16 FARMERS’ BULLETIN 141. 
SUMMER SPRAYING. 
Many farmers have sprayed the stubble after removing the first 
crop, with results about qual to those of the brush-drag treatment. 
The same apparatus cai be used as for the spring spraying, but the 
usual method has been to distribute the spray through two leads of 
hose and two Bordeaux nozzles, each handled by a man who walks be- 
hind the outfit or rides upon it and covers the ground as evenly as pos- 
sible and as far as he can reach with the spray rod. Both Paris green 
and arsenate of lead, in the usual orchard strengths of 1 pound and 
6 pounds, respectively, per 100 gallons of water, have been successful. 
This treatment is more rapid than the brush-drag method, but it 
requires special machin ry. For orchard districts it is very promising. 
PUDDLING. 
Several farmers have protected the second crop by dragging the 
stubble, while it is still wet from irrigation, with the land leveler or 
the clod breaker. This process embeds the insects in mud, in which 
they perish, and effectually prevents them from attacking the sprouts. 
It is easier than the dust-mulch method, but it is harmful to the soil 
and is not recommended. 
PREVENTION OF SPREAD. 
Equally important with the problem of coping with the weevil in 
the fields is that of preventing its spread into new territory or, at 
least, since that may be impossible, of giving it as little help as possi- 
ble. Aside from the consideration that the prosperity of each section 
depends largely upor. that of other sections, the spread of the weevil 
from one district 0 others is a distinct detriment to the former as well 
as to the latter in that it increases the distance from which hay for 
feeding purposes must be shipped and consequently increases its cost. 
All commodities which are to be shipped or hauled out of infested 
territory should be kept from contact with growing alfalfa, and they 
‘should at all times be kept away from new alfalfa hay, particularly 
that which has been cut during July and August. 
SUMMARY OF RECOMMENDATIONS. 
The first and second crops of alfalfa can be protected from the alfalfa 
weevil by spraying the young growth in early spring, by proper pastur- 
ing, or by cutting and feeding the crop before the eggs in it have hatched, 
and in a few cases by covering the field with silt in early spring. The 
growth of the alfalfa can be stimulated and a larger yield obtained 
by cultivating the field in the sprmg. The second crop can be pro- 
tected by spraying the stubble or by the dust-mulch treatment. 
Care should be taken to avoid spreading the weevil by shipping 
out of the infested district either new alfalfa hay or articles which 
have been in contact with it or with growing alfalfa.
