“…After spraying chlorantraniliprole and difenoconazole with the vegetable oil adjuvant, the cuticular wax of the rice leaf was destroyed, which reduced the hydrophobicity of the rice leaf and facilitated the wetting and penetration of pesticides onto the rice leaf. The amount of chlorantraniliprole and difenoconazole in rice leaves was increased by the vegetable oil adjuvant in the first 2 h [32]. In this study, lime peel oil and orange peel oil are vegetable oil adjuvants [33].…”

This study investigated the efficacy of three spray adjuvants (Coerce, Wetcit, and Silwet408) in enhancing dinotefuran permeation in rice leaves. Different concentrations of these adjuvants were tested using an external standard method. The rice leaf surface was analyzed by using the van Oss–Chaudhury–Good method to establish a link between surface free energy (SFE) and dinotefuran permeation. All of the adjuvants effectively increased dinotefuran permeation in rice leaves, with the highest permeation of 8.496 mg/kg achieved using Wetcit at 1000 mg/L. The SFE of the rice leaf surface was determined to be 29.28 mJ/m2. A notable correlation was observed between the energy difference (the SFE of the pesticide liquid versus the SFE of the rice leaf surface) and permeation. Various fitting methods, including linear, exponential, logarithmic, polynomial, and power methods, were applied. Polynomial fitting demonstrated the highest coefficient of determination (R2 > 0.9000). The relationship between the permeation (y) and energy difference (Δγ) conformed to the polynomial equation y = aΔγ2 + bΔγ + c, where a, b, and c are constants. This model provides a predictive tool for the optimal dosage of spray adjuvants according to target plant characteristics, enhancing the understanding of the interaction between pests and pesticides.

“…Triazole fungicides mainly belong to sterol demethylation inhibitor (DMI) fungicides, which occupy an important position in the field of fungicides. Currently, there are dozens of commercialized triazole fungicides in the global market [18, 19], such as, triadimefon [20] (Figure 1), triadimenol [21], tebuconazole [22], hexaconazole [23], prothioconazole [24], epoxiconazole, flusilazole [25], and difenoconazole [26]. Among them, triadimefon is the first widely used triazole fungicide with high efficiency, low toxicity, low residue, long duration, and strong internal absorption, which is effective against a variety of crop diseases such as wheat powdery mildew [27], wheat stem rust [28], and smut [29].…”

Triazole groups play an important role in the construction of agricultural bioactive molecules, often acting as linking units to organically graft different pharmacophore groups, so as to obtain efficient and broad‐spectrum pesticide molecules. After decades of development, triazole derivatives have made remarkable achievements in the discovery of pesticides, especially the discovery of fungicides. In addition, highly effective triazole insecticides, herbicides, and anti‐plant virus agents have also been found, and commercial triazole pesticides have occupied a large market share. At present, the study of triazole compounds has become one of the important fields in the development of new pesticides. We systematically reviewed the application of triazole derivatives in the discovery of new pesticides since 2010, summarized the antifungal, antibacterial, insecticidal, herbicidal, and anti‐plant virus activities of triazole derivatives, and discussed the structure–activity relationship and mechanism of action in order to provide inspiration and ideas for the discovery of new triazole agrochemicals.

BACKGROUNDCitrus huanglongbing (HLB) is a devastating disease in citrus, caused by Candidatus Liberibacter asiaticus (CLas), which primarily resides in the phloem where chemicals cannot effectively reach, posing a significant challenge in controlling HLB. To address these challenges, plant essential oils (EOs), widely used as transdermal enhancers and known for their benefits for plant tissues, were investigated for their potential to enhance chemical permeation.RESULTSIn this study, seven EOs – eugenol, carvacrol, eucalyptol, geraniol, linalool, cinnamaldehyde, and d‐limonene – were evaluated for their potential to enhance chemical penetration into citrus leaves. Preliminary screening with tracer methods revealed that geraniol provided the greatest enhancement of permeation, achieving the deepest and broadest distribution into the spongy tissue of the citrus leaf. The permeation levels of rhodamine B and crystal violet through the cuticular layer were elevated from 0.55 mg L−1 and 0.11 mg L−1 to 20.04 mg L−1 and 7.14 mg L−1, respectively, by the addition of geraniol. Further validation through high‐performance liquid chromatography–mass spectrometry (HPLC–MS) confirmed that the penetration of fludioxonil and tetracycline into citrus leaf tissues was enhanced by 15.07‐fold and 20.43‐fold, respectively. In planta experiments confirmed that adding geraniol to tetracycline and oxytetracycline via foliar application eliminated CLas bacteria in HLB‐affected citrus more efficiently than controls.CONCLUSIONOur study underscores the potential of geraniol as an effective EO‐based permeation enhancer for combating HLB. By significantly improving the delivery and efficacy of bactericidal treatments, geraniol offers a promising strategy for managing this catastrophic citrus disease, potentially transforming the approach to controlling HLB. © 2024 Society of Chemical Industry.
