The Rorists' Review 



jDNa 17, 1020. 



need not be very heavy in either case. 

 When nicotine papers are used one 

 sheet to every 1,000 cubic feet of space 

 will sufl&ce. If hydrocyanic acid gas 

 is employed, one-eighth to one-fourth 

 ounce per thousand cubic feet will kill 

 all of the adults. The use of hydro- 

 cyanic acid gas is not recommended un- 

 less in the hands of a competent fumi- 

 gator, owing to its deadly poisonous 

 effects. Too much emphasis can not be 

 laid on the fact that the fumigation 

 must be set off after midnight to be 

 effective. It is preferable to start the 

 generation between the hours of 12:30 

 a. m. and 2 a. m. Any fumigation done 

 before midnight would be useless, for 

 it has been pointed out that the adult 

 does not emerge until after midnight. 

 On the other hand, if it is started later 

 than 2 a. m. many adults will have 

 emerged and laid their eggs. 



' ' In case fumigation is not advisable, 

 especially where chrysanthemum plants 

 are isolated or. when other varieties of 

 plants are present in the houses, spray- 

 ing is recommended. This must be done 

 consistently for a period of four to six 

 weeks, a forty per cent solution of nico- 

 tine sulphate extract diluted (1-800) 

 being used, and soap added at the rate 

 of one-half to one ounce per gallon of 

 solution. The application should be 

 made late in the afternoon in order that 

 the best results may be obtained. In 

 this manner practically all adults can 

 be killed at the time of emergence and 

 any eggs present will be destroyed. 



Preventive Measures. 



"It has been proved that the means 

 of disseminating this insect has been 

 the shipment of infested chrysanthe- 

 mums, both plants and cuttings. It is 

 therefore imperative that only clean 

 plants and cuttings be brought into com- 

 mercial houses where chrysanthemums 

 are growing or to be grown. Growers 

 should carefully examine all chrysan- 

 themums received and see that all ma- 

 terial intended for shipment or distribu- 

 tion is free from this pest. 



" As a preventive measure, it is recom- 

 mended that cuttings be dipped in the 

 following solution at the time they are 

 taken : 



Nicotine sulphate, forty per cent part 1 



'^gt^r parts 800 



Laundry 'soap ounce per gallon %-l 



"Another satisfactory method of se- 

 curing chrysanthemum cuttings free 

 from midge when the previous season's 

 stock has been infested is to plant the 

 stocks in benches or coldframes directly 

 after the season's crop has been re- 

 moved. This should then be followed by 

 thorough treatment with a mixture con- 

 sisting of equal parts of dry or air- 

 slaked lime and tobacco dust. It ifl 

 advisable to keep all new growth cov- 

 ered with the mixture until further op- 

 erations in the spring." 



Cedar lUipids, la. — The peony beds of 

 Charles Billau were damaged to the ex- 

 tent of more than $100 recently by 

 vandals. One of the bushes that was 

 destroyed was a variety for which Mr. 

 Billau has waited for more than two 

 years for a bloom in order to identify it. 



Valencia, Pa. — G. L. Curry & Sons 

 are going into the rooted cutting and 

 seedling business. This firm's green- 

 houses were full of stock for spring 

 sales; it cleaned up well at a good 

 price. G. L. Curry has been ill since 

 March 1, first with stomach trouble and 

 now with rheumatism.
