Special Issue Information

Dear Colleagues,

Tropical agriculture uses synthetic pesticides, posing health and environmental dangers. Synthetic agents "pollute" the environment by "raising" agricultural productivity. Nitrogenous fertilizers such as urea and ammonium sulphate increase soil acidity in tropical crops. Tropical agriculture pollutes agroecosystems with pesticides and heavy metals. Synthetic chemicals may quickly penetrate water and food systems, endangering people and other non-target animals. Organic farming protects the environment. Synthetic insecticides in agriculture also reintroduce pests. This terrible circumstance requires a different approach. Plants have developed biological substances to reduce insect harm over millions of years. These bioactive substances are pesticides, antifeedants, insect growth regulators, juvenile hormones, ecdysones, repellents, attractants, etc. Green insecticides may replace chemical pesticides since plant molecules can perform many functions. Plants can be used to produce safe, eco-friendly nanoparticles, according to recent research. Several efforts have been made to create innovative green synthesis methods in recent decades. Living organisms may be used to manufacture nanoparticles for agroindustry and healthcare in many ways.

This Special Issue focuses on managing sustainable agriculture using phytoproduct-based pesticides, insecticides, and environmentally friendly nanoparticles. For this reason, it encourages high-quality studies that span a wide range of disciplines, such as those devoted to agriculture, pest management, vector control, biologically mediated insect management, dynamics of pest and predator populations, plant extracts, phytocompounds, eco-friendly nanoparticles, and sustainable agricultural practices. Articles and reviews based on original research are welcome.

Effects of Certain Pesticides on the Predatory Mite Typhlodromus ndibu Pritchard and Baker (Acari: Phytoseiidae)

Typhlodromus ndibu Pritchard and Baker (Acari: Phytoseiidae), collected from citrus orchards in the southern region of Vietnam, has been identified as a natural enemy of the citrus red mite Panonychus citri (McGregor) (Acari: Tetranychidae). It holds potential as a laboratory-reared predator for biological control purposes. However, the research on T. ndibu remains limited. This study focuses on investigating the effects of fenpyroximate, alpha-cypermethrin, pymetrozin, buprofezin, matrine, and azadirachtin on this predatory mite in laboratory conditions. Fenpyroximate was the most toxic substance against T. ndibu, affecting its fertility, egg-hatching rate, and population establishment ability. The mortality rate among adult female T. ndibu is (73.97 ± 2.43%), and (89.09 ± 0.00%) in the immature stages after 72 h of exposure to fenpyroximate. Matrine and azadirachtin—active ingredients of plant origin—were classified as slightly harmful to T. ndibu with mortality rates among adult females and the immature stages being less than 50%. The implications of the obtained results regarding the integration of biological and chemical control methods may facilitate the more effective development of integrated pest management (IPM) programs.

Pesticides have been widely used in agriculture, resulting in significant pollution that affects both the environment and human health. This pollution is particularly prevalent in nearby agricultural areas, where sensitive resources are contaminated through spray drift exposure and surface runoff. Spray drift is a critical concern when it comes to environmental hazards. It poses health risks not only to farmers and pesticide applicators, but also to individuals living in nearby farm areas. To address this issue, developing reliable models and techniques for estimating spray drift and reducing its impact has become a crucial and efficient research topic. The current research has three primary objectives: firstly, to estimate the average pesticide application rates, trend analysis, and concentration distribution; secondly, to estimate the temporal variations of pesticide concentrations and identify the areas most likely to be affected by pesticide spray drift close to agricultural fields; and lastly, to develop a model for field spray drift and deposition integration between the OpenAir package for the R programming environment and the AgDRIFT atmospheric model. The drift model, along with precise supervised classifications, allowed for a more accurate estimation of potential drift in agricultural areas at a spatial resolution of 15 m. Additionally, multiple scenarios were conducted to evaluate the potential risks of pesticide drift outside of the target areas. This novel method effectively estimated organophosphate pesticide spray drift over two case studies in Macon County using a combination of OpenAir and AgDRIFT models and remotely sensed data. This method allowed for field simulations within completely defined exposure areas with little prior knowledge of pesticide quantities. This study concluded that 6% of total cropland is in danger of pesticide spray drift, with around 8% of crop areas exposed to potential strong drift on land use. Furthermore, 11% of cropped land is vulnerable to moderate drift, whereas around 75% of land use land cover is not vulnerable to pesticide drift. Through this research, an accurate and efficient approach has been developed to estimate spray drift and reduce its impact in agricultural areas, contributing to a safer and healthier environment for all.

Agricultural and medical insect pests are damaging edible crops, spreading diseases, and harming non-target fauna and flora. Prominent polyphagous insect pests harass farmers in the agronomy sector, causing uncountable revenue corrosion. Ecofriendly phytopesticides can avoid the consequences of the bulk usage of synthetic chemicals. In this study, the toxic effect on third-instar larvae of four different insect species (Spodoptera litura, Helicoverpa armigera, Aedes vittatus, and Anopheles subpictus) and the bio-toxicity on non-target fauna (NTF) (Stegodyphus sarasinorum and Gambusia affinis) were evaluated using Matricaria chamomilla (Mc) essential oil (EO) and its major phytoconstituents (Mc-MPCs). GC–MS analysis of the studied M. chamomilla EO gathered 39 constituents, with (E)-β-Farnesene (24.3%), Germacrene D (9.4%), and α-Bisabolol oxide A (10.2%) accounting for the major constituents. Remarkable larval death was seen in H. armigera and Ae. vittatus. In addition, (E)-β-Farnesene, Germacrene D, and α-Bisabolol oxide A exhibited a relevant maximum toxic effect on the target pest’s third-instar larvae. The bio-toxicity of M. chamomilla EO and Mc-MPCs was tested on terrestrial and aquatic NTF. The LC50 values for S. sarasinorum and G. affinis ranged from 922.65 to 1750.49 µg/mL. M. chamomilla EO and its MPCs evidenced prospective phytopesticidal efficiency on selected agricultural and medical insect pests. Full article
