Does agroecosystem management mitigate historic climate impacts on dryland winter wheat yields?
Abstract Global studies that quantify climate effects on crop yields using top‐down spatial frameworks are invaluable for assessing generalized effects on world food supplies, yet do not contain the resolution necessary to identify local mediating effects of management. Our objectives were to identify (a) what climate factors have historically affected

Herbicide Resistance Management in Florida Tomato Production
Herbicide resistance was historically not a significant issue in most horticultural crops because few herbicides were applied. Close proximity of agronomic crops and the loss of methyl bromide has led to a gradual increase in herbicide inputs and the ...

Site-specific weed management in corn using UAS imagery analysis and computer vision techniques [PDF]
Currently, weed control in commercial corn production is performed without considering weed distribution information in the field. This kind of weed management practice leads to excessive amounts of chemical herbicides being applied in a given field.

Molecular Mechanisms of Herbicide Resistance [PDF]
Resistance to herbicides occurs in weeds as the result of evolutionary adaptation (Jasieniuk et al. 1996). Basically, two types of mechanisms are involved in resistance (Beckie and Tardif 2012; Délye 2013). Target-site resistance (TSR) is caused by changes in the tridimensional structure of the herbicide target protein that decrease herbicide binding ...

Weed Resistance to Herbicides [PDF]
Weed resistance is more and more becoming a problem under intense agricultural conditions. Recognizing this problem has high practical importance not only for detection of resistant weeds but also for application of measures for prevention of development of resistance or control of already resistant weed populations.

Agricultural Weed Assessment Calculator: An Australian Evaluation
Weed risk assessment systems are used to estimate the potential weediness or invasiveness of introduced species in non-agricultural habitats. However, an equivalent system has not been developed for weed species that occur in agronomic cropland ...

Managing the evolution of herbicide resistance [PDF]
AbstractBACKGROUNDUnderstanding and managing the evolutionary responses of pests and pathogens to control efforts is essential to human health and survival. Herbicide‐resistant (HR) weeds undermine agricultural sustainability, productivity and profitability, yet the epidemiology of resistance evolution – particularly at landscape scales – is poorly ...

Current Status of Herbicide Resistance in the Iberian Peninsula: Future Trends and Challenges
The evolution of herbicide resistance in weeds has emerged as one of the most serious threats to sustainable food production systems, which necessitates the evaluation of herbicides to determine their efficacy.

Novel α-Tubulin Mutations Conferring Resistance to Dinitroaniline Herbicides in Lolium rigidum
The dinitroaniline herbicides (particularly trifluralin) have been globally used in many crops for selective grass weed control. Consequently, trifluralin resistance has been documented in several important crop weed species and has recently reached a ...

Herbicide Resistance Management: Recent Developments and Trends
This review covers recent developments and trends in herbicide-resistant (HR) weed management in agronomic field crops. In countries where input-intensive agriculture is practiced, these developments and trends over the past decade include renewed ...
