be run very shallow around any crop
SO as to avoid breaking the roots of
the crop and if possible the crops
should be stimulated to faster growth |
by the application of additional fer
tilizer, particularly nitrate of soda. In
many light infestations of other in :
sects here we have frequently been
able to overcome the trouble by stim-
ulating the crop to greater power of
resistance with nitrate of soda.
busting with arsenical poisons. AS
general rule We have had much bet |
ter success here from applying pois-
ons in the form of dust than in the
form of spray, but 1t is frequently
difficult to get good results even with
dust on account of incessant winds
that blow the poison away from the
plant intended to reach. This dust
had best be applied in very early fore
noon or late afternoon when the air is
usually stillest and when the plants
are moist from dew of the night be-
fore Such work can be started now
as early as four in the morning and
continued as late as eight at night.
The cheapest poison Is Paris green
M; ,1l s,.e 81 xoI tn
portion of one part of the green to
twenty parts of the lime. Lime is the
best diluent because It is very cheap,
has some insecticidal properties, and
corrects the tendency of the Paris
green to burn the foliage of the plants.
In the absence of this lime flour, sifted
ashes and road dust may be used, but
/ II is best to use little lime always to
prevent the burning of the plants by
the green. Arsenate of lead In its
powdered form is even better than the
Paris green but should be mixed one
part to ten of the diluent and is there
fore more expensive poison. 1t does
not, however, have the tendency tc
burn the plants. Only the powdered
form can be used as dust.
This dust Is applied by means O
muslin bags or old -four sacks from
which 1t is sifted onto the plants
either by hand or from the back of
horse where the rider carries TIVE
bags, tied to the end of stick of prop
err length and shakes the bags as tn
animal walks along the rows, thus cal
rying two rows at time. From on
to two pounds Of the Paris gree
should be applied per acre and twic
as much arsenate of lead. A dustin
machine is made for the purpose bu
is expensive and possibly no more e.
fective than the sacks.
Spraying with liquid poisons.-l
the people generally had facilities fo
spraying plants rapidly, we would re-
ommend liquid poison made by mi
ing one pound of Paris green and tw
pounds of lime with about fifty ga
: Ions of water, but TO mix and put tn
out with small hand pumps is a slo
operation On very tender plants tt
l quantity of water per pound of Par
green should be increased up to or
+ hundred and fifty gallons, dependir
: on the crop. Always use the lime
: the green without it is liable to bun
u the foliage. Arsenate of lead in /
Il paste form is even better poison ths
y the Paris green as it is much less lik
e ly to burn the plants, but to have Il
u same effect in killing the worms
e must be used in twice the quantit
e Our opinion is that from one to tN
. pounds of Paris green per acre shou
e be used. In the absence of any XII
e of spray pump watering pots may
u used while yisps of straws or co
= shucks tied to end of stick may
u used very effectively. OF course Il
u is slow work for large areas, but
III practicable for small patches.
