What would you recommend as an ef- 

 fective remedy for the mite pest in the 

 greenhouses. I have been told by several 

 people to use kerosene, but I am doubt- 

 ful whether it should be applied at full 

 strength, or diluted. Does kerosene af- 

 fect the plants, and are its fumes harm- 

 ful? I should be very glad to have you 

 give me some information on this matter.

(The folloudng replies li'cre received to 

 the above question, which was submitted to 

 prominent members of the gardoiing pro- 

 fession. If other readers of The G.\k- 

 DENERs' Chronicle have had experience 

 ii.nth the mite pest, u-e should be ghd to 

 hear from them. — Ed.) 



Regarding the mite pest, I am not sure 

 exactly what variety of this pest is troubling 

 your correspondent. If it is a cyclamen or 

 begonia mite, kerosene, of course, cannot 

 be used. (Cyclamen and begonia mite in- 

 fest the leaves, and a kerosene solution 

 would be harmful to the leaves.) If it is 

 in wood or floors, kerosene is safe, and the 

 odor will not affect the plant life at all. 

 If I could be advised more accurately of 

 the nature of the mite, I could give better 

 advice. — W. N. C. — Mass. 



If your correspondent will use one wine 

 glass of kerosene to every gallon of water, 

 I am sure he will find it an effective remedy 

 against the mite pest troubling his green- 

 houses. The solution will not prove harm- 

 ful to the plants, if the mite is attacking 

 only the roots, and the solution is applied 

 to the soil.— T. P.— L. I. 



I suggest that your correspondent use a 

 nicotine solution as an effective remedy 

 against the mite pest. Cyanide of potassium 

 is excellent, but is dangerous in the hands 

 of one not skilled in using it. — A. M. — L. I. 



I believe that your correspondent could 

 use a solution of kerosene and water if this 

 is constantly mixed so that the kerosene will 

 not separate: that is, the kerosene rise to 

 the top and the water remain at the bottom 

 of the sprayer. This solution should only 

 be applied to the benches. Especially in the 

 case of cyclamen, where the mite lays its 

 eggs, often on the leaves, this solution could 

 not be used, for the kerosene, unless verv 

 carefully applied, will burn them. I stronglv 

 recommend using nicotine with a little soft 

 .soap dissolved in the solution on the plants, 

 as the soap forms a scum and will aid in 

 smothering the mite, and not permit the eggs 

 to hatch.— J. T.— N. Y.
