158 INJURIOUS INSECTS OF 1909 AND IQIO. 
Pests: In dormant season spray with lime sulfur wash. As the 
buds are breaking spray with arsenate of lead and lime-sulfur (self- 
boiled), or with arsenate of lead and Bordeaux mixture. Repeat 
just after blossoms fall. Repeat in two weeks. Repeat at intervals 
of two or three weeks until the fruit begins to ripen and substitute 
ammoniacal copper carbonate for the Bordeaux mixture. 
Asparagus. 
Rust: The most conspicuous stages of the rust appears as 
brown eruptions, followed later in the season by black, or brownish 
black patches of winter spores. 
It has been observed that the disease is most prevalent on dry 
soils, so a good rich soil very carefully cultivated ana kept fairly 
moist renders it less destructive. It is also favored by heavy dews, 
and moist conditions, so there should be good aeration. In the fall 
all diseased stalks should be collected and burned. Spraying has 
been partially successful. Resin bordeaux should be applied at 
intervals of about ten days beginning when the shoots are small. 
However, while shoots are small and rapidly growing, it may be 
necessary to spray more frequently. 
Bean. 
BEAN AND PEA WEEvIL: The beetles usually appear on the 
vines when the plants are in blossom, the eggs being deposited on 
the surface of the young pod. The hatched larvae bore into the 
pod and enter the young seed, where it grows to maturity. In this 
state the pea weevil probably remains within the seed until planted 
the next spring. It does not breed in dry peas. The bean weevil, 
however, will breed in dry beans. For the pea weevil the best 
remedy is to hold the seed over a year before planting, keeping in 
a tight receptacle. Fumigating the infested seeds with carbon 
bisulfide is good. Heat also (130 to 140 degrees F.) will kill the 
insects in stored material. 
ANTHRACNOSE: This produces the familiar reddish brown or 
darker colored sunken spots on pods, stems and leaves. The dis- 
ease gets into the seed and is carried over the winter in this way. 
No seed treatment has been developed, so it is absolutely essential 
to get seed from healthy pods if the disease is to be avoided. It 
spreads only when the plants are wet, so no cultivation should be 
done when there is moisture on the vines. Spraying is of very 
doubtful value; the essential thing is to get seed from healthy pods.
