Case Study

Determination of Meptyldinocap Fungicide in Cucumber and Soil

Zhang, Zhiyong, et al Pest management science, 2014, 70(1), 97-102.

Meptyldinocap is a fortified product of the methylheptyl isomer of single dinitro-octylphenyl crotonate (2,4-DNOPC). It is a new powdery mildew fungicide with both protectant and post-infection activity. In this work, a method using LC-MS/MS was developed to determine 2,4-DNOPC in cucumber and soil. Its degradation pattern and residual level in cucumber and soil were also studied.
Evaluation methods and results
· In the LC-MS/MS determination, the mobile phase A consisted of a mixture of water and methanol along with 0.01 M ammonium formate and 0.1% formic acid, while mobile phase B comprised 0.1% formic acid in methanol. The ratio of mobile phase A to mobile phase B was 90:10 (v/v), and the flow rate was maintained at 0.4 mL min-1. The detection was conducted in electrospray positive ionization using multiple reaction monitoring (MRM) mode. Meptyldinocap's retention time under optimized conditions was approximately 2.7 min
· The recovery rates of meptyldinocap from cucumber and soil samples ranged from 81.4% to 95.1%. The quantification limits were determined to be 0.01 mg kg-1 for both cucumber and soil. The half-lives of meptyldinocap were observed to range between 1.6 and 2.2 days in cucumbers and between 3.1 and 4.4 days in soils. Residue levels of meptyldinocap in cucumbers were between less than 0.01 mg kg-1 and 0.92 mg kg-1, while in soils, they ranged from below 0.01 mg kg-1 to 0.53 mg kg-1. Five days after application, the residue levels of meptyldinocap in cucumbers across all treatments were below 0.1 mg kg-1.

Evaluation of the Biological Efficacy of Meptyldinocap Against Chilli Powdery Mildew

Jain, Y. K., et al. Indian Journal of Horticulture, 2010, 67(4), 292-294.

The biological efficacy of 35% meptyldinocap 35% EC (DE-126) against chilli powdery mildew (Leveillula taurica (Lev.) Arn.) was evaluated and compared with other fungicides.
Experimental design and evaluation results
· The experiment was designed using a randomized block format with three replications. The crop was planted with a spacing of 60×45 cm (row by plant) and all recommended agronomic practices were implemented to ensure healthy growth. The treatments tested included meptyldinocap 35% EC (DE-126) applied at rates of 90, 108, and 120 g a.i./ha, triadimefon 25% WP at 38 g a.i./ha, dinocap 48% EC at 108 g a.i./ha, sulphur 80% WP at 2500 g a.i./ha, and an untreated control. Each treatment received three sprays at 20-day intervals, beginning with the onset of disease symptoms, utilizing a knapsack sprayer with a spray volume of 600 liters per hectare. The significant differences among treatments were assessed through analysis of variance (ANOVA) and least significant difference (LSD) calculations.
· The results indicate that meptyldinocap 35% EC (DE-126) at 120 g a.i./ha was notably effective in managing powdery mildew, showing the lowest disease intensities of 8.52% in 2006-07 and 8.87% in 2007-08. Similarly, meptyldinocap 35% EC (DE-126) at 108 g a.i./ha also performed well, with disease intensities of 10.37% in 2006-07 and 13.33% in 2007-08, demonstrating comparable efficacy.
