“…Introduction of non-tilled systems provokes changes in nature and distribution of SOM in the soil profile. Other variable characteristics of the soil profile that may modify the persistence and mobility of atrazine are the pH (Weber et al, 1993;Weber 1995;Houot et al, 2000), the content and type of clay (Laird et al, 1992;Barriuso et al, 1994;Celis et al, 1997), the availability of carbon and nitrogen (Abdelhafid et al, 2000a) and the water content (Reinhardt & Nel, 1993;Koskinen & Rochette, 1996).

Summary Atrazine behaviour was investigated in the different pedological horizons from profiles of two non‐tilled soils, a Typic Argiustoll and an Entic Haplustoll from the Argentinean pampas. As atrazine use in field conditions was associated with maize cropping, only one type of soil received atrazine every other year. Atrazine behaviour was characterized through the balance of 14C‐U‐ring atrazine radioactivity among the mineralized fraction, the extractable fraction and the non‐extractable bound residues. The composition of the extractable fraction was characterized. Atrazine mineralization was the main dissipation mechanism in the superficial horizon of the Argiustoll because of microbial adaptation after repeated atrazine applications. In contrast, little atrazine mineralization was found in the Haplustoll profile, and it decreased with depth. The capacity of the soil organic matter to form bound residues was characterized using soil‐size fractionation. Atrazine‐bound residues depended on the soil organic matter content and the size of the fraction. Organic matter in the largest size fractions had a higher capacity to form atrazine‐bound residues. In the Argiustoll profile, the atrazine degradation capacity decreased in the subsurface horizons (Bt1 and Bt2), where a large part of bound residues were formed. The deepest horizon (BC) of this profile had a high capacity to degrade atrazine reaching this horizon after a lag period. In the Haplustoll profile, atrazine mineralization and bound residue formation followed the organic carbon mineralization pattern.

“…This safe interval is rather variable, given that it depends on several factors, such as the crop species, the physico-chemical characteristics of the soil and climatic conditions. 54,55 For example, the high sand percentage and low organic matter content of the soil used in the present study are probably related to the intense residual effect detected here, as the low atrazine sorption to soil organic and inorganic particles increases the herbicide availability to the plants. 56 Although the current results, together with previous studies of our group, 15,20,22 have shown satisfactory control of different plant species by nanoatrazine, field experiments with mixed weed populations are essential to verify the efficacy of this nanoformulation under realistic conditions.…”

“…In summary, our results indicate that the tested nanoformulation could be applied for efficient weed control without additional phytotoxicity to susceptible crops compared with the non‐nanoatrazine formulation, provided that a safe interval from herbicide application to sowing is respected.

BACKGROUND Poly(ϵ‐caprolactone) nanocapsules (NC + ATZ) are an efficient carrier system for atrazine and were developed as an alternative to reduce the harmful environmental effects of this herbicide. Here, we analyzed the pre‐emergence herbicidal activity of NC + ATZ against Bidens pilosa and evaluated its residual effect on soybean plants after different periods of soil treatment with the formulations. RESULTS In contrast to non‐nanoatrazine, NC + ATZ treatment led to very high mortality rates of B. pilosa seedlings even after a tenfold dilution, which suggests that atrazine nanoencapsulation improved its pre‐emergence herbicidal activity. In a short‐term assay (17 days), soil treatment with all atrazine‐containing formulations resulted in intense toxicity to soybean plants. NC + ATZ at 200 g ha−1 had the same inhibitory effects on the physiological and growth parameters of soybean plants compared with non‐nanoatrazine at 2000 g ha−1, which suggests that atrazine nanoencapsulation increased the short‐term residual effect of the herbicide. In a long‐term assay (60 days), a gradual recovery of soybean plants from atrazine phytotoxicity was observed. When comparing the effects of nano‐ and non‐nanoatrazine at the same concentrations, the growth and physiological parameters of soybean plants were mainly affected to the same extent. This indicates that encapsulation of atrazine into poly(ϵ‐caprolactone) nanocapsules did not enhance the long‐term residual effect of the herbicide on soybean. CONCLUSION NC + ATZ could be applied for efficient weed control without additional phytotoxicity to susceptible crops compared with non‐nanoatrazine, provided that a safe interval is respected from atrazine application to sowing. © 2019 Society of Chemical Industry

“…However, the understanding of this effect is very complicated [26]. Generally, the degradation of herbicides in heavy soils is faster than in light soils [27]. Kucharski and Sadowski [28] found that the degradation of ethofumesate was faster in medium silty loam soil than loamy sand soil.…”

Environmental pollution is one of the most critical issues concerning the quality of the environment and threatens the human safety due to bioaccumulation. The extensive application of pesticides causes great public concern about the negative impacts on the environment and human health. Herbicides have been used for weed management and to prevent the yield loss of agricultural products. In recent years, the environment's quality is extensively considered due to the enormous pesticide application in agroecosystems. There are some different pathways for the degradation of herbicides in the environment, including biodegradation, chemical degradation, photodegradation, uptake by target or non-target plants, adsorption to soil particles and leaching. Assessing the environmental risks of herbicides before mass production, commercialization, and distribution is very important. The presence of herbicide residues in the environment has become a fundamental problem in many countries. Bioassay and analytical methods could identify, detect, and quantify herbicide residues in the environment. In this review paper, the fate, detection methods, and effect of herbicides on non-target plants have been discussed.
