No. | SWEETCLOVER PEST CAN NOW BE CONTROLLED 
Farmers who have depended upon sweetclover as their principal 
soil improvement legume or for other uses can now breathe a sigh of 
relief. The principal enemy of this crop, the sweetclover weevil, can 
be controlled. This insect has spread throughout the Corn Belt and 
into other areas where sweetclover is grown. 
j The adult weevil, a small, slender, dark-gray snout beetle about 
= 3/16 inch long, comes out of hibernation in the Corn Belt in mid- 
_ April or earlier. It first attacks second-year clover and then moves 
on fo young sweetclover seedlings, devouring the seedling growth as 
_it becomes available. It is most active during warm rainy weather. 
The eggs are laid below the soil surface near the base of the 
plant from early May to beginning of hot weather in June. The adults 
emerge in late July and August and attack sweetclover plants, strip- 
ping them of leaves, and continue to feed until cold weather. 
The object of control is to protect young sweetclover early in the 
spring from attacks of the adult weevil, so that it can get a good 
__ start. The farmer should be on the alert for early signs of injury in 
fe old sweetclover fields, as the weevils will then do severe damage to 
i, any nearby newly-seeded sweetclover as soon as it appears. 
Be rm Cultural practices which help control sweetclover weevil are to 
_ delay seeding until June and to avoid seeding adjacent to second-year 
stands. Effective chemical control consists in application of DDT as 
As a spray, use 1 gallon of 25 percent DDT in 20 gallons of 
water per acre. Apply when sweetclover is in 2-leaf stage and when 
nearly Y of leaf surface has been destroyed but not later, and be 
sure to spray the sweetclover plants. Earlier spraying may waste time 
and material and delay may result in destruction of crop. 
The Indiana station recommends dusting a DDT-superphosphate 
mixture to the sweetclover in the very early seedling stage. Mix 
THOROUGHLY 4 pounds of 50 percent or 20 pounds of 10 percent 
DDT with 200 to 400 pounds of 20 percent superphosphate per acre. 
_Apply soon as possible after mixing. Best stands are obtained by ~ 
this method because the DDT kills the weevils running along the ground 
and the fertilizer stimulates the plants so they are not so easily killed 
by the weevils. 
Care should be taken not to apply DDT to foliage likely to be 
eaten by milk cows or animals being fed for slaughter. There should 
be no risk, however, in applying DDT to sweetclover seedlings as out- 
lined above or to sweetclover to be plowed under as green manure. — 
Sweetclover is the cheapest soil-building 
legume in seed cost for 1952 planting. 
Its value in increasing yields of subsequent crops, such as corn, 
is well-established. News of control of its chief enemy will be most 
welcome in those sections where some curtailment of use has followed 
the inroad of this pest.
