per capita compared with 16 PBJ and 12.9 hamburgers.

 

ENTOMOLOGY

 

Time for multicolored Asian ladybeetle overwintering: It is nearing the period of the year (usually late November and December in North Florida, but earlier if the weather gets cold) when Harmonia axyridis begins to seek overwintering quarters and enters dwellings and other buildings. The ladybeetle appears to be very abundant this year and is currently found in high numbers on pecan and crape myrtle where aphids are present.  Once they are inside a building, a blacklight trap will capture and remove them at night. The only thing a homeowner can do is to seal up cracks and crevasses as much as possible to decrease the probability of entry. The ladybeetles are very important predators of many insect pests which reduces the need for pesticide use. County faculty should convey this positive benefit to clientele when queried for help. I am continuing efforts to prefect a trap to help capture the ladybeetles before they enter buildings and hope to have a patentable product at year's end.

 

Nursery pest management: I have noticed what appears to me as an increase in the abundance of Florida wax scale populations around the area this fall, particularly on hollies. Indian hawthorne is also a favorite host.  Florida wax scale is a soft scale and produces copius amounts of honeydew which serves as a substrate for sooty mold. Most observers will see the black sooty mold on the plant before they see the scales. The scales are white star-shaped masses that resemble a small wad of chewing gum with similar consistency. As with all scales, Florida wax scale is best controlled by targeting the egg and crawler stages. However, a dormant oil will also suppress their populations. Remember that the adult females (there are no males of this species) only reproduce one time and then die. However, they may adhere to the plant long after they are dead from natural causes or from chemicals. They can be removed by hand from saleable plants, but it is best to prevent infestations.  Both nursery and landscape plants are susceptible. 

 

Homeowners and fruit growers should also be aware of scale damage. White peach scale and San Jose scale can be very damaging to fruit trees, especially peaches and nectarines. White peach scale males are easily seen due to their fuzzy white appearance. San Jose scale often goes undetected until the damage is extensive. San Jose scale are quite small and silvery in color. Again, target the egg and crawlers stages or use a dormant oil.   

 

Pecan harvest:  Pecans are beginning shuck split and harvest time is here. Now is the time to determine the extent of damage by the direct nut pests stink bugs, pecan weevil and hickory shuckworm. Shuckworm larvae mine the shucks and interfere with the dehiscing of the shuck from the nut.  Pecan weevil larvae are inside the nut and evidence of weevil presence will be the small hole in the nut and destruction of the nut kernel.  Remember that pecan weevil has a two and partial three year life cycle so the populations you see this year will return as adults in 2003 or 2004.  Growers should map there orchards as to what trees have weevils and use the Tedders or Circle traps to monitor for adult emergence.  Be on the lookout for stink bugs. Their damage will be black spots on the kernel that impart a bitter taste. Stink bugs may damage the nuts even in the wagon as they go to the barn.  (Mizell, NFREC News, 3-22)

 

LIVESTOCK

 

Wild Pigs – Hidden Danger for Farmers and Hunters

 

In Florida, it has been estimated that there are 500,000 free-ranging wild pigs (also called feral pigs or feral swine).  This wild pig population is about ten times that of domestic swine in Florida.  Nationwide, wild or feral swine are present in at least 18 states, primarily southeast and south central states, and coastal California, with a total population estimated at two million.  Texas has the largest population, estimated at one million. 

Pigs are not native to North America.  Domestic pigs were introduced in 1539 when Hernando de Sota brought them to Florida.  Early on it was common practice for settlers to allow domestic swine to roam freely.  Years later, sport hunters introduced the true European wild boar into parts of the USA, and their bloodlines have become mixed with those of feral swine.  Today, some of the feral or wild pigs have the classic “wild boar” appearance while others resemble domestic swine in color and body shape.

Wild or feral pigs are popular for sport hunting, but unfortunately wild pigs can cause a great deal of damage.  Hunters, farmers, and landowners should be aware that wild pigs can harbor infectious diseases and can damage crops, pastures, native plants, and wildlife habitat.  Allowing wild pigs onto farms that have domestic pigs can have disastrous consequences.  Many wild pigs in Florida are known to be carriers of two serious swine diseases:  swine brucellosis and pseudorabies.  Thus, care must be taken in not allowing wild pigs to come in contact with domestic swine.  In addition, hunters can contract brucellosis if they are not careful when they dress wild pigs.  Further information is available in USDA’s Agriculture Information Bulletin No. 620, available from:  Publications Distribution, USDA APHIS, MSD, PDMB, Room 6-110, Federal Building, 6505 Belcrest Rd. Hyattsviille, MD 20782 (www.aphis.usda.gov).  (Myer, NFREC News, 3-22)

 

 

Security Considerations Relating to Pesticides

 

            Considering the September 11th, 2001 terrorist attacks on the United States, and the subsequent focus by the federal government and national news media on aerial pesticide applicators, the National Agricultural Aviation Association has initiated a campaign to improve aircraft and operations security.  The NAAA recommends that, where possible, aircraft and crop protection products are stored in locked hangars with electronic security systems when not in use.  Loader trucks, forklifts, or other equipment may also be parked and temporarily disabled in such a manner as to block movement of the aircraft.  In cases where hangar space in not available and aircraft must be left outdoors, propeller chains, locking high strength tie down chains, or blocking equipment are practical alternatives.  Outdoor security lighting is also recommended.

 

            NAAA also encourages operators to explore the possibility of installing hidden security switches in compliance with FAA regulations to ensure unauthorized aircraft starting.  In the case of operators who live on the premises, or have employees living on airport grounds, enhanced security lighting, alarms, and dogs are effective deterrents against criminal activity.

 

            NAAA recommends that operators establish contact with federal and local law enforcement agencies to coordinate responses to security breaches at agricultural aviation facilities.  Appropriate law enforcement agency telephone numbers should be posted in a prominent place and employees should be instructed to maintain enhanced security awareness.  These telephone numbers should be registered with any private security company that monitors the electronic security system of an agricultural aviation operation.

 

            On a broader scale, the Environmental Protection Agency has issued an alert to all pesticide industry organizations, facilities, and handlers as a precaution during this heightened state of security awareness. Guidelines include the following

 

1. Securing Buildings, Manufacturing Facilities, Storage Areas, and Surrounding Property: One of the most fundamental security needs is the prevention of intrusion to areas used to manufacture or store pesticides and other toxic chemicals. Elements of an effective security plan can range from basic fencing, lighting, and locks, to intrusion detection systems, cameras, and trained guards.

 

2. Securing Pesticide Application Equipment and Vehicles: Facilities and pesticide businesses should ensure that they have appropriate security protections to prevent intruder access to equipment used in mixing, loading, and applying pesticides. Before operating pesticide application tools and vehicles, handlers must have proper authorization and identification.

 

3. Aerial Application Equipment: Security awareness is particularly important for large-scale pesticide application equipment like aircraft and large trucks. The FBI has requested that aerial applicators be vigilant to any suspicious activity relative to the use, training in, or acquisition of dangerous chemicals or airborne application of same, including threats, unusual purchases, suspicious behavior by employees or customers, and unusual contacts with the public. Any suspicious circumstances or information should be reported to the FBI.

 

4. Protecting Confidential Information: As business, safety, and security systems become more reliant on computer and communications technology, the need to secure these systems has grown. Such efforts include contingency planning for power losses, effective monitoring of access ports, adherence to password and backup procedures, and other mechanisms to maintain access for authorized personnel only.

 

5. Designing Facilities and Equipment to Minimize Risk of Damage: Whether an intrusion to a computer by a hacker or a physical intrusion of your facility by a vandal or saboteur, it is important to take steps to minimize the extent of damage. For example, in order to prevent damage, the use of sturdy, reliable, and potentially blast-proof materials is essential in the construction of equipment used to transport and apply pesticides.

 

6. Developing Procedures and Policies that Support Security Needs: Even the best hardware and staffing budgets are only as effective as the procedures and policies that control their use. Effective hiring and labor relations policies are important to obtain and retain good employees who will support and follow safety precautions. For example, the hiring process should ensure that pesticide handlers have all requisite training necessary to handle pesticides safely. Background checks of staff who have access to secure areas, particularly those areas where pesticides may be stored, are also necessary.

Inventory management policies can help limit the amount of potentially hazardous pesticides stored on site, reducing the risks of accidental or intentional release or theft. Effective advance emergency response procedures can be critical, helping ensure that business officials and employees understand how to respond and whom to contact in the case of an emergency. Aside from accidents, such plans must also consider vandalism, bomb threats, and potential terrorist activity.

 

7. Timely Coordination With Authorities: If a breach of security or suspicious activity does occur, timely cooperation with authorities is crucial. In addition to cooperation with your local police department, the FBI requests that you expeditiously report any threats or suspicious behavior to your local FBI field office. Information on the location of the appropriate FBI office is available at www.fbi.gov.

North Florida Oat Grain Variety Trial Results For 2001 And Four

Year Averages With Recommendations For The 2002 Season

                                 (NFREC-QUINCY RESEARCH REPORT 2001-8)

 

R. D. Barnett, P. L Pfahler, A. R. Blount, D. L. Wright and L. G. Schell

 

Oats are the most versatile of the small grains.  Oats are an excellent winter grazing crop and livestock grazing oats perform very well because of the high quality and palatability of the forage.  Oats can also be used to produce excellent quality stored forage - hay, haylage, or silage.  The grain can be used by a broad range of livestock and is a very good feed grain, on which animals perform well.  Oats are the best suited small grain for dual purpose (grazing then grain) use.  Oats also are very popular and work well in wildlife food plots.

Oats are an excellent crop to grow in rotation with wheat because they do not harbor diseases that attack wheat, rye, and triticale.  Oats are also resistant to the Hessian Fly which poses a serious problem on early planted susceptible wheat varieties.  Oats can be planted one month (Sept. 15) earlier than rye or wheat (Oct. 15) when used for grazing.  The fact that oats are more tolerant to high temperatures and more resistant to seedling diseases allows for the earlier planting date.  However, oats are not as cold tolerant as wheat or rye and will suffer some cold damage during cold spells (below 20oF).  Oats should not be grown for grain on land planned for certified seed of wheat or rye the following year because of a tendency to produce volunteer plants.

Horse feeding trials with Florida grown oats have shown them to be very acceptable and performance data indicate that the feeding value was comparable to northern grown oats.  Most horse owners want bright, heavy oats to utilize in horse rations, which are difficult to produce in Florida.  If you want to try to produce “race horse” oats we would recommend the following:

1.  Select fertile, well drained soils and use a generous fertility program.

2.  Plant during the second half of November and utilize a relatively low seeding            rate (75 lbs/A).

3.  Choose a variety that produces grain with a heavy test weight.

4.  Topdress with 50-60 lbs N/acre the last week in January or the first week in               February.  You might want to consider split nitrogen applications (35 lbs the             last week of January followed by 25 lbs 3-4 weeks later).

5.  Harvest promptly before rain or dew has an opportunity to discolor the grain.             It may be necessary to combine at high moisture and artificially dry the grain.

6.  It may take some cleaning or processing to get the test weight up to the 38-40            lbs/bu required for high quality horse oats.

 

Data collected from recent grain performance trials in Florida is presented in Tables 1-8.

Recommended oat varieties and their characteristics are provided in Table 9.

Extension Design Team Affiliation: SMP131 – Quality and Management of Florida State Diagnostic Services. This is a new POW team that has been appointed to provide direction and insure quality of services provided by UF/IFAS.  DDIS is a major component falling directly under this SMP.

 

Introduction

Digital identification and diagnosis of plant diseases and insects have received considerable attention and funding by UF/IFAS recently.  A system that allows effective communications and archiving of images and data, has been developed in collaboration of county faculty, specialists and faculty in IT.  The viability of the system has been demonstrated by the initiation of a pilot project involving ten county extension offices and nine extension faculties and specialists. 

 

There was a need to validate the methodology, obtain benchmarks of accuracy and identify points in the process at which errors might be introduced. This is needed to streamline the operation as well as to insure the correctness of the identification and diagnostics.

 

This study proposed a comparison of diagnostics and identifications (D&I) made by conventional means and using DDIS. The objectives were: Measure the frequency of success, identify reasons for failed D&I, make specific recommendations to improve DDIS, and evaluate the use of DDIS as a resource for education programs for IST of county faculty.

 

Materials and Methods:

Cooperators sent both live samples (as done conventionally) and digital samples.  Specialists conducted 

diagnosis using DDIS and used live samples to validate the diagnosis. Several educational meetings, including in-service trainings were conducted in 2000. Educational materials including 3 APS Disease Compendia per cooperators were purchased and distributed to 22 counties.  Tools were purchased for counties to use for the preparation of microscopic slides under compound microscopes.  One set of DDIS microscopes were purchased for road show and trainings.     

 

Results and Discussion

This project created several educational opportunities for participating extension faculty to gain more knowledge on plant pathology, entomology, plant disease and insect diagnosis, digital imaging of biological materials and web-based technologies. DDIS provided a tool and resource for educational instruction and practical exercises in IST of county faculty. The validity of DDIS for some groups of diseases and insects was evaluated (Tables 1 and 2).  This type of data is not present in the literature.  A refereed journal article and four EDIS publications were developed concerning the diagnosis of plant disease and insects through DDIS in Florida.

 

Table 1. Summary of DDIS validation data and correct diagnosis (ID) rate for plant diseases

using DDIS in 2000 in Florida (validated by live samples).  Out of 140 digital DDIS samples

received,  98 of them had  only both digital and live samples.

Total of 98 DDIS disease samples (98 digital, 98 live) were evaluated    (100 %)

Overall correct ID using DDIS (24%)

To enhance and strengthen the accuracy and validity of DDIS, specific recommendations will be made based on the results of this project. DDIS will be modified in accordance with the feedback received from end users.  Digital capabilities and the World Wide Web minimized physical transport and changed the way we communicate for diagnosing and preventing plant diseases and pests.  This is a first-year progress report of the project.  A refereed journal article will be prepared at the end of the second

year.  (Momol, NFREC News 3-22)
