Check your silo now for rotten staves. If you

ways for more water soluble

plant cuticle can be likened to a

properties of the wax appear to
be more important in restricting
penetration than thickness. Sur
face wax high in hydrocarbons,
aldehydes, and ketones is less
permeable to water and most
herbicide sprays than cuticle
membranes high in more polar
waxes such as esters and alco
hols. For example, the surface
wax of common lambsquarters
is known to be a strong barrier
to herbicide penetration.
Lambsquarters cuticle wax is
high in aldehydes which may
help prevent the passage of
