Field experiments were conducted to determine the effects of various densities of four fall-seeded small grain mulches and diphenamid (N,N-dimethyl-α-phenyl benzeneacetamide) on weed control, yield, and quality in no-till flue-cured tobacco (Nicotiana tabacumL. ‘McNair 944’). A greenhouse study investigated the effects of non-soil-incorporated mulch from the same small grains plus alfalfa (Medicago sativaL.) on various growth parameters of tobacco (‘Speight G-70’). None of the mulches used in the greenhouse study adversely affected growth of the tobacco. Mulch from rye (Secale cerealeL. ‘Abruzzi’) killed about 2 weeks before transplanting plus diphenamid provided better annual broadleaf weed control (85%) than wheat (Triticum aestivumL. ‘McNair’), barley (Hordeum vulgareL. ‘Keowee’), and no mulch. Oat (Avena sativaL. ‘Brooks’) mulch resulted in 80% broadleaf weed control. There were no differences in annual grass control (which was short lived) among mulches but control was lower in the no-mulch treatment. Rye mulch resulted in a 22% increase in the control of broadleaf weeds compared to no-mulch. Yield of the no-till tobacco did not differ among mulches and averaged 82% of that conventionally grown. The quality was not affected. The rye mulch did not affect the yield or quality of tobacco when compared to a nonmulch, noncultivated treatment. The 18% decrease in the no-till yield was apparently the result of the lack of tillage and increased weed interference and was not due to adverse effects from the rye.

A field experiment was conducted at the Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology -Udaipur during Kharif season 2015 and 2016 to test the efficacy of different herbicide and herbicide mixtures against weeds in soybean. Monocot weeds were predominant (57.68 %) in the experimental field compared to Broad leaved weeds (42.31 %). However, Echinochloa colona (40.55 %) and Corchorus olitorius (23.68%) were dominant in soybean at 30 DAS. Among different weed control treatments, post-emergence and tank mix combination of propaquizafop + imazethapyr (75+75 g ha-1) and imazethapyr + quizalofop-ethyl (75+60 g ha-1) at 21 DAS were most effective in respect of reducing weed density, weed biomass, nutrient removal by weed and improving yield attributes, yield and quality of soybean compared to other treatments. Highest seed yield (2271 kg ha-1), Haulm yield (3127 kg ha-1) of soybean and maximum net return ( 51550/ha) were also recorded with propaquizafop 75 g ha-1 + imazethapyr 75 g ha-1 followed by imazethapyr + quizalofop-ethyl (75+60 g ha-1). Further, they were also found responsible for highest uptake of N, P and K in soybean and lowest uptake of these plant nutrients by weeds.

ABSTRACT: Floriculture and landscaping sector has the same problems as other crops regarding weed management. Weeds affect the yield and quality of the harvested product, in which the visual aspect and aesthetics stand out as the most important factors in flower production and landscaping. Weed control in floriculture and landscaping is critical and costly because maintaining the beauty of the product and the use of herbicides is a low-cost management tool compared to manual management. However, it implies knowing herbicide selectivity, as ornamental species may present some injury depending on the active ingredient and the degree of selectivity of the compound. Because the use of this practice in flower production and landscaping both abroad and mainly in Brazil is incipient, aspects of selectivity, chemical weed control, and safe application of different herbicides are addressed in this paper.
