“…Fire blight, also known as leaf blight is a major threat to lily production worldwide. The disease poses a major economic threat and has been recorded in Argentina, China, Korea, Italy, Japan, Netherlands, Taiwan, United Kingdom, and the United States (Bastiaansen et al 1997;Chiou and Wu 2001;Doss et al 1988;Furukawa et al 2005;Hwang 2001;Mansfield and Hutson 1980;Migheli et al 1990). During the growing season, fire blight may affect numerous lily species such as Lilium candidum, Lilium longiflorum, Lilium auratum, and Lilium speciosum (Bastiaansen et al 1997;Doss et al 1988;Fang Hsieh et al 2001;Furukawa et al 2005).…”

“…The necrotic lesions develop and expand quickly under favourable environmental conditions (Chiou and Wu 2001;Hwang 2001;van Baarlen et al 2004). Control measures using fungicides for B. elliptica are common practice worldwide, however, it has been reported that B. elliptica acquires resistance to several fungicides including benzimidazoles, dicarboximides, diethofencarb, and two sterol biosynthesis inhibitors (Chastagner and Riley 1990;Migheli et al 1990).…”

Mating type and sexual fruiting body of Botrytis elliptica, the causal agent of fire blight in lily

Botrytis elliptica is a necrotrophic pathogen that specifically infects Lilium species. Previous records show that B. elliptica collected in the field can successfully develop apothecia in vitro, however, there are no formal descriptions of apothecia of B. elliptica. The aim of this study was to analyse the sequence of the mating type loci of B. elliptica and produce apothecia in the laboratory in order to describe their morphology. The sequences of both MAT alleles (MAT1-1 or MAT1-2) of B. elliptica were determined and compared to the sister taxa, Botrytis cinerea and Sclerotinia sclerotiorum. Two strains of each mating type were used in crosses under controlled conditions to produce apothecia. Primordium rupture from sclerotial tissue occurred 74 days after fertilization and a mature apothecium formed within 1 month after rupture. The apothecia are 7 to 12 mm in height with a disk of 3 to 4 mm in diameter and 0.5 to 1 mm in thickness. The apothecial disk is usually umbilicate, depressed to funnel and rounded in shape. The number of apothecia growing on a sclerotium was one to nine. Asci are long, cylindrical with a size of 208× 14 μm, thin walled and bearing eight ascospores. Ascospores are hyaline in colour, ellipsoidal with rounded ends, usually 18 to 24 μm in length and 6 to 10 μm in width (mean 19.5×8 μm). Ascospores were infectious on lily leaves.

“…However, several benzimidazolresistant fungi strains of Penicillium spp., Botrytis elliptica and Fusarium oxysporum have been already isolated on many bulb ornamental plants like tulips (Tulipa gesneriana L.), lilies (Lilium sp.) and gladiolus (Gladiolus communis L.) (Migheli et al, 1990;Bus et al, 1991;Chung et al, 2009). To overcome this problem and reduce the pesticide use, alternative methods based on the use of organic amendments for the biological control of soilborne plant pathogenic fungi has been reported (Hoitink et al, 1997;Abawi & Widmer, 2000).…”

The effect of olive mill wastewater (OMW) on growth of tulip plants infected by common diseases as well as on their new bulbs production is analyzed in this work. Filtered and sterilized OMW was tested as growth inhibitor of Botrytis tulipae, Fusarium oxysporum, Aspergillus niger and Penicillium spp. mycelium. The effect of filtered OMW on uninfected tulip bulbs was also tested as well as on the growth of bulbs infected with the fungus B. tulipae and A. niger in vivo. The mycelium length, severity of scab-like lesions, plant height (PH), fresh mass (FM) and dry mass (DM) of plants and production of new bulbs were recorded. Only the filtered OMW inhibited the in vitro mycelium growth of all tested fungi. However filtered OMW caused infections when it sprayed on uninfected bulbs, malformations on 30% of the plants grown from these bulbs and decrease PH, FM and DM as well as new bulbs production at 75%, 72.4%, 79.1% and 50% respectively. The treatment of B. tulipae infected bulbs with filtered OMW reduced further the PH, FM, DM and the production of new bulbs in 92.1%, 81.4%, 78.7% and 97% respectively. In contrast the treatment of infected bulbs by B. tulipae + A. niger with filtered OMW did not affect PH, FM and the number of new bulbs produced and significantly improved plants DM and the mass of new bulbs.

“…Fungicides have been frequently used to control the disease, but their use has several drawbacks: for example, within a very short time Botrytis spp. have developed resistance to specific fungicides such as benzimidazoles, dicarboximides, diethofencarb and two sterol biosynthesis inhibitors (Chastagner and Riley, 1990; Migheli et al., 1990; Elad, 1992; Elad and Shtienberg, 1995). Therefore, biological control might be a practical alternative as it is often durable, economical, environmentally compatible and stable.…”

Of the 700 micro‐organisms isolated from lily plants and screened by dual and concomitant cultures, 10 isolates (B99, B111, B128, B131, B171, B190, B196, B203, B501 and BS) had antagonistic effects against Botrytiselliptica on three lily cultivars in greenhouse trials. Using the Biolog system, isolates B99 and B111 were identified as Burkholderia gladioli, and B128 and B190 as Bacillus amyloliquefaciens. In the field, B. gladioli B111, B. amyloliquefaciens B128, B190 or 100 p.p.m. flusilazole effectively controlled the occurrence of lily grey mould (significance, P=0.05).
