VIIVER. NEW YORK Watch Stored Grain TlIE 1955 crop year is our second largest, and storage facilities across the country are riear the bursting point. Much grain is stored in temporary units that have the welcome mat out for insects, rats, and birds. Rats and rodents destroy an estimated 382 million dollars worth of stored crops a year, and insects destroy another 217 million dollars worth of grain every year. With an eve on the grain storage situation, the Food and Drug Administration is beginning to crack down on wheat used for food. Two rodent pellets per pint or two per cent by weight o£ weevil damaged kernels will cause wheat to be declared "unfit for human consumption." If this happens to your crop, it will be channeled into livestock feed. Price difference is from 50c to $1 less per bushel. Stored grain should be checked once a month. If you notice crusting or dampness on top, it probably means one of three things: moisture is getting into your bin; the grain was stored with a high moisture content; or, insects are beginning to work. Shove your arm down into the grain and see if you can detect heat with vour fingers. If you feel heat, take a sample of the grain and sift one quart through a window screen. One adult weevil or grain .borer, or five or more of some other type of insect, means your grain needs fumigating. In the northern half of our country, rats and mice generally cause more damage than insects. Rat and mice control is a continuous job. The most important thins is to ratproof buildings. Eliminating trash, old lumber, and weeds will also help to control rats and mice. To prevent contamination by birds and poultry, screening is usually necessary. This includes all doors, ventilators, and other openings. Clean up spilled grain around bins. If contamination occurs in a bin, use the top five or six inches for feed. Let your stored prain watch word be "keep out" to moisture, insects, rodents, and birds, and you should have high-grade grain. These pictures show how weeds and grass can harbor rats and other^ rodents. Undisturbed growth on the left shows no signs of the rat burrow which is plainly visible when the grass is held away (right). Killing ihis kind of growth with chemical sprays exposes the burrow and discourages rats.
