Severe violet root rot occurred in a field of membranous milk vetch in Bonghwa, Korea, in October 2010. Two fungal isolates from the diseased plants were identified as Helicobasidium mompa based on their morphological, cultural, and molecular characteristics. This is the first report that H. mompa causes violet root rot on membranous milk vetch in Korea.

The activity of cathepsin D inhibitor is markedly higher in common vetch seed coat than in embryo cotyledons. The occurrence of considerable amounts of the inhibitor in the seed coat of vetch was confirmed by the fluorescent microscopic technique, with the use of fluorescein-marked cathepsin D.

There are often negative side-effects associated with the traditional (silage) maize cropping system related to unprotected soil surface. Reducing disturbance could enhance sustainability. Yet, increased weed pressure and decreased nitrogen availability, particularly in organic agriculture, may limit implementation of alternative management methods. Therefore, a field experiment was conducted a...

Summary Root-knot nematode (RKN) is an important pathogen on vegetables; therefore, planting a non- or poor host cover crop following susceptible vegetable promising management option. This study builds upon previous studies and evaluates the variations in status of candidates for reducing reproduction RKN populations ( Meloidogyne incognita , M. arenaria javanica ) Georgia, USA, to shed light ...

Techniques based on terminated cover crops are proposed in organic agriculture instead of traditional inter-row tillage for weed control subsequent grain crops. We estimated the profitability and evaluated riskiness novel techniques compared to one. Two-year yield data from three on-farm trials corn one soybean northern Italy were combined with cost revenue calculate compare gross margin distri...
