Applications of nanotechnology in biopesticides could achieve controlled release, increase the solubility, and exhibit location targeting strong compatibility.
Nanopesticides are considered to be a promising alternative strategy for enhancing bioactivity and delaying the development of pathogen resistance pesticides. Here, new type nanosilica fungicide was proposed demonstrated control late blight by inducing intracellular peroxidation damage Phytophthora infestans, associated with potato blight. Results indicated that structural features different silica nanoparticles were largely responsible their antimicrobial activities. Mesoporous (MSNs)...
The engineering of pharmaceutical cocrystals has been effectively utilized to improve the physicochemical properties such as stability and solubility, thus it could optimize solid formations active ingredients. This work focuses on sulfamethazine–p-aminobenzoic acid (STH–PABA) cocrystal regulated by molecular synthons constructed from mutual N···H···O interactions. STH–PABA was produced means slow evaporation crystallization method, structure determined through X-ray crystallography....
Abstract BACKGROUND Citrus canker caused by Xanthomonas citri subsp. (Xcc) is a devastating bacterial disease that reduces citrus yield and quality, posing serious threat to the industry. Several conventional chemicals have been used control canker. However, this approach often leads excessive use of chemical agents, can exacerbate environmental pollution promotes development resistant Xcc. Therefore, there significant interest in efficient environmentally friendly technologies RESULTS In...
Abstract BACKGROUND Citrus canker, a bacterial disease caused by Xanthomonas citri subsp. (Xcc), is one of the major threats to citrus industry. Inorganic copper (Cu) formulations such as Bordeaux mixture and Kocide 3000 are currently used control canker; however, they poorly water‐soluble have negligible plant transport, making systemic treatment canker difficult. RESULTS This study synthesized Cu 2 O@His one‐pot self‐assembly 2+ histidine for controlling canker. The results showed that had...
In the present study, we used CaCO3 nanoparticles (CCNPs) as carriers to assess physicochemical characteristics and antibacterial effect of gentamicin sulfate (GS)-loaded CCNPs (CGPs). The results indicated that had relatively regular chain-like structure, size crystallites was around 62.5 nm. FT-IR analysis GS could effectively load onto CCNPs. Meanwhile, dosage would affect drug loading entrapment efficiency GS. prolong release GS, complete from extended up 24 h. Additionally, obviously...
The green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), is an economically devastating crop pest worldwide. M. (SEF-R) population of a cabbage field in China was tested for susceptibilities to 13 insecticides. Compared with the susceptible (FFJ-S), extremely high and resistance beta-cypermethrin (324-fold) imidacloprid (106.9-fold) detected SEF-R. More importantly, this first report sulfoxaflor (32.4-fold), flupyradifurone (9.5-fold), pymetrozine (34.8-fold), spirotetramat...
The traditional Bacillus thuringiensis (Bt) formulations for field applications are not resistant to harsh environmental conditions. Hence, the active ingredients of Bt bioinsecticides could degrade quickly and has low anti-ultraviolet ability in field, which significantly limits its practical application. In present study, we developed an efficient stable delivery system Cry11Aa toxins. We coated proteins with Mg(OH)2 nanoparticles (MHNPs), then assessed effects MHNPs on bioactivity...
Bacillus thuringiensis (Bt) can produce Cry proteins during the sporulation phase, and protein is effective against lepidopteran, coleopteran, dipteran insects nematodes. However, tends to be discharged into soil nontarget plants through rainwater runoff, leading reduced period toward target insects. In present study, nano-Mg(OH)2 (magnesium hydroxide nanoparticles, MHNPs) were synthesized control loss of Cry1Ac deliver Helicoverpa armigera (Lepidoptera: Noctuidae). The results showed that...
Herbicides play an important role in weed control when it comes to ensuring a high and consistent yield agriculture, but their effectiveness is often compromised by climatic variables. Therefore,...
Azole and benzimidazole fungicides are widely used agrochemicals to prevent treat fungal growth frequently detected in aquatic environments. Here, we aimed assess the ecological risks of ten currently azole fungicides, which with aryl hydrocarbon receptor (AhR) agonistic activity, their transformation products (TPs). We obtained over 400 types aerobic TPs for fungicides. Some (approximately 26.7%) exhibited potential AhR activity toxicity different species. Meanwhile, some compounds chlorine...
In the laboratory, an acaricide-susceptible strain of citrus red mite, Panonychus citri (McGregor) (LS-FJ), was used to screen for resistance spirotetramat. A spirotetramat-resistant (ST-NK) obtained after continuous selections through 15 selection cycles (45 generations) exhibited 1668.4-fold greater when compared parent generation. Instability spirotetramat in mites observed during 11 months under spirotetramat-free laboratory conditions. Cross-resistance spirodiclofen and spiromesifen...
Nano-Mg(OH) 2 , with low biological toxicity, is an ideal nano-carrier for insecticidal protein to improve the bioactivity. In this work, adsorption features of by nano-Mg(OH) have been studied. The capacity could reach as high 136 mg g −1 and isotherm had fitted Langmuir Freundlich models. Moreover, kinetics followed a pseudo-first or -second order rate model, was spontaneous exothermic process. However, temperatures are not suitable adsorption, which implies that temperature would be...
Diaphorina citri Kuwayama (Hemiptera: Liviidae), commonly known as the Asian citrus psyllid, is a prominent tree pest that serves vector for huanglongbing (HLB). The substantial costs incurred by industry consequence of this disease have spurred considerable interest in combined control D. using insecticides and natural enemies. However, successful implementation such integrated management strategies dependent on ensuring compatibility enemies presence insecticides. In regard, we evaluated...
In this study, a spherical silica nanoparticle was explored as gatifloxacin carrier synthesized by the chemical precipitation method. It found that there no new bond formation during loading process between and silica, which implies binding driven physical interaction. addition, drug encapsulation efficiency could be improved appropriately increasing nano-silica content in process. Meanwhile, release rate of after also improved, suggesting successful design controlled-release delivery...
Neonicotinoid resistance is increasingly prevalent in the agricultural pest
The green peach aphid, Myzus persicae, is a notorious pest worldwide. We collected field population of the (FZQ-F) that exhibited high resistance to neonicotinoids. Exposure neonicotinoids can induce oxidative damage in animals; however, it remains unclear whether antioxidant enzymes contribute innate immune response neonicotinoid-resistant pests against doses insecticides. Treatment with sublethal thiacloprid (LC10 and LC25) for 3, 6, 12, 24, 48, 72 h resulted significantly increased...
