“…album and E. crus-galli and other species, mainly Polygonum ssp., Solanum nigrum L., Amaranthus retroflexus L., and Anthemis arvensis L. (Tański and Idziak, 2009;Kierzek et al, 2011). According to Dewey and Andersen (2004) knowledge about weed community structure is critical for planning effective weed management system. There were significant differences among treatments in herbicidal efficacy on presented weed species based on their biomass reduction (Table 2).…”

Due to the steadily increasing cost of weed control in corn (Zea mays L.) and possible negative impact of chemicals on environment the demand for less and more efficient herbicide use is rising. Field studies were carried out in 2010 and 2011 in the Middle-West Poland in order to assessment the effective weed control. Treatments included herbicides tembotrione and flufenacet + isoxaflutole at recommended (88.0 and 36.0 + 7.5 g ha -1 ) and reduced rates (44 and 22 g ha -1 ; 19.2 + 4.0 or 9.6 + 2.0 g ha -1 ) with addition of methylated seed oil (MSO) and ammonium nitrate (AMN) adjuvants. Tembotrione was applied once at the stage of 3-5 maize leaves and flufenacet + isoxaflutole once at pre-emergence of maize. Mixtures of these herbicides were applied sequentially post-emergence, at 16-20-d intervals, after successive weed emergence. Results indicate that herbicide applied at reduced rates with adjuvants provided satisfactory weed control in maize. Application of reduced rates of tembotrione (44 and 22 g ha -1) and especially mixture of tembotrione with flufenacet + isoxaflutole and MSO + AMN adjuvants applied twice provided similar grain yield of maize as from treatments where tembotrione or flufenacet + isoxaflutole herbicides were applied only once at recommended rates (9.5, 9.7, and 10.0 t ha -1 , respectively).

“…Ground surveys are still commonly used for most mapping projects despite intensive labor requirements, associated high economic costs, and incomplete coverage of the landscape [1][2]. Improved methods to accurately determine the current distribution of invaders are required to better assess their environmental impacts, formulate effective control strategies, and forecast potential spread.…”

Mapping Invasive Tamarisk (Tamarix): A Comparison of Single-Scene and Time-Series Analyses of Remotely Sensed Data

et al. 2009

Abstract:In this study, we tested the Maximum Entropy model (Maxent) for its application and performance in remotely sensing invasive Tamarix sp. Six Landsat 7 ETM+ satellite scenes and a suite of vegetation indices at different times of the growing season were selected for our study area along the Arkansas River in Colorado. Satellite scenes were selected for April, May, June, August, September, and October and tested in single-scene and time-series analyses. The best model was a time-series analysis fit with all spectral variables, which had an AUC = 0.96, overall accuracy = 0.90, and Kappa = 0.79. The top predictor variables were June tasselled cap wetness, September tasselled cap wetness, and October band 3. A second time-series analysis, where the variables that were highly correlated and demonstrated low predictive strengths were removed, was the second best model. The third best model was the October single-scene analysis. Our results may prove to be an effective approach for mapping Tamarix sp., which has been a challenge for resource managers. Of equal importance is the positive performance of the Maxent model in handling remotely sensed datasets.

“…Prioritizing species is usually necessary and should be based on ecological threat and the feasibility of management success, focusing on taxa that pose a high threat and/or are most feasible to manage (Hiebert et al 1993). For more detailed accounts of management strategies and invasive plant ecology, we recommend the following sources: Radosevich et al (2007), Kaufman et al (2007), Mooney et al (2005), Buckley (2008), Holt (2004), Dewey et al (2004), James et al (2010), andBooth et al (2010).…”

“…Having management plans in place prior to INS introduction greatly improves the ability of stewards to respond quickly and effectively. Regular surveys, inventories, and monitoring should be done to detect new introductions, assess the scale of infestations, and measure the success of management actions (Dewey et al 2004). Prevention measures should be put in place whenever possible.…”
