Hybrid fungicide shows promise in controlling early blight

A new hybrid fungicide combining botanical and conventional chemistries has shown promising results in controlling early blight and boosting yields.

Results from a 2022 North Dakota State University trial using REGEV found efficacy against brown spot, early blight and gray mold, according to a news release. REGEV. a combination of tea tree extract and difenoconazole, uses eight mechanisms with one residue.

Except Echo Zn and Manzate ProStick, all programs included Echo Zn (1,3,4,6,8-10), Quadris (2), and Manzate Pro-Stick (2,5,7) Application Rates: Regev 7oz; Echo Zn 34oz; Quadris 9oz; Manzate ProStick 2lb; Scala 7oz; Luna Tranquility 11.2oz; Revus Top 5.6oz; Provysol 4oz.

With preventative and double kick-back curative activity, REGEV is effective against a variety of bacterial and fungal diseases in a range of arable crops, fruit and vegetables, according to the release. Farmers using REGEV can reduce synthetic pesticide usage while maintaining a strong resistance management program.

Tea tree extract’s combination of terpenes act on fungal pathogens by disrupting their cell membranes and inhibiting sporulation, spore germination, respiration, ion transport and mycelial growth. The extract also fights bacterial pathogens by inhibiting the infection process, with difenoconazole reinforcing the tea tree extract by inhibiting fungal ergosterol biosynthesis.

REGEV is sold through Helena Agri-Enterprises and Tenkoz member companies.
