3 Audience
• Who eats potatoes?
• Who has done projects with Oracle APEX? Who’s thinking about it?;
• Who used APEX in combination with webservices.
4 Agenda
• Why is there a need for 4D;
• What makes 4D;
• Showcase (screenprints);
• Questionaire
In dutch 4D stands for: Digitale Detectie en Diagnose Dienst

7 Why 4D
“To develop a system that can
electronically detect and diagnose crop
diseases, such that they can be treated
fast and accurate.”
8 Why 4D
focus on Alternaria solani
• Wide spectrum agents are no longer allowed and spraying to prevent is
not preferred due to european quota and ledgislation;
• Not treating Alternaria costs money;
• A non-specialist (farmer) in most cases has difficulties diagnosing
Alternaria solani.
• To be sure a non-specialist (farmer) has to ask a laboratory such as
HLB to diagnose;

most of the time
10 Why 4D
• Alternaria can spread fast.
• Not treating Alternaria S. can
mean losing 1/3 of yield.
• Alternaria makes a plant
susceptible to other pests like
Phytophthora infestans.
(20 tonnes on a production of
60-70 tonnes/ha,approx. €0,12
per kilo means €2400,- / ha;
avg. company sizes up to 60
ha so about. €144K/season );
11 4D
Phytophthora infestans (late blight)
•Spores develop on the
leaves; rain washes them
into the soil, infecting tubers.
•Infected tubers start to rot
even in storage.
•In The Netherlands 90
percent of potatoes is stored
to bridge the 8 month period
until the next harvest;

Future
`Functional’:
•More crops, now only potato;
•More diseases, now only alternaria;
•Improved image recognition;
•Improved expert system, based on Bayesian networks;
APEX:
•`Native’ webapp for iPhone / Android (jQuery mobile, Phonegap, iPhone photo picker)
•Port to APEX 4;
