Spraying gives promising results on alsike clover fields, but is not 

 recommended for red clover. The most satisfactory spray used 

 consisted of 1 part Blackleaf 40 to 1,400 parts of water or | pint to 

 150 U. S. gallons, 4 lb. of dissolved laundry soap being added to each 

 100 gals, of solution. This was applied with a power sprayer.

 State Bd. Entoti}., Knoxville, viii, no. 3, Bull. 30, September 1919, 

 17 pp., 4 plates, 8 figs. [Received 4th May 1920.] 



The author's experiences in controlling the strawberry weevil 

 [Anthonomus sig.natus] in Tennessee during 1915 and 1916 are recorded. 

 An account is given of the life-history and habits of the weevil. The 

 method of control by means of sulphur-lead arsenate dust is discussed 

 [R.A.E., A, V, 287]. While working on this insect in Minnesota, 

 it was discovered that the weevils are unable to emerge when covered 

 over with soil ; apparently therefore by ploughing under old, infested 

 ]>atches the weevils can be successfully buried. On badly infested 

 fields the one-crop system should be followed to avoid severe injury, 

 or, if the weevils are not too numerous on the buds, the two-crop 

 system may be practised. Soon after picking the beds should be 

 mowed and the leaves and weeds should be burned over quickly, 

 as a creeping fire injures the plants. The rows should then be narrowed 

 to strips 4 to 8 inches wide. Where the beds are burned over and 

 cultivated, it is seldom that any weevils are left. More than two 

 crops should never be taken from the same field and old, neglected 

 patches should not be tolerated as they serve as a breeding-ground 

 for the weevils.

Crops. — Virginia Truck. Expt. Sta., Norfolk, Va., Bull. 28. 1st 

 July 1919, pp. 83-98, 6 figs. [Received 4th May 1920.] 



This paper describes the various equipments necessary for the 

 effective application of sprays for different vegetable crops. The 

 particular kind of " boom," i.e., the structure that conducts the spray 

 material to, and supports, the nozzles, that is adaptable to a special 

 crop such as tomato, potato, spinach or kale, is discussed, and the 

 construction of suitable ones is described and illustrated. The con- 

 necting of these booms to existing machinery is explained, and their 

 cost has been approximately worked out.

 logist, Univ. Farm. St. Paul. Minnesota. Circ. 52, 1st April 1920, 

 8 pp., 13 figs. 



Cutworms are among the worst pests that the farmers and gardeners 

 iti Minnesota have to contend with ; some instances are given of 

 serious losses in the State due to them. The usual methods of pro- 

 tection against these pests are discussed, the best means of prevention 

 of attack' being by general clean cultivation. Other methods include 

 autumn ploughing, stiff paper collars round the young plants, and 

 the use of poisoned bran mashes. Hand-picking and digging out the 

 caterpillars are also advocated.
