Which polyroid is useed to kill insects in store grain
Answers
Answer:
Equipment: Grain handling equipment should be kept clean. The effort involved in thorough preparation of storage bins is of little value if they are filled using contaminated equipment. Combines, trucks, augers and grain driers should be thoroughly cleaned of all old grain.
The Empty Bin: Never put newly harvested grain into bins containing old grain. Empty the bins of all residual grain, then use shovels, brooms and industrial vacuums to complete the job. Be especially careful to clear dust, webbing and fines from around any cracks and crevices, doors, seams, vents and especially under false floors. Even small amounts of old grain left in the bins may harbor enough insects to start a problem. Once the bins are clean, inspect them and repair any cracks or holes which would allow moisture or insects to enter. Then, spray the inside completely with an insecticide. (See Insecticides and Fumigants)
Near the Bin: The area immediately surrounding the bins should be kept clean. Be sure to remove and destroy all spilled grain. Control weeds and grasses, since they can harbor insect and rodent pests. Inspect outside walls and especially the base and roof for damage that could allow pests and moisture to enter. Do not use the area immediately surrounding the grain bins to store cattle feed; keep stock feeders as far away as possible.
The Grain: Store only clean, dry grain. A small percentage difference in moisture content can make a big difference in the probability of a damaging insect infestation. The optimum moisture content for stored grain is 12-13%. Most grain inhabiting insects require 13-15% moisture for maximum feeding and reproduction.
It is also advisable to clean grain before binning. Small pieces of dockage and cracked or split grain provide food for insects not normally found in whole grain. Even though most of these insects will not feed on whole grain, their biological processes produce heat and moisture which can greatly reduce the stored grain's quality.
Level the grain surface once the bin has been filled. This will allow for good air flow and thus improved moisture and temperature control. It also will allow improved access for inspection and treatment.
