NATION, Page 21American NotesMINNESOTADay of the Locusts
The rich farming areas of western Minnesota, still suffering
the effects of last year's drought, now have a plague to contend
with: millions of crop-destroying grasshoppers are creating
conditions reminiscent of the Dust Bowl 1930s.
Dry weather has prevented the germination of a fungus that
kills the locusts' eggs, enabling two particularly harmful species
to hatch in overwhelming numbers. Since spring the hungry hordes
have infested thousands of acres in 36 counties, chewing up wheat,
corn, sugar beets and soybeans. Normally, fewer than ten locusts
occupy the average square yard of land; crop damage begins when the
number rises to about 30. This summer some Minnesota fields are
aswarm with as many as 1,200 hoppers per sq. yd. Fields in the
worst areas look as if they had been struck by hailstones.
State law requires control measures on infested property. But
chemical spraying, the only real choice in some areas, disturbs
environmentalists. They say the more effective pesticides can wipe
out virtually all insects in an area and may also threaten
drought-weakened wildlife. Organic farmers fear that the chemicals
will taint their crops, shutting them out of a lucrative market.
Yet if nothing is done soon, the problems could multiply: the
maturing locusts are expected to lay more eggs in August.
