866 INSECTICIDES, FUNGICIDES, AND WEED KILLERS. 



and injurious insects. The first spraying was made with a solution 

 of Oo per cent, from 20-30 April. The second with 0-7 per cent 

 solution from 1-8 May. The third with 0-1 per cent solution from 

 1-8 June. Solutions of 0-5 per cent are very injurious to young 

 shoots, and 1 per cent solutions burn them ; but adult leaves stand 

 these strengths better and are not burned, except by those above 2 per 

 cent. To increase the adherence of this product it has been advised 

 to make a bouillie of 1 lb. of " lysol," 2-3 lb. of plaster, and ^ lb. of sili- 

 cate of soda of 33° B., in 10 gallons of water. The French " Lysol " 

 company sells a "lysol" powder recommended against mildew, which 

 must be used in the morning before the dew disappears. 



Phytophthora infcstans, De By. (potato disease).— Sturgis declares 

 after experiments to disinfect potatoes with " lysol " that it cannot re- 

 place corrosive sublimate. "Lysol" in 1 per cent solution injures 

 potatoes in one and a half hours' steep. Its action on the spores is nil. 



Fusarium. — Mangin advises against fusarium to disinfect the soil 

 with " lysol " in place of corrosive sublimate. 



Guifjnardia Bidivelli, Viala et Eavez (black rot of the vine). — 

 Fernbach has studied the action of " lysol " on black rot. He records 

 the good condition of a vine coated in winter with a 3 per cent " lysol '' 

 solution and twice sprayed (1) with a 0-5 per cent solution at the be- 

 ginning of vegetation, (2) with a 0'7 per cent solution at the end of May. 

 Black-rotted leaves steeped in a 1 per cent solution for five minutes, 

 then washed and put in contact with a healthy leaf, no longer conveyed 

 the disease to the latter. It was the same with black-rotted leaves 

 placed in contact with a healthy leaf previously sprayed with a 1 per 

 cent preventive solution. Spraying and powdering done from bottom 

 to top, so as to reach the lower face of the leaves on which the parasites 

 preferably develop, arrest the disease in its evolution. Dieulafe advises 

 to overcome black rot : (1) The spraying of the stems, the runners, and 

 the pruning wounds with a solution of 2-5 per cent of "lysol," done 

 in winter at the time of pruning. (2) Spraying at the time ol coming 

 out in leaf of the buds with a solution of 0-5-1 -0 per cent. (3) Dusting 

 from April to August in moist weather with " lysol " powder. 



Mycogoue perniciosa (mole disease of the mushroom). — Constan- 

 tine and Dufour recommend "lysol" in 2 per cent solution for the dis- 

 infection of the frames. The process which consists in disinfection of 

 the whole frame, as much of the soil as of its sides, gives better results 

 than treatment with blue vitriol, boric acid, or bisulphite of lime and 

 sulphurous acid. It prevents or overcomes other diseases of the mush- 

 room such as the Y>\a.steY {Moniliafumicola) , gout (bacterian disease), etc. 



Nectria ditissivia, Tul. (canker of fruit trees). — Schiller remarks 

 that canker of fruit trees is cured quicker by " lysol " than by tar. 



Coating Trees in Winter against Insects.— Mathieu instead of 

 liming the trunks, coats tliem with a solution of \ lb. "lysol" in 1 

 gallon of water. 



Charceas graminu (antler moth or grass moth). — Eeuter effectually 

 destroyed the caterpillar of this noctua by watering the meadows with 

 a 2 per cent solution of " lysol " when it begins its ravages. " Lysol " 

 is regarded as less energetic against the caterpillars which live pro-
