SHORT SEMINAR ON BEANS
sch.
WESTEEL—ROSCO
GRAIN _ BINS
Usually July and August are decision months for white bean growers. To
spray or not to spray --- that is the question.
To help bean growers make this decision, Dupont Canada put on short
seminars at Exeter and Mitchell to discuss insects, molds, types of spray and
equipment. Speakers were John Heard, OMAF Farm Management
Specialist, Jeff Morton, a graduate student in environmental biology at
University of Guelph, Charles O'Shea who is growing 350 acres of beans at
Whelan's Corners and Lloyd Foster, Technical Sales Representative with
Dupont.
With this year's drought, few white bean fields have needed spraying.
However, the dry weather increased the damage from leafhoppers, Heard
told the group. Leafhoppers not only suck the juices out of the bean plant,
but a toxin in their saliva plugs the veins in the leaves so that moisture can-
not get through to the end of the leaves, thus causing browning of the
leaves.
Leafhoppers do not winter over. They fly up each year from the Gulf of
Mexico, multiplying as they move, and they thrive on hot, dry weather.
When you scuffled your beans, if you noticed the bugs flying up then you
should have sprayed.
The relative merits of aerial and helicopter spraying were discussed but
most of the group felt that the skid root sprayer gave the best protection.
The skid slides over the ground allowing the nozzles to spray up into the
centres of the bean plants. The operator has to watch that leaves torn off
the plants do not clog the nozzles.
