“…They revealed that the reproduction toxicity of Prosaro was explained based on tebuconazole rather than prothioconazole, whereas survival toxicity was predicted based on Prosaro being more harmful to the soil invertebrates than its individual chemicals. Besides, Tebuconazole, among selected herbicides and other fungicides, has a less harmful effect on the soil microbial communities when penetrating into the soil as a slow release formulation, respectively embedded in a biodegradable composite matrix such as polymer poly-3-hydroxybutyrate, rather than as a free pesticide, as demonstrated by Prudnikova et al 51 They tested the free and embedded pesticides at 0.1 mg per g of soil on various strains of polyhydroxyalkanoate degrading bacteria and fungi. Free tebuconazole extensively harmed the abundance and diversity of the microbial soil composition, which did not recover to the untreated control state for 3 months after application.…”

“…In order to reduce the cost of such formulations and make them easily accessible, pesticides were embedded not only into the very expensive pure P(3HB) but also into the polymer filled with inexpensive natural materials (clay, peat, wood flour). The efficacy of formulations was confirmed in vegetable and cereal crops infested by weeds and infected by root rot pathogens 34–41 …”

“…The efficacy of formulations was confirmed in vegetable and cereal crops infested by weeds and infected by root rot pathogens. [34][35][36][37][38][39][40][41] Potato is one of the few industrially significant crops that reproduces vegetatively, is affected and accumulates pathogens in vegetative generations: viruses, bacteria, and fungi. The main source of infection is carbohydrate-rich tubers, which serve as a substrate for the development of pathogenic microorganisms that cause various diseases of this crop.…”

BACKGROUND: For the first time, the biological activity of slow-release fungicide formulations for suppressing potato pathogens deposited in a degradable poly-3-hydroxybutyrate/sawdust base has been obtained and investigated. RESULTS:The slow-release fungicide formulations (azoxystrobin, azoxystrobin + mefenoxam, and difenoconazole) were studied in vitro and in vivo in comparison with commercial analogues. In in vitro cultures of phytopathogens, the deposited fungicides showed an inhibitory effect comparable to commercial analogues, limiting the growth of colonies of Phytophthora infestans, Alternaria longipes, Rhizoctonia solani and Fusarium solan (2.0-2.3 times relative to the negative control). In laboratory experiments, the use of deposited fungicides was accompanied by earlier germination and more active growth of potatoes against the background of a decrease in the area of plant damage and an increase in yield. In the field experiment, the deposited fungicides suppressed the development of Phytophthora and Alternariosis in the rhizosphere during the entire growing season and reduced the area of plant damage by pathogens by 10-15%, which is two times less than in the groups of plants treated with commercial preparations. The higher biological activity of the embedded fungicides ensured the maximum number of tubers undamaged by pathogens and the total yield of 22-23 t ha −1 , which exceeded the yields in the groups with commercial fungicides (18.4-20.8 t ha −1 ). CONCLUSION: The slow-release fungicide formulations deposited in a degradable P(3HB)/sawdust base are effective in protecting potatoes from pathogens and increasing yields and have an advantage over commercial counterparts.

“…Mechanisms of toxicity of pesticides in microorganisms vary depending on the type of chemical and the microbial species exposed to it [41] . The use of free pesticides adversely affected the abundance of soil microorganisms like Pseudomonas, Bacillus, Pseudarthrobacter, Streptomyces, Penicillium, and Talaromyces from 1.4 to 56.0 times for different types of pesticides [42] . Overuse of pesticides affects the abundance of nitrifying bacteria Nitrospira strain 'Nitrospira inopinata' in paddy soils [43] .…”

Pesticides are widely used in modern agriculture to enhance the quantity and quality of yield in an effective and economical manner, leading to improved food security worldwide. Organochlorines, organophosphates, carbamates and pyrethroids are the four major groups of pesticides used. However, with increasing pesticide use, especially in developing countries, the risk of its toxicity caused by them is on the rise. Despite a low per hectare use of pesticides in India, their injudicious use has led to the presence of pesticide residues in both terrestrial and aquatic ecosystems. It has been observed that major riverine ecosystems like Ganges, Yamuna, Cauvery, Tapi and many others show the presence of pesticides in the water column as well as the river bed sediments. Pesticides tend to bioaccumulate in the food chain. Agricultural runoff into aquatic systems raises the risk of exposure of pesticides to non-target species, leading to adverse consequences on the ecosystem. In this review, an attempt has been made to critically review the usage of pesticides in India, their entry into riverine ecosystems and the impact of pesticides on freshwater microorganisms, invertebrates and vertebrates. The review of legislation in India to control pesticide usage shows that proper implementation of the laws is needed on an urgent basis.
