%X <p>In 1953 and 1954 needle cast (<em>Peridermium pinastri</em> (Shrad.) Chev., now <em>Lophodermium</em>) caused much damage at the Leksvall nursery at Tammisaari as well as at some other nurseries in Southern Finland.</p>
<p>Experiments were conducted at the Leksvall nursery with different fungicides. The results showed that with spraying done every second week during the whole growing season beginning on May 20th and ending on 27th September in 1954, the damage caused by needle cast was entirely controlled with 2% Bordeaux mixture and the zineb preparation (Dithane Z-78); nabam preparation (Dithane D-14) being somewhat less effective. Lime sulphur, Burgundy mixture, thiram preparation, captan preparation, and PCNB preparation were rather ineffective, in addition, of these the lime sulphur and the Burgundy mixture caused damage to the needles. Phenylmercury preparation proved useless.</p>
