“…It has advantages such as a wide fungicidal spectrum, long duration, rainfall resistance, and low systemic absorption. It can interrupt the production of fungal cell energy through the uncoupling of oxidative phosphorylation and inhibit pathogenic spore germination, mycelial growth, and spore formation; it plays an important role in the control of various fungal diseases such as Alternaria , Botrytis , and Phytophthora 38–40 . It is currently widely used globally in the prevention and treatment of plant diseases.…”

BACKGROUNDThe use of pesticides in greenhouse vegetable cultivation is necessary and significant. However, traditional pesticide application methods such as the use of backpack sprayers with water‐diluted pesticides have certain drawbacks, e.g., uneven distribution, high labor intensity, and safety risks.RESULTSIn this work, fluazinam ultra‐low‐volume liquids (Flu‐ULVs) were prepared using oily solvents as carriers. The effects of different oils on the physical properties of the preparations were investigated. The Flu‐ULV can be sprayed directly using a hand‐held ultra‐low‐volume (ULV) sprayer without dilution with water. Compared with commercial water‐based suspension concentrates of fluazinam, the Flu‐ULV samples showed better wetting of tomato leaves, better atomization, and more uniform droplet distribution. At a dosage of 300 mL/ha, the coverage rate of tomato leaves ranged from 32.47% to 79.3%, with a droplet deposition density of 556 to 2017 droplets/cm2. Application of Flu‐ULVs provided 70.86% control efficacy against gray mold in tomatoes, which was higher than those achieved with reference products. Dermal exposure to Flu‐ULVs was also evaluated in greenhouse experiments. The coverage rates for all parts of the operator's body ranged from 0.02% to 0.07%, with deposition volumes of 2.23 to 12.26 μg/cm2.CONCLUSIONGround ULV spraying of fluazinam was proved to be an effective and safe management option for the control of tomato gray mold in greenhouses. This study laid a foundation for the use of ultra‐low volume spray to control vegetable diseases in greenhouse, especially those induced by high humidity environment. © 2024 Society of Chemical Industry.
