On a site visit this week I saw some trees that had mite populations that were higher than what I would expect this time of year. They turned out to be citrus red mites and luckily they are pretty easily controlled. At one time the citrus red mite was a serious pest in Florida, but now it is less of an issue. These mites are less than five tenths of a centimeter in length with the females being larger than the males. Females lay up to 37 eggs in two weeks and live about 23 days. However, high temperatures and high humidity reduce the growth of populations. When populations are higher, from November to June, they cause a stippled look on leaves. This can cause heavy leaf drop and limb dieback in the most severe infestations. When trees are dormant mites can be controlled with a dormant oil and once this is no longer an option there are several other insecticides that are.
AUXIN TRAINING REQUIREMENTS: GEORGIA 2019
NOTICE! U.S. EPA-Industry mandated label changes to dicamba products Engenia,
FeXapan, and XtendiMax are now effective for the 2019 growing season.
Engenia, FeXapan, XtendiMax
1. As mandated by federal labels, one must hold a private or commercial pesticide applicator license to purchase and use these restricted use herbicides. Use is limited to ONLY those persons holding a private or commercial applicator certification.* It is no longer permissible for non-certified applicators to apply these products under the direct supervision of the certified applicator.
2. Prior to applying these products in 2019, ALL applicators must be trained according to the federal labels. In Georgia, applicators must complete the 2019 Using Pesticides Wisely classroom training. If you attended this training in 2015, 2016, 2017, or 2018, you must re-take the training in 2019.
3. Industry applicator trainings are encouraged and beneficial; however, they will not fulfill Georgia’s requirement for auxin training.
4. Each label requires certified applicators to document application information. Forms have been designed to help with this challenge and can be found at your local UGA Extension office, from the herbicide registrant, or at http://www.agr.georgia.gov/24c.aspx
Enlist Duo or Enlist One
1. All persons in charge of in-crop applications (planting through harvest) of Enlist Duo or Enlist One in Enlist cotton or soybean must complete the Using Pesticides Wisely classroom training. If you attended this training in 2015, 2016, 2017 or 2018, you must re-take the training in 2019.
Documentation of UPW Training
Bring your pesticide license to the training if you have one. Attendee’s names will be placed on a list posted to the Georgia Department of Agriculture’s auxin website at http://www.agr.georgia.gov/24c.aspx. Please allow up to 21 days after the training date for names to be posted. This list will serve as the official training record and will provide verification of one’s attendance.
Obtaining a Pesticide License to Apply Engenia, FeXapan, XtendiMax Option 1: For those seeking certification as a private pesticide applicator: Initial certification to become a certified private pesticide applicator requires the completion of an interactive, online Private Applicator training program administered by University of Georgia Extension (http://extension.uga.edu/programs-services/pesticide-safety-education/private-applicators.html). The online training and testing requires a total time commitment of approximately 4-5 hours and a $25 fee. Applicants MUST be able to read and understand a label. Application of auxin herbicides carries certain inherent risks associated with off-target movement. Anyone applying them should be well-trained, have a clear understanding of the potential for off-site damage, and be able to make complex decisions on when and where these products should be applied. Applicants and their employers should carefully consider who is capable of applying these products safely before beginning the certification process. Option 2: For those seeking a 2-year certified applicator license to apply only Engenia, FeXapan, XtendiMax: At the conclusion of the UPW trainings noted on the first page, UGA Extension and the Department of Agriculture will provide a 45 minute training allowing attendees to obtain a limited product private applicators license for a period of 2 years. This limited certification will fulfill the label requirements for the restricted use products Engenia, FeXapan, and Xtendimax. Upon completion of this training, attendees will be authorized to apply Engenia, FeXapan, and Xtendimax only! This certification will not authorize one to purchase and/or use other restricted use pesticides. Attendees must complete a private applicator application and show a government issued I.D. to receive a private applicator license card. Please allow up to 45 days after the training date for the card to be issued. Documentation of attendance for this training will be the same as noted above for the UPW training.
The government shutdown has prevented access to FSA programs, however, offices are now open and deadlines for several programs have changed accordingly. Many of the deadline extensions have been changed to Monday, February 14 or Monday, February 28.
Our Forestry Update that was previously scheduled for this Wednesday, October 10 has been canceled. Once we have set a new date for this meeting we will distribute that information. The new date will likely be this December.
Below are Dr. Kemerait’s comments on the weather conditions concerning row crops:
“There is the obvious damage that wind and rain will bring, especially to the cotton crop- lodging cotton and putting lint on the ground. For cotton not yet ready to pick, the weather could increase boll rot, though there is really nothing we can do about that.
For peanuts, the question is timing of digging. It is my opinion that if the vines and pegs are healthy and not too much defoliation from leaf spot or damage from white mold is present, then it is better to leave the peanuts in the ground and to dig them after the storm passes.
If the peanuts are severely affected by leaf spot disease (significant defoliation) or disease (white mold) and the potential for yield loss is severe if they must stay in the ground into next week, then I would consider digging them.
If the crop is already behind in being dug (past harvest maturity) or the soil is “heavy” and digging may be delayed considerably, then I would also think about digging them.
Where peanuts are two or more weeks away from projected digging date, growers should consider whether a final fungicide application for management of leaf spot is needed.”
Pam Knox, UGA CAES Agricultural Climateologist suggests following updates from the National Hurricane Center at http://www.nhc.noaa.gov. Wind is of the main concern and will reach speeds high enough to cause a lot of damage to crops, trees, and power lines. Isolated tornadoes could also occur. She also suggests moving livestock and equipment from low lying areas. Conditions are expected to be worse than Hermine in 2016 so if generators are needed they should be prepared for use. Power outages could last for several days.
Here is an update from UGA Extension Pecan Specialist Dr. Lenny Wells:
Pollinated pecans begin to form
We have had a heavy bloom of female flowers and a good early nut set on ‘Desirable’ this year, but anyone that has been around pecans for long knows this cultivar has a nut drop in June each year. When this occurs the trees may drop as much as 30-60% of the nuts on the tree. The June drop continues to about 40-45 days after pollination, and is due to the lack of successful fertilization of the egg and sperm. This is an inherent characteristic of ‘Desirable’ in particular and this self-thinning is also the reason this cultivar can have consistent production from one year to the next
‘Stuart’ will also have a June drop but it is usually not as severe or as noticeable as the ‘Desirable’ drop. There is nothing you can do about this drop and there is nothing wrong with the trees when it occurs. If seeing this drop bothers you I recommend not going into the orchard to look until its over. Desirables always drop down from 4 and 5 nuts per cluster to 0, 1 and 2 nuts per cluster. The trees will still have good production. I began seeing this last week and it will likely continue for a week or so.
