“…Agrochemicals applied to paddy fields easily flow out with water either across soil surface (runoff) or into soil profile (leaching) and may prove fatal to the environment. Runoff rate from paddy fields depends on physical and chemical properties such as octanol–water partition coefficient, which determines the lipophilicity or hydrophilicity, water solubility of the herbicide, and adsorption capacity of soil (Devi et al, 2019; Sudo et al, 2012). Heavy rainfall causes intense leaching and surface runoff due to higher water solubility of pretilachlor (Comoretto et al, 2008; Nakano et al, 2004; Sondhia, 2014).…”

“…Leaching potential decreased in soil with application of farm yard manure. High clay and organic content also decreases leaching due to their strong adsorption capacity (Devi et al, 2019; Kaur & Kaur, 2018).…”

“…Dissipation of herbicides in soil is majorly due to the microbial degradation (Adachi et al, 2007; Ashton, 1982; Devi et al, 2019). The large herbicidal persistence in soil directly influences the soil microorganisms, which in turn affects the plant growth (Raipuria & Parveen, 2016).…”

Herbicides are applied for effective weed management in order to increase the crop yield. In recent decades, the overuse of these chemicals has posed adverse effects on different biotic components of the environment. Pretilachlor has been widely used during last few decades for weed management in paddy crop. Its excessive use may prove fatal for environment, various organisms, and nontarget plants. Thus, it is pertinent to know the extent to which herbicide residues remain in environment. The potential mobility and the release rate of herbicide in the soil are important factors governing ecotoxicological impact and degradation rate. Therefore, several techniques are being investigated for its effective removal from the contaminated sites. Furthermore, efforts have also been made to study the degradation of pretilachlor by various physicochemical processes, resulting into the formation of different types of metabolites. This review summarizes the available information on environmental fate, various degradation processes, microbial biotransformation, metabolites formed, ecotoxicological effects, techniques for detection in environmental samples, effect of safener, and various control release formulations for sustained release of pretilachlor in applied fields. The information so obtained will be very advantageous in deciding the future policies for safe and judicious use of the herbicide by maintaining health and environmental sustainability.

“…Rice is the most widely consumed food for a high proportion of global population, especially in Asia. It is necessary to confirm whether these chemicals are dissipated from the environment soon after their mission is accomplished [ 22 – 25 ]. According to the growing environment of rice plants, the dissipation of pesticides is definitely a complicated process [ 26 ].…”

Indoxacarb is a broad-spectrum insecticide and widely used in agriculture. The dissipations and residues of indoxacarb were researched at three different field sites in Beijing, Hunan, and Zhejiang provinces in China. Analytical methods for determining the residue of indoxacarb in paddy water, paddy soil, rice straw, rice hull, and brown rice were described. Indoxacarb residues were extracted from samples, cleaned up by solid phase extraction, and determined by high-performance liquid chromatography coupled with tandem mass spectrometry in the selected ion monitoring mode. The recoveries in paddy water, paddy soil, rice straw, rice hull, and brown rice matrices at three spiking levels ranged from 79.7% to 98.3%, respectively. The field and environmental conditions would affect the dissipations and residues of indoxacarb. The time to dissipate 50% of indoxacarb in paddy water, paddy soil, and rice straw was less than 9 days. The terminal residues obtained from Beijing at preharvest interval of 14 and 21 days were higher than the maximum limit of European Union. Therefore, a dosage of 24 g a. i. ha−1 at 28 days preharvest interval with 3 spraying times was recommended. Such accumulation of measured data is necessary to provide guidance for the proper and safe use of this pesticide.
