Strawberry Culture ^j~ 



mid pure pyrethrum, mixed with four times its weight of common 

 wheat flour, applied to the plants, with a bellows made for the 

 purpose or I^eggett's " Powder Gun," early in the morning when 

 the dew is on and the bugs are not active. Or the pyrethrum 

 may be mixed with hot water at the rate of one pound to fifteen 

 gallons, stirred till it cools, and be applied early in the morn- 

 ing with a spray pump, using a "Bordeaux" nozzle. In either 

 case the leaves must be moved aside with one hand so that the 

 blossoms and young fruit .may be reached. Do not use poisons, 

 as they are likely to poison the fruit and will not hurt the bugs. 



STRAWBERRY LEAF-ROI^ER (Phoxopteris comptana) The 

 following is taken in condensed form from Bulletin 176 of the 

 Michigan Station, prepared by Mr. Rufus H. Pettit in 1898: 

 * ' The caterpillars are small yellowish or green 'worms, ' which 

 feed on the leaves and cause them to curl up tightly into little 

 clumps which are then bound together with a silken web. The 

 caterpillars or larvse may be found usually by pulling apart some 

 of the curled leaves. They vary in color from pale yellow to quite 

 a decided green, and when full grown are about one-third of an 

 inch in length, slender and gently tapering. The adult winged 

 form, not seen so often, is a very small and delicate moth, reddish 

 brown and dusky in color, with black and white markings and 

 about one-fourth of an inch in length, while the extended wings 

 measure a little less than half an inch." The first brood of cat- 

 erpillars appear in June, the second late in the fall. 



Remedies. For the June crop spray with kerosene emulsion, 

 long enough before the fruit ripens to give the oil time to evap- 

 orate. After bearing, mow the bed and burn it over. Then 

 spray with Paris green and lime, repeating as long as any cater- 

 pillars appear.
