Challenges And Opportunities For Weed Control In Nebraska Popcorn, Ethann R. Barnes Oct 2019

Challenges And Opportunities For Weed Control In Nebraska Popcorn, Ethann R. Barnes

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Weed control in popcorn is challenging with limited herbicide options and popcorn’s perceived sensitivity to herbicides. Understanding the impact of weeds maximizes yield and profit. New herbicide-resistant crops increase chances of drift or misapplication into popcorn, which doesn’t have herbicide-resistant traits. Herbicides that are labeled in popcorn are often only conditionally labeled with reduce rates, warnings, or limited popcorn types. Dent-sterility in popcorn is contingent on the Ga1 gene (Ga1-s), but this system is at risk from Ga1-m field corn introduced from Mexico because it overcomes dent-sterility. This risk is under-assessed as Ga1-m carriers are undocumented and Mexican ...


Mulch And Groundcover Effects On Soil Temperature And Moisture, Surface Reflectance, Grapevine Water Potential, And Vineyard Weed Management, Christina M. Bavougian, Paul E. Read Jan 2018

Mulch And Groundcover Effects On Soil Temperature And Moisture, Surface Reflectance, Grapevine Water Potential, And Vineyard Weed Management, Christina M. Bavougian, Paul E. Read

Agronomy & Horticulture -- Faculty Publications

The objectives of this research were to identify alternatives to glyphosate for intra- row (under-trellis) vineyard floor management and to evaluate the potential for intra- row and inter-row (alleyway) groundcovers to reduce vegetative vigor of `Marquette' grapevines (Vitis spp.) in a southeast Nebraska vineyard. The experiment was a randomized factorial design with five intra-row treatments (crushed glass mulch [CG], distillers' grain mulch [DG], creeping red fescue [CRF], non-sprayed control [NSC], and glyphosate [GLY]) and three inter-row treatments (creeping red fescue [CRF], Kentucky bluegrass [KB], and resident vegetation [RV]). Treatments were established in 2010-2011 and measurements were conducted during 2012 and ...


Glyphosate-Resistant Weed Control And Soybean Injury In Response To Different Ppo-Inhibiting Herbicides, Jatinder S. Aulakh, P. S. Chahal, Amit J. Jhala Jan 2016

Glyphosate-Resistant Weed Control And Soybean Injury In Response To Different Ppo-Inhibiting Herbicides, Jatinder S. Aulakh, P. S. Chahal, Amit J. Jhala

Agronomy & Horticulture -- Faculty Publications

In Nebraska, 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) as well as acetolactate synthase (ALS)-inhibitor-resistant weeds occur in many soybean fields where herbicides from these modes-of-action have been frequently used in the past. Currently, the protoporphyrinogen oxidase (PPO)-inhibitors are the only effective herbicides for POST control of both glyphosate- and ALS-inhibitor-resistant weeds in soybean. Greenhouse experiments were conducted in 2014 to evaluate the efficacy of PPO-inhibitors applied POST for the control of three glyphosate-resistant (GR) weeds and potential for soybean injury, when applied at two growth stages. All herbicide treatments controlled 10- and 20-cm tall GR common waterhemp ≥ 95% at 21 ...

Clearwing Moths Are Key To Dock Control, Kingsley Fisher Jan 1992

Clearwing Moths Are Key To Dock Control, Kingsley Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Two clearwing moths imported from Morocco and France could be the key to controlling dock (Rumex pulcher) - one of the worst weeds of high rainfall pastures in southern Australia


The Potential For Skeleton Weed, John Dodd, F. D. Panetta Jan 1987

The Potential For Skeleton Weed, John Dodd, F. D. Panetta

Journal of the Department of Agriculture, Western Australia, Series 4

Since its introduction into Australia during the 900s skeleton weed has become one of the most economically significant weeds. Its presence in cereal crops in south-eastern Australia has caused suvere yield reductions and harvesting problems.

Skeleton weed was first found on a Western Australian farm in 963. Since then it has been the subject of an intensive eradication campaign organised by the Agricultural Protection Board and funded by an annual levy on wheat growers. Such campaigns, which rely mainly on volunteer searchers, do not exist in eastern Australia because the weed is so widespread it would be impossible to eradicate ...


Beating The Blackberry, J H. Moore, E. B. Hoskins Jan 1985

Beating The Blackberry, J H. Moore, E. B. Hoskins

Journal of the Department of Agriculture, Western Australia, Series 4

The blackberry is an aggressive, strongly-growing plant that has spread throughout parts of the south-west of Western Australia.

Although most blackberry infestations on agricultural land have been dramatically reduced since compulsory control measures were introduced 30 years ago, about 3,600 hectares are still infested today.

Recent research has shown that three new herbicides are highly effective against blackberry, and much safer to use than the older ones.

Effective biological control of blackberry may also be possible.

Docks In Western Australia, J M. Allen Jan 1975

Docks In Western Australia, J M. Allen

Journal of the Department of Agriculture, Western Australia, Series 4

A survey carried out by the Department of Agriculture has shown that docks are the most serious weed of the higher rainfall areas of Western Australia. They are estimated to cost farmers $400 000 annually in lost production. One of the main reasons why they are important weeds is that they regenerate rapidly from tubers and compete with desirable annual pasture species. Also the upright dock flowering stems are woody and unpalatable. Individual plants become intertwined and deter stock from grazing summer pastures.

Results from the survey of the dock problem are given in this article. The findings show that ...

The Control Of Annual (Wimmera) Ryegrass In Cereal Crops, Geoffrey A. Pearce, B. J. Quinlivan Jan 1971

The Control Of Annual (Wimmera) Ryegrass In Cereal Crops, Geoffrey A. Pearce, B. J. Quinlivan

Journal of the Department of Agriculture, Western Australia, Series 4

The annual ryegrasses are valuable pasture plants in Western Australia, yet have become one of the major weed problems in cereal crops.

The key to cultural control of annual ryegrasses in cereal crops is an understanding of the factors which govern germination of the seed.

Covering the seed with soil keeps out light and provides a more stable moisture supply, bringing about a faster rate of germination. This is the basis of control programmes recommended in this article.

Recommendations for chemical control are also included.


The Control Of Weeds In Linseed And Rape, Geoffrey A. Pearce Jan 1971

The Control Of Weeds In Linseed And Rape, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

Like all crops linseed and rapeseed can suffer from weed competition.

Linseed is highly susceptible to weed competition, while rape is susceptible to the chemicals used to kill broad-leaved weeds, so both crops pose special problems.

As in other broad-acre crops, cultural methods usually provide the best means of weed control.


Weed Control Research Pays Dividends, G R W Meadly Jan 1970

Weed Control Research Pays Dividends, G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.


Control Of Cape Tulip, Geoffrey A. Pearce Jan 1968

Control Of Wild Oats, J G. Paterson Jan 1967

Control Of Wild Oats, J G. Paterson

Journal of the Department of Agriculture, Western Australia, Series 4

WILD OATS are widespread throughout the world.

Their importance can be gauged from the fact that in the wheat growing areas of Canada and the U.S.A. some 60 million acres are infested.

Two chemicals are now available for the control of wild oats in wheat. This article compares their relative merits and gives recommendations for their use.


The Control Of Doublegee, Geoffrey A. Pearce Jan 1967

The Control Of Doublegee, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

FOUR years ago no practical recommendations could be made for the control of doublegee.

With money provided by the State Wheat Research Fund, research has been undertaken into the control of this weed, and there is now no reason why most farmers cannot bring doublegee under control.


Watch Out For Afghan Thistle, J G. Paterson Jan 1967

Watch Out For Afghan Thistle, J G. Paterson

Journal of the Department of Agriculture, Western Australia, Series 4

ALTHOUGH known throughout the cereal and sheep districts of Western Australia as Afghan thistle, this plant is not really a thistle at all.

It belongs to the large botanical family of the Solonaceae and is closely related to the garden vegetables tomato and potato.

Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.


Weeds Of Western Australia : Cape Tulip (Homeria Breyniana (L.) Lewis And H. Miniata Sweet), G R W Meadly Jan 1960

Weeds Of Western Australia : Cape Tulip (Homeria Breyniana (L.) Lewis And H. Miniata Sweet), G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

SOUTH Africa has provided us with a number of undesirable weeds including doublegee, Berkheya thistle, Guildford grass and stinking roger, but outstanding among the weed introductions from that country are two species of Homeria known as Cape Tulip.

The salmon-coloured flowers and long grass-like leaves are known to farmers in many localities extending from Geraldton to Albany and as far east as Bruce Rock and Merredin. Beyond the metropolitan area the largest infestations occur in the Northam, York, Beverley and Williams districts where thousands of acres of good land are affected.


Soursob (Oxalis Pes-Caprae L.), G R W Meadly Jan 1960

Soursob (Oxalis Pes-Caprae L.), G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

DURING winter and spring, the yellow colouration of paddocks is not always due to the flowers of the widely distributed Capeweed.

In some districts, particularly in the Avon Valley, the yellow-flowered soursob (Oxalis pes-caprae L.), has become firmly established.

The genus Oxalis contains 800 or more different species, the two main natural centres of distribution being South Africa and tropical and extra-tropical South America.
