黄瓜在蔬菜生产和供应中占有重要地位。但因枯萎病发生普遍而又严重,直接影响着黄瓜的产量和品质。据调查,山西吕梁地区一般发病率20~30%,严重地块可达70%以上,特别是保护地黄瓜,由于连作,发病更为严重。为了解决这一问题,1987年在... 黄瓜在蔬菜生产和供应中占有重要地位。但因枯萎病发生普遍而又严重,直接影响着黄瓜的产量和品质。据调查,山西吕梁地区一般发病率20~30%,严重地块可达70%以上,特别是保护地黄瓜,由于连作,发病更为严重。为了解决这一问题,1987年在山西孝义县梧桐乡农科站进行了黄瓜嫁接防病增产技术试验,对嫁接技术、砧木种类选择、亲和性、抗病性、丰产性等进行了研究,取得了明显的效果。 展开更多

[Objective] The aim was to research prevention effects of 25% azoxys trobin suspending agent to cucumber downy mildew.[Method] The test,including control group and four treatment groups with 450,600,and 750 g/hm2 25% azoxystrobin suspending agents,and 80% mancozeb wettable powder,was carried out in 2012 and 2013 consecutively to test the prevention effects of 25% azoxystrobin suspending agent to cucumber downy mildew.[Result] The prevention effects were significant of 25% azoxystrobin suspending agent to cucumber downy mildew in the range of 70.0%-83.6%,and it is recommended 25% azoxystrobin suspending agent at 600 g/hm2 be spread before plants diseased or in initial stage.In the whole stage,it was spread once every 7 d,totaling 3 times.[Conclusion] The research provides references for wide application of 25% azoxystrobin suspending agent in production. 展开更多

Over the few last years, cucumber (Cucumis sativus L) root rot disease became common and inflicted marked losses to yield in Fayoum. Isolation trails from infected cucumber roots revealed that Thielaviopsis basicola and Fusarium moniliforme were the main cucumber root rot pathogens. The isolation trials from the rhizosphere of healthy cucumber plants revealed that two fungal isolates and four bacterial isolates had antagonistic effects against cucumber root rot fungi. All the tested biocontrol agents reduced the radial growth of all the tested root rots fungi in dual cultures. However, all culture filtrates of the tested biocontrol agent significantly reduced radial growth of all the tested pathogenic fungi, except that T. harzianum. Under field conditions, soil treatment with any of T. harzianum and B. subtilis BI and BF, significantly reduced percentages of infected plants and significantly increased percentages of survived plants and fruit yield compared with the control. Application of the commercial product Harpin protein (Messenger)~ product, as a resistance inducer at 0.3, 0.5 and l g/L significantly reduced the percentage of infected plants under greenhouse and field conditions. Field experiments indicated that the average percentage of infected plants after 90 days significantly decreased. The percentage of the survived plants as well as fruit yield increased by using integrated disease management (IDM) package, including the most effective treatments: tolerant cultivar, Trichoderma harzianum granules formula as soil treatment, Purging cassia plant extract, Harpin protein, and a half dose of Vitavax/thiram comparing with the treatment recommended by the Ministry of Agricultural or applied treatments individually. 展开更多
