Biological Control of Lettuce Drop (Sclerotinia minor Jagger) Using Antagonistic Bacillus Species
Applied MicrobiologySclerotinia minor (S. minor) Jagger is a phytopathogenic fungus that causes lettuce drop, a serious problem in lettuce (Lactuca sativa L.) production. The control of this pathogen is challenging because of the resistance of sclerotia, which can survive ...

Epidemiological Characterization of Lettuce Drop (Sclerotinia spp.) and Biophysical Features of the Host Identify Soft Stem as a Susceptibility Factor [PDF]
PhytoFrontiers, 2021 The soilborne fungus Sclerotinia minor was not known to produce sclerotia in the stems of infected and uncollapsed Lactuca standing intact until our observation in a greenhouse in 2017. We investigated lettuce–environment–S.

Drops join to make a stream: high‐throughput nanoscale cultivation to grasp the lettuce root microbiome [PDF]
Environmental Microbiology Reports, 2021 Summary Root endospheres house complex and diverse bacterial communities, of which many strains have not been cultivated yet by means of the currently available isolation techniques. The Prospector® (General Automation Lab Technologies, San Carlos, CA, USA), an automated and high‐throughput bacterial cultivation ...

Dynamics of Lettuce Drop Incidence and Sclerotinia minor Inoculum Under Varied Crop Rotations [PDF]
Plant Disease, 2006 Field experiments were conducted to determine the population dynamics of Sclerotinia minor and incidence of lettuce drop at two sites during 1995 to 1998. Rotation treatments at the Spence site, which had a low density of inoculum (<7 sclerotia per 100 cm3 of soil) that was distributed randomly, included: continuous lettuce (LLL), lettuce rotated ...

Evaluating Leaf Wettability and Salt Hygroscopicity as Drivers for Foliar Absorption
Plants, 2023 The objective of this study was to evaluate the rate of foliar absorption of magnesium (Mg) salts with different deliquescence and efflorescence relative humidity values (DRH and ERH, also known as point of deliquescence (POD) and point of efflorescence (

Comparative Analyses of Lettuce Drop Epidemics Caused by Sclerotinia minor and S. sclerotiorum [PDF]
Plant Disease, 2005 Temporal and spatial patterns of lettuce (Lactuca sativa) drop caused by Sclerotinia minor and S. sclerotiorum were determined in lettuce fields in the Salinas, Santa Maria, and San Joaquin Valleys in California during 1995 to 1998. Of the 25 commercial fields assessed, 14 had predominantly S. minor, 9 had predominantly S.

Persistent, symptomless, systemic, and seed-borne infection of lettuce by Botrytis cinerea [PDF]
, 2010 Experiments are presented which show that Botrytis cinerea, the cause of gray mould disease, is often present in symptomless lettuce plants as a systemic, endophytic, infection which may arise from seed.
