“Buying that much herbicide is not cheap”
I’ve recently been applying herbicide to my 2,500 sq feet of lawn and you are right — it is expensive. That was the first thing that occurred to me, too. Enough herbicide in a tanker truck to do the job would be a lot of money.
If that much herbicide had been stolen, it would have garnered some notice.
There are so many weird things going on that are not understandable - 30% of the population wanting communism, BLM destroying race relations ostensibly to improve race relations, hatred of the inventors and producers because they are white, hatred of Christianity and churches.
This sounds more like a personal vendetta. Somebody did not like this farmer.
Buying this much herbicide could easily be traced to its retail or more likely wholesale source.
Buying just a gallon of concentrated Roundup is expensive. Buying 50+ gallons would be very expensive(thousands of dollars).
Also, there are not that many sources for a quantity of that amount.
