“…Furthermore, potassium salts of fatty acids and garlic oil proved effective in reducing leaf-feeding damage. In the case of garlic oil, it has been proven that it has potent spatial repellency against Aedes aegypti adult mosquitoes, in medical entomology and in combating the transmission of tropical viral diseases [70]. Among the low-toxic synthetics that we tested, potassium salt fatty acids, a type of insecticidal soap, is known for exhibiting dual functionality, serving as an insecticide and herbicide, effectively targeting soft-bodied insects and weeds when directly applied.…”

In 2020, the invasive Thrips parvispinus (Karny) was first detected in Florida, United States. In response to the implemented regulatory restrictions, we conducted laboratory experiments under containment conditions. Thrips larvae and adults were exposed to 32 products (conventional and biorational insecticides) either directly or indirectly. Direct exposure was performed using a Spray Potter Tower, while indirect exposure was conducted by evaluating residue toxicity against the thrips. Water served as a control. We assessed mortality and leaf-feeding damage 48 h post-treatment. Among the conventional insecticides, chlorfenapyr, sulfoxaflor-spinetoram, and spinosad caused high mortality across all stages in both direct and residue toxicity assays. Pyridalyl, acetamiprid, tolfenpyrad, cyclaniliprole-flonicamid, acephate, novaluron, abamectin, cyantraniliprole, imidacloprid, cyclaniliprole, spirotetramat, and carbaryl displayed moderate toxicity, affecting at least two stages in either exposure route. Additionally, chlorfenapyr, spinosad, sulfoxaflor-spinetoram, pyridalyl, acetamiprid, cyclaniliprole, cyclaniliprole-flonicamid, abamectin, and acephate inhibited larvae and adult’s leaf-feeding damage in both direct and residue toxicity assays. Regarding biorational insecticides, mineral oil (3%) and sesame oil caused the highest mortality and lowest leaf-feeding damage. Greenhouse evaluations of spinosad, chlorfenapyr, sulfoxaflor-spinetoram, and pyridalyl are recommended. Also, a rotation program incorporating these products, while considering different modes of action, is advised for ornamental growers to avoid resistance and to comply with regulations.

“…[13] In the field of pesticides, the active ingredients in GEO had mosquito-repellent, insecticide, and anti-bacterial effects. [14] Figure 1 presents the structures of some commercially available organic sulfur-based fungicides, which contain fragments of sulfides or sulfones. Garlic essential oil (GEO) contains various sulfide components, making it meaningful to explore the inhibitory capacity and broad-spectrum activity of garlic oil against phytopathogenic fungi.…”

Garlic oil has a wide range of biological activities, and its broad‐spectrum activity against phytopathogenic fungi still has the potential to be explored. In this study, enzymatic treatment of garlic resulted in an increase of approximately 50 % in the yield of essential oil, a feasible GC‐MS analytical program for garlic oil was provided. Vacuum fractionation of the volatile oil and determination of its inhibitory activity against 10 fungi demonstrated that garlic oil has good antifungal activity. The antifungal activity levels were ranked as diallyl trisulfide (S‐3)>diallyl disulfide (S‐2)>diallyl monosulfide (S‐1), with an EC50 value of S‐3 against Botrytis cinerea reached 8.16 mg/L. Following the structural modification of compound S‐3, a series of derivatives, including compounds S‐4~7, were synthesized and screened for their antifungal activity. The findings unequivocally demonstrated that the compound dimethyl trisulfide (S‐4) exhibited exceptional antifungal activity. The EC50 of S‐4 against Sclerotinia sclerotiorum reached 6.83 mg/L. SEM, In vivo experiments, and changes in mycelial nucleic acids, soluble proteins and soluble sugar leakage further confirmed its antifungal activity. The study indicated that the trisulfide bond structure was the key to good antifungal activity, which can be developed into a new type of green plant‐derived fungicide for plant protection.

“…Therefore, prior research is needed to determine the most suitable compounds or mixtures of compounds for effectively eliminating different pests and producing more precise CBs. Some studies have explored the use of compounds present in essential oils or plant extracts to combat various types of pests, such as cabbage looper [7], Spodoptera littoralis larvae [8,9], mosquitoes [10,11], and other insects [12][13][14][15]. The efficacy of binary mixtures of aromatic compounds against some insects was also evaluated.…”
