“…The presence of pathogens such as Rhizoctonia solani which causes soybean sheath blight often leads to secondary infections such as root rot, leaf blight, and various other diseases. This in turn, results in severe yield losses and food safety concerns. − In many cases, chemical fungicides are applied to control these diseases. − However, the extensive use of conventional synthetic pesticide formulations raises significant concerns related to health, environment, and the development of pesticide resistance. − Increasing food safety demands have led to the search for healthier and environmentally friendly alternatives. − …”

As an alternative to synthetic pesticides, essential oils can be used to treat various diseases that affect food safety, such as soybean sheath blight, which poses fewer health and environmental risks. However, conventional formulations, such as emulsions, often bounce, drift, and splash, which results in low pesticide utilization. The splashing phenomenon is especially serious on the hydrophobic soybean leaf surface, leading to the ineffective utilization of pesticide formulations. To this end, our goal is to develop a formulation with exceptional wetting and spreading properties on hydrophobic soybean leaf surfaces by using nanotechnology. We have successfully constructed anise oil nanoemulsions (AO NEs) as an alternative to conventional emulsion formulations. Anise oil microemulsion and anise oil submicroemulsion were selected as control groups to study the spreading performance of emulsions with different sizes. With smaller particle sizes, AO NE exhibited significantly improved wetting and spreading characteristics on the hydrophobic surface of soybean leaves. It also demonstrated excellent inhibition against the pathogen Rhizoctonia solani. AO NE effectively addresses the rebound and spatter problems of traditional emulsions without the addition of extra additives. The agricultural applications of nanoemulsions for delivering essential oils have great potential to increase pesticide utilization.

Twenty 1,4-pentadiene-3-one derivatives containing quinazolinone (W1–W20) were designed and synthesized. The bioactivity test results showed that some compounds had antifungal activities in vitro. W12 showed excellent bioactivity against Sclerotinia sclerotiorum (S. sclerotiorum) and Phomopsis sp., with EC50 values of 0.70 and 3.84 μg/mL, which are higher than those of the control drug azoxystrobin at 8.15 and 17.25 μg/mL. In vivo activity tests were carried out on oilseed rape and kiwifruit. The protective effect of W12 on oilseed rape infected with S. sclerotiorum (91.7 and 87.3%) was better than that of azoxystrobin (90.2 and 79.8%) at 100 and 50 μg/mL, respectively, and the protective effect on kiwifruit infected with Phomopsis sp. (96.2%) was better than that of azoxystrobin (94.6%) at 200 μg/mL. Scanning electron microscopy results showed the hyphae of S. sclerotiorum treated with compound W12 abnormally collapsed and shriveled, inhibiting the growth of mycelium and, thus, laying the inhibiting effect on S. sclerotiorum. The results of the mechanism research showed that the action of W12 changed the mycelial morphology of S. sclerotiorum, affected the permeability of cells, increased the leakage of cytoplasm and allowed the cell membrane to break down. This study shows that 1,4-pentadiene-3-one derivatives containing quinazolinone have good effects on plant fungi and the potential for becoming new fungicides.
