PPI Spring Meeting 2001 - Abstract
Disease Control Strategies in Pickle Production

There are approximately 11 important infectious diseases of cucumber
in North Carolina. Fungicides continue to be an important disease
management tool for at least five of these (anthracnose, belly
rot, damping-off, gummy stem blight, and target spot). In recent
years, three new fungicides have been registered for use on cucumber.
These include Quadris (azoxystrobin) and Flint (trifloxystrobin),
which belong to a new chemical group called the strobilurins.
The strobilurins are based on a natural compound produced by a
small mushroom (Strobillurus tenacellus). This compound has specific
activity against fungi and low toxicity toward non-target organisms
(e.g., plants, mammals, birds, insects, and earthworms). Other
variations of the strobilurin compound have been developed for
use on other crops, and more are currently in the development
process.
It is important to know how effective these products are against
important cucumber diseases (e.g., anthracnose, gummy stem blight,
belly rot) in relation to more traditional products (e.g., Bravo
and mancozeb). In this presentation I will discuss when and how
these products fit into an effective disease control strategy.
