Who should apply pesticides?

Anil Mukhiya  Follow

The first rule on applying pesticides is to read the label and follow the directions. Next, is to apply an appropriate pesticide for the pest and apply it with following pesticide guidelines. Incorrect pesticide applications have often ended in the death of innocent people. Certain pesticides can only be applied by licensed applicators, who know and follow the directions.

No matter which pesticides you use, use appropriate personal protective equipment (PPE’s) and wash them thoroughly after use. Many require the applicator to bathe after use as they can continue to be exposed to the residue on the suit and on your body after application.

I also add, use pesticides only after other remedies have been tried first. (Pick the squash bugs off instead of poisoning them.) Some pesticides remain on the plant and on the ground for long times after use. This was one of the problems with DDT, not to mention that it harmed wildlife.

Use Integrated Pest Management:

Steps in Integrated Pest Management (IPM)

1. Identify species involved

2. Is it a pest/beneficial/neutral?

3. Establish priorities

4. Determine level of tolerance

5. Establish action thresholds

6. Monitor pests and environment

7. Implement non-chemical management

8. Use pesticides sparingly

9. Evaluate - continue monitoring

Many years ago I worked in a greenhouse and was poisoned by malathion that had been sprayed the previous year and had been adsorbed and later released by the plastic sheeting. It took months to diagnose the problem and years to cure it.

During those years I was hypersensitive to pesticides, becoming acutely ill on several occasions when I was inadvertently exposed. One of those exposures occurred when I took two bites of an apple, purchased from a local orchard, before feeling the effects of the spray. My wife contacted the grower who confirmed the apples had been sprayed with chlorpyriphos, a stronger form of malathion, about 4 months ago, the time period far exceeding the manufacturer's withholding period.

So yes, pesticides sprayed on any food can be harmful. That is the reason that I always eat and recommend organically grown, spray-free fruit and vegetables.
