Formerly trunk rot of apple(Botryosphaeria ribis Gross,et Dugger)was reported onlyoccuring on young trees.Since 1957 it was noted to be one of the serious diseases on matureapple trees in the southern part of Liao-ning province,where the disease developed from themiddle of May to the end of October.There were two peaks of development in a year(i.e.June and August),during which the cankers extended most rapidity.Wounds and lenticelswere found to be the principal entrances of the fungus.The rate of infection reached...

Formerly trunk rot of apple(Botryosphaeria ribis Gross,et Dugger)was reported onlyoccuring on young trees.Since 1957 it was noted to be one of the serious diseases on matureapple trees in the southern part of Liao-ning province,where the disease developed from themiddle of May to the end of October.There were two peaks of development in a year(i.e.June and August),during which the cankers extended most rapidity.Wounds and lenticelswere found to be the principal entrances of the fungus.The rate of infection reached 62.7%at the points where the bark was injured.Topography was also an influencing factor.Lim-sulfur spray proved to be fairly effective among the nine fungicides tested.Four applica-tions of lime-sulfur in the growing season reduced the trunk rot to less than 50%.Cuttingoff infected tissue or banks was considered as a less effective operation.

根据1960—1961年的研究,苹果干腐病在辽宁省,每年从5月中旬到10月均能发生为害,6月分为发生发展的第一次高峯;8月下旬至9月上旬为第二次高峯。苹果干腐病的发生与气候条件有密切关系。干旱与积水均能诱发病害的发生,而干旱的影响最大。地势与发病亦有影响,低洼地发病较重。树势强弱与本病的发生有密切关系。栽培管理条件好,树势旺壮者,病势一般较轻。喷药保护树干有一定作用,彻底刮治病斑,再涂抹石灰硫磺合剂,效果很好。

The needle-cast disease of Laricis leptolepis caused by the fungus Mycosphaerella laricileptolepis Ito, Sato, and Ota, is widely distributed in North-East provinces. The primary infection of the pathogen is mainly the ascospores from the fallen leaves on the ground during the spring. In order to determine the distance of its vertical and horizontal discharge of the spores from the perithecia, a simple spore-trapping method was designed by exposing the glass slides in six directions, placed in three different...

The needle-cast disease of Laricis leptolepis caused by the fungus Mycosphaerella laricileptolepis Ito, Sato, and Ota, is widely distributed in North-East provinces. The primary infection of the pathogen is mainly the ascospores from the fallen leaves on the ground during the spring. In order to determine the distance of its vertical and horizontal discharge of the spores from the perithecia, a simple spore-trapping method was designed by exposing the glass slides in six directions, placed in three different locations and six different heights. Preliminary data showed that the ascospores could reach a height of 55 meters and a distance of 1600 meters along the wind direction. Among the 20 fungicides tested in the field on both young and large trees, 0.5°Bê limesulphur spray employed three times at 2-weeks interval gave a very good control. A ground spray on fallen leaves by six different fungicides did not give satisfactory results although 3°Bê lime-sulphur and lime (20 grams per tree) appeared to be better than dinitro-phosphatemethyl-phenol.

落叶松早期落叶病子囊孢子在空中的扩散,在长春地区,以7月份为盛期。林外水平距1600米及垂直高55米处均可捕捉到不低于林内孢子的数量,其方向符合夏季主风方向。噴药防治的效果,无論成林或幼林,均以0.5度石灰硫黄合剂最好,尤其噴药3次的更佳。地面噴药抑止产生子囊壳,以3度石灰硫黄合剂及每株20克石灰比二硝基磷甲酚效果好。

The head smut[Sphacelotheca reiliana(Kühn)Clint.]of corn is oneof the most important diseases in Bai-Cheng region of Jilin province.The percentage of smut plant is usually about 3-5%,and sometimesover 30%.The symptoms besides the ordinary stunting,rosetto andpolystooling were observed.The smut balls occur mostly on ears andsometimes on both ears and tassels.Chlamydospores collected from natural dissemination showed a highpercentage of germination,but those collected from inner part of thesorus were low in germination.Although...

The head smut[Sphacelotheca reiliana(Kühn)Clint.]of corn is oneof the most important diseases in Bai-Cheng region of Jilin province.The percentage of smut plant is usually about 3-5%,and sometimesover 30%.The symptoms besides the ordinary stunting,rosetto andpolystooling were observed.The smut balls occur mostly on ears andsometimes on both ears and tassels.Chlamydospores collected from natural dissemination showed a highpercentage of germination,but those collected from inner part of thesorus were low in germination.Although it might be carried on seed-coat yet soil transmission is considered to be the main mode of dissemi-nation since the chlamydospores maintained their vitality in soils forthree years.Higher infections might be obtained from the contaminatedsoil.Infections in seedling stage occurred abundantly until 4 leaf stage,and actually decreased since the starting of the 5 leaf stage and noinfection took place at leaf stage.Head smut fungus from corn did not infect sorghum.On the cont-rary corn plants were to be infected by sorghum head smut with a lowrate.The chlamydospores thus produced from corn plants lost the abi-lity to infect sorghum,however infected corn in an increasing rate.Itmight be due to the different physiological races in the smutinoculum.The head smut fungus collected from Shanxi and Xinjiang were weakin pathogenicity and those from Liaoning and Jilin are strong.More than 200 inbred lines and hybrids had been tested for theirresistance to head smut in field plots.The high resistant varieties werealmost immune.The resistance of maternal plants had more importantinfleunce to next generations.Over hundred fungicides tested for seed treatment,a few of themshowed 70% controlling effects and were not stable in different years.Most fungicides only showed 50% controlling effects.

玉米丝黑穗病是白城地区的重要病害,一般发病率为3—5%,重者高达30%以上,是生产上急待解决的问题。其症状以正常型为主,有时出现矮化型、矮化丛生型和多分蘖型等特异症状。病株以雌穗为黑穗、雄穗为健穗及雌雄穗皆为黑穗者居多。病穗上自然脱落的厚垣孢子萌发率高,病穗内的萌发率明显降低。此病为系统侵染病害,种子及土壤均可带菌传病,以土壤带菌为主,属土传病害。厚垣孢子在土壤里能存活三年,土壤带菌量越多,菌土覆盖种子越厚,发病率越高。丝黑穗病菌侵染玉米幼苗时间较长,从种子萌芽到四叶期最易侵染,五叶期后,侵染明显下降,八叶期后不再侵染。在幼苗叶片上接菌不能侵染致病。玉米丝黑穗病菌不能侵染高梁。高梁丝黑穗病菌能侵染玉米,但侵染率甚低。侵染玉米后的病菌,不再侵染高梁,只侵染玉米,且致病力明显增强。两菌是同一菌种的不同生理型。用来自九个省、市的丝黑穗病菌接种于不同抗性的自交系鉴定寄主,其致病力不同,陕西和新疆的致病力弱,辽宁和吉林的致病力强。在田间人工接种条件下,鉴定了二百余份自交系和杂交种的抗病性,品种间有明显差异,高抗的近于免疫,高感的发病率在90%以上。抗病性遗传规律表现为双亲高抗的,其后代亦抗,以母本的抗病性起主导作用。选...
