Later today, I’m giving a brief presentation and report at one of our groves on Early Pride dieback. We’re using two documents: 1) a pamphlet going over our experience in managing the problem, and 2) a paper co-authored with USDA on Early Pride. Here’s the link to both documents.
Recently, we’ve been looking at different roostocks for our citrus plantings. As seen in this mind map, there are no less than 15 or 20 different information sources that need to be considered. Much of this information is gathered over time, but there comes a point where you to refresh your memory to see if anything has changed since the last time you looked. How do you access and manage all the information that goes into making this kind of decision? If you’re like most people, you talk to others, email back and forth, read and you probably check 20 or so websites for the most recent information. That’s a lot of work, and becomes even more so if you have to do it more than once. I can’t disclose all the details yet, but I’m working with the University of Florida on a solution that will help growers make better rootstock decisions. Stay tuned for more later!
Last week, we reached a milestone in our Tamarixia release program–200,000 wasps released! Tamarixia is a parasitic wasp species that attacks citrus psyllids, which transmit greening disease. We’re interested in establishing Tamarixia in our area to help cover the declining backyard citrus trees that are difficult to treat for psyllid control by other means. We keep track of our wasp releases using our own iPhone app we developed (Tamarixia Tracker) to GPS and photograph each release.
Today, Drew Dyes from PFS and I are surveying citrus groves in Southwest Florida. This past week, I covered about 500 miles looking at groves around the state. I’ll update this post later with more photos and details, but generally, trees are looking better than they did the last two years on a similar drive.
Recently, I released a new version of Tamarixia Tracker that works in the Cloud. Here’s a quick little FileMaker script I added to make the app “iOS aware”. What this means is the app will detect your device (desktop, iPad or iPhone) and adjust it’s screen size and resolution for your device. The code from the Filemaker site is in the image.
We participate with the State of Florida in a program to release wasps that attack citrus psyllids, which transmit greening disease. Several months ago, I wrote an app to help us collect and organize the data. Well, this week, I’m happy to announce our wasp app, Tamarixia Tracker, is now in the Cloud! This cuts down on our administration time, and now we can report our wasp data back to the Dundee lab in real-time. Check out the video after the jump to see how it works!
We started collecting tissue sample this week. This will help us work out the optimum nutrition program for the trees. Depending on these results, we might also start soil tests, too. These are the hands of Drew Dyess from Plant Food Systems, who is helping out.

No one likes a good mobile app more than I. I think I have about 200 apps on my iPhone and iPad. Somehow, I seem to use most of them often. This includes apps like SoilWeb, Planimeter and four or five weather apps. However, there are times when I just need to write something down quickly, such as when a call comes in from the grove on something that needs to be acted upon right away. In these cases, I might not have time to whip out the PDA, turn it on, enter the passcode, start an app, get the type screen called up, and start typing away.
In these instances in the past, I’d jot something on a piece of paper lying around, or in an increasingly disorganized notepad. But I eventually worked out a better way. I call this, the GroveDex™ system. GroveDex™ is a PIM (personal information management) system that uses 3×5 index cards specially designed to handle the kind of grove information I have to use every day. In this post, I’ll show you what GroveDex™ is, and how you can even adapt it for your own use. In a second post to follow, I’ll show you a companion system that I call, “GroveMod™ PIM, which is based on the popular PocketMod technique for carrying ready-to-access information in your pocket.

WORKING DRAFT VERSION
In the first post in this series last week, I reported on some of our management success in controlling dieback in Early Pride citrus. I took a look at the symptoms of the problem and examined the progress of the disease over the course of a year in a new block we planted. Although I didn’t go into detail last week, I made the point that most of the dieback we saw was due to some sort of physical trauma. This week, I’ll take a detailed close-up look at those symptoms, and illustrate how I came to the trauma conclusion. In my next report due later this week, I’ll go over the findings of the USDA regarding secondary pathogens, and the treatment programs we used to help contain the problem in our grove.
