Maintaining a healthy, vigorously
growing lawn is the best way to prevent
a severe disease outbreak in turfgrass.
Each square foot of turf contains about
500 to 1,000 individual plants, each
requiring optimum amounts of water
and fertilizer, the right mowing regime,
and an aerated, well-drained soil. If any
of these factors are missing or in excess,
the grass may become stressed and
more susceptible to disease.
For a disease to occur, all three...

INTRODUCTION
Corn (Zea mays) is the most widely produced
grain in the United States. Approximately 80
million acres of land are planted to corn. In India,
where the Brown Stripe Downy Mildew (BSDM)
pathogen was first discovered, yield losses from
BSDM range from 20-70%. If BSDM were to cause
comparable damage in the U.S., it would translate
to a $4.6-16.1 billion financial loss
1.
Because of this potential impact, BSDM has been
designated a...
