Show Fungicides Tested By Vegetable Mice Scales of Easter lily bulbs are very subject to attack by a fungus: causing scale rot, which accounts for their adoption by Drs. W. D. Mc-1 Chilian and N. W. Stuart, U.S.D.A.' agricultural research division, In determining de-termining the effectiveness of vari-l ous fungicides at the Beltsville sta-' tlon. , One fact that makes these "vege-i table mice" particularly useful inj testing work is that all the scales from one bulb are genetically the I j - "i t I The Easter lily with from 40 to 60 scales of almost china-like smoothness smooth-ness Is well adapted to Its "mouse" role In testing of fungicides. same, and for that reason the vulnerability vul-nerability to attack of the rot is uniform. uni-form. Some other advantages of this new method are that the scales can ba used at any time of the year if properly prop-erly handled, the effect of the disease dis-ease attack on the scales can be read with ease because they are smooth and almost white, the chemical chem-ical to be tested can be applied as dust and in a suspension or solution, the equipment is simple and takes little space. |
