50%溴硝醇湿拌种剂的制备及对果斑病的防效评价
Preparation and Evaluation of 50%Bronopol WS for Controlling Bacterial Fruit Blotch of Melon
摘要
Abstract
Bacterial fruit blotch on melon is a highly destructive seed-borne disease.To enhance the prevention and management of this disease,this study developed a highly efficient and low-toxicity wet seed dressing agent and assessed its quality parameters and efficacy.Through the evaluation of the inhibitory effects of five different compounds on seeds with Acidovorax citrulli,it was determined that a 50%bromoxynil wet seed dressing agents exhibits a 100%bactericidal effect against these pathogens.The test results indicate that the 50%bronopol wet seed treatment agent complies with all the required physical and chemical performance specifications outlined in the relevant national standards(GB/T 1601-1993,GB/T 14825-2006,GB/T 5451-2001,GB/T 16150-1995,and GB/T 28142-2011).High-performance liquid chromatography(HPLC)analysis further revealed that the degradation rate of the active ingredient in the wet seed treatment formulation is below 5%,meeting national standards.An in vitro pot experiment demonstrated that when applied at a 1∶200 ratio,the 50%bromoxynil wet seed treatment formulation resulted in zero disease incidence in seedborne sweet melon,while also ensuring crop safety.This research contributes an efficacious and secure formulation for controlling bacterial fruit spot disease in cucurbits,thereby mitigating the risk of seed-mediated transmission.关键词
