Abstract:

Pretilachlor poisoning in humans is an understudied area. It is widely used as a herbicide in India; hence it is of paramount importance that we understand the various clinical presentations from its toxicity. Acute oral intoxication of pretilachlor can present with neurological and gastrointestinal manifestations. This case report adds to the scant evidence on how to recognize and manage pretilachlor toxicity

Abstract The influence of individual or combined treatments of the chloroacetanilide herbicide pretilachlor and the safener fenclorim on glutathione content and the activity of glutathione reductase (GR, EC 1.6.4.2) and glutathione-S-transferase (GST, EC 2.5.1.18) of rice (Oryza sativa L., var. Lamont) was investigated in a time-course study including 0, 12, 24, 48, and 72 h periods after treatment. Pretilachlor applied alone at 2 μM did not influence the levels of total or reduced glutathione of germinating rice seedlings. Fenclorim applied alone at 20 μM increased significantly the levels

Abstract:

Pretilachlor is a chloroacetamide herbicide mainly used for weed and broadleaf weed control in rice, that is widely utilized in China. In order to detect the residue of pretilachlor in the environment and food, a highly sensitive and specific monoclonal antibody (mAb) against pretilachlor was prepared, and the half maximum inhibitory concentration (IC50) of the monoclonal antibody was validated to be 31.47 ± 2.35 μg/L. An indirect competitive ELISA (ic-ELISA) based on the antibody with a linear range of 6.25~100 μg/L was developed. The specificity of the antibody was explained by computer simu

Weedy rice (Oryza sativa f. spontanea) is a serious problem in rice-producing areas. The objective of this study was to evaluate the effect of the safener fenclorim on rice seed germination and yield when used in conjunction with the pre-emergent herbicide pretilachlor in the growth chamber and in the field. Rice seed germination was accelerated by soaking seeds in fenclorim (0.67 g L−1), and pretilachlor (0, 450, 900, 1800, 3600 and 7200 g a.i. ha−1) was applied 1, 3, 6, 12,

Abstract:

Weedy rice poses a formidable challenge in rice cultivation due to its genetic similarity to cultivated rice, making selective herbicides less effective in controlling it without causing harm to the cultivated rice. The potential use of pre-emergent herbicides before rice sowing to inhibit emergence and growth of weedy rice seedlings in the soil remain unknown. Thus, this study aimed to evaluate the responses of weedy rice towards selected pre-emergent herbicides under different soil water conditions and to identify the optimal timing for rice seed sowing following the application of pre-emerg

At Banganga, Kapilbastu, Nepal, a field experiment was conducted in the spring of 2021 to determine the performances of transplanted spring rice under different weed management techniques. With five treatments and four replications, the experiment was structured as a single-factorial Randomized Complete Block Design (RCBD). The treatments consisted of Pretilachlor 50% EC (dose: 500 ml a.i. per acre) as pre-emergence herbicide, Pretilachlor 50% EC (dose: 500 ml a.i. per acre) as pre-emergence herbicide plus hand weeding at 20, 40 DAT, Hand weeding at 20 DAT, 40 DAT, 60 DAT, Cono-weeding at 20 D

A field experiment was conducted in a randomized block design during the rainy (kharif) season of 2012 at Pantnagar, Uttarakhand, to evaluate the effect of different weed-control treatments on productivity, nutrient deple- tion by weeds as well as uptake by rice (Oryza sativa L.). Weed-management practices significantly influenced yield, nutrient uptake by rice and depletion by weeds. Pre-emergence application of pretilachlor 750 g/ha + no irri- gation up to 1 week followed by (fb) early post-emergence application of bispyribac-Na (20 g/ha) provided broad- spectrum weed-control, resulting in s

Dry direct-seeded rice (DSR) is gaining prominence as a sustainable alternative to conventional transplanting due to labor shortages and water scarcity. However, weed infestation remains a critical challenge in this method, significantly reducing yields. This study evaluates the impact of various herbicide combinations on soil microflora, enzyme activity, nutrient uptake, and weed control in DSR.

Tank-mixing two or more chemical groups of either pre- or post-emergence herbicide may be very beneficial for the efficient control of weeds in a heterogeneous population. There are a few proprietary herbicides (commercial mixtures of two pre- or post-emergence herbicides) on the market, but they are extremely few. In this backdrop, the current research was conducted to investigate the efficacy and rice phytotoxicity of different tank-mix ratios of pre-emergence herbicides to control weeds under zero till non-puddled Boro rice (cv.

Abstract:

Weed is one of the major yield-limiting factors in rice cultivation. It causes yield losses of around 40-90%, depending on the situation. Manual weeding is the dominant weed management method in rice and limited farmers use herbicides in Nepal. Selecting effective herbicides for different weed species is a crucial task for farmers. So, an experiment with 9 treatments consisting of 5 herbicides was conducted in RCB Design with 3 replications during 2020 and 2021 to find effective herbicides. The recommended agronomic practices were followed. Rice variety Khumal 11 was transplanted in a 4m x 3m
