“…Companies such as Biomer, Danimer Scientific, and GreenBio have ventured into the commercial production of PHAs, particularly in agricultural applications such as mulch and bags for germination and seedling growth. Additionally, the use of these polymers has been reported in the manufacturing of slow-release particles for chemicals like fertilizers, pesticides, and herbicides. − …”

In the 21st century, global agriculture confronts the urgent challenge of increasing food production by 70% by 2050 while simultaneously addressing environmental and health concerns. Plastics, integral to agricultural innovation, present sustainability challenges due to their non-biodegradable nature and contribution to pollution. This perspective examines the transition to bioplastics, emphasizing their bio-based origin and their crucial characteristic of being readily biodegradable in the soil. Key bioplastics such as poly(lactic acid) (PLA), polyhydroxyalkanoates (PHAs), and biomass-derived polymers are discussed, particularly regarding the microplastic generation in soil resulting from their use in specific applications like mulch films, delivery systems, and soil conditioners. Embracing bioplastics signifies a significant step forward in achieving sustainable agriculture and addressing plastic waste. However, it is highlighted that while some bioplastics can be recovered and recycled, special applications where the plastic is in intimate contact with soil pose challenges for recovery. In these cases, that represent more than the 50% of plastics used in agriculture, meticulous design for biodegradation in soil synchronized with agricultural cycles is necessary. This approach ensures minimal environmental impact and promotes a circular approach to plastic use in agriculture.

“…The use of biodegradable polymers is one of the top priorities in carrier development. Positive results of research and application for deposition and slow release of pesticides of different natures have already been discovered for natural polymers such as cellulose, starch, alginate, albumin or gelatin, 107 polyhydroxyalkanoates, 108,109 lactic and glycolic acid copolymers, polycaprolactone, peat, clay, etc. 110−112 Studies on controlled delivery of active ingredients to combat PCNs are still limited in number, but papers on depositing nematicides for controlling nematodes of various species have been published.…”

Potato cyst nematodes (PCNs) pose a great challenge for potato cultivation throughout the world. Being a rather difficult parasite due to a number of its physiological features, specifically a long-term viability of the eggs, PCNs cause drastic damage to worldwide agriculture. There are several approaches to prevent the spread of these pests, primarily using synthetic nematicides as well as biological products on a bacterial and fungal basis and application of agrophytocenotic methods. However, each of these conventional approaches has its considerable disadvantages. As a result, given the high yield losses caused by PCNs and the limited efficacy of conventional approaches to deal with this problem, a new means of pest control needs to be sought and researched. Development of long-acting preparations deposited with nematicidal ingredients could be a novel prospective approach for PCNs management.

“…Polyhydroxyalkanoates (PHAs)degradable microbial polymers are among the most promising materials for fabricating formulations to protect crops from weeds and pathogens. The slowrelease formulations of pesticides embedded in PHA matrices described in the literature include fungicides 22 ; herbicides [23][24][25][26][27][28] ; insecticides. 29 Jiangsu Chongqing Agrochemical (China) developed and started the production of the highly effective fungicide fenoxanilloaded into P(3HB) microcapsules, which showed high parameters of controlled release and reduced environmental toxicity of the fungicide.…”

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.
