The bindweeds Calystegia sepium and Convolvulus arvensis are difficult to control chemically. Calystegia sepium is often a problem in maize or in vineyards, while C. arvensis is an important weed of cereals. The biological control of these weeds with insects or fungal pathogens has been investigated since 1970. More than 600 fungi collected in countries throughout Europe have been isolated in o...

Abstract Field studies were conducted in 2021 Kibler and Augusta, AR, to determine the effect of winter cover crops cultivar selection on weed suppression sweetpotato [ Ipomoea batatas (L.) Lam.] yield. The split-split-plot evaluated three [cereal rye ( Secale cereale L.) + crimson clover Trifolium incarnatum L.)], [winter wheat Triticum aestivum clover], fallow; weeding (with or without); four...

The organic industry continues to expand in the United States (U.S.), with 14,093 organic farms in 2014. The upper Midwestern U.S. has emerged as a hub for organic row crop production; however, the management of these organic row crop hectares heavily relies on tillage and cultivation for weed control. Faced with the soil quality challenges related to these practices, and cognizant of the benef...

Abstract Cover crops enhance the biodiversity of cropping systems and can support a variety useful ecosystem services, including weed suppression. In California orchards, cover are typically implemented as annual plants that replace resident vegetation in orchard alleyways during rainy winter season. Our research objective was to evaluate crop management factors competitive, weed-suppressing un...
