Cleaning, flushing, triple-rinsing… whatever you call it, sprayer sanitation is a time-consuming and distasteful task. Methods vary, but they generally span from the classic triple rinse (30-45 minutes) to a full tear-down and decontamination (many hours and likely an overnight soak). The operator decides how much time and effort to invest depending on the chemistry they’ve […]
Next to sprayer math, cleaning the sprayer is one of the more distasteful aspects of airblast spraying. It’s time-consuming, you never really know when you’re finished, and sprayer manufacturers and pesticide labels offer only limited guidance. Clean sprayer rinsate often looks and smells exactly like contaminated sprayer rinsate. When airblast sprayers are not cleaned as […]
One of the most challenging aspects of a spray operation is the disposal of leftovers or rinsate containing pesticides. Let’s be honest, too much of it is drained onto the ground in a corner of the yard or the field. Nobody’s happy about that, nobody’s proud of it, but what are the alternatives? Waste disposal […]
(This short article is an addendum to this article) Our goal in this example is to dilute by a factor of 20,000. The maximum amount of dilution possible with a 1,200 gallon tank and a 30 gallon remainder is 1200/30=40. The formulae: Dilution per Rinse = final dilution ^(1/# of rinses) Rinse Volume = (dilution […]

One of the more perplexing questions in tank cleanout is knowing when the cleaning process is good enough to prevent harm. This question is especially relevant to producers that grow canola and use Group 2 herbicide products, or grow soybeans and use dicamba on some of their area. In both of these examples, crops can […]
