摘要
试验了三种生物农药Biowilt-X(以哈兹木霉为基料)、Bionem-X(以衣原孢子Pochonia为基料)和biocu - x(以枯草芽孢杆菌为基料)对鹰嘴豆枯萎病(镰刀菌)、根结病(不知名的根结病)和枯萎病复发菌(不知名的镰刀菌+不知名的镰刀菌)的防治效果。bg - 256)。该生物农药采用美国和印度专利新技术开发,分别应用于种子(5 g/kg种子)和土壤(40 g/小区),在田间条件下评价其对目标病害的防治效果。土壤施用多菌灵1.25 kg a.i./h,土壤施用多菌灵6.0 kg a.i./h,种子处理2g/kg。在单独或同时侵染病原菌的地块上生长的鹰嘴豆出现特征性的萎蔫和根结症状,产量显著下降。生物农药的施用抑制了病害的严重程度和由此导致的产量下降。施用Biowilt-X可使枯萎病发病率降低60%,使鹰嘴豆产量提高46%。生物农药Bionem-X和biocu - x对鹰嘴豆根结病的防治效果较好,对根结病的抑制作用分别为20%和12%,对鹰嘴豆的产量提高了28%和34%。应用Biocure-X对真菌线虫枯萎病复合体有很高的防治效果;其种子处理能有效地控制枯萎病和根结病,并能提高49°C伴随感染鹰嘴豆的产量。与其他处理相比,Biocure-X在增加结瘤方面更有效。多菌灵和奈玛库在防治青枯病、根结病和病复方面的效果显著(P < 0.05),但不如生物农药。本研究表明,开发的生物农药可以成功地实现对青枯病、根结病和病害复合体的生物管理。
Efficacy of newly developed biopesticides for the management of wilt disease complex of chickpea (Cicer arietinum L.)
Effectiveness of three biopesticides viz., Biowilt-X (based on Trichoderma harzianum), Bionem-X (based on Pochonia chlamydosporia) and Biocure-X (based on Bacillus subtilis) were tested against wilt (Fusarium oxysporum f. sp. ciceri), root-knot (Meloidogyne incognita) and the wilt disease complex (F. oxysporum f. sp. ciceri + M. incognita) of chickpea (cv. BG-256). The biopesticides were developed by involving novel technology patented in USA and India and were applied to seeds (5 g/kg seed) and soil (40 g/microplot) to evaluate their effectiveness against the target diseases under field conditions. The pesticides viz., carbendazim and nemacur were applied @ 1.25 kg a.i./h and 6.0 kg a.i./h as soil application, and 2g/kg seed as seed treatment. Chickpea grown in the plots infested with pathogens singly or concomitantly developed characteristic wilt and root-knot symptoms, and exhibited significant yield decline. Application of biopesticides checked the severity of the diseases and the resulting yield declines. Application of Biowilt-X decreased the wilt incidence by 60% and promoted the yield of chickpea (46%) grown in F. oxysporum f. sp. ciceri infested plots. The biopesticides Bionem-X and Biocure-X were found effective against root-knot disease and suppressed the galling by 20 and 12% and promoted the yield of infected chickpea plants by 28 and 34% in comparison to the control. Application of Biocure-X was found highly effective against the fungus-nematode wilt disease complex; its seed treatment substantially controlled the wilt and root-knot, and increased the yield of concomitantly infected chickpea by 49°C. Biocure-X was found more effective in increasing the nodulation as compared to other treatments. Effect of carbendazim and nemacur was significant (P Less Than 0.05) in checking the wilt, root knot and disease complex but were not as effective as biopesticides. The present study has demonstrated that biological management of wilt, root-knot and disease complex can be successfully achieved with the application of the developed biopesticides.

Legume Research An International Journal. The Journal is an official publication of Agricultural Research Communication Centre. It is designed to bring out the original research articles on genetics, breeding, physiology, bacterial avtivity, production, quality, biochemistry and seeds of legumes crops. The objective of the journal is to serve as a forum for scientific community to publish their research findings on legumes ans to provide basis for new research. Journal is being scanned in the important indexing and abstracting services.
