Forget the attack of the killer tomato, this is the attack of the
healthy tomato: A team of scientists has developed a tomato that contains
as much as 3.5 times more of the cancer-fighting antioxidant lycopene.
It turns out that the antioxidant-rich tomato was a happy accident.
Scientists at Purdue University and the U.S. Department of
Agriculture's Agricultural Research Service were working to develop
tomatoes for food
processing that were of higher quality and would ripen later.
They accomplished that, but in the process they discovered that
the new tomatoes also had significantly more of the antioxidant
than conventional tomatoes.
"We were quite pleasantly surprised to find the increase in
lycopene," says Avtar Handa (pronounced "Honda"),
professor of horticulture at Purdue.

Physiological Leaf
Spot of Tuliptree
Hot weather of summer brings with it yellowing and premature drop
of tuliptree leaves. This unexplained disorder, apparently caused
by environmental stress, commonly develops in tuliptrees during
hot, dry weather. An additional symptom that frequently accompanies
the leaf yellowing is the appearance of circular, black spots between
the veins of the yellowing leaves.

Give Asparagus and
Rhubarb a Break
Asparagus and rhubarb may be the earliest garden crops to be harvested,
but they may also be the first crops you stop harvesting as well.
Because of their perennial nature, asparagus and rhubarb must be
given a chance to rebuild food reserves so that a bumper crop can
be produced again next year.

Japanese Beetles Emerging
in the Rain!
How will the rain affect the white grub populations this year? Wet
weather this spring will have little effect on grub populations.
Japanese beetle adults are just starting to emerge in southern Indiana
and will emerge in full force throughout the state within the next
few weeks.

Southern Blight of
Hosta 
The destructive fungal disease known as Southern Blight is an aggressive
stem-rotter of a wide range of species, including not only flowers
and vegetables, but also some field crops and fruit trees. This
soil-borne fungal pathogen is favored by high temperatures and high
humidity. Controlling Southern Blight is difficult because the pathogen
has a wide host range, and because the sclerotia persist in the
soil.
