“…Previous studies have shown that Pre was harmful to nontarget organisms, 47 and had phytotoxicity on rice. 36 To further study the feasibility and safety of AD-67@Pre@ZIF-67 application in the paddy field, rice was used as the test plant, and the effective component concentration was 400 g a.i.…”

“…9 Therefore, AD-67@Pre@ZIF-67 can be released in the environment in a more controlled way, the simultaneous release of AD-67 and Pre reduces the risk of Pre toxicity to rice, providing a longer protection advantage than the traditional pesticide formulations. 47…”

“…26 Therefore, there is an urgent need to develop effective herbicide formulations with negligible impact on non-target environments. 27 Notably, using Pre can cause phytotoxicity to crops, such as rice plants, negatively affecting plant height, root length, fresh weight, and even product yield. 28 Herbicide safeners are agrochemicals used in combination with herbicides to reduce phytotoxicity and improve the selectivity of herbicides, without affecting their herbicidal effects.…”

“…Microencapsulation technology can give existing materials new various functions such as protection and isolation of active ingredients from their external environment and controlled release 4–6 . Therefore, microencapsulation technology is one of the most effective methods of pesticide formulation and have been used for several decades not only in agrochemicals 7–10 but also in other fields such as food, cosmetics, textiles and pharmaceuticals 11–13 …”

Preparation of Fosthiazate (FTZ)-loaded microcapsules with controlled release was attempted by the interfacial polymerization using toluene diisocyanate (TDI) and triethylenetetramine (TETA) as monomers. The effects of the monomer concentration and the monomer concentration ratio on characteristics of the microcapsules such as size, shell thickness and release behavior in water and in soil were studied. In the study, FTZ was successfully encapsulated into a polyurea resin, and the characterization revealed that the microcapsule shell became thicker proportionally to the applied monomer concentration. The release rate of FTZ from the microcapsules in water was mostly proportional to the ratio of the surface area to the shell thickness of the microcapsules, and the release rate fitted the first-order kinetic model. On the one hand, when TDI concentration was low or the monomer concentration ratio was high, the release rate was significantly increased owing to the formation of insufficient microcapsule shell and the coarseness of the shell. Moreover, the slower the release rate in water was, the higher residual ratio of FTZ in soil could be maintained. However, it was also observed that the release rate in soil was faster than that in water. It is suggested that the constant replacement of water around the microcapsules accelerated the release rate, or the microcapsule particles migrated through the soil. These results indicated that FTZ-loaded microcapsules with controlled release were able to be prepared. In addition, basic findings about the relationship and the difference between the release behaviors of FTZ-loaded microcapsules in water and in soil were obtained.

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.
