  Early blight is an important and ubiquitous disease which attacks many herbaceous plants Specially Solanaceae family. Already this disease threaten the potato fields In Iran. The experiments were conducted in order to study the effects of rovral, Chlrotalonil, Mancozeb fungicides in 1 ppm against flint in 1, 2, 5, 10 ppm on different culture media, including PDA and CMA for two species Alternaria alternata & Alternaria solani. The result indicated that, all of tested fungicides could prevent the growth of two species with the various levels, as far as the growth rates are concerned. Also flint fungicide in various concentrations, 1,2, 5, 10, 20, 50, 100, 200, 500 and 1000 ppm indicated that it could effectively inhibit the growth of two fungal species, as the dosages are increased, indicating the reductions in the growth correspondingly. The highest inhibitions were flint 500 and 1000 ppm and the lowest in flint 1 ppm. This fungicides had a very significant effects on the sporulation of A. alternate, indicated that, with the increased in fungicides concentrations, the sporogenesis decreased, in which the highest sporulation was in Mancozeb treatment and the lowest was in flint with 1000 ppm Also, the results indicated, that the fungicides had effective reductions on the dry and wet mycelial growth weights on zapeks culture media, where the highest wet weights were observed in Mancozeb fungicide, and the lowest was in flint, 1000 ppm.

  Rhizoctonia canker, also known as stem canker and black scurf of potato, Rhizoctonia solani Kuhn, causing serious economic losses by canker on under ground stem, roots, stolens, blanding of tubers and black scurf on potato surfacee in Isfahan. In this manscript, the effects of green chitting and or disinfection of potato seed tubers and soil were considered on this disease in the fields. The laboratory trails on R. solani isolates indicated that, almost all the sclerotinia are pathogenic. The seed tubers of four potato cultivars were selected and kept under room temperature along with normal light and high humidity for two months. Then, they were sown in the highly infested soil to the disease. The results indicated that the green chittings reduced Rhizoctonia stem canker severity effectively. In comparison to the above experiments, the fungicide screening, Rovral in the form of seed, soil and simultaneous seed and soil applications were carried out in the same fields. The results showed that the stem canker severity was reduced effectively compared to chittings and that of control. Increased growth response was observed in only green chitted potato seed tubers compared to other treatments.  Manuscript profile

  اثر پنج قارچ کش و عصاره برگ تازه چای در برابر لکه برگی و آنتراکنوز آزالیا در طول فصل تابستان 1394 در آزمایشگاه دانشکده کشاورزی دانشگاه آزاد واحد رشت مورد آزمایش قرار گرفت. قارچ کش ها در غلظت های 1000، 2000 و 3000 پی پی ام تهیه و به منظور تعیین درصد بازدارندگی از رشد عوامل بیماری زا به کار برده شدند. اثر قارچ کش های مختلف Bavistin 50WP، Dithane M-45، Aliette، Benlate 50 WP و Topsin M 70 WP روی قارچ Pestalotia کاهش قابل توجهی در رشد پرگنه در مقایسه با شاهد به ترتیب با 5/0، 5/0، 5/0 ، 38/3 و 56/2 میلی متر و شاهد 0/88 میلی متر در دوز تجاری توصیه شده 2000 پی پی ام داشت. قارچ کش های فوق کاهش قابل توجهی در رشد پرگنه Colletotrichum داشتند و در هر سه غلظت هیچ رشدی در مقابل سه قارچ کش Mancozeb ،Thiophanate-methyl وFosetyl aluminum مشاهده نشد. با این حال حساسیت قابل توجهی در پاتوژن های جدا شده به قارچ کش های مختلف وجود داشت. غلظت های مختلف عصاره برگ تازه چای مورد استفاده، برای کنترل عوامل بیماری زا فوق هیچ کدام قادر به جلوگیری از رشد کلنی قارچ ها در سطح آزمایشگاه نبودند.
