Can cover crops reduce leafhopper abundance in vineyards?
economi(about 15%) ) was rarely mechacally important and the nisms leading to reduction were not clear. For example, l , there numwere few differences f in the berr off leafhopperr predators or parasitoids on i the vines in cover cropped versus no coverr sigplots. However, r, there were differnificant between-treatment ences in vine growth. Plots with seasonwide maintenance off a cove...
متن کاملCan Flowering Greencover Crops Promote Biological Control in German Vineyards?
Greencover crops are widely recommended to provide predators and parasitoids with floral resources for improved pest control. We studied parasitism and predation of European grapevine moth (Lobesia botrana) eggs and pupae as well as predatory mite abundances in an experimental vineyard with either one or two sowings of greencover crops compared to spontaneous vegetation. The co-occurrence betwe...

متن کاملDiversity and Abundance of Leafhoppers in Canadian Vineyards
Leafhoppers (Hemiptera: Cicadellidae) are pests of many temperate crops, including grapevines (Vitis species). Uncontrolled populations can induce direct and indirect damage to crops due to feeding that results in significant yield losses and increased mortality in infected vineyards due to virus, bacteria, or phytoplasmas vectored by leafhoppers. The main objective of this work was to determin...
متن کاملSummer cover crops reduce atrazine leaching to shallow groundwater in southern Florida.
At Florida's southeastern tip, sweet corn (Zea Mays) is grown commercially during winter months. Most fields are treated with atrazine (6-chloro-N-ethyl-N'-[1-methylethyl]-1,3,5-triazine-2,4-diamine). Hydrogeologic conditions indicate a potential for shallow groundwater contamination. This was investigated by measuring the parent compound and three degradates--DEA (6-chloro-N-[1-methylethyl]-1,...
