The leaf rust of Davids European Aspen caused by Melampsora larici-tremulae Kleb. is one of the most damaging forest tree diseases in Europe and Asia. The spermatia and the aeciospores of pathogen emerge from the leaf of larch, the urediospores from beneath the poplar's leaf and the teliospores from the hypodermis of poplar's leaf. The basidiospores can produce secondary basidiospores after germination, the latter can produce secondary basidiospores and small spores yet again. The optimal temperature for germination of various spores is separately as follows: aeciospores 12℃, urediospores 8-12℃, teliospores 12-15℃ and basidiospores 9-18℃, all of them need 100% humidity for germination. The basidiospores produced from the teliospores over winter are primary infectious source for Larch, and the aeciospores produced from Larch are primary infectious source for Davids European Aspen. The urediospores over winter can not germinate, therefore, there is not infectious ability to trees. Under artificial inoculation, the period of reproduction of various spores of pathogen is separately as follows: basidiospores 10 days, aeciospores 10 days snd urediospores 6-12 days. The basidiospores of pathogen can infect Larix gmelini, L. leptolepis, L. olgensis, L. principis-rupprechtii and L. sibirica. The aeciospores can infect the species and variety species of section Leuce, and can also infect the hybrids between this section or the hybrids taking this section as female, but can not infect the species of section Aigeios and section Tacamahaca and the hybrids in or between these two sections.

山杨叶锈病广泛分布在欧洲及亚洲各国。病原菌为松山杨栅锈菌[Melam—psora larici-tremulae Kleb.],性孢子及锈孢子产生于各种落叶松上,夏孢子生在山杨叶背面,冬孢子埋生在叶下表皮下,担孢子萌发后产生次生担孢子,后者还能产生次生担孢子和小型孢子。各种孢子的萌发适温:锈孢子为12℃,夏孢子8—12℃,冬孢子12—15℃,担抱子9—18℃。各类孢子萌发都需100%相对湿度。过冬后冬孢子萌发产生的担孢子为侵染落叶松的初侵染源,落叶松上产生的锈孢子是侵染山杨叶的初侵染源,过冬后的夏孢子均不能萌发,因而无侵染力。在人工接种的条件下,各类孢子的繁殖期:性孢子为10日,锈孢子10日,夏孢子6—12日。担孢子侵染兴安、长白、日本、华北、西伯利亚落叶松叶,锈抱子侵染白杨派的种和变种、派内杂交后代、以白杨派为母本的杂交后代,但不侵染黑杨派、青杨派以及二派内或派间杂交后代。

The needle rust of korean pine is a common disease in the forest region in Yichun of Heilongjiang province. It mainly harms the needles of young trees which are under the age of fifteen. The pathogenic fungus is identified as Coleosporium saussureae Thiim. Needle rust doesn't cause pine trees to die, but does reduce the growth rate of young trees. Pathogen requires an alternate host to complete its life cycle.The spermatic and aeciospores of pathogen emerge from the needle of Pinus koraiensis Sieb et Zuce. The...

The needle rust of korean pine is a common disease in the forest region in Yichun of Heilongjiang province. It mainly harms the needles of young trees which are under the age of fifteen. The pathogenic fungus is identified as Coleosporium saussureae Thiim. Needle rust doesn't cause pine trees to die, but does reduce the growth rate of young trees. Pathogen requires an alternate host to complete its life cycle.The spermatic and aeciospores of pathogen emerge from the needle of Pinus koraiensis Sieb et Zuce. The urediospores and teliospores live on the beneath of Saussureaes leaves. The basidiospores produced from dangniam teliospores are primary infection sources for korean pine. Thespreading perion in woods for aeciospore is from the middle of May to the middle of June. The climax of the spreading period is the first ten day period of June. The temperature available for germ of various spores as follows:aeciospores 10—27℃; the optimum temperature 25℃,urediospores 20--30℃, the optimum temperature 22℃,basidiospores 10--25℃, the optimum temperature 20℃. The early spring is an opportune moment to prevent and cure the disease. The best chemical to control is lime sulfar and then ambam tuzet.

红松松针锈病是黑龙江省伊春林区普遍发生的病害,主要为害15年以下的幼树,病原菌是凤毛菊鞘锈菌。松针锈病不能至死幼苗,但降低幼苗的生长率。病原菌是转主寄生的,性孢子和锈孢子寄生于红松针叶上,夏孢子和锈孢子寄生于凤毛菊叶背面。当年冬孢子萌发产生的担孢子是红松的初侵染源。在林中锈孢子的放散期是5月中旬至6月中旬,6月上旬为放散期盛期。各种孢子的萌发温度:锈孢子10℃—27℃,最适温度25℃,夏孢子20℃—30℃,最适温度22℃,担孢子10℃—25℃,最适温度20℃。早春是病害防治适宜时机,最好的药剂是不硫合剂,其次是代森铵,退菌铵。
