发布者:admin 发布时间:2012/3/19 22:08:42 阅读:8385

辣椒疫病
  发病特征:   在整个生育周期皆可发病,苗期染病,多发生于茎基部,苗期发病,茎基部呈暗绿色水浸状软腐或猝倒,即苗期猝倒病;有的茎基部呈黑褐色,幼苗枯萎而死;叶片染病,病斑圆形或近圆形,直径2~3厘米,边缘黄绿色,中央暗褐色;果实染病始于蒂部,初生暗绿色水浸状斑,迅速变褐软腐,湿度大时表面长出白色霉层,即病菌孢囊梗及孢子囊,干燥后形成暗褐色条斑,病部以上枝叶迅速凋萎。   发病规律:   病菌以菌丝体、卵孢子在土壤中或病组织中越冬,卵孢子借助雨水、灌溉水溅射传播,病菌发育最适温为23℃~31℃,高温高湿有利于病菌发生。   防治方法:   1.若辣椒疫病是土壤传染,防治时必须用农药灌根。   2.防治的关键时间为6月中、下旬?辣椒开花盛期挂果期,一般为浇完头水后1~2天内进行灌根。   3.有效农药用25%早霜灵或58%早霜灵锰锌,浓度为500倍液灌根,每穴灌0.3~0.4斤效果最好。
辣椒白粉病
  发病特征    辣椒白粉病由子囊菌亚门真菌鞭靼内丝白菌引起,叶片,老叶、嫩叶均可染病。在田间主要靠气流传播蔓延。稍干燥条件下该病容易流行。病叶正面初生褪绿小黄点,后扩展为边缘不明显的褪绿黄色斑驳。病部背面产出白粉状物,严重时病斑密布,致使全叶变黄,大量脱落形成光秆,严重影响产量和品质。   防治方法   1.种植时选择抗病性较好的品种并用新高脂膜拌种(能驱避地下病虫,隔离病毒感染,不影响萌发吸胀功能,加强呼吸强度,提高种子发芽率)。   2.种植前深翻土壤,喷洒新高脂膜800倍液杀菌消毒、保温保墒。   3.在辣椒的各个生长期要适时喷洒辣椒壮蒂灵,增强体内营养输送,提高辣椒对外界病菌的抵抗力。   4.发病初期喷洒多氧清1000倍液加杜邦福星3000倍液并加施新高脂膜,效果尤好。

Pepper phytophthora blight

Incidence characteristics: throughout the reproductive cycle can onset, seedling disease, multiple occurrence of Yu Jingji department, seedling disease, stem base dark green water, soft rot or cataplexy, i.e. seedling damping-off; some stem base was dark brown, seedling wilt die; leaf infected disease, circular or nearly circular, diameter 2 ~ 3 cm, margin yellowish green, central dark brown; fruit disease begins with the pedicle of the dark green, water spots, rapid brown soft rot when humidity is big, grow white mold surface layer, namely the germs sporangiophore and sporangia, dries to a dark brown stripe, above the rapid wilting foliage disease. Pathogenesis: bacteria to mycelium, egg spores in soil or disease tissue in winter, with rain water, irrigation water of oospores of sputtering spread of bacteria growth, the optimum temperature of 23 to 31 DEG C, high temperature and high humidity beneficial bacteria occur. Control method: 1 if the hot pepper epidemic disease is a soil infection, prevention must use pesticide root irrigation. 2 the key to prevent and cure time is 6 months late,? The flourishing period of pepper blossom fruiting period, usually poured water after 1 ~ 2 days to fill the root. 3 effective pesticide use 25% or 58% early frost frost Ling Ling MZ, concentration of 500 times fluid to fill the root, each hole irrigation 0.3 ~ 0.4 jins effect best.

Pepper powdery mildew

The pathogenetic characteristics of pepper powdery mildew by ascomycetes fungi within the subphylum whip and white silk caused by bacteria, leaf, old leaves, leaves can be infected. In a field by the airflow spread. Slightly dry conditions in the disease epidemic. The leaf is born chlorotic yellow dots, later extended to the edge is not clear chlorotic yellow mottle. Disease of back output powder, serious when the lesion is densely covered, causing the whole leaf yellowing, large shedding light straw, affects the yield and quality of. Control method of 1 planting time selection for disease resistance varieties with better and with high lipid membrane dressing ( can repellent underground pest, isolation of the virus infection, does not affect the germination of imbibition function, strengthen the respiratory intensity, improve the germination rate of the seeds ). 2 deep turn the soil before planting, spraying high lipid membrane 800 times liquid sterilization and disinfection, heat preservation of soil moisture. 3 in the hot pepper each growth period should timely pepper spraying strong pedicle spirit, enhances in vivo nutrition delivery, improve the pepper on the outside of pathogen resistance. 4 early onset multiple oxygen spraying cleaning liquid and Dupont star 1000 times 3000 times liquid and applied the high lipid membranes, the effect is good.
