinators contact your local UGA Cooperative Extension Agent.
