“…In the last decade, the achievements of nanotechnology in the development of pesticide formulations have been actively discussed. This mainly applies to nanoparticles, the nanoscale analogs of CRFs [ 104 ]. Nanoformulations may include the components that release AI under certain conditions, for example, at a given pH level, illumination, temperature, and humidity, as well as in the presence of certain plant enzymes [ 105 ].…”

Weeds are a permanent component of anthropogenic ecosystems. They require strict control to avoid the accumulation of their long-lasting seeds in the soil. With high crop infestation, many elements of crop production technologies (fertilization, productive varieties, growth stimulators, etc.) turn out to be practically meaningless due to high yield losses. Intensive use of chemical herbicides (CHs) has led to undesirable consequences: contamination of soil and wastewater, accumulation of their residues in the crop, and the emergence of CH-resistant populations of weeds. In this regard, the development of environmentally friendly CHs with new mechanisms of action is relevant. The natural phytotoxins of plant or microbial origin may be explored directly in herbicidal formulations (biorational CHs) or indirectly as scaffolds for nature-derived CHs. This review considers (1) the main current trends in the development of CHs that may be important for the enhancement of biorational herbicides; (2) the advances in the development and practical application of natural compounds for weed control; (3) the use of phytotoxins as prototypes of synthetic herbicides. Some modern approaches, such as computational methods of virtual screening and design of herbicidal molecules, development of modern formulations, and determination of molecular targets, are stressed as crucial to make the exploration of natural compounds more effective.

Weeds are a permanent component of anthropogenic ecosystems, which requires strict control to avoid the accumulation of their long–lasting seeds in the soil. With high crop infestation, many elements of crop production technologies (fertilization, productive varieties, growth stimulators, etc.) turn out to be practically meaningless due to high yield losses. Intensive use of chemical herbicides (CH) has led to undesirable consequences: contamination of soil and wastewater, accumulation of their residues in the crop, the emergence of CH-resistant populations of weeds.

“…Different nanoparticle formulations are used in agriculture as herbicides, insecticides, fungicides, acaricides, fertilizers, and growth regulators, among others [36]. Several studies have demonstrated the potential of formulations of biopesticides associated with polymeric nanoparticles [13]. Silver nanoparticles (AgNPs) represent a powerful eco-friendly pest management alternative and an improved crop production material.…”

Background Insects withstand foreign substances and infection by expressing robust defense responses, which are mediated by hemocytes, fat body, midgut, and many other tissues. The Egyptian cotton leafworm, Spodoptera littoralis (Boisduval), is a polyphagous pest with considerable economic importance in Egypt and globally. Many control strategies were employed to control this pest. Nowadays, there is a trend to use nanotechnology tools in agricultural practices as they balance minimal concentration and maximum pest control, safe concentration, and reduce the cost of pest control. The present study aimed to evaluate the hematological and histopathological response of S. littoralis larvae post-treatment with sublethal concentrations of emamectin benzoate and its nanoform, besides the silver nanoparticles. Results The results revealed the high toxicity of emamectin benzoate and its nanoform (LC50 values were 0.0524 and 0.023 ppm, respectively). The results also showed that all tested compounds significantly influenced the mean number of laid eggs/female. The emamectin benzoate nanoform (837.3 ± 52.09) was the most efficient compound compared to the control (1999.3 ± 46.5). The hematological responses against the EMB + AgNP were lowered total hemocyte counting (22.41 ± 1.3) compared to the untreated larvae (38.08 ± 0.83). In addition, there were some histopathological changes in the midgut tissues. They were represented as destroying the integrity of the epithelial cells and the ciliated border. The columnar cells began to disintegrate, and the peritrophic membrane became vacuolized. In contrast, the cuticle layers were not affected by various treatments. Conclusion We can conclude that the employment of emamectin benzoate, either in its original form or as its nanoform, is considered a promising substitute for conventional insecticides. The nanoform of emamectin benzoate proved its high efficiency against the larvae of the cotton leafworm, which may allow the application of this formulation at low concentrations.
