A field experiment was conducted in Kanan region, province of Diyala, Iraq during the winter season 2016-2017 to screen herbicides for wheat cultivation. Six herbicides viz., Salix, Cronus, Pallas, Granstar, Topic and Atlantis were sprayed as post-emergence with second irrigation 54 days after crop sowing. Wheat growth parameters viz Crop height, Spike length and number of grains per spike were a higher in Granstar&Topic (105.2 cm, 12.6 cm, 51.4) respectively, 1000 grain weight were noted with Atlantis (40.9 g). followed by Granstar&Topic (39.2 g), Number of plants / m2 was a higher in Atlantis (430), Grain yield g \ acre was significantly increased in Granstar&Topic (1848 g) weeds growth parameters like Number of weeds / m2, Dry weight of weeds g, Weed control % and Weeds inhibition % were lower in Salix&cronos (0.0,0.0 g,100%,100%) respectively.

<p class="R-AbstractKeywords"><span lang="EN-GB">Integrated weed management (IWM) is a complex approach to weed control that is based on use of several different methods complementing each other, instead of relying on one single method, like chemical weed control. Weed control methods that can be used as parts of IWM strategy include mechanical weed control, application of herbicides, low tillage, changes in the rate and application time of fertilizers, use of undersown crops and crop rotation. Weed surveys were carried out in 2013 and 2014 in the southeastern part of Latvia. The aim of this study was to assess the effect of crop rotation and other field management practices on weed density and weed species composition using the data collected in the surveys. Survey was carried out in the arable fields of conventional farms within four different size categories. One of the significant factors that explained the variation of weed composition within a field was a proportion of cereals in crop rotation within a four year period. Further surveys are required to estimate the effects of climatic variables. Density-dependence can also be important for practical management decisions for particular weed species and should be investigated.</span></p>

The sweetpotato (Ipomoea batatas (L) Lam) crop once established requires little field management apart from weed control Currently weeds are minimised by a combination of handweeding interrow cultivation and the application of paraquat (100 g ai/ha) over the crop In this study alternative herbicide treatments were examined in a field trial Handweeding produced the highest marketable yield (267 t/ha) significantly more than all other treatments apart from acetochlor (24 kg ai/ha) which produced 218 t/ha (P
