Weed Control for Tall Fescue Seed Production and Stand Duration without Burning
grass (Mueller-Warrant and Brewster, 1986), common occurrences in grass seed fields. Seed laws and market Effective weed control was a major concern of Oregon grass seed expectations define allowable limits for weed seed congrowers during their recent transition from open-field burning to mechanical methods of managing post-harvest residues. This 4-yr herbitamination, but production efficiency ...
متن کاملTall fescue seed extraction and partial purification of ergot alkaloids
Many substances in the tall fescue/endophyte association (Schedonorus arundinaceus/Epichloë coenophiala) have biological activity. Of these compounds only the ergot alkaloids are known to have significant mammalian toxicity and the predominant ergot alkaloids are ergovaline and ergovalinine. Because synthetically produced ergovaline is difficult to obtain, we developed a seed extraction and par...
متن کاملChaparral Herbicide Application for Suppression of Seedhead Emergence in Tall Fescue Pastures and Possible Alleviation of Fescue Toxicosis
Chaparral herbicide has shown in small-plot experiments to suppress seed head emergence in tall fescue. A two-yr grazing experiment is being conducted with steers grazed on endophyte-infected tall fescue pastures that are either treated or untreated with Chaparral herbicide. The objective of the experiment is to determine if suppression of seed head emergence and maturity can increase average d...
متن کاملControl of Herbicide-resistant Volunteer Corn in Herbicide-resistant Soybean
Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...
متن کاملTall Fescue Toxicosis
widely used forage crop. It is insect and nematode resistant, tolerates poor soil and climatic conditions well and has a long growing season. Unfortunately, tall fescue also has a downside. Most tall fescue in the state is infected with a fungal endophyte, Neotyphodium coenophialum (formerly called Acremonium coenophialum) that is toxic to animals. Tall fescue was brought to this country from E...
