“…Herbicide drift onto agricultural field boundaries and offsite plant damage are well documented (Marrs et al 1989;Boutin and Baril 1997). Consequently, many of the remaining natural hedgerows may have been degraded due to herbicide, but also by fertiliser drift (Rew et al 1992;Boutin and Jobin 1998) and other management practices, e.g., selective wood removal by farmers, ploughing too close to hedgerow edges.…”

Choinière, L. 2001. Comparing weed composition in natural and planted hedgerows and in herbaceous field margins adjacent to crop fields. Can. J. Plant Sci. 81: 313-324. Hedgerows and field margins are common features of the agricultural landscape in southern Québec. In the last decade, hedgerow establishment has been encouraged primarily for the prevention of soil erosion, though many farmers view them as reservoirs of invasive weeds and pests. In this study, we compared weed assemblages of several hedgerow types and herbaceous field margins. Ranking that takes into consideration weed abundance was clearly demonstrated: planted hedgerows > herbaceous field margins > natural woody hedgerows. The latter harboured many perennial plant species of less weedy propensity than planted hedgerows, which accommodated a larger number of weedy species. In planted hedgerows close to 50% of plants were weeds, even in their central position, although planted and natural hedgerows sheltered similar weed composition in their central parts. Likewise, most species inventoried in adjacent fields were weeds. Weeds characterising the central position of hedgerows/field margins were often species of wet habitats (Lythrum salicaria L., Equisetum arvense L., Cicuta maculata L.). Management practices of hedgerows and perhaps of crop fields adjacent to hedgerows may be mostly responsible for the abundance of weeds in hedgerows and field margins. Les haies brise-vent et les bordures herbacées font partie intégrante du paysage agricole du Québec méridional. L'implantation de haies a récemment été encouragée pour réduire les problèmes liés à l'érosion éolienne mais plusieurs producteurs agricoles voient toujours les haies comme des réservoirs d'espèces nuisibles. Nous avons étudié la composition et la distribution des espèces végétales nuisibles aux cultures dans différents types de haies et un patron clair de l'abondance de ces espèces a été trouvé: haies plantées > bordures herbacées > haies naturelles boisées. Ce dernier type de haie abritait plus d'espèces vivaces non nuisibles aux cultures que les haies plantées lesquelles abritaient surtout des espèces nuisibles. Ainsi, plus de 50% des espèces retrouvées dans les haies plantées étaient des espèces nuisibles, même celles présentes au centre des haies, malgré le fait que la composition spécifique des espèces nuisibles retrouvées au centre des haies naturelles et plantées était similaire. La plupart des espèces inventoriées dans les champs adjacents étaient aussi des espèces nuisibles. Plusieurs des espèces nuisibles retrouvées au centre des haies et des bordures herbacées sont typiques des milieux humides (Lythrum salicaria L., Equisetum arvense L., Cicuta maculata L.). La présence d'espèces nuisibles dans les haies brise-vent et dans les bordures herbacées semble être une conséquence de l'aménagement des haies en soi et possiblement des pratiques agricoles ayant cours dans les champs cultivés adjacents.

“…Habitats adjacent to cultivated fields, although not targeted during application, may be affected by pesticides due to spray drift. It has been estimated that under certain conditions, more than 10% of herbicides can drift from the point of application to non-target habitats (Maybank et al 1978;Marrs et al 1989) and that plants that occur in these habitats may suffer from herbicide spray drift (Conacher and Conacher 1986;Marrs et al 1989). Weed communities can also be altered by pesticide use (Freemark and Boutin 1995), but little is known about their distribution in habitats abutting areas to which pesticides have been applied.…”

“…The greatest quantities of pesticides are used in the regions south of Montreal, the largest area of grain and vegetable crops production. Several studies have shown that agricultural pesticides can have adverse effects on surrounding animal and plant life (Potts 1985;Marrs et al 1989). Insecticides, which are generally the most acutely toxic pesticides to faunal wildlife (Hudson et al 1984), are extensively used in the production of vegetable and fruit crops.…”

Jobin, B., Boutin, C. and DesGranges, J.-L. 1997. Effects of agricultural practices on the flora of hedgerows and woodland edges in southern Quebec. Can. J. Plant Sci. 77: 293-299. The structure and distribution of herbaceous species were examined in cultivated fields and in adjacent habitats in light of herbicide use and tillage. The diversity and vegetation cover of the herbaceous layer of hedgerows and woodland edges were lower on sites at which herbicides had been sprayed in recent years, probably due to herbicide drift during application on adjacent fields. Herbicide use and tillage had an impact on the species composition of the cultivated fields: there was a higher proportion of annual and introduced species in cultivated fields subjected to herbicide use and tillage than in fields that were not regularly treated or tilled. The species that were found only in non-crop habitats were primarily native and perennials, few of which were weed species, whereas a high proportion of the species found only in cultivated fields were annual and introduced species, several of which were considered weeds.

“…Herbicide-resistant crops have enabled more simplifi ed herbicide programs (Young, 2006) that increase selection pressure for HR weeds (VanGessel, 2001). Concerns regarding the negative impacts of HR weeds (Peterson, 1999;Sosnoskie and Culpepper, 2014), herbicide pollution (Smith et al, 1996;Hill et al, 2002;Gilliom, 2007), and non-target toxicity of herbicides (Marrs et al, 1989;Hayes et al, 2002), provide impetus for research that explores weed management methods less reliant on herbicides.…”

Green Manure Comparison between Winter Wheat and Corn: Weeds, Yields, and Economics

Red clover (Trifolium pratense L.) and hairy vetch (Vicia villosa Roth) are leguminous crops ("green manure" hereaft er), widely studied for their N 2 -fi xing contributions to cropping systems. Under certain circumstances they can provide weed control in cash crops. Th is study compared weed control, crop yields, herbicide use, and economic performance of these green manures in a no-till winter cereal-green manure-corn (Zea mays L.) silage cropping sequence in central Pennsylvania. Red clover was interseeded into winter wheat (Triticum aestivum L.) or rye (Secale cereale L.), while hairy vetch and triticale (X Triticosecale) were planted aft er winter cereal harvest. Compared to hairy vetch, red clover provided continuous soil cover between the winter cereal and corn and two herbicide applications could not be applied (one in wheat and one prior to seeding hairy vetch) to the red clover, reducing herbicide active ingredient use by 28%. Weed infestation in wheat and corn did not differ between green manure systems, but corn yield following red clover averaged 3320 kg ha -1 more, and 2012 wheat yield was 180 kg ha -1 greater in the red clover sequence. Corn aft er hairy vetch-triticale had lower corn plant population in 2012-2013. Yield diff erences in corn in 2012 probably resulted from population diff erences. Primarily because of red clover forage value, the red clover system resulted in greater net returns to management by US$1360 ha -1 , and even without the forage harvest, the red clover system would have been more profi core ideas• As a green manure, red clover provided multiple benefi ts over hairy vetch and triticale.• Red clover underseeded in winter grain, produced continuous cover, forage, and higher corn yield.• Compared to hairy vetch and triticale, red clover controlled weeds with less herbicide.• Red clover was more profi table than hairy vetch.
