Author : SEKENDIZ, O.

Sciapteron tabanifromis Rott. is observed all of the country. It does very important damages especially in the poplar nurseries of Central Anatolia. If larvea attacked to twigs and stems, insecticide applications can not carry out. For this reason the application of insecticides must be repeated 3 or 4 times at intervals of 15 days after the adults left their cocons. Two different sistemics were used for this purpose. The application of insecticide was made starting from the last week of May at Aktehir-Sorkun nursery and the table of analysis of variance was arranged counting the infested plans at the end of the vegetation period. According to these studies the application of the insecticide called Rogor 3 and 4 times gave a sufficient and significative result. But the other insecticide called Metasistox-R was not so sufficient. Therefore it would be sufficient at our nurseries spraying three times with the solution of 100 liters of water and 200 grams of Rogor starting from the last week of May, at intevals of 15 days against Sciapteron tabaniformis Rott. infestations.

Authors: TOLAY, U., VURAL, M.

If the poplar wood which has quite a number of place to be used is kept in pile fo a long period of time after the felling it is infested by many wood decaying fungi. These fungi cause decays in different shapes according to their characteristics of the poplar wood. Within the framework of this project, some fungi species which infest the piled poplar wood were diagnosed and a list of these fungi species were shown as follows : Collybia velutipes Quelet. Lenzites betulina (Lin.ex.Fr.) Pilat. Lentinellus cochleatus (Pers.ex.Fr.) Karst. Poria Sp. Polyporus versatilis Rom. Daldinia concentrica (Bolt.) Trametes gibbosa (Pers.) Fr. Auricularia mesenterica Dick ex Fr.


14) THE EXPERIMENTS ON CHEMICAL CONTROL AGAINST THE PLANT DISEASE OF YELLOW CLOC CAUSED BY Taphrina aurea (Pers.) Fr.

Year /Number: 1968/3                             ODC: 443.3:172.1:176.1.Populus 
AuthorS: TOLAY, U., VURAL, M.

Taphrina aurea (Pers.) Fr. is a fungus which widely infested the poplar hybrids of the regions of Marmara and Trachia and which mostly causes losses on two years old nursery stock for this reason an experiment was designed to study the effect of spraying chemicals against this plant disease on two years old nursery stock of the clone of P.x eurameicana "I-214" at the nursery of the Institute in Izmit. The experiment was taking place some other studies such as the evolution of the disease in related with the climatical conditions and the intensity of the disease were also carried out. The fungiside called Pomarsol gave the best results and Zineb could be used instead of it.


15) SOME INVESTIGATIONS ON STUDY OF Melampsora alli populina Kleb. AND ON THE CHEMICAL CONTROL AGAINST THE RUST DISEASE CAUSED BY THIS FUNGUS THAT ATTACKS P.x. euramericana I-214

The rust disease by Melampsora allii-populina Kleb is quite widely spread in Turkey. To study the control measures of this disease which causes heavy loses on nursery stock, the nursery in Izmit was chosen and P.x euramericana was used for this purpose. In order to eliminate the Teleutospores which play an improtant role in transfering the disease from one year to the other the leaves were mixed with soil by deep plowing the earth. Depending upon this mechanical control the chemical control measures were examined. At the same time the evolution of the parasite in accordance with the climatical conditions, and the intensity of the disease were also examined and the values about them are given. The experiment was designed in the pattern of randomized blocks with 4 treatments (Vitigran, Maneb, Antrocol and Control) and the spray of fungicide was repeated for rour times. The fungicides and their doses applied in this experiment are given in a table. The evoluation was made after the spray and the number of uredospores on leaves counted using a counting cell. The results were analysed by the analyses of variance there is a significant difference among the effects of fungicides at one percent level. In examining the differences among the fungicides the Duncan multiple range test was applied. As it could be understood from this table the fungicide called Vitigran gave the best result, Maneb and Antracol could also be recommended for the same purpose since there is not a significant difference between them from the statistical methods point of view.


16) SOME INVESTIGATIONS ON STUDY OF Melampsora sp. AND ON THE CHEMICAL CONTROL AGAINST THE RUST DISEASE CAUSED BY THIS FUNGUS THAT ATTACKS P.x. nigra 56/52

Melampsora Sp. is one of the most widely distributed fungi in Turkey. It especially infests the native P. nigra types and clones under the conditions of Central Anatolia. We planned to make research on spraying chemicals to make research on spraying chemicals to control this rust disease and the nursery of the Poplar Research Station at Ankara was chosen for this purpose which characterizes the conditions of Central Anatolia. On one hand the expeiment was designed on the clone P. nigra 56/52 and on the other hand the evolution of the disease and intensity of the infection were examined. The experiment was designed in the pattern of randomized blocks with 4 treatments and three different fungicides (Vitigran, Maneb and Antracol) were sprayed for times respectively. The results of this experiments were given in the text. The counting operation was made after the spray of fungicides and counted using a counting cell. As it could be seen from the table of analysis of variance there is a significant difference among the effects of fungicides on one percent level. When the differences among the effects of fungicides were analysed by the Duncan multiple range test it would be seen that Vitigran give the best result. Antrocol could be used secondly, and there is not a significant difference between Antracol and Maneb.


17) SOME INVESTIGATIONS ON STUDY OF Septoria populi Desm. AND ON THE CHEMICAL CONTROL AGAINST THE DISEASE CAUSED BY THIS FUNGUS THAT P.x.nigra 56/52

Authors: VURAL, M., TOLAY, U.

Seprtoria populi Desm. is widely distributed in Turkey and was observed on all the types and clones of P.nigra since a great deal of infection was observed in Central Anatolia the nursery of Poplar Research Institute at KŁtahya was chosen for the experiments which characterizes the climatical conditions of the region. On one hand the experimen was designed on the clone of P.x nigra 56/52, on the other hand the evolution of the disease in related with the climatical conditions and the intensity of the infestation were studied. Since this fungus mostly infests the two-years old plants this experiment was made on two-years old nursery stock which happened to grow from rooted cuttings. The experiment was designed in the pattern of randomized blocks and three different fungicides were sprayed five times respectively. The countings were made using a counting cell. As it could be seen from the table of analysis of variance there is a significant difference on one percent level among the effects of fungicides the Duncan multiple range test was used. The result of this test shows that Antrocol gave the best result, but Thiotex or Cupravit could also be used for the same purpose between which there is not a significant difference from the statistical methods point of view.


18) THE INSECTS WHICH ATTACK EUCALYPTUS IN TURKEY

Year /Number : 1969/4                             ODC: 145.7:176.1.Eucalyptus 
Authors: SEKENDIZ,O., YILDIZ, N.

The most important insects which attack Eucalyptus in Turkey are Hemiberlesia (=Aspidiostus) cyanophylli Signoret. and Phorocantha semipunctata Fabr. Though these insects were observed at present. Their damages have not reached to the seriously limits. If Eucalyptus plantations have not enough irrigation, especially Phorocantha semipunctata attacks are appeared.


19) THE INSECTS ATTACKING FAST GROWING EXOTIC SPECIES

Year /Number: 1969/4                             ODC: 145.7:174.7.Pinus 
Author : SEKENDIZ,O., YILDIZ, N.

This project was based on two insects which attack to fast growing species in Turkey. One of them is Evetria buoliana, the other is Pineus pini. Evetria buoliana damages especially in the young plantations of P. radiata. Pineus pini is at most damages in the P. elderica seedlings.


20) THE INVESTIGATIONS ON THE RESISTIBITY OF THE POPLAR CLONES OF I-214, 45/51, I-418, 64/H, Negrito, Mc (Mellone), 77/51, 70/D, 72/58, 39/16 AT NURSERY AGAINST Melampsora alli populina Kleb. AND Marssonina brunnea (Ell. Et Ev.) P. Magn. UNDER THE CLIMATIC CONDITION OF THE REGION OF MARMARA

Authors: VURAL, M., TOLAY, U.

The fungi called "Melampsora allii-populina Kleb." and "Marssonina brunnea (Ell. et. Ev) P. Magn." have great importance particularly for poplar nurseries. Only one of these fungi may be existing, however, in one nursery, but climatic conditions. The various poplar clones growing at the poplar nursery of Izmit displayed different susceptibility against these two important fungi which attacked to the same clones. The resistability of the clones called 70/D, 64/H, Mc Mellone, Negrito, 72/58, 77/51, 39/61, I-214, 45/51, and I-488 which show good growth in the poplar nuresery of Izmit, have been tested against to these two fungi "Uredosorus" and "Acervulus"have been counted by applying a five windowed cartoon on the leaf surface. According to the results of the analysis of variance, the clones have shown significant differences at the level of P=0.01 the differences between the resistabilities of selected ten poplar clones against these two fungi which infest the leaves have been determined by the test of Duncan summarized as follows : A- The resistabilities of Ten Clones Studies Against Marssonina brunnea (Ell. et. Ev.) P. Magn. : The clone number 77/51, 72/58 and 39/61 are significantly more resistant than the others. According to test results, it is possible to represent these clones in three classes with respect to their susceptibility : I- 77/51, 72/58 and 39/61 II- 64/H and Negrito III- Mc Mellone, 70/D, 45/51, I-488, and I-214. B- The resistabilities 77/51, 72/58 and 39/61 are significantly more resistant than the others also against Melampsora allii-populina Kleb. The other clones have statistically shown no significant differences and been classified in two groups as follows : I- 77/51, 72/58 and 39/61 II- I-488, Negrito, 64/H, Mc Mellone, 45/51, 70/D and I-214.
