Lime sulphur, and caustic soda without cooking gave satisfactory results, but was 

 not as effective as boiled lime and sulphur. Lime and Bulphur 20 -15 I <>r lime, sul- 

 phur, ami salt (20-15-121 boiled for 45 minutes gave very good result-, and demon- 

 strated anew the effectiveness of this wash. The results obtained from the use of 

 Kill-O-Scale, Con-Sol, scalecide, and horicum were not promising. The author 

 recommends lime and sulphur as the mosl satisfactory spray for San Jose* scale. 

 Wherever possible it is besl to boil the mixture, otherwise a fairly satisfactory solu- 

 tion may be made by the use of caustic soda. 



Formulas arc driven for the preparation of these insecticides. Where only one 

 application is made it is recommended that treatment be postponed as late as possible 

 in the spring. 



The San Jose scale in Mississippi, and the lime-sulphur-salt wash, <l. YV. 



1 [brrick I Mississippi Sta. Bui. 90, pp. t5,figs. 5). — San Jose* scale has been known to 

 occur in Mississippi since L897. 



Lime-sulphur-salt wash is believed to be the best remedy for this pest. A formula, 

 80-15-10-45 is recommended, and the author boiled the mixture for 2| hours. When 

 applied in February during a rain storm the results were not wholly satisfactory, but 

 a second treatment in December destroyed about 90 per cent of the insects. The 

 author states that the mixture can be made satisfactorily by boiling 1 hour. Brief 

 directions are given regarding pumps, nozzles, pruning orchards, summer treat- 

 ment, etc. 



In one case an orchardist was able to hold the scale insect in cheek by severe 

 pruning and painting the branches and trunks with a thick coat of lime-sulphur-salt 

 wash. For summer treatment kerosene emulsion prepared according to the formula 



2 lbs. soap, 4 gal. soft water, and 8 gal. kerosene is recommended. 



Report on work done in 1901-2 in the control of San Jose scale and other 

 dangerous insect and fungus pests, J. H. Stewart ( ]V<st Virginia sta., t90S, 

 pp. 64, pis. 5).— In this report the author presents a financial statement of the dis- 

 bursements and receipts in the work of exterminating nursery ami orchard pests. 

 and also an account of the experiments carried out along this line. 



The purpose of the State law under which the work was carried on was to prevent 

 the introduction of insect and fungus diseases or their further distribution after being 

 Introduced, the inspection of nursery stock and orchards, ami the adoption of meas- 

 ures for eradicating pests. A list is given of the nurseries inspected with notes 

 on the extent of work done. During the years under report 98 orchards, aggregat- 

 ing about 270,000 trees, were inspected. The distribution of San Jose scale was 

 mapped out. 



Experiments were carried out in controlling San Jose* scale by natural enemies, 

 fumigation, and spraying, in orchard work fumigation suffers from several disad- 

 vantages, including expensiveness. inefficiency, and danger. Notes are given on the 

 application of crude oils, whale-oil soap, lime-sulphur wash, potash-sulphur spray, 

 and other insecticides. A Dumber of bulletins previously issued by the station and 

 already noted are included in the report. 



The San Jose' scale, A. M.\< i.ki.i.an [Ann. Rpt. Bd. Agr. R. I., 20 (1904). pp. 

 114-116). — The economic importance of this pest is briefly discussed. As remedies 

 for the San Jose" scale, the author recommends a lime-sulphur-salt mixture contain- 

 in- in lbs. lime, 20 lbs. sulphur, and 15 lbs. salt, as well as other similar formulas.

 discussion of the appearance, life history, habits, and distribution of the gypsy moth 

 with especial reference to suitable means for controlling the pest.
