Background: Generally, farmers cultivate clusterbean [Cyamopsis tetragonoloba (L.) Taub] on rainfed area but seldom adopt weed control practices in it. It becomes very difficult and uneconomical to maintain free environment throughout crop period the field under conditions. Therefore, current study was aimed find an effective practice Methods: Effect of management with T1: Pendimethalin @ 1 lit...

The present study was carried out at Regional Research Station, CCS Haryana Agricultural University, Karnal, during winter (rabi) seasons of 2019–20 and 2020–21. In this experiment, ZT-wheat (Triticum aestivum L.) sown with happy seeder under surface residue load 6 t/ha (chopped). Fourteen weed control treatments including pre-emergence herbicide (pendimethalin 1500 g/ha), sequential applicatio...

Background: The presence of weeds in cowpea reduced the yield to tune 60-82% depending on weed flora and density. critical period competition was 20-25 DAS. Therefore it is essential control effectively harness maximum potential crop. To manage also important determine efficacy pre post-emergence herbicides. Sequential application herbicides a short duration crop not only increases cost product...

Understanding the impacts of herbicides on soil microbial communities is important, as these organisms mediate a wide range ecosystem services. Here, we investigated whether diversity and function were significantly influenced by one-off applications atrazine, diuron, fluazifop-P-butyl, haloxyfop-P-methyl pendimethalin pure compounds at their recommended doses over multiple time points (1, 3, 7...

BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable as a consequence of soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides, flufenacet and pendimethalin, against Alopecurus myosuroides and investigated the implications of variation in organic matter for weed management using a crop-weed competit...

Background: Groundnut or peanut (Arachis hypogaea L.) is known as the ‘king’ of oilseeds. It one most important food and cash crop India. Among different constraints that limit productivity groundnut, weed menace serious bottlenecks. A field experiment was conducted at Perunthalaivar Kamaraj Krishi Vigyan Kendra, Puducherry during 2019 to 2020 study tank mix application post-emergence herbicide...

The persistent organic pollutants (POPs) due to their physicochemical properties can be widely spread all over the globe; as such they represent a serious threat to both humans and wildlife. According to Stockholm convention out of 24 officially recognized POPs, 16 are pesticides. The atmospheric life times of pesticides, up to now were estimated based on their gas-phase reactivity. It has been...

The carry-over effect of sub-lethal herbicides was investigated on the germination of seeds collected from surviving Chenopodium album plants, which had received 1/8, 1/8 twice, 1/8 three times, 1/4, 1/2, 1/1 doses of either pre-emergence ioxynil or post-emergence bentazone in a previous onion (Allium cepa) crop. Seeds were also collected from surviving C. album plants, which had received 1/4, ...
