McAvoy said the tests show differences in varieties for
anthracnose occurrence and severity.
That study is also examining irrigation and fungicides
for cucumber varieties. Anthracnose on cucumbers
is a separate pathogen species than anthracnose on
watermelon. McAvoy said he hopes the research will
produce recommendations on varieties and irrigation
scheduling growers can utilize.

pathology professor and Extension vegetable disease
specialist, are looking at fungicide screenings and
collecting isolates to determine if the disease populations
are fungicide resistant populations.
Last year was the first year of trials, which include
known susceptible and resistant seeded and seedless
varieties to determine which varieties perform best.
Extension personnel are screening varieties and
evaluating irrigation management practices for
anthracnose control. While analysis isn't complete,
narrow plastic beds during warm spring temperatures
for earlier production on agronomic fields, large scale
production of cotton and peanuts, and are irrigated via
the same overhead systems. Researchers are examining
irrigating in the morning, midday or at the end of the day.
A hypothesis holds if water is applied at the end of the
day, disease could increase through moisture remaining
on the leaves through the night.
Spacing factors
Because grafted watermelons are four to five times
more expensive per plant than non-grafted plants,
McAvoy is studying how more expensive grafted plants
can be planted further apart without reducing yields.
Many growers will grow on a configuration of 8 feet
between rows and 3-4 feet between plants, but at
McAvoy's farm, he grows on 6 feet between rows. On
