Efficient and effective methods of weed control are needed to ensure higher crop productivity and profitability. Herbicides use is becoming popular amongst farmers because of ease, efficiency and lesser cost involved. The efficacy of herbicide depends on the proper spraying technique. Recently, the new generation effective low-dose high-potency (LDHP) herbicide molecules are being introduced but their compatibility to the existing spraying techniques and practices is unknown. Hence, it is necessary to standardize existing spraying technique for LDHP molecules. Thus, to standardize the existing spraying technique with two LDHP molecules (bispyribac-Na and clodinafop + metsulfuron), a field experiment was conducted for two years (2016-18) in rice during Kharif season and wheat Rabi season. The post-emergence (PoE) application of LDHP molecules, viz . bispyribac-Na at 25 g/ha in rice and clodinafop + metsulfuron at 60 + 4 g/ha in wheat were tested with flat fan (FF) and floodjet (FJ) nozzles using spraying volume of 250 and 500 l/ha. The weed control efficiency (WCE) obtained with different spray volume and nozzles usage was on par. The maximum WCE of 76% in rice and 89% in wheat was observed. A spray volume of 250 l/ha with either FF or FJ nozzle effectively controls the weeds and increases the field capacity by 60-100%.

Several plants express the allelopathic phenomenon through release of allelochemicals. Plants rich in allelochemicals can be used for controlling weeds in organic crop production. Current study was aimed at screening of Andrographis paniculata (Burm.f.) Nees (bitter weed), Plectranthus amboinicus (Lour) Spreng (Indian borage) and Tagetes minuta L.(Southern cone marigold) for allelopathic potential against upland weeds.This study was conducted from February to May 2021 in the Department of Agronomy, College of Agriculture, Vellanikkara, Kerala Agricultural University, Thrissur. The methanol extracts of Tagetes minuta and Andrographis paniculate at 25-30% concentration as pre-emergence application exhibited allelopathic effect on broad-leavedweeds.
一些植物通过释放化感物质来表达化感现象。在有机作物生产中,利用富含化感物质的植物防治杂草是可行的。本研究旨在筛选穿心莲(Andrographis paniculata,缅甸)。Nees(苦草),Plectranthus amboinicus (Lour)春季(印度琉球苣苔)和Tagetes minuta L.(南方锥金盏花)对陆地杂草的化感作用潜力。该研究于2021年2月至5月在特里苏尔喀拉拉邦农业大学维拉尼卡拉农学院农学系进行。万花菊和穿心莲甲醇提取物在25 ~ 30%的浓度下对阔叶杂草有化感作用。
