Declines in crop yield due to pests and diseases require the development of safe, green and eco-friendly pesticide formulations. A major problem faced by the agricultural industry is the use of conventional agrochemicals that contribute broad-spectrum effects towards the environment and organisms. As a result of this issue, researchers are currently developing various pesticide formulations using different nanotechnology approaches. The progress and opportunities in developing nanoemulsions as carriers for plant protection or nanodelivery systems for agrochemicals in agricultural practice have been the subject of intense research. New unique chemical and biologic properties have resulted in a promising pesticide nanoformulations for crop protection. These innovations—particularly the nanoemulsion-based agrochemicals—are capable of enhancing the solubility of active ingredients, improving agrochemical bioavailability, and improving stability and wettability properties during the application, thus resulting in better efficacy for pest control and treatment. All of these—together with various preparation methods towards a greener and environmentally friendly agrochemicals—are also discussed and summarized in this review.

The latest trend in agriculture is the development and application of environmentally friendly pesticides with targeted and controlled release of active ingredients embedded in biodegradable polymer bases. In this work, a series of experimental slow-release pesticide formulations was produced using composites of degradable polyester poly(3-hydroxybutyrate) and natural materials as a matrix for embedding two agrochemicals – a fungicide (tebuconazole) and an herbicide (metribuzin). The structure, physicochemical properties and degradation rate of long-term formulations and the kinetics of active ingredient release from the matrix were studied in laboratory soil microecosystems. The experimental formulations allowed for a gradual release of agrochemicals into the soil for two months without abrupt emissions, providing long-term plant protection against pathogens and weeds. In contrast to the free forms of the agrochemicals, the analysis showed an absence of noticeable shifts and negative impacts on soil bacterial communities with the introduction of the developed formulations. The fungicidal action of long-term tebuconazole was confirmed on model Triticum aestivum plants infected with a complex of root rot pathogens (Alternaria, Fusarium, and Bipolaris). The efficacy of embedded metribuzin on model Melilotus albus weeds was comparable to that of the free forms of this herbicide. This work has produced new data on biodegradable polyhydroxyalkanoates for constructing long-term formulations of agropreparations. The fundamentals have been provided for constructing environmentally friendly and targeted controlled-release formulations of crop protection products against pathogens and weeds

The agricultural sector of Asian countries supports 60% of the global population, accounting one-fifth of the world’s agricultural land. Despite the gap between demand and supply of food is gradually increasing due to the damages caused by insect and other pest attacks on the limited agricultural land, the pest attack has influenced the entire agriculture sector either directly or indirectly, causing socioeconomic losses. To combat, farmers have been using conventional agrochemicals nonjudiciously that lead to adverse effects such as pesticide resistance, environmental contamination, and non-target toxicity. In this regard, new-generation agrochemical formulation techniques are advantageous over conventional pesticides and play a vital role in sustainable agriculture by fulfilling the demand of over-rising food supply to feed the increasing population. These formulations exhibit desired bio-efficacy at lower doses and have minimum possibility to leave pesticide residues in crop products and the environment. Institute of Pesticide Formulation Technology (IPFT), Gurugram, is one of the leading institutes in Asia, which is actively engaged in developing new-generation formulations to deliver safer, efficient, and environment-friendly pesticide formulations. So far, IPFT has developed 60 pesticide formulations and transferred technologies to different agrochemical industries globally. The new-generation formulations developed by IPFT mainly include microemulsion, nanoemulsion, capsulated suspension, nano-encapsulation, an emulsion in water, mixed formulations including several botanical pesticide formulations. The new advancement in pesticide delivery systems is very supportive in combating the crisis faced by the agricultural sector. In this chapter, formulation of different new-generation pesticides and their advancement are summarized.

Crop protection on major crops is now required to follow the principles of integrated pest management so the timing and accuracy of any application of a pesticide or biopesticide has to be more precise to minimize adverse effects on non-target species. The development of UAVs (unmanned aerial vehicles) provides a means of providing a more targeted application of the correct dose, especially by using formulations that are more persistent, thus minimizing loss of spray in areas subject to rain. Avoiding use of too high a dosage allows greater survival of natural enemies and reduces the selection pressure for pests becoming resistant to specific modes of action. The downward flow of air from a UAV should also provide better distribution and impaction of droplets within a crop canopy, reduce soil impaction caused by taking heavy loads of spray applied with 200 l ha–1 of water, and allow treatments when fields are too wet to access with ground equipment. In Asia, many smallholder farmers are using a drone in preference to using a knapsack sprayer. According to Matthews, it has been shown that ULV spraying can be effective, but it needs a narrow droplet spectrum with the droplets remaining stable and not shrinking to become too small. Formulation research can reduce the volatility of the spray, hence the success of oil-based sprays. However, instead of petroleum-based oils, there is a chance to develop vegetable oil carriers with micro-sized particle suspensions to deliver low toxicity pesticides in droplets that can be deposited within the crop and not drift beyond the crop boundary. Oil deposits will be less prone to loss after rain so less should be lost in neighbouring ditches and water courses, especially as rainfall patterns are forecast to change. More studies are needed to evaluate the swath for deposition, buffer zones, formulation, nozzle selection, to guide future specific legislation for UAV applications.
