“…The main ingredients are 37.5% methicillin, 25% fludioxonil, and 37.5% other auxiliaries. The rice seedling pathogen was applied using a spray inoculation method on all leaves, along with a blank control group [14]. A graded survey was performed according to the incidence of disease symptoms on the leaves, and the disease index was calculated [15,16].…”

Traditional rice seed coating agents (TRSCA) contain toxic components that pollute the environment and threaten human health. The use of safe, high-efficiency, and environmentally friendly seed coating agents is vital for environmental protection. We studied the production of a new, environmentally friendly rice seed coating agent and its mechanism at the seedling stage. We assess the difference in mechanism of action between the new seed coating agent and the representative TRSCAs on the market through laboratory and field experiments. Following the application of the new seed coating agent, bakanae disease was controlled at a rate of over 80.5% and insect pest feeding was controlled at a rate of 81%. More importantly, the LC50 value was 10 times higher than following TRSCA treatment. The coating agent can enhance the activity of plant protective enzymes (peroxidase [POD], catalase [CAT], and superoxide dismutase [SOD]) and the activity of rice seedling roots. The coating agent is antibacterial, disease preventative, deworming, safe, and environmentally protective, and results in the production of strong seedlings, suggesting it would be a good alternative to TRSCA. Our analysis found that the control effect of the seed coating on rice seedling disease was likely achieved by activating the plant protection enzymes (e.g., POD, CAT, and SOD). The effect of the coating agent on rice is likely achieved through increased root activity and the improvement of the rhizosphere micro-ecological system.

“…Zeng et al [63] prepared a new environmentally friendly seed-coating agent, which is mainly composed of natural polysaccharide polymers, and has harmless characteristics. Field experiments showed that this method increased the corn yield by 17.75%, increased the activity of plant protective enzymes, and increased the content of chlorophyll, achieving the goals of disease prevention, pest control, yield increase, and safety.…”

Seeds comprise an important way in which plant pathogens are introduced into new areas, and serve as carriers for their survival from one planting season to another. Seed health is a recognized factor in modern agricultural science, and affects ideal plant populations and good harvests. Seed disease is one of the most important biological constraints in seed production worldwide. Effective and rapid detection and identification methods for seed disease comprise an important step in crop management, and a measure to protect seeds from pathogens. The detection of seed diseases is usually divided into three categories: traditional detection, immunological detection, and bioinformatics-based detection. The detection methods used for different types of pathogens also vary. For the prevention and control of seed diseases, appropriate methods should also be adopted, such as physical methods, chemical methods, and biological methods. They can be used alone or in combination to achieve the purpose of disease prevention and control. Therefore, this article reviews some important crop seed diseases, their detection and identification methods, and control techniques, in order to provide a theoretical basis for the comprehensive prevention and effective control of seed diseases.

“…Studies have substantiated that this agricultural technology has a beneficial effect in preventing plant diseases, improving the seed germination rate, promoting shoot growth, and increasing both crop yield and quality ( Richard, 2005 ; Wang et al, 2016 ; Mnasri et al, 2017 ; Ren et al, 2019 ). Despite certain advancements, previous research on seed coatings has primarily focused on the use of toxic fungicides, such as carbofuran, which retains pesticide residue, poses risks to human and livestock health, and causes environmental pollution; furthermore, the outcomes are not consistently satisfactory ( Zhu, 2007 ; Zeng et al, 2018 ). The performance requirements for suspension concentrate for seed coating of rice are more stringent due to the prolonged (up to 1–2 months) soaking in water required for rice cultivation ( Mnasri et al, 2017 ).…”

The main rice planting areas in the middle and lower reaches of the Yangtze River are primarily affected by two types of rice seedling diseases: bakanae disease and seedling rot disease. These diseases lead to considerable losses. Seed coating technology effectively protects rice from these diseases and mitigates environmental pollution. We determined the antifungal activity of six fungicides, including phenamacril, azoxystrobin, fludioxonil, metconazole, thifluzamide and prothioconazole against Fusarium moniliforme Sheldon and Curvularia lunata in this study. In addition, the impact of fungicides and surfactants on rice seed germination were determined. Furthermore, phenamacril and fludioxonil were selected as the active components of suspension concentrate for seed coating. The antifungal activity of phenamacril against F. moniliforme Sheldon was 0.139 mg/L and fludioxonil against C. lunata was 0.110 mg/L. PEG-2000 was selected as the surfactant due to its promoting effect on rice seedling. Based on the above findings, 6% phenamacril fludioxonil FS was developed via the wet sand grinding method. The toxicity of 6% phenamacril fludioxonil FS to zebrafish was verified, and field experiments were conducted in five different regions of the Yangtze River Basin. The results indicated minimal toxicity of 6% phenamacril fludioxonil FS to zebrafish. Relative to the control agent consisting of 6.25% phenamacril metalaxyl-M FS, 6% phenamacril fludioxonil FS showed better control effect and exhibited superior efficacy in promoting growth and increasing yield in all five regions. Specifically, the control effect of 6% phenamacril fludioxonil FS on bakanae exceeded 84.83% with the highest yield increasing value recorded at 30.48%. Currently, the market offers a limited selection of suspension concentrate for seed coating of rice. The findings of this study may offer a viable alternative formulation and directions for further research concerning the application of suspension concentrate for seed coating of rice.
