  1. Scouting: How, When and What Jamie D. Yates University of Florida, IFAS, Citrus Research and Education Center Lake Alfred

  2. Scouting in 2008-2009 • Scouting is no longer an option, but essential to managing greening • How successful do you want to become? • Aim to stay viable and productive in the citrus industry

  3. Train Your Scouts • Become familiar with the symptoms • Trainings available from UF-IFAS upon request • Online interactive training • Visit another grower with greening infected trees • Follow an experienced scouting crew • Essential to communicate with scouts (both English and Spanish) • Everyone learns differently!

  4. Make a Plan-Choose your methods • Walking • Closer inspection of trees • Easy in young to mid-sized trees • ATVs • Faster than walking, but does not allow close inspection and difficult in tall trees • Elevated platforms • Best view of upper canopy • Must have scouts on both upper and lower platform • Reliable drivers are essential

  5. Make a Plan-Survey path Steve Futch. Ph.D.

  6. Make a Plan-Design a flagging system • Suggested Practices • Flag individual symptomatic branches • Write scout’s name and date on flagging tape • Flag each end of the row with number of flagged trees noted • Hedging can remove flagging material and create re-inspection/removal issues • GPS can also be used, but should be used in conjunction with flagging tape • Use a colored flagging tape specifically for greening

  7. Scout on Time • Minimum four times a year • Symptoms are most difficult to see during the spring and summer flush • Remember safety first!

  8. Scout on Time • Plan your scouting program around your regular grove care practices • Don’t mow, hedge or apply chemicals in the same block with scouts • Prepare grove to improve efficiency of scouting, i.e. remove excessive weeds • Maintain proper grove maintenance • Scouting after a chemical application may be more difficult, be aware of REI of recently applied pesticides • Be flexible in Florida weather conditions including lightning and windy weather

  9. Focus • Remember your focus! • Symptoms • Blotchy mottle • Yellow veins • Vein corking • Green islands • Off-season bloom • Lopsided fruit • Off-colored fruit

  10. Pen Test • Determine if symptoms are the same on both halves of the upper or lower leaf surface • Draw two circles on opposite halves of the leaf • Is the pattern the same in both circles?

  11. Scouting Resources • Revised laminated sheets • Training DVD • Revised Greening Field ID Pocket Guides • NEW! Online Interactive Training • NEW! Greening brochure • NEW! Scouting for Citrus Greening brochure • NEW! Scouting for Citrus Greening (EDIS)
