Although the chemical inputs improved the crop production, it is well known about their negative effects, such as environmental residues in water, soil and animals, pest resistance and resurgence and the residues in agricultural produces. The demands for safer food and more friendly environment are now more preferred by humankind in the world. Microbes have already become an alternate for chemical inputs in some aspects in agriculture. The microbes can produce very diverse volatile organic compounds (mVOCs) which play important roles in the interactions between plant and microbes, or among intraspecies or interspecies of microbes. Many mVOCs showed diverse agroactivities, such as insecticidal, bactericidal, fungicidal, herbicidal, plant growth promotion and abiotic stress-tolerance inducing activities. The agroactive mVOCs have diverse structure-types, such as alkane, alkenes, alcohols, aldehydes, ketones, carboxylic acid, esters and lactones, ethers, aromatic ring, terpenes, heterocycles, sulphur-containing VOCs. The promising agroactive properties make it possible to apply mVOCs and their producing microorganisms or synthetic mimics or agroactive mVOCs in crop protection, and so this review focuses on the chemical diversity, agroactivities, and potential application of mVOCs.</p></div>","PeriodicalId":100027,"journal":{"name":"Advanced Agrochem","volume":"2 1","pages":"Pages 39-57"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a green and facile method is described to biosynthesize nano-silver chloride with excellent antibacterial activity via in situ reduction of Ag ⁺ using the extract of <em>Bacillus thuringiensis</em> (Bt). Compared with previous reports, the minimal inhibition concentration (MIC) against <em>Escherichia coli</em> (<em>E. coli</em>) is 3.0 μg/mL, which is 2– to 800-fold higher than that of nano silver chloride. Subsequent <em>in vitro</em> studies involving agricultural bacteria such as <em>Ralstonia solanacearum</em> (<em>R. solanacearum</em>) revealed a 92.95% antibacterial rate when the concentration of nano-silver chloride was 2.0 μg/mL. Previous studies of antibacterial activity of nano-silver chloride focused more on the basic antibacterial properties without describing its antibacterial molecular mechanisms. The microscopic investigations and DNA damage experiments indicated that the nano-silver chloride adsorbed to the bacterial surface, leading to cell wall rupture, DNA damage, and cytoplasmic leakage. In addition, electron paramagnetic resonance (EPR) spectroscopy indicated the synthesis of reactive oxygen species (·OH, ·O²⁻ and ¹O₂) in the bacteria. Our study provides evidence supporting the use of nano-silver chloride as an antibacterial agent in agriculture, and theoretical insight into the antibacterial mechanism thereof.</p></div>","PeriodicalId":100027,"journal":{"name":"Advanced Agrochem","volume":"2 1","pages":"Pages 88-96"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49728364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To cultivate healthier crops, manage pests, monitor soil and growing conditions, analyse data for farmers, and enhance other management activities of the food supply chain, the agriculture sector is turning to AI technology. It makes it challenging for farmers to choose the ideal time to plant seeds. AI helps farmers choose the optimum seed for a particular weather scenario. It also offers data on weather forecasts. AI-powered solutions will help farmers produce more with fewer resources, increase crop quality, and hasten product time to reach the market. AI aids in understanding soil qualities. AI helps farmers by suggesting the nutrients they should apply to increase the quality of the soil. AI can help farmers choose the optimal time to plant their seeds. Intelligent equipment can calculate the spacing between seeds and the maximum planting depth. An AI-powered system known as a health monitoring system provides farmers with information on the health of their crops and the nutrients that need to be given to enhance yield quality and quantity. This study identifies and analyses relevant articles on AI for Agriculture. Using AI, farmers can now access advanced data and analytics tools that will foster better farming, improve efficiencies, and reduce waste in biofuel and food production while minimising the negative environmental impacts. AI and Machine Learning (ML) have transformed various industries, and the AI wave has now reached the agriculture sector. Companies are developing several technologies to make monitoring farmers' crop and soil health easier. Hyperspectral imaging and 3D laser scanning are the leading AI-based technologies that can help ensure crop health. These AI-powered technologies collect precise data on the health of the crops in greater volume for analysis. This paper studied AI and its need in Agriculture. The process of AI in Agriculture and some Agriculture parameters monitored by AI are briefed.
