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.
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!
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.
Tamarixia Tracker, my free app for to citrus growers to help them track and report their wasp releases to the Dundee Biological Laboratory, was just updated to Version 5.1. This version adds language required by the state regarding non-endorsement. We’ve worked with the state to develop the app’s forms and interface, but they asked to make clear in the splash screen that it’s not officially funded by or associated with the Division of Plant Industry.
We completed our Tamarixia work this week and we’re now at 100,000 wasps released! This is a big milestone and we hope to find wasps in the wild soon. We release in unmanaged groves to give them the best chance to survive. My custom app, Tamarixia Tracker, helps us get the information back to the state quickly. In fact, we often have our report data tabulated and sent to the state within an hour or so of completing our release work.
As told in our full story and our article for the Indian River Citrus League, we talk about an exciting program we’re working on with the Division of Plant Industry for non-chemical ways of controlling Asian citrus psyllid. We’d also like to introduce a new “right here, right now” technology solution we developed to help with our role in the program. This is an iPhone app for tracking Tamarixia wasp releases.
In April, 2014, I met Drew Dyess and a friend for a photo shoot in a citrus grove. Drew, who works for Plant Food Systems, wanted some good photographs to use in his work. This would be one of those rare opportunities where you can get great images of citrus people working in the grove. I met Drew and his friend after work one afternoon. His friend helped us out by serving as our lighting director, and Drew carried on about his work while we shot away. The results turned out great–be sure to check out the gallery below!
