OPINION: By extension

The Harvey County Experiment Field will host is annual spring field

day on June 1 beginning at 6 p.m. at the Experiment Field headquarters

1/4 mile West of Hesston on Hickory Street. The field day will

feature tour stops on wheat varieties, Adage and Gaucho seed

treatments for corn and grain sorghum, cheat control in wheat using

Maverick and Olympus and spray nozzle technology. K-State specialists

will also discuss currents topics and answer questions. The public is

invited to attend.

Time for Spring Cleaning

of Wheat Bins

As the wheat crop matures in the field, farmers and others start

thinking about harvest and all the things they must do to be ready.

One important pre-harvest job is preparing storage bins for the 2000

harvested wheat.

Cleaning storage facilities and making them less susceptible to pest

infestation is the first step. Since newly harvested wheat should

never be stored on top of old grain, remove any old grain or trash

from the bin. Remove all empty feed sacks, seed litter, dust and

grain-baited rodenticides from the bin. A vacuum cleaner is a big

help in removing grain residue out of cracks and crevices.

Grain handling equipment can also harbor pests so don?t forget to

clean aeration ducts, sub flooring, augers, and the dump site? and

don?t forget the combine and truck. Spilled grain, weeds and debris

close to the bins also promote pest infestations. Mowing and/or

applying a herbicide to weeds outside the storage bin reduces the

area?s insect population.

Carefully inspect the facility and fill any holes, cracks or crevices

where insects and rodents can enter the bin. The best solution is to

fill them with permanent caulking materials. Check the roof for leaks

and holes to further reduce moisture and insect infiltration.

After cleaning and repairing, sanitize the bin. Apply Malathion,

methoxychlor, pyrethrins plus piperonyl butoxide, Reldan or Tempo to

bins and grain handling equipment prior to grain being stored. Follow

recommended label rates for application and allow for ample time to

accommodate proper waiting periods between application and filling the

bin. Spray walls, floors, ceilings, behind and beneath equipment and

on support beams. Pay extra attention to joints, seams, cracks,

ledges, and corners. Apply to the point of run-off.

For more information, ask the Extension Office for a copy of

?Management of Stored Grain Insect, Part III?, a fact sheet about

grain storage on the farm.

Harvesting High Quality Brome Hay

Smooth brome hay can be an extremely high quality forage if harvested

at the bloom stage. As a grass plant matures, forage quality drops

rapidly. Research has shown that crude protein will drop rapidly

between boot and mature seed stages. Brome hay should be cut between

early heading and full bloom to maximize quantity and quality. Crude

protein levels in well fertilized hay harvested at early heading range

from 10-18 percent , but protein levels drop rapidly after heading.

If seed production is the goal rather than forage production, seed

should be harvested when the stem just below the head has matured.

Freshly harvested seed has a small amount of moisture that can cause

the seed to heat when piled and reduce seed germination. It is

advisable to harvest brome seed in days when the relative humidity is

below 50 percent and harvested seed should be turned or stirred daily

to ensure heating does not occur. After the seed is harvested, the

stubble an
