The bioherbicidal fungus, Colletotrichum truncatum (Schwein.) Andrus & Moore, was tested at different inoculum concentrations alone and in combination with, prior to or following treatment with different rates of glyphosate (N-[phosphonomethyl]glycine) (Roundup Ultra) for the control of hemp sesbania (Sesbania exaltata [Raf.] Rydb. ex A.W. Hill) in Roundup Ready soybean field plots. Colletotric...
Target-site and non-target-site herbicide tolerance are caused by the prevention of herbicide binding to the target enzyme and the reduction to a nonlethal dose of herbicide reaching the target enzyme, respectively. There is little information on the molecular mechanisms involved in non-target-site herbicide tolerance, although it poses the greater threat in the evolution of herbicide-resistant...
Glyphosate-based herbicides are the number one pesticide in the United States and are used commonly around the world. Understanding the affects of glyphosate-based herbicides on non-target wildlife, for example amphibians, is critical for evaluation of regulations pertaining to the use of such herbicides. Additionally, it is important to understand how variation in biotic and abiotic environmen...
The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...
introduction: water is the main carrier of herbicides (hc) that its quality plays an important role in herbicide performance hard water has a high concentration of ca++ and mg++ and reviews have shown that calcium, manganese and zinc are the main factors reducing the effectiveness of weak acid herbicides. weak acid herbicides such as glyphosate, paraquat, clethodim and 2, 4 d are compounds that...
the susceptibility to terbacil of six randomly selected strawberry cultivars (‘aromas’, ‘chambly’, ‘harmonie’, ‘kent’, ‘la clé des champs’ and ‘seascape’) was analysed using chlorophyll florescence (cf) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. terbacil was applied at one of five rates...
Camera-guided narrow (15 cm)-row, inter-row cultivation, with or without the Einböck rotary weeder, reduced weed growth but had lower yield than herbicide-treated dry beans. In wide rows (60 cm), camera guidance improved finger weeder performance and mechanically weeded bean yields were similar to herbicide treatment.
