572 Report of Entomologists op the 



Re^nedial Measures. 



Under tlns^liead we will briefly mention some of the remedies 

 which may be applied if the beetles become established in a field, 

 or which may be used in connection with the protectors. 



Dry wood ashes and air-slaked lime are successfully used in various 

 sections of Long Island as remedies against the cucumber beetle. 

 Concerning these remedies Mr. "Wm. A. Fleet, of Citchogue, L. I., 

 writes me as follows : " The remedy most used here (for the cucum- 

 ber beetle) is dry wood ashes applied when the vines are wet. or 

 air-slaked lime is also good. Either of these remedies will keep off 

 the beetles if applied frequently and the heetles are not allowed to 

 get there first. If the beetles should become established, however, 

 a very little turpentine mixed in the ashes will usually drive them 

 oft'. Care must be taken not to use too much turpentine. A table 

 spoonful to a peck of ashes is plenty." The ashes or lime should 

 be thoroughly applied. Every leaf should be covered and frequent 

 applications made if the beetles are numerous. 



Paris green and plaster have been used with much success. 

 This is an old remedy. The Paris green and plaster should be 

 mixed in the proportion of about one part of the poison to twenty 

 parts of plaster. Apply when the vines are wet. In order to show 

 how effectual this remedy has been the following is taken from Prof. 

 J. B. Smith's report for 1890, page 482,* The experiments were 

 made under his direction by Mr. F. J. Kroboth, who reported as 

 follows : " Scattered among 118 hills (three or four vines each) of 

 musk melon, I have left ten hills to take their chances with the 

 bugs; the remaining 108 I have treated according to your directions. 

 The untreated hills are now totally destroyed by the striped bug and 

 what appears to be its larva, a small worm entering the stem near 

 the root and working down * * * Driven from the melons 

 they are to be found among my late cabbages, beans, tomatoes and 

 Qgg plants apparently doing little or no harm. The treated hills are 

 all doing well, having melons nearly ripe." Paris green may also 

 be mixed with water, one pound of the poison to 150 gallons of 

 water, and the mixture applied in a fine spray, Newly slacked 

 lime, at least as much by weight as there is Paris green, should be 

 added to prevent burning the foilage. 



Pyrethrum when properly applied has been found a good remedy
