RESULTS OF A PROGRAM TO CONTROL WEEVIL IN TWO FLAT STORAGE BUILDINGS OF CORN FOR
RUMBOLD AND KUHN AT WYOMING ILLINOIS.
THE OWNERS USE THESE BUILDINGS JUST AS MOST
COOPS USE UPRIGHT TANKS. CORN MOVES IN AND OUT SOMETIMES ALMOST DAILY. FUMIGATING THEM IS COSTLY BECAUSE YOU FIGURE YOUR DOSE IN SQUARE FEET RATHER THEN HOW MANY BUSHELS ARE IN THE FLAT OR BIN. WITH BENEFICIALS THE APPLICATION RATE IS FIGURED ON JUST THE BUSHELS IN THE BIN, AND ADJUSTMENTS CAN BE MADE FOR THE GRAIN THAT MOVES IN AND OUT. ALSO FUMIGATION STOPS THE USE OF THE BIN OR FLAT WHILE THE GAS IS IN THE BIN AND UNTIL THE GRAIN IS ARREATED.
THE FOLLOWING CHARTS SHOW THE CONTROL THAT WAS ACHIEVED AT ONE OF THESE TWO FACILITIES.
82-FOOT SHED: THIS BUILDING WILL HOLD 600,000 BUSHEL, BUT ONLY HAD ABOUT 450,000 BUSHELS OF CORN IN IT.
21200 Anisopteromalus (AC’s) were scattered on top of the corn in two-week intervals to control the weevils. Greg Rumbold was pleased that he
could resume shipping this corn without having loads rejected for weevil infestation, and he was able to achieve this without the use of hazardous chemicals.
This is one of the growing number of satisfied customer who control the insect pests in stored grain with beneficial insects from BIOFAC CROP CARE.
