Modifications in the structure of grasslands have been responsible for decline several avian species due to a reduced quality available habitat. Currently, applications herbicide glyphosate introduced promote winter forage production Flooding Pampas Argentina. Rotational grazing has another technique used production. Here, we evaluated different managements cattle systems on richness, compositi...

Abstract Italian ryegrass [ Lolium perenne L. spp. multiflorum (Lam.) Husnot] is one of the most troublesome weeds worldwide. also a grass seed crop cultivated on 50,000 ha in Oregon, where both diploid and tetraploid cultivars are grown. For this work, we will refer to species as multiflorum, since common names annual same species. A survey was conducted understand distribution frequency its s...

The allelopathic effects of different parts of the plant Xanthium italicum Moretti were evaluated by conducting bioassays against two dicot plants, amaranth (Amaranthus mangostanus L.) and lettuce (Lectuca sativa L.), and two monocot plants, wheat (Triticum aestivum Linn) and ryegrass (Lolium multiforum). Leaf and fruit extract possessed the strongest biological activity, killing all seeds of f...

The rice stink bug, Oebalus pugnax (F.), is a graminaceous feeder, and the most injurious insect pest of heading rice, Oryza sativa L., in the United States. Rice growers are aware of the economic importance of host grasses in O. pugnax abundance. However, the need for increased knowledge of host sequence relative to O. pugnax abundance is vital. Densities of O. pugnax on 15 graminaceous hosts ...

Aquatic and terrestrial plants and microorganisms were screened to test their ability to remove the herbicide, atrazine, from the environment. Plants included hornwort (Ceratophyllum demersum), switchgrass (Panicum virgatum), reed canarygrass (Phalarius arundinacea), annual ryegrass (Lolium multiflorum), and two varieties ofperennial ryegrass (Lolium perenne). Microorganisms studied included a ...

The introduction of harvest weed seed control (HWSC) techniques and associated machinery has enabled the routine use an alternative technology at a novel timing in global grain cropping fields. Driven by significant threat widespread populations annual ryegrass (Lolium rigidum) with multiple-herbicide resistance, 1990s Australian growers researchers developed to target, harvest, production othe...

Low-external-input (LEI) cropping systems that include forage legumes and small grains in addition to corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] can achieve similar or higher crop productivity and economic return than conventional corn-soybean rotations. We hypothesized that this rotation effect occurs regardless of the crop genotype planted and the herbicide and cultivation regime...

Abstract Rigid ryegrass ( Lolium rigidum Gaudin) is the most problematic weed in Australia, with evolved resistance to multiple herbicide sites of action. Selection pressure by cinmethylin (Group 30, a fatty-acid thioesterase inhibitor) has been limited, because few populations have exposed since its introduction 2019. In this study, we examined sensitivity L. new herbicide. From screening almo...

The compositions of the germinable weed seedbank and aboveground weed communities in a long-term tillage and rotation study were characterized 4, 5, and 6 yr (2002 to 2004) after the adoption of glyphosate-tolerant corn and soybean. Averaged across rotation, mean germinable weed seed density and diversity were greatest in the no-tillage treatment as compared to the minimumand conventional-tilla...

mix cropping of alfalfa (medicago sativa) and annual ryegrass (lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. in this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...
