PEST MANAGEMENT REPORT

NEWS ABOUT INTEGRATED PEST MANAGEMENT IN GLASSCOCK, REAGAN AND UPTON COUNTIES

  

GENERAL SITUATION

Hotter and Drier! Fleahoppers are still causing problems in some fields but in general they seem to be slacking up and more cotton is getting past the susceptible stage. Bollworm egg-lay has picked up some but remains light in general.

SCOUT SAFETY

If you treat the field the scouts are checking and the re-entry interval has not expired, please let them know so they will not unnecessarily be exposed to the insecticides.

FLEAHOPPERS

Fleahoppers ranged from 0-50 per 100 terminals and square sets ranged from 76%-95%. The higher fleahopper numbers and lower square sets are in cotton that is near bloom. Most of these fields will probably set enough fruit to make a good crop. The fields I am concerned with are the later planted fields that are in the first week or two of squaring. It is getting late to be treating for fleahoppers but if a field is not fruiting well it may necessary.

BOLLWORMS

Bollworm egg-lay is still low in most fields but one field northwest of Garden City had egg-lay Monday of 100% or 36,000 per acre.

Worm numbers ranged from 0-1500 per acre or 0-3 per 100 plants.

STINK BUGS

The high stink bug numbers found this week was 2 per 10 row ft. The threshold in our guide is 5 per 10 row ft. but many people treat at lower numbers. The scouts will begin to make four 10 row f t. samples in each blooming field from now on.

BOLL WEEVILS

No activity was found in traps on fields this week.

Reports from the Boll Weevil Eradication Foundation show only 3 weevils captured this spring in the trap line that runs from Sterling City to Garden City to Big Lake and back to San Angelo. Two were found just south of Garden City in early June.

FERTILIZER

If you are considering applying more nitrogen to your drip irrigated cotton you need to get it applied within the next 2 weeks so that it does not cause excessive late season growth.

ONCE IN A MILLION

By Frank J. Dainello
Editor

With the increasing level of sophistication of detection devices available today, substances can now be found that were not detectable just a few years ago. Consequently, undue alarm is often generated by reports that a 5 to 10 ppm (parts per million) of some pesticide residue was found in a given produce item. In most cases, these levels are so small that they cannot constitute a health risk. The following, taken from a newsletter of the Associated New York Food Processors, may help to visualize just what is meant by these values.

Think of one part per million as 1 inch in 16 miles; 1 minute in 2 years; 1 cent in $10,000.00; 1 ounce of salt in 31 tons of potato chips; 1 bad apple in 2,000 barrels.

One part per billion compares with 1 inch in 16,000 miles; 1 second in 32 years; 1 cent in $10 million; 1 pinch of salt in 10 tons of potato chips; 1 lob in 1,200,000 tennis matches; 1 bad apple in 1 million barrels.

It is not uncommon today to find a report detecting ppb (parts per billion) of something in a produce item. Considering that there are 1,000 million in a billion, I personally find it hard to show much concern over foreign residues of the magnitude of 5 to 10 ppb!
