Spot spraying restock

[N1ck]

Any idea how many trees you can spot spray in a day with a knapsack. Reasonably flat site, clearfell restock, allowing for tank refills, breaks etc.

Depending on surface area and the size Tank I suppose you could spray thousands.

The only problem is after the first hundred or so with no previous experience you will start to peter out pretty quick. If this is a one off situation I say try the manual pump method.

Otherwise buy a motor operated model and work smarter not harder.

If trees are in rows you will do more, I did it a long time ago when I worked for someone must of do 4000-5000 aday in the middle of summer. I only used to half fill knapsack which ment you could stick it all day.

It'll depend hugely on ground conditions, whether or not the second plantings have been mounded and the volume of the dose.

 

A (very) long time ago I used to do this at weekends with three pals on second plantings here in Argyll (I think against pine weevils). We'd carry 50l tanks on our backs and had to wear taped up pvc suits, wellies and full head protection etc. The 'spray' was actually a sheep dosing gun which was bl**dy hard work on the forearm and hand after a few hours. Typically we would do 10-12 tanks a day (each) when the plantings were buried in the brash, but could manage more than 15 tanks a day if they were mounded.

 

Very hard work, but good money and I've never been as fit!

Last time I measured it ,my mate and I walked 11 miles in a day each and about 300 litres each.

I used to do 20 knapsacks when I was sprightly.

Any idea what that equates to in terms of individual trees per 15 or 20 litre tank? I know it depends on nozzle / spray density etc. but ball-park?

I do this every summer, Depends how easy the trees are to see for numbers wise but if its good 4000-5000 trees a day is what I would aim for. like said only put 10 litres in your tank.

 

 

Just checked my spray records, to cover a hectare of trees 2800, we were spraying 60 litres of mixed roundup at 200ml to 10 litres.
