    Chemical wastes in particular wastes obtained from pesticides production are very dangerous, so control and recovery of them has attracted attention of many researchers and environmental organizations in recent years. Wastes in butachlor industries are formed under undesirable conditions in the process and also during filtration step and cause serious problems. In this study, recovery of butachlor from waste and its effects on rice plant was investigated. Material and Methods: Waste and off-spec samples containing 55.8% and 63.3% butachlor, respectively, were subjected to solvent extraction. GC/MS and FT-IR were used to identify components of the extracts. The determination of butachlor recovered from waste and off-spec samples was carried out by HPLC and its amount was found to be 88.4% and 89.7%, respectively. Field tests were done on the rice plants to investigate using recovered samples in rice fields. The treatments were exposed at 1.5 Kg active ingredient / hectare of recovered butachlor, waste, off-spec and commercial samples. Results and Discussion: The phytotoxicity degrees of both waste and off-spec samples were 100% and the plants died after 28 days. The phytotoxicity degrees of commercial and recovered butachlor from waste and off-spec samples were 6.5, 8.5 and 8% under the same conditions, respectively, which indicates that the recovered butachlor can be used as effectively as the commercial sample in rice fields.

  4 - Persistance of Metribuzin in Soils with Different Characteristics and Utilization History and Their Effects on Cultivated Oat (Avena sativa L.)

  This experiment was conducted to study the effect of metribuzin on cultivated oat in soils with different characteristics and utilization history as factorial on the base of randomized complete block design with three replications in Institue of Plant Protection in 2012 More

  This experiment was conducted to study the effect of metribuzin on cultivated oat in soils with different characteristics and utilization history as factorial on the base of randomized complete block design with three replications in Institue of Plant Protection in 2012. First factor was soil type in six levels (Hamedan with 15 years and without utilization history, Jiroft with 15 years and without utilization history, Isfahan with 2 years utilization hisrory and Mashhadwith 3 years utilization history) and second factor was different amounts of metribuzin in six levels (0, 0.1, 0.3, 0.7, 1 and 1.5 kg/ha). Three months before cultivating, the pots with mentioned soils were treated with metribuzin and were irrigated every three days. Then oat seeds was cultivated in pots and harvested after four weeks. Shoot length, root lenght, shoot wet weight and root wet weight was measured and dose- response curves were drawn. According to results, more oats were burned due to increase of herbicide amounts, but the effects of metribuzin residue were decreased by increase of amounts of clay, organic matter and utilization history. The highest and lowest phytotoxicity was observed in soils of Jiroft without utilization history and Hamedan with 15 years utilization history, respectively. Manuscript profile

  This study was designed in order to investigate the allelopathic effect of olive fruit pomace on some physiological parameters and yield of three wheat cultivars (Triticum aestivum). A pot experiment was used based on a factorial study with completely randomized design and three replications at five levels (0, 1, 3, 5, and 7 % W/W) of olive fruit pomace and three wheat cultivars (Triticale, Karkhe and Chamran). The amount of soluble proteins of leaf, activities of peroxidase, ascorbate peroxidase, and catalase enzymes of leaf, and amount of malondialdehyde of leaf at ear emergence stage and spike weight, spike length, grain number per spike, grain weight per spike, 1000 grain weight, total harvest index, grain proline content, and grain soluble carbohydrate content at complete ripeness stage of wheat were measured. According to the results, amount of soluble proteins of leaf, activity of peroxidase of leaf, spike weight, spike length, grain number per spike, grain weight per spike, 1000 grain weight and total harvest index decreased in the three wheat cultivars with an increase in the content of olive pomace in the soil compared to the control. But the amount of activity of ascorbate peroxidase and catalase enzyme of leaf, amount of malondialdehyde of leaf, grain proline, and grain soluble carbohydrate content showed increase in the three wheat cultivars by increasing the content of olive pomace in the soil compared to the control. Since olive fruit pomace contains phenolic compounds, the inhibitory effects of olive pomace on wheat growth are attributed to these compounds.   Manuscript profile
