Changes in populations of soilborne pathogens after rotational crops following potatoes

Impact of soil health management practices on soilborne pathogens, nematodes and root diseases of vegetable crops

Various cultural practices, including the use of cover and rotational crops, composts, tillage systems, and others have been promoted as management options for enhancing soil quality and health. All cultural practices are known to directly or indirectly affect populations of soilborne pathogens and the severity of their resultant root diseases. Soil biology is a major component and contributes ...

Host Growth Can Cause Invasive Spread of Crops by Soilborne Pathogens

Invasive soilborne plant pathogens cause substantial damage to crops and natural populations, but our understanding of how to prevent their epidemics or reduce their damage is limited. A key and experimentally-tested concept in the epidemiology of soilborne plant diseases is that of a threshold spacing between hosts below which epidemics (invasive spread) can occur. We extend this paradigm by e...

Reduced dosages of methyl bromide applied under gas-impermeable plastic "lms for controlling soilborne pathogens of vegetable crops

Four experimental trials were carried out at Albenga (Northern Italy) to evaluate the e!ectiveness of reduced dosages of methyl bromide (MB) applied under gas-impermeable "lms in controlling soilborne pathogens of vegetable crops. Forty and thirty g/m2 of MB applied under di!erent types of gas-impermeable "lms controlled Rhizoctonia solani on bean, lettuce and basil, Fusarium oxysporum f. sp. b...

Field Flooding for Controlling Soilborne Potato Pathogens in Western Washington

Weed Control with Cover Crops in Irrigated Potatoes

Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...
