Long-Term Effect of Biological Soil Disinfestation on Verticillium Wilt

Plant Disease
Jan-Kees C GoudAriena H C van Bruggen

Abstract

Biological soil disinfestation (BSD), involving incorporation of grass combined with plastic mulching, eliminates many soilborne pests and diseases through the creation of anaerobic conditions. BSD was compared at two locations with a nontreated control, Italian ryegrass amendment alone, and plastic mulch alone. After the soil treatments, plots were cropped with Acer platanoides and Catalpa bignonioides and grown for 4 years. Relative to the control, soil inoculum levels of Verticillium dahliae were reduced by 85% after BSD and did not increase for 4 years. Populations of Pratylenchus fallax, known for their interaction with V. dahliae, in the soil and in roots were reduced by 95 to 99%. The incidence of infection by V. dahliae was reduced by 80 to 90%. Verticillium wilt severity was significantly reduced in A. platanoides in all 4 years at one location and in the first 2 years at the other location, and significantly fewer plants died at one location. Shoot length and trunk width were larger after BSD compared with the control at one location. Market value of the crop in BSD plots was up to € 140,000 ha-1 higher for A. platanoides and up to € 190,000 ha-1 higher for C. bignonioides than in the untreated control. BSD is an effe...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
