Thats what I meant to say Len, The propellant is a gas, (butane I
believe) and that when its released acts as a refrigerant, It cools
things donw rapidly. Same as filling a gas bottle, you see frost form on
the surface. IE can cause cold burns on plants. The same as heat burns.
Whether there is a difference in early morning or late spraying, I dont
know...

anotehr to consider jonno,

when i used to spray i always did so after the heat of the sun, in the
afternoons or early evenings.

and aerosol cans carry the added down side that the propelants could
cause plant damage.
