شناسایی فلور علف های هرز مزارع گندم آبی و دیم شهرستان باوی

Wheat has a very important role in food security as it is the largest crop in terms of area under cultivation. Khuzestan is known as the main producer of wheat with over 650 thousand hectares. One of the detrimental factors is the presence of weeds, which can vary depending on the climate and the conditions of the soil. To identify the weed flora of irrigated and rainfed wheat fields, samples were taken from Bavie County fields. The results showed that the most dominant species of weeds in rainfed were from the weedsBrassicaceae family ) Eruca sativa, Hirschfeldia incana and Ammi majus(and the density of Eruca sativa was higher than other weeds. In addition, two important post-harvest weeds were identified in rainfed fields: Carthamus tinctorius and Alhagi maurorum. Lolium persicum, Alopecurus myosuroides, Phalaris minor, and Avena spp. were the most dominant grass weed species. Among broadleaves, Malva neglecta, Sinapis arvensis, Beta maritima, Ammi majus, Convolvulus arvensis and Silybum marianum had the highest density. In some of the wheat fields, Scorpiurus muricatus and Spergularia marina were found in abundance as weeds. The lack of control of ryegrass, the dominant weed, with ACCase and ALS inhibiting herbicides was the main problem in the irrigated fields. Weed identification can be effective in integrated weed management, especially in chemical control and appropriate selection of herbicides to control a wide range of weeds.
