Marrone Bio Innovations, Inc., a leading global provider of bio-based pest management and plant health products formally introduces REGALIA® Rx, an advanced, broad-spectrum biofungicide that improves plant health and increases yield potential. REGALIA® Rx is registered for use in corn, soybeans, wheat, rice, and other row crops.

Adding just one pint of REGALIA Rx to an existing fungicide program improved overall plant health and yields. Applications to both corn and soybeans produced plants with more extensive root systems, larger, fuller ears of corn, bigger and greener soybean plants and overall better yields. Similar yield response and plant health improvements were demonstrated in rice, wheat and barley trials during the same timeframe.

“The average yield increase across the REGALIA Rx trials-university and on-farm-was six bushels/acre in corn and two bushels/acre in soybeans compared to the standard fungicide program,” states Dr. Tim Johnson, Global Product Development Director for Marrone Bio Innovations.

“Adding REGALIA Rx to the fungicide program earlier in the season gives crops the optimum performance potential and benefit. In corn, our studies show that one pint of REGALIA Rx applied at the V4 and V8 stages of growth boosted yields significantly more than later season applications at V8 and VT,” explains Dr. Johnson.

The active ingredient in REGALIA Rx, which is derived from a plant extract, triggers plants’ natural defense systems to help protect against disease, improve plant health, combat fungal and bacterial diseases and boost yield potential.

It is the only commercially available fungicide with a FRAC code of P5 so it adds another mode of action to a fungicide program, which improves overall disease control and plant health. Widely recommended as a foliar application, REGALIA Rx is also labeled for use as an effective soil treatment against soil-borne plant diseases.
