Biocontrol of Sclerotinia lettuce drop by Coniothyrium minitans and Trichoderma hamatum
Biological Control, 2006Abstract Fungal isolates, with known activity against Sclerotinia spp. in laboratory assays, were tested for their ability to control Sclerotinia minor in four field experiments (1998–2000). In the first experiment, eight fungal isolates (Trichoderma hamatum LU595, LU593, LU592, Trichoderma virens LU555 and LU556, Coniothyrium minitans LU112 ...

Lettuce drop caused by inoculum ofsclerotinia sclerotiorum blown-in from a distance
Phytoparasitica, 1987In seven fields free of local viable sclerotia, the part played bySclerotinia sclerotiorum ascospores transported from outside these fields in the incidence of lettuce drop was determined on plants not sprayed against the fungus. Ascospores were continuously deposited on the crop during the growth period and were found in low numbers in five of the ...

GENETIC ANALYSIS OF RESISTANCE TO LETTUCE DROP CAUSED BY SCLEROTINIA MINOR
Acta Horticulturae, 2004Despite extensive germplasm screening, no lettuce accessions have been identified as possessing immunity to infection by Sclerotinia species. As previously reported, several genotypes have consistently shown a significant reduction in disease incidence compared with susceptible varieties following inoculation with S. minor.

Biological Control, 2010
Abstract Field experiments were conducted over 2 years in Yuma County, Arizona and Imperial County, California, to evaluate if increased application rates of a commercial formulation of Coniothyrium minitans (Contans) were effective against lettuce drop caused by Sclerotinia minor. The efficacy of C. minitans at varied application rates were compared

Solarization and fungicides for the control of drop, bottom rot and weeds in lettuce
Crop Protection, 2006Abstract Soil solarization was applied for 60 days during the summer in lettuce fields in Mogi das Cruzes (latitude 22°31′S, longitude 48°11′W), southeastern Brazil, from December to January, 1998/99 and 1999/2000, after which two consecutive lettuce crops were grown in each cropping season.

Economical Biological Control of Sclerotinia Lettuce Drop bySporidesmium sclerotivorum
Phytopathology, 1990In a field trial, lettuce plants infected with Sclerotinia minor were treated with a preparation of Sporidesmium sclerotivorum at rates of 0, 0.2, 2, or 20 kg/ha of Sporidesmium product in May 1987. From the fall of 1987 to the fall of 1989, five successive lettuce crops were grown in this field with no additional application of the biocontrol agent ...

Biological control of Botrytis gray mould and Sclerotinia drop in lettuce.
Communications in agricultural and applied biological sciences, 2006Research was carried out to evaluate the effectiveness of the biological control of two most important fungal diseases of lettuce (Lactuca sativa L.): 1) Botrytis Gray Mould caused by Botrytis cinerea Pers. ex Fr.; 2) Sclerotinia Drop caused by two pathogenic fungi, Sclerotinia sclerotiorum (Lib.) De Bary and/or Sclerotinia minorJagger.
