Insecticide spray against Pine beauty
Photograph courtesy of David Foot, Surrey.
No information on location and year. Swiss based aircraft mounted with multi disc ULV sprayers carrying out a run over small pine trees. Trees are too small to be susceptible to Pine Beauty caterpillar attack and photographer is quite close to spray area unless wind is from them towards aircraft.
It is possible that this is a trial run without insecticide.
Any thoughts on location which is next to the coast would be very welcome.
